Abstract:
1. An active pixel comprising: a photosensor formed in a semiconductor substrate; a transfer transistor formed between said photosensor and a floating node and selectively operative to transfer a signal from said photosensor to said floating node; an amplification transistor controlled by said floating node, said amplification transistor having an amplification gate and a diffusion region; a local interconnect structure electrically connecting said floating node to said amplification gate, said local interconnect structure being formed at least partially on top of said amplification gate and at least partially conforming to a sidewall of said amplification gate; and a patterned insulator layer formed between said local interconnect structure and said diffusion region of the amplification transistor and at least partially conforming to the sidewall of the amplification gate, the patterned insulator layer to electrically isolate said local interconnect structure from said diffusion region.
