摘要:
A structure (and method for forming the same) for an image sensor cell. The structure includes (a) a semiconductor substrate; (b) a charge collection well on the substrate, the charge collection well comprising a semiconductor material doped with a first doping polarity; (c) a surface pinning layer on and in direct physical contact with the charge collection well, the surface pinning layer comprising a semiconductor material doped with a second doping polarity opposite to the first doping polarity; and (d) an electrically conducting push electrode being in direct physical contact with the surface pinning layer but not being in direct physical contact with the charge collection well.
