Semiconductor Wafer Carrier — PEEK Machined

Why PEEK in Wafer Handling

Semiconductor wet bench environments combine 80 °C+ chemistries (HF, KOH, hot DI water) with the strictest particulate cleanliness. POM, PEEK, and PFA are the three polymers that survive this regime. POM is cheaper but degrades over months of exposure. PFA is chemically perfect but soft. PEEK splits the difference: chemical resistance approaching PFA, mechanical strength approaching aluminum.

Specification We Supply

• Material: 100% virgin PEEK natural beige (no carbon black — eliminates particle generation source)
• Form: Rod 50 – 150 mm diameter × 1 m, machined to drawing
• Tolerance: ±0.025 mm on critical wafer-contact surfaces
• Surface finish: Ra 0.4 µm typical on machined surfaces (lower on request)
• Cleanliness: IPA wash + double bag for cleanroom handling

Common Carrier Types

Single-wafer carriers, cassette holders, robot end-effector mounts, wet bench drying brackets. We've supplied parts for 200 mm and 300 mm wafer fabs.

Lead Time

Prototype 14 – 18 days. Production volume 25 – 35 days FOB Qingdao.
