摘要： A novel image sensor cell structure and method of manufacture. The imaging sensor comprises a substrate, a gate comprising a dielectric layer and gate conductor formed on the dielectric layer, a collection well layer of a first conductivity type formed below a surface of the substrate adjacent a first side of the gate conductor, a pinning layer of a second conductivity type formed atop the collection well at the substrate surface, and a diffusion region of a first conductivity type formed adjacent a second side of the gate conductor, the gate conductor forming a channel region between the collection well layer and the diffusion region. Part of the gate conductor bottom is recessed below the surface of the substrate. Preferably, a portion of the gate conductor is recessed at or below a bottom surface of the pinning layer to a depth such that the collection well intersects the channel region.

摘要： A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region in a semiconductor substrate for accommodation of a first type semiconductor device; forming a second well region in the semiconductor substrate for accommodation of a second type semiconductor device; shielding the first type semiconductor device with a mask; depositing a first metal layer over the second type semiconductor device; performing a first salicide formation on the second type semiconductor device; removing the mask; depositing a second metal layer over the first and second type semiconductor devices; and performing a second salicide formation on the first type semiconductor device. The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different silicide material over different devices.
