Patent ID: 7683414

Claim:
A semiconductor image pickup device having a first region including a silicide layer and a second region without a silicide layer being formed, wherein a sidewall comprised of a plurality of insulating films which includes a first and second insulating layer formed at a side of a gate electrode of a first field effect transistor formed in said first region, the first and second insulating layers located in the first region only being formed at sidewalls of gate electrodes and said silicide layer is also formed at a source/drain region of said first field effect transistor, and said second region includes a second field effect transistor covered by said first insulating layer, said second field effect transistor having a sidewall further comprised of said second insulating layer of said plurality of insulating films formed corresponding to a side of a gate electrode of said second field effect transistor, wherein at least one insulating layer formed at a sidewall of the second field effect transistor is only located at sidewalls of gate electrodes in the second region.
