Abstract

See full text

The present invention is a front-side contact, back-side illuminated (FSC-BSL) photodiode arrays and front-side illuminated, back-side contact (FSL-BSC) photodiode arrays having improved characteristics, including high production throughput, low-cost manufacturing via implementation of batch processing techniques; uniform, as well as high, photocurrent density owing to presence of a large continuous homogeneous, heavily doped layer; and back to front intrachip connections via the homogenous, heavily doped layers on the front and back sides of the substrate.
