GaAs Chip for diagnosing Cancer

GaAs Chip for diagnosing Cancer

Left: Photomicrograph of a 2nd generation 4 x 4 GaAs detector assembly. The device is die attached to the substrate, which in turn is mounted on a 2 stage Peltier cooler.

Right: Photograph of the completed GaAs array/hybrid/substrate assembly. While such an array is too small for space science or medical applications it does allow issues related to pixel performance and inter-pixel communication to be studied. Note any large format device would also use a dedicated ASIC rather than specific components for the electronic readout chain of each pixel.
