Abstract

The current development of UV-Blue sensitive photo-detectors has lead to investigations with the polywell-stacked gradient poly-homojunction (StaG) configuration. Backwall illumination is of interest due to increased fill factor and pixel wavelength band tailoring. The StaG architecture has benefits. However, for benefit to backwall illumination the space charge region needs to be depleted to the backwall, possibly dispensing with the need for the StaG multi-layer. This research is an initial investigation of the benefit to crosstalk and sensitivity of the deep single well in high resolution, 5 μm pitch, photodiode arrays. The results indicate that geometries that are of fabricatable morphology can benefit backwall illumination especially in the U/V-blue wavelength spectrum.
