For mainstream 200 mm and 300 mm silicon prime wafer applications running on well-established machine platforms \u2014 Strasbaugh 6EC, Peter Wolters AC Series, Speedfam 9B \u2014 catalog templates from established suppliers perform reliably. The geometry is well-characterized, the backing pad compounds are dialed in, and the TTV results are predictable.<\/p>\n\n  <p>But the semiconductor industry&#8217;s substrate diversity has expanded far beyond that comfortable baseline. Today&#8217;s production environments routinely combine non-standard wafer diameters (150 mm SiC, 100 mm GaAs, 6-inch compound semiconductor substrates), aggressive slurry chemistries at the pH extremes, older machine platforms with non-catalog carrier head geometries, and increasingly tight TTV and edge flatness targets driven by leading-edge device requirements. In any of these situations, a catalog template becomes a starting point at best and a source of systematic process excursions at worst.<\/p>\n\n  <p>The mismatch typically manifests in one of four ways:<\/p>\n\n  <div class=\"info-grid\">\n    <div class=\"info-card\">\n      <h4>\ud83d\udd27 Geometric Mismatch<\/h4>\n      <ul>\n        <li>Work-hole depth incorrect for target wafer thickness<\/li>\n        <li>Carrier plate OD incompatible with retaining ring ID<\/li>\n        <li>Template thickness outside carrier head pocket range<\/li>\n        <li>Non-standard work-hole count or pattern<\/li>\n      <\/ul>\n    <\/div>\n    <div class=\"info-card\">\n      <h4>\u2697\ufe0f Chemical Incompatibility<\/h4>\n      <ul>\n        <li>FR-4 delamination in acidic SiC slurry environments<\/li>\n        <li>Backing pad swelling with non-standard slurry additives<\/li>\n        <li>Adhesive layer failure under high-temperature CMP<\/li>\n        <li>Fiber contamination from unsealed edges<\/li>\n      <\/ul>\n    <\/div>\n    <div class=\"info-card\">\n      <h4>\ud83d\udcd0 TTV \/ Flatness Failure<\/h4>\n      <ul>\n        <li>Backing pad hardness mismatched to substrate<\/li>\n        <li>Carrier plate bow exceeding process tolerance<\/li>\n        <li>Pressure non-uniformity from non-optimized pad porosity<\/li>\n        <li>Systematic center-to-edge thickness gradient<\/li>\n      <\/ul>\n    <\/div>\n    <div class=\"info-card\">\n      <h4>\ud83d\udccf Edge Profile Failure<\/h4>\n      <ul>\n        <li>Excessive edge rolloff from inadequate edge support<\/li>\n        <li>Edge chipping risk on brittle III-V substrates<\/li>\n        <li>Edge exclusion exceeding device layout requirement<\/li>\n        <li>Asymmetric edge profile from worn catalog template<\/li>\n      <\/ul>\n    <\/div>\n  <\/div>\n\n  <p>In all four cases, a custom-engineered template \u2014 designed from the ground up against your specific carrier head geometry, wafer specification, and slurry chemistry \u2014 is the correct solution.

