Paper Abstract

The CVORG group at the University of Delaware is responsible for designing and developing a test platform for the operation and characterization of a 512×512 array of infrared LED emitters. This platform consists mainly of an integrated circuit responsible for driving current to the LEDs, a package to which the driver and LEDs can be mounted, and a cryogenic dewar used to run tests at 77K. The fabrication of the driver read-in integrated circuit, or RIIC, was completed using a 0.5μm CMOS process from OnSemiconductor. Because of the size of the array, stitching techniques were used to create the 3.3cm×3.3cm chip. The cryogenic package is a custom 6-layer printed circuit board (PCB) plated in a soft wire-bondable gold. Finally, modifications were made to the cryogenic dewar to allow us to properly interface with the RIIC.
