After decades of Moore&#8217;s Law scaling that made transistors progressively smaller on a single planar chip, the physical and economic limits of 2D scaling are driving the industry toward a third dimension. Three-dimensional integration \u2014 stacking multiple chips vertically with high-density interconnects between them \u2014 is now the primary strategy for delivering continued performance and bandwidth improvements in AI accelerators, high-performance computing, advanced memory, and mobile processors.<\/p>\n  <p>In 2026, 3D integration and advanced packaging are no longer niche or future technologies \u2014 they are mainstream production. TSMC&#8217;s CoWoS (Chip-on-Wafer-on-Substrate) and SoIC (System-on-Integrated-Chips) platforms are in volume production for NVIDIA&#8217;s AI accelerators and Apple&#8217;s processors. Intel&#8217;s Foveros 3D stacking is deployed in Core Ultra processors. Samsung&#8217;s X-Cube and SK Hynix&#8217;s High Bandwidth Memory (HBM) use 3D stacking with through-silicon vias. Every one of these platforms depends critically on CMP \u2014 and the CMP requirements of advanced packaging push well beyond what conventional front-end CMP demands.<\/p>\n  <p>This article complements the advanced-node CMP discussion in our article on <a class=\"jl\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/CMP-in-Advanced-Nodes-Challenges-at-7nm-5nm-Beyond\/\" target=\"_blank\" rel=\"noopener\">CMP Challenges at 7nm, 5nm &amp; Beyond<\/a>.

In 3D IC integration, CMP serves the same fundamental function but with requirements that are in some respects far more stringent \u2014 because the surfaces being prepared are the actual bonding interfaces between two or more chips. Any imperfection at these interfaces directly affects bond yield, interconnect resistance, and long-term reliability.<\/p>\n\n  <div class=\"jc-card-grid\">\n    <div class=\"jc-card\">\n      <div class=\"jc-card-icon\">\ud83d\udd17<\/div>\n      <h4>Bonding Interface Prep<\/h4>\n      <p>Hybrid bonding requires copper and dielectric surfaces co-planar within 1\u20132 nm and roughness below 0.3 nm Ra \u2014 the most stringent CMP specification in production today.<\/p>\n    <\/div>\n    <div class=\"jc-card\">\n      <div class=\"jc-card-icon\">\ud83d\udd73\ufe0f<\/div>\n      <h4>TSV Reveal<\/h4>\n      <p>Through-silicon vias must be exposed from the wafer backside by thinning and CMP, revealing via tips flush with the backside surface within \u00b150 nm tolerance.<\/p>\n    <\/div>\n    <div class=\"jc-card\">\n      <div class=\"jc-card-icon\">\ud83d\udccf<\/div>\n      <h4>Wafer Thinning<\/h4>\n      <p>3D stacked dies must be thinned from 750 \u00b5m to 50\u2013100 \u00b5m (or even 5\u201320 \u00b5m for extreme stacking) using a grind-then-CMP sequence to achieve target thickness with low damage.<\/p>\n    <\/div>\n    <div class=\"jc-card\">\n      <div class=\"jc-card-icon\">\ud83e\udde9<\/div>\n      <h4>RDL Planarization<\/h4>\n      <p>Redistribution layer (RDL) dielectric and copper CMP in advanced fan-out packaging requires the same dual-damascene CMP as front-end BEOL but on a different substrate.<\/p>\n    <\/div>\n  <\/div>\n\n  <h2 id=\"hybrid-bonding\"><span class=\"acc\"><\/span>Hybrid Bonding CMP: The Most Demanding Application<\/h2>\n  <p>Hybrid bonding is the direct copper-to-copper and dielectric-to-dielectric bonding technology that enables chiplet stacking with sub-micron pitch interconnects \u2014 providing bandwidth densities 100\u20131,000\u00d7 higher than conventional flip-chip bump connections. The bonding process requires two wafers (or a die and a wafer) whose surfaces are so flat and smooth that they spontaneously bond at room temperature through van der Waals attraction and chemical bonding when brought into contact.