A multi-wavelength semiconductor image sensor comprises a p-type Hg0.7Cd0.3Te photo-absorbing layer formed on a single crystal CdZnTe substrate, a CdTe isolation layer deposited on the photo-absorbing layer, a p-type Hg0.7Cd0.23Te photo-absorbing layer deposited on the CdTe isolation layer, n+ regions which are formed in these photo-absorbing layers and form a pn-junction with each of these photo-absorbing layers, an indium electrode connected to each of these n+ regions and a ground electrode connected to the photo-absorbing layer, the semiconductor isolation layer being electrically isolated from the photo-absorbing layer.
