WebThe p-Well CMOS fabrication Process. In this process of CMOS, the structure consists of an n-type substrate in which p-type devices may be formed by suitable masking and diffusion. In order to accommodate n-type devices, a deep p-well is diffused into the n-type substrate as shown in the figure below. CMOS p-well process steps. Webarsenic dose was used together with the regular n-well implant anda flatplateauofdeep n-well.Thepostimplantannealing was performed at 1000 C. As a result, the resultant n-well (i.e., reg-ular n-well and deep n-well combined) completely surrounds the p-well region for junction isolation. The resultant p-well and deep n-well depth are about 0.8 m ...
