CMP Polishing Pad Brands Comparison: Global Market vs. Domestic Alternatives
An objective comparison of the major CMP polishing pad suppliers — covering product portfolios, specifications, geographic availability, lead times, and the growing case for high-quality domestic alternatives to Western-brand pads in 2026.
Analysis
The CMP polishing pad supply market has historically been dominated by a small number of Western suppliers, with market concentration that left semiconductor manufacturers across Asia exposed to single-source supply risk, long lead times, and pricing dynamics they could not control. The geopolitical events of 2020–2026 have dramatically accelerated the qualification of domestic Asian alternatives — particularly in China, South Korea, and Taiwan — creating a more competitive and resilient supply ecosystem.
This article provides an objective analysis of the major brand landscape, what each supplier’s portfolio covers, and where domestic alternatives like Jizhi Electronic Technology have achieved performance parity or superiority on key metrics. For procurement decision guidance based on specifications rather than brands, see: CMP Polishing Pad Price Factors and Buying Guide.
1. Global CMP Pad Market Landscape (April 2026)
The global CMP polishing pad market is served by five supplier tiers: (1) large, vertically integrated Western CMP consumable companies with full pad and slurry portfolios; (2) specialized Western pad companies; (3) established Asian (primarily Japanese and Korean) CMP materials companies; (4) emerging domestic Chinese suppliers; and (5) specialty suppliers for niche research applications. The market has been shifting meaningfully from tier 1 dominance toward tiers 3 and 4, driven by supply chain risk awareness and government-backed semiconductor materials localization programs across Asia.

3. The Rise of Domestic Asian CMP Pad Alternatives
The 2020–2026 period has fundamentally changed the CMP pad supply landscape in Asia. Supply chain disruptions, US export control risk awareness among fab procurement departments, and government-backed semiconductor supply chain localization programs have driven a dramatic acceleration in the qualification rate for domestically produced CMP pads. As of April 2026, domestically produced pads from Chinese, Korean, and Taiwanese suppliers have achieved production qualifications at wafer fabs across Asia for the following application categories:
- Mature-node oxide and W CMP (28 nm and above): Multiple domestic suppliers fully qualified at leading Chinese memory and logic fabs. Performance parity with IC1000-equivalent pads demonstrated across multiple fab qualification campaigns.
- Cu BEOL soft pads: Qualified at multiple fabs for 28–14 nm Cu CMP steps. Lot-to-lot consistency continues to improve as domestic QC programs mature.
- SiC substrate CMP: Domestic suppliers including Jizhi have achieved customer qualifications at SiC power device substrate manufacturers in China — a segment where Western supply was never well-established due to market newness.
- Advanced node ≤7 nm: Still predominantly Western-supplied. Domestic alternatives are in qualification but require more time to meet the stringent defect density requirements at leading-edge nodes.
4. What to Compare Across Brands During Qualification
Brand name alone is not a useful selection criterion. The following technical criteria should be compared across all shortlisted suppliers — domestic and Western — during pad qualification:
| Criterion | What to Request | Acceptable Threshold |
|---|---|---|
| Hardness uniformity | Shore D 5-point map across pad surface, per lot | Variation <±2 Shore D within lot; lot-to-lot mean variation <±3 Shore D |
| MRR lot-to-lot CV | MRR data from 3+ consecutive lots at reference recipe | CV <5% for porous pads; <3% for poreless pads |
| Pore size distribution | Mean pore diameter and CV (%), optical cross-section analysis | Mean 20–50 µm; CV <18% for hard oxide CMP pads |
| Post-CMP defect data | KLA/Hitachi inspection results on test wafers at target recipe | Meet your fab-specific scratch density and particle count acceptance criteria |
| Documentation package | COA, SDS, batch-specific metrology data, material composition declaration | Full batch-specific documentation per order; no blanket certificates |
| Lead time commitment | Standard and emergency lead time in writing; maximum surge capacity | Standard ≤4 weeks; emergency ≤2 weeks for in-stock items |
5. Supply Chain Resilience: The Strategic Case for Domestic Sourcing
The CMP pad supply disruptions of 2021–2023 exposed the fragility of single-source, single-geography supply for a critical semiconductor consumable. A pad shortage at a wafer fab — where the pad is consumed every 500–2,000 wafers and cannot be substituted without qualification — translates directly to tool downtime and deferred wafer starts. The case for supply chain diversification into domestic alternatives is compelling on risk-management grounds alone, independent of price.
Key resilience advantages of domestic suppliers like Jizhi Electronic Technology versus Western-brand imports:
- Zero cross-border freight, import duty, or export control risk — no dependence on international logistics or US Commerce Department export licensing
- 3–7 day standard lead time versus 8–16 weeks for imported Western pads — dramatically reduced safety stock requirements
- In-person application engineering feasible within 1–2 days — faster problem resolution for process excursions
- Surge capacity accessible on short notice without international logistics coordination delays
- RMB payment — eliminates foreign exchange risk and simplifies accounts payable
6. Jizhi’s Position and Key Differentiators
Jizhi Electronic Technology has built its CMP pad portfolio around three differentiators relative to both Western brands and other domestic suppliers:
In-House R&D and Materials Control
Jizhi formulates its own polyurethane chemistry, controls microsphere selection and loading, and performs in-house DMA, porosimetry, and hardness characterization — enabling genuine co-development with customers rather than catalog selection. For custom applications, see: Custom CMP Polishing Pad Solutions.
Lot-Level Characterization Data as Standard
Every production lot ships with a batch-specific COA including Shore D 5-point map, pore size distribution histogram, baseline MRR at reference recipe, and groove profilometry. This lot-level data enables APC integration and eliminates the need for full in-house characterization of each new lot — a capability that Jizhi provides as standard, not as a paid premium.
SiC Pad Capability — Domestic Pioneer
Jizhi is among the few domestic suppliers with production-qualified SiC-specific CMP pad series (JZ-SiC-I and JZ-SiC-II) for Stage 2 and Stage 3 SiC substrate polishing. This segment has historically had very limited Western supply, making Jizhi’s domestic availability uniquely valuable for China’s rapidly expanding SiC power device industry.
Full Product Range — Hard, Soft, SiC, Poreless
Jizhi supplies hard oxide pads (JZ-H60, JZ-H65), soft Cu BEOL subpads (JZ-S28, JZ-S38), SiC-specific pads (JZ-SiC-I, JZ-SiC-II), and a poreless series currently in customer qualification — covering the full pad type spectrum from a single qualified supplier relationship.
