Why semiconductor fabs use PEEK (not POM) for wafer carrier components, and how to machine without contamination.
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.
