Photodetector device including a photoactive semiconductor over a conductor pattern and method of making the same

Abstract

A technique comprising: forming an insulator over a first conductor pattern; patterning the insulator to form an insulator pattern which exposes the first conductor pattern in one or more via regions; forming a second conductor pattern over the insulator pattern, which second conductor pattern contacts said first conductor pattern in said one or more via regions; creating a more even topographic profile in said one or more via regions, with the second conductor pattern exposed outside the one or more via regions; forming a semiconductor () over the second conductor pattern for charge carrier transfer between the second conductor pattern and the semiconductor; and depositing a third conductor () over the semiconductor, for charge carrier transfer between the third conductor () and the semiconductor ().