<\/p>\n  <p>Achieving this requires CMP to deliver a surface that meets four simultaneous specifications \u2014 all more demanding than any production CMP application in the conventional fab:<\/p>\n\n  <div class=\"jc-tech-stack\">\n    <div class=\"jc-tech-row\">\n      <div class=\"jc-tech-label\">Oberfl\u00e4chenrauhigkeit<\/div>\n      <div class=\"jc-tech-content\"><strong>Requirement: Ra &lt; 0.3 nm (3 \u00c5)<\/strong>Any surface roughness above this level prevents intimate atomic contact at the bonding interface, reducing bond strength and leaving voids that create high-resistance or open interconnects. Conventional copper CMP delivers Ra of 0.5\u20132 nm \u2014 insufficient for hybrid bonding. Dedicated low-force buff steps with ultra-fine slurry are required.<\/div>\n    <\/div>\n    <div class=\"jc-tech-row\">\n      <div class=\"jc-tech-label\">Cu-Dielectric Co-planarity<\/div>\n      <div class=\"jc-tech-content\"><strong>Requirement: Height difference &lt; 2 nm<\/strong>The copper bond pads must be co-planar with the surrounding SiCN or SiO\u2082 dielectric within 2 nm. Positive step height (proud copper) pushes the dielectric areas apart and creates voids; negative step height (recessed copper, i.e. dishing) creates voids under the copper pad itself. Both failure modes reduce bond yield.<\/div>\n    <\/div>\n    <div class=\"jc-tech-row\">\n      <div class=\"jc-tech-label\">Within-Wafer Uniformity<\/div>\n      <div class=\"jc-tech-content\"><strong>Requirement: WIWNU &lt; 0.5 nm<\/strong>The height uniformity requirement applies not just locally at individual bond pad sites but globally across the entire 300 mm wafer.

Post-CMP cleaning for hybrid bonding must achieve surface copper below 5\u00d710\u2078 atoms\/cm\u00b2.<\/div>\n    <\/div>\n  <\/div>\n\n  <h3>Hybrid Bonding CMP Process Design<\/h3>\n  <p>Meeting these specifications requires a purpose-designed CMP process that differs significantly from standard copper dual-damascene CMP. The key differences are:<\/p>\n  <ul class=\"jc-ul\">\n    <li><strong>Ultra-low downforce:<\/strong> Polishing pressure must be below 1 psi \u2014 sometimes as low as 0.3\u20130.5 psi \u2014 to avoid mechanical deformation of the copper pad structure and dishing in pad arrays.<\/li>\n    <li><strong>Near-zero dishing slurry:<\/strong> Copper slurry formulated with carefully balanced BTA concentration and oxidiser levels to achieve near-zero copper recess while maintaining adequate removal rate. Many hybrid bonding CMP processes use a two-step sequence: a conventional copper CMP step to clear the bulk overburden, followed by a dedicated &#8220;planarization slurry&#8221; step specifically formulated for co-planarity optimisation.<\/li>\n    <li><strong>Ultra-soft buff pad:<\/strong> A final buff step using a very soft, compliant pad (Shore A 30\u201340) with a colloidal silica or surfactant-only slurry to reduce surface roughness to the &lt;0.3 nm Ra target without re-introducing non-uniformity.<\/li>\n    <li><strong>Dedicated post-CMP clean:<\/strong> A super-clean sequence using dilute NH\u2084OH for particle removal, followed by dilute HCl for metallic contamination control, followed by a high-purity DI water rinse and IPA-assisted drying.<\/li>\n  <\/ul>\n\n  <h2 id=\"tsv-cmp\"><span class=\"acc\"><\/span>Through-Silicon Via (TSV) CMP<\/h2>\n  <p>Through-silicon vias (TSVs) are vertical conductive pillars that electrically connect stacked dies in a 3D IC package. They are formed by etching deep vias (aspect ratios of 10:1 to 20:1) into the silicon, depositing an insulating liner and barrier, filling with copper by electroplating, and then using CMP to remove the overplated copper from the wafer frontside. After the chip is fabricated, the wafer is thinned from the backside until the TSV copper tips are revealed \u2014 a process that also involves a final CMP step to planarize the revealed TSV surface.