Anti-Static / ESD-Safe PP Wafer Cassettes
Cost-effective ESD-safe polypropylene cassettes with static-dissipative to conductive resistivity grades for cleanroom transport and storage.
Overview
Electrostatic discharge is a leading cause of device damage in advanced semiconductor manufacturing, particularly for gate oxides thinner than 2nm at advanced logic nodes. GINECHIP's anti-static and ESD-safe polypropylene cassettes use conductive carbon loading or anti-static additives to control charge buildup across three protection tiers: static-dissipative (10⁶–10⁹ Ω/sq) for controlled, gradual charge bleed-off; conductive (below 10⁴ Ω/sq) for rapid dissipation protecting the most sensitive devices; and topical anti-static treatments for general-purpose, cost-sensitive applications.
Beyond ESD performance, these cassettes are significantly lighter than metal alternatives, reducing wear on automated material handling systems (AMHS) and operator fatigue during manual handling. Available with customizable resistivity, black or process-identification colors, and slot configurations from 13 to 50 wafers across 150mm–300mm diameters.

Applications
Interbay and intrabay AMHS transport and stocker storage, where lightweight ESD-safe PP reduces automation wear compared to metal or PEEK alternatives.
CD-SEM, defect review, and film thickness measurement stations where low-outgassing, particle-controlled ESD-safe cassettes protect metrology chamber cleanliness.
Day-to-day wafer handling in Class 100 / ISO 5 and above cleanroom environments where cost-effective ESD protection is required without extreme chemical or thermal demands.
Conductive-grade cassettes (below 10⁴ Ω/sq) for advanced CMOS devices with sub-2nm gate oxides that cannot tolerate any uncontrolled static discharge.
Quality & Certification
All ESD-safe PP cassettes are manufactured under ISO 9001:2015 certified quality management, with ESD performance validated per ANSI/ESD S20.20 and static decay tested per MIL-B-81705C. Surface resistivity is verified on every production lot, with test data available on request.