The three primary carrier plate materials and their custom-application contexts are described below. A detailed head-to-head comparison of their physical and chemical properties is available in our article on <a href=\"https:\/\/jeez-semicon.com\/fr\/blog\/FR-4-vs-G-10-Fiberglass-Polishing-Templates-Material-Properties-Selection-Guide\/\" target=\"_blank\" class=\"text-link-pill\">FR-4 vs G-10 Fiberglass Polishing Templates<\/a>.<\/p>\n\n  <h3>FR-4 in Custom Configurations<\/h3>\n  <p>FR-4 remains the workhorse for custom silicon polishing templates across 100 mm through 300 mm diameters. In custom engineering, FR-4&#8217;s CNC machinability is a significant advantage: complex multi-pocket layouts, precision-milled edge profiles, and tight work-hole depth tolerances are all readily achievable. The critical manufacturing control is edge sealing after machining \u2014 all machined edges on Jizhi FR-4 custom templates receive a mill-and-seal operation under magnified inspection to eliminate any exposed glass fiber that could shed into the polishing environment and cause wafer scratch defects.<\/p>\n\n  <h3>G-10 for Mildly Acidic Custom Applications<\/h3>\n  <p>Custom G-10 templates are specified when the process slurry contains mild acid components (pH 5\u20137) that would cause progressive swelling of FR-4&#8217;s halogenated epoxy matrix over multiple polishing cycles. Typical applications include certain oxide CMP processes using citric acid-buffered colloidal silica slurries, and some specialty glass substrate polishing processes using HNO\u2083-buffered diamond slurry. G-10&#8217;s slightly higher material cost over FR-4 is easily justified by the extended template life in these environments.<\/p>\n\n  <h3>CXT Seamless Grade for Aggressive Chemistry<\/h3>\n  <p>For SiC CMP, GaAs bromine-based polishing, and any process with slurry pH below 5 or above 12, CXT-grade custom templates are the only engineering-sound choice. The seamless single-shell construction eliminates the laminate interface entirely, removing the primary failure mode (epoxy matrix chemical attack at the layer boundary) that limits standard FR-4 and G-10 templates in these environments. Work-hole inner surfaces on CXT templates are machined to the same tolerances as standard grades, and CXT material is compatible with all standard backing pad adhesive systems. For the full application case, see our guide to <a href=\"https:\/\/jeez-semicon.com\/fr\/blog\/SiC-Wafer-Polishing-Templates-Chemically-Resistant-Solutions-for-Silicon-Carbide-Processing\/\" target=\"_blank\" class=\"text-link-pill\">SiC wafer polishing templates<\/a>.<\/p>\n\n  <hr class=\"divider\" \/>\n\n  <!-- \u2550\u2550\u2550 SECTION 5 \u2550\u2550\u2550 -->\n  <h2 id=\"backing-pad\">Backing Pad Engineering: The Hidden Variable in Custom Templates<\/h2>\n\n  <p>Process engineers optimizing for TTV frequently focus on carrier plate geometry \u2014 work-hole depth, plate bow \u2014 while underestimating the backing pad&#8217;s contribution to polishing uniformity. In a well-engineered custom template, the backing pad specification is as carefully determined as any carrier plate dimension.<\/p>\n\n  <p>The backing pad performs three simultaneous mechanical roles during polishing. It acts as a pressure-redistribution layer, evening out localized load concentrations from the carrier head membrane or retaining ring. It provides the capillary-retention force that holds the wafer in the work hole without wax. And it acts as a compliance buffer that allows the wafer to conform slightly to local variations in polishing pad topography, improving contact uniformity at the nanometer scale.<\/p>\n\n  <p>These three roles pull in conflicting directions. High compliance (soft pad) improves pressure redistribution and wafer retention but reduces the pad&#8217;s ability to resist lateral wafer movement under the high shear forces of fast-rotation polishing. Low compliance (hard pad) maintains dimensional precision and resists lateral movement but transmits carrier head non-uniformities more directly to the wafer surface. Custom backing pad engineering for each application finds the optimal point in this trade-off space.<\/p>\n\n  <div class=\"table-wrap\">\n    <table>\n      <thead>\n        <tr>\n          <th>Application<\/th>\n          <th>Backing Pad Hardness<\/th>\n          <th>Pad Thickness<\/th>\n          <th>Key Rationale<\/th>\n        <\/tr>\n      <\/thead>\n      <tbody>\n        <tr>\n          <td>300 mm Si prime SSP (standard)<\/td>\n          <td>Shore A 65\u201375<\/td>\n          <td>0.5\u20130.8 mm<\/td>\n          <td>Balanced compliance for high-volume TTV consistency<\/td>\n        <\/tr>\n        <tr>\n          <td>Ultra-thin Si (&lt; 200 \u00b5m FTT)<\/td>\n          <td>Shore A 35\u201350<\/td>\n          <td>0.6\u20131.0 mm<\/td>\n          <td>Soft pad absorbs carrier head non-uniformities; reduces breakage risk<\/td>\n        <\/tr>\n        <tr>\n          <td>SiC CMP (150 mm)<\/td>\n          <td>Shore A 70\u201385<\/td>\n          <td>0.4\u20130.6 mm<\/td>\n          <td>Hard pad required for high-pressure, long-duration SiC removal cycles<\/td>\n        <\/tr>\n        <tr>\n          <td>GaAs \/ InP compound semiconductor<\/td>\n          <td>Shore A 40\u201355<\/td>\n          <td>0.5\u20130.8 mm<\/td>\n          <td>Soft pad critical for fracture-sensitive III-V substrates<\/td>\n        <\/tr>\n        <tr>\n          <td>CMP device planarization (oxide\/metal)<\/td>\n          <td>Shore A 55\u201365<\/td>\n          <td>0.5\u20130.7 mm<\/td>\n          <td>Medium compliance for planarization efficiency vs. uniformity balance<\/td>\n        <\/tr>\n        <tr>\n          <td>Flip polish \/ edge correction<\/td>\n          <td>Shore A 30\u201345<\/td>\n          <td>0.8\u20131.2 mm<\/td>\n          <td>High compliance to minimize re-polishing pressure at wafer center<\/td>\n        <\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n\n  <hr class=\"divider\" \/>\n\n  <!-- \u2550\u2550\u2550 SECTION 6 \u2550\u2550\u2550 -->\n  <h2 id=\"substrates\">Custom Templates by Substrate Type<\/h2>\n\n  <h3>Silicon (Si) \u2014 High-Volume Custom Variants<\/h3>\n  <p>The most common custom silicon polishing template requests fall into three categories. First, tight-TTV variants for advanced logic and memory applications, where standard catalog templates deliver 1.5\u20132 \u00b5m TTV and the process requires \u2264 0.8 \u00b5m: these require carrier plate bow specifications of \u2264 5 \u00b5m and backing pad thickness uniformity of \u00b1 10 \u00b5m. Second, non-standard diameter silicon templates for R&#038;D and specialty device applications at 150 mm or smaller. Third, multi-pocket high-throughput templates for 100\u2013150 mm substrates, where simultaneous polishing of 5\u20137 wafers per carrier cycle significantly reduces cost-of-ownership.<\/p>\n\n  <h3>Silicon Carbide (SiC) \u2014 The Most Demanding Custom Application<\/h3>\n  <p>Custom SiC polishing templates represent the highest technical complexity in our product portfolio. The combination of extreme substrate hardness (Mohs ~9.5), aggressive oxidant slurry chemistry (KMnO\u2084 at pH 2\u20134), high polishing pressures, and long polishing cycle times creates a uniquely demanding environment. Every SiC custom template from Jizhi uses CXT-grade seamless carrier plate construction, work-hole side-wall liners of chemical-resistant polymer, and backing pad compounds validated for slurry resistance at the process temperature. All SiC templates undergo pre-shipment chemical soak testing to verify dimensional stability after 24-hour exposure to representative SiC slurry. Detailed engineering specifications are covered in our <a href=\"https:\/\/jeez-semicon.com\/fr\/blog\/SiC-Wafer-Polishing-Templates-Chemically-Resistant-Solutions-for-Silicon-Carbide-Processing\/\" target=\"_blank\" class=\"text-link-pill\">Guide du gabarit de polissage SiC<\/a>.<\/p>\n\n  <h3>GaAs, InP &amp; Compound Semiconductors<\/h3>\n  <p>Custom templates for III-V compound semiconductor substrates prioritize fracture-risk mitigation above all other performance metrics. GaAs fracture toughness is approximately one-quarter that of silicon, and a single template-related pressure spike during polishing can crack a wafer worth hundreds of dollars. Custom III-V templates use soft backing pads (Shore A 40\u201355) to maximize compliance, work-hole pocket profiles with generous radius transitions to eliminate stress concentrations at the wafer edge, and reduced-bow carrier plates (\u2264 8 \u00b5m) to prevent localized pressure hot spots.