<\/p>\n\n  <h3>Frontside TSV CMP<\/h3>\n  <p>After TSV copper electroplating, the wafer surface carries 5\u201320 \u00b5m of overplated copper \u2014 far thicker than typical BEOL dual-damascene overburden (0.5\u20131 \u00b5m). Removing this thick copper layer by CMP requires high removal rate (up to 1 \u00b5m\/min) combined with excellent planarity control to avoid the &#8220;dimpling&#8221; effect \u2014 where the top of each TSV copper pillar is polished faster than the surrounding silicon, creating a recessed profile that can cause contact resistance issues. High-pressure, multi-step CMP with dedicated thick-film copper slurries is required.<\/p>\n\n  <h3>Backside TSV Reveal CMP<\/h3>\n  <p>After wafer thinning (by grinding) to expose the TSV backside, a CMP step is used to planarize the thinned silicon surface and reveal the copper TSV tips with a controlled protrusion height \u2014 typically 1\u20133 \u00b5m above the silicon surface. This protrusion is intentional: it allows subsequent backside metallisation to contact the TSV tip reliably. The reveal CMP must stop within \u00b150 nm of the target protrusion height across the entire wafer, requiring slurry with high silicon-to-copper selectivity (to preferentially remove silicon while leaving copper proud) and excellent endpoint detection capability.<\/p>\n\n  <h2 id=\"wafer-thinning\"><span class=\"acc\"><\/span>Wafer Thinning &amp; Backside CMP<\/h2>\n  <p>Three-dimensional stacking requires dies to be thinned from their standard 750 \u00b5m wafer thickness to 50\u2013100 \u00b5m (for standard 3D stacking) or 5\u201320 \u00b5m (for extreme thin-die stacking in HBM and similar applications). The thinning process uses a three-step sequence: rough grinding (to remove bulk silicon rapidly), fine grinding (to achieve the target thickness within \u00b15 \u00b5m), and CMP (to remove the grinding-induced sub-surface damage layer and achieve the surface roughness required for the next step).<\/p>\n\n  <h3>Grinding Damage Removal<\/h3>\n  <p>Diamond grinding leaves a damaged silicon sub-surface layer \u2014 an amorphous or heavily dislocated crystal zone extending 1\u20135 \u00b5m below the ground surface. This damage layer must be completely removed before the thinned wafer can be bonded or further processed, because it increases carrier recombination, reduces mechanical strength (making the die more susceptible to cracking), and introduces residual stress that can cause wafer bow. CMP removes the damage layer and leaves a crystallographically perfect, low-roughness silicon surface ready for backside contact or bonding.<\/p>\n\n  <h2 id=\"cowos-chiplet\"><span class=\"acc\"><\/span>CoWoS, SoIC &amp; Chiplet CMP<\/h2>\n  <p>TSMC&#8217;s CoWoS (Chip-on-Wafer-on-Substrate) and SoIC (System-on-Integrated-Chips) platforms represent the two primary 3D integration architectures in high-volume production as of May 2026. Both require multiple CMP steps \u2014 but with different specifications depending on the integration approach.<\/p>\n\n  <h3>CoWoS Interposer CMP<\/h3>\n  <p>CoWoS uses a silicon or silicon nitride interposer to connect multiple chiplets side-by-side with short, high-bandwidth interconnects. The interposer fabrication process requires a full set of front-end and back-end CMP steps \u2014 oxide ILD, copper dual-damascene, and TSV CMP \u2014 identical to those used in logic chip fabrication. CMP specifications for interposers are similar to but slightly more relaxed than leading-edge logic, as the interposer feature sizes (1\u20135 \u00b5m RDL pitch) are less aggressive than front-end device dimensions.<\/p>\n\n  <h3>SoIC Face-to-Face Bonding CMP<\/h3>\n  <p>TSMC&#8217;s SoIC technology bonds chiplets face-to-face using hybrid bonding \u2014 the most demanding CMP application described in the hybrid bonding section above. In SoIC, two chips with bond pads at their front-side surfaces are brought together and directly bonded copper-to-copper and dielectric-to-dielectric. The CMP surface preparation on both chips must simultaneously meet the &lt;0.3 nm Ra, &lt;2 nm step height, and sub-ppb metal contamination specifications described above.