2026-05-23Choosing p type silicon wafers usually starts with the device structure, not only the wafer price. P type silicon uses acceptor doping, most commonly boron, so holes become the main charge carriers. This electrical behavior makes it suitable for many mature semiconductor processes, MEMS structures, sensors, solar cells, test wafers, and research devices.
