  • Asymmetrically positioned guard ring contacts
    Patent number: 11251214
    Abstract: According to an embodiment, a device comprises a direct conversion compound semiconductor layer configured to convert high energy radiation photons into an electric current, the direct conversion compound semiconductor layer comprising: a pixel array positioned in the direct conversion compound semiconductor layer, including pixels located at an outermost circumference, wherein the pixels comprise signal pads; a guard ring encircling the pixel array, wherein the pixels at the outermost circumference are closest to the guard ring; guard ring contact pads, wherein the guard ring contact pads are situated in place of some of the pixel signal pads at the outermost circumference and connected to the guard ring; wherein the guard ring contact pads are further situated asymmetrically with respect to a symmetry x-axis and a symmetry y-axis of the direct conversion compound semiconductor layer.