Glass polishing with colloidal silica at neutral pH is relatively benign for G-10 carrier plates. The primary custom engineering challenge is the wide range of glass substrate thicknesses \u2014 from 100 \u00b5m flexible glass to 2 mm borosilicate \u2014 that require precise work-hole depth specification and backing pad compliance tuning to avoid stress-induced substrate cracking during polishing.

The following practices, drawn from experience across hundreds of custom template qualifications, consistently improve first-pass success rates.<\/p>\n\n  <h3>Provide Existing TTV Baseline Data<\/h3>\n  <p>If you are replacing an existing template (from a different supplier or catalog product), sharing historical TTV and edge profile data from your current template gives our engineers the reference point needed to position the new design for a favorable performance delta from day one. A new design targeting &#8220;better than current&#8221; is far easier to qualify than one targeting an absolute specification with no process history context.<\/p>\n\n  <h3>Run the Qualification at Nominal Process Conditions<\/h3>\n  <p>First-article qualification should be run at your nominal production recipe \u2014 the exact pressure, rotation speed, slurry flow, and polishing time you run in production. Running at modified conditions to &#8220;reduce risk&#8221; changes the mechanical loading on the template and produces TTV and edge profile data that may not predict production performance. If your process has a documented range of recipe variants, run the qualification at the recipe that drives the tightest TTV requirement.<\/p>\n\n  <h3>Measure the Template Before and After Qualification<\/h3>\n  <p>Pre- and post-qualification dimensional measurements of the template (backing pad thickness at four radial positions, carrier plate bow) allow our engineers to correlate template wear rate with polishing cycle count. This data forms the basis of the cycle life recommendation issued with every production design release. It also serves as an early warning if the template is wearing faster than expected \u2014 a potential indicator of slurry chemistry or process pressure issues.

Jizhi engineers custom polishing templates for SiC, GaAs, InP, sapphire, glass, and ceramic substrates.

Qualification orders of 5\u201310 pieces are accepted for initial process development. Production orders are typically placed in quantities of 25\u2013100 pieces per lot to optimize per-unit cost and maintain lot traceability.
