Title: Manufacture of solid state image pickup
Inventor: MATSUMOTO KAZUYA
IPC: H01L21/8238
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate alignment deviation of selective oxide film forming regions by forming first selective oxide films on first and second regions, then forming a film having oxidation resistance only on the first region, and then secondly selectively oxidizing to form selective oxide films having different thicknesses. CONSTITUTION:A pad oxide film 2 is formed on a semiconductor substrate 1. Then, after a first Si3N4 film 3 is formed, photolithographies for opening a selective oxide film forming region of a CMOSFET for constituting a peripheral scanner, etc., and a selective oxide film forming region used to form a drain diffused layer of a CMD photodetector are commonly conducted simultaneously, thereby forming resist patterns 4. The step is employed to eliminate alignment deviation of the selective oxide film of the first region formed of the CMD photodetector and the selective oxide film of the second region formed of a CMOSFET for scanning the photodetector. Thus, the cost of yield due to pattern alignment deviation is largely improved.