<\/p>\n\n  <h2 id=\"specifications\"><span class=\"acc\"><\/span>Surface Specifications for Bonding: Comparison<\/h2>\n\n  <div class=\"jc-table-wrap\">\n    <table class=\"jc-table\">\n      <thead>\n        <tr>\n          <th>Bonding Technology<\/th>\n          <th>Surface Roughness (Ra)<\/th>\n          <th>Cu-Dielectric Step Height<\/th>\n          <th>WIWNU<\/th>\n          <th>Cu Contamination<\/th>\n          <th>Representative Products<\/th>\n        <\/tr>\n      <\/thead>\n      <tbody>\n        <tr>\n          <td>Conventional flip-chip<\/td>\n          <td>&lt;5 nm<\/td>\n          <td>Not specified<\/td>\n          <td>&lt;5%<\/td>\n          <td>Not critical<\/td>\n          <td>Standard bumped chips<\/td>\n        <\/tr>\n        <tr>\n          <td>Micro-bump bonding<\/td>\n          <td>&lt;2 nm<\/td>\n          <td>&lt;50 nm<\/td>\n          <td>&lt;2%<\/td>\n          <td>&lt;10\u00b9\u00b9 atoms\/cm\u00b2<\/td>\n          <td>HBM2, CoWoS<\/td>\n        <\/tr>\n        <tr>\n          <td>Direct Cu-Cu bonding<\/td>\n          <td>&lt;0.5 nm<\/td>\n          <td>&lt;5 nm<\/td>\n          <td>&lt;1 nm absolute<\/td>\n          <td>&lt;10\u00b9\u2070 atoms\/cm\u00b2<\/td>\n          <td>HBM3, early SoIC<\/td>\n        <\/tr>\n        <tr>\n          <td>Hybrid bonding (SoIC, Foveros)<\/td>\n          <td>&lt;0,3 nm<\/td>\n          <td>&lt;2 nm<\/td>\n          <td>&lt;0.5 nm absolute<\/td>\n          <td>&lt;5\u00d710\u2078 atoms\/cm\u00b2<\/td>\n          <td>NVIDIA H200, Apple M-series<\/td>\n        <\/tr>\n        <tr>\n          <td>Hybrid bonding (sub-1 \u00b5m pitch, future)<\/td>\n          <td>&lt;0.1 nm<\/td>\n          <td>&lt;0.5 nm<\/td>\n          <td>&lt;0.2 nm absolute<\/td>\n          <td>Below TXRF detection limit<\/td>\n          <td>Next-gen AI accelerators (2027+)<\/td>\n        <\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n\n  <h2 id=\"metrology\"><span class=\"acc\"><\/span>Metrology Challenges in Advanced Packaging CMP<\/h2>\n  <p>The sub-nanometre surface specifications of hybrid bonding CMP create metrology challenges that are as significant as the process challenges themselves. Many standard fab metrology tools cannot measure the required specifications with sufficient accuracy or throughput for production monitoring.<\/p>\n  <ul class=\"jc-ul\">\n    <li><strong>AFM for roughness and step height:<\/strong> Atomic force microscopy is the reference method for measuring Ra and Cu-dielectric step height at sub-nm resolution, but its low throughput (one measurement point per minute) makes it impractical for production wafer-level monitoring. New fast-scan AFM systems with automated stage control are improving throughput to 5\u201310 points per minute.<\/li>\n    <li><strong>Optical scatterometry for step height:<\/strong> Advanced optical CD tools with modelling capability can measure Cu step height with ~0.5 nm sensitivity at production-compatible speeds (20\u201350 points per minute). Accuracy at the &lt;2 nm level requires careful optical model calibration against AFM reference data.<\/li>\n    <li><strong>TXRF for surface metal:<\/strong> TXRF remains the standard for surface metal contamination measurement, but its sensitivity limit (~10\u2079 atoms\/cm\u00b2 for Cu) is being pushed by the increasingly stringent hybrid bonding requirements. Next-generation TXRF systems with improved X-ray source brightness are targeting 10\u2078 atoms\/cm\u00b2 sensitivity by 2027.<\/li>\n    <li><strong>Wafer-level bond void inspection:<\/strong> After bonding, void defects at the bonding interface are detected by scanning acoustic microscopy (SAM) or X-ray tomography. SAM sensitivity to sub-5 \u00b5m voids is required for advanced hybrid bonding quality control.