The N-well / P-well technology, where n-type diffusion is done over a p-type substrate or p-type diffusion is done over n-type substrate respectively. I guess you are aware of pmos and nmos transistors. I am not a VLSI expert. N-Well Process Step1: Substrate Primarily, start the process with a P-substrate. •The process is single-well (nwell) •CMOS (complementary MOS) uses n- and p-type.
