Patent ID: 7915652

Claim:
An integrated infrared (IR) and full color complementary metal oxide semiconductor (CMOS) imager array comprising: a lightly doped p doped silicon (Si) substrate; a plurality of pixel cells, each pixel cell including: at least one visible light detection pixels, each pixel including a moderately p doped bowl with a bottom p doped layer and p doped sidewalls, an n doped layer enclosed by the p doped bowl, a moderately p doped surface region overlying the n doped layer, and a transfer transistor with a gate electrode overlying the p doped sidewalls, a source formed from the n doped layer, and an n+ doped drain connected to a floating diffusion region; an IR pixel including moderately p doped sidewalls, an n doped layer enclosed by the p doped sidewalls, a lightly p doped layer of p doped substrate underlying the n doped layer, a moderately p doped surface region overlying the n doped layer, and a transfer transistor with a gate electrode overlying the p doped sidewalls, a source formed from the n doped layer, and an n+ doped drain connected to the floating diffusion region; and, an optical wavelength filter overlying the visible light and IR pixels.