<\/li>\n  <\/ul>\n\n  <h2 id=\"outlook\"><span class=\"acc\"><\/span>Market Outlook &amp; JEEZ&#8217;s Role in Advanced Packaging CMP<\/h2>\n  <p>The advanced packaging CMP market is at an inflection point in 2026. What was a niche, specialised application two years ago is now a high-volume production requirement at every major advanced packaging fab. TSMC&#8217;s CoWoS capacity expansion, Intel Foundry&#8217;s Foveros ramp, and the explosive growth of HBM for AI applications are driving rapid volume growth in advanced packaging CMP consumables.<\/p>\n\n  <div class=\"jc-callout\">\n    <div class=\"jc-callout-icon\">\ud83d\ude80<\/div>\n    <div class=\"jc-callout-body\">\n      <h4>JEEZ in advanced packaging CMP<\/h4>\n      <p>Jizhi Electronic Technology Co., Ltd. (JEEZ) is actively developing and qualifying CMP slurry and polishing pad products for advanced packaging applications \u2014 including hybrid bonding surface preparation, TSV CMP, and RDL planarization. Our engineering team works directly with packaging fabs and OSATs to develop application-specific formulations and qualify consumables that meet the stringent surface specifications required for production hybrid bonding. <a class=\"jl\" href=\"https:\/\/jeez-semicon.com\/de\/contact\/\" target=\"_blank\" rel=\"noopener\">Contact JEEZ<\/a> to discuss your advanced packaging CMP requirements.<\/p>\n    <\/div>\n  <\/div>\n\n  <p>The competitive dynamics of the advanced packaging CMP consumables market are distinct from the established logic and memory CMP segments. Hybrid bonding CMP is a new application where no incumbent supplier has a dominant position \u2014 creating an opportunity for technically capable suppliers like JEEZ to qualify alongside established leaders. The key differentiators in this segment are application engineering depth (ability to co-develop process recipes with packaging fabs), surface specification capability (ability to consistently meet Ra &lt;0.3 nm and step height &lt;2 nm requirements), and supply reliability. These are precisely the capabilities that JEEZ is building for the advanced packaging CMP market through 2026 and beyond.<\/p>\n\n  <div class=\"jc-related\">\n    <div class=\"jc-related-title\">Related Articles in This Series<\/div>\n    <div class=\"jc-related-grid\">\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/cmp-semiconductor-the-complete-guide-to-chemical-mechanical-planarization\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83d\udcd6<\/span>CMP Complete Guide (Pillar)<\/a>\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/CMP-in-Advanced-Nodes-Challenges-at-7nm-5nm-Beyond\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83d\udd2c<\/span>CMP at Advanced Nodes<\/a>\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/CMP-Slurry-Guide-Types-Selection-Optimization\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83e\uddea<\/span>CMP Slurry Guide<\/a>\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/CMP-Polishing-Pad-Types-Selection-Performance-Guide\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83d\udcbf<\/span>CMP Polishing Pad Guide<\/a>\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/Post-CMP-Cleaning-Methods-Challenges-Best-Practices\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83e\udee7<\/span>Post-CMP Cleaning<\/a>\n      <a class=\"jc-related-link\" href=\"https:\/\/jeez-semicon.com\/de\/blog\/CMP-Defect-Types-Root-Causes-Yield-Improvement\/\" target=\"_blank\" rel=\"noopener\"><span class=\"ico\">\ud83d\udd0d<\/span>CMP Defects &amp; Yield<\/a>\n    <\/div>\n  <\/div>\n\n  <div class=\"jc-cta\">\n    <h3>Developing CMP Processes for Advanced Packaging?<\/h3>\n    <p>JEEZ supplies and develops CMP consumables for hybrid bonding, TSV, wafer thinning, and RDL applications.
