Abstract:
A method for fabricating an image sensor array having a first group of photodiodes for detecting light at visible wavelengths a second group of photodiodes for detecting light at infrared or near-infrared wavelengths, the method including forming a germanium-silicon layer for the second group of photodiodes on a first semiconductor donor wafer; defining a first interconnect layer on the germanium-silicon layer; defining integrated circuitry for controlling pixels of the image sensor array on a semiconductor carrier wafer; defining a second interconnect layer on the semiconductor carrier wafer; bonding the first interconnect layer with the second interconnect layer; defining the pixels of an image sensor array on a second semiconductor donor wafer; defining a third interconnect layer on the image sensor array; and bonding the third interconnect layer with the germanium-silicon layer.

Claim (Index 2):
A method for fabricating an image sensor array having a first group of photodiodes for detecting light at visible wavelengths formed from a first material, and a second group of photodiodes for detecting light at infrared or near-infrared wavelengths formed from a second material different than the first material, the method comprising:\n forming the first group of photodiodes on a semiconductor donor wafer; forming the second group of photodiodes on the semiconductor donor wafer, comprising:\n forming, on the semiconductor donor wafer, one or more recesses for the second group of photodiodes; and \n growing a germanium-silicon layer on the one or more recesses for the second group of photodiodes; \n after growing the germanium-silicon layer, defining a first interconnect layer, wherein the first interconnect layer includes a plurality of interconnects coupled to the first group of photodiodes and the second group of photodiodes; defining integrated circuitry for controlling the first group of photodiodes and the second groups of photodiodes on a semiconductor carrier wafer; after defining the integrated circuitry, defining a second interconnect layer on the semiconductor carrier wafer, wherein the second interconnect layer includes a plurality of interconnects coupled to the integrated circuitry; and bonding the first interconnect layer with the second interconnect layer, such that the first group of photodiodes and the second group of photodiodes are coupled to the integrated circuitry.
