Abstract:
In order to form a light receiving element having high reliability and a MOS transistor together on the same silicon substrate, after forming a gate electrode of the MOS transistor, a gate oxide film in a light receiving element forming region is removed. Then, a thermal oxide film is newly formed in the light receiving element forming region, and ion implantation is performed in the light receiving element forming region through the thermal oxide film such that a shallow pn junction is formed.

Claim (Index 5):
A method of manufacturing a semiconductor device according to  claim 1 , further comprising:\n forming a first insulating film on the second thermal oxide film; forming a second insulating film on the first insulating film; and performing anisotropic etching by using the first insulating film as an etching stopper, to thereby form a side wall comprising the second insulating film on a side surface of the gate electrode of the MOS transistor.
