Abstract

The performance of Si pyramidal microdischarge photodetectors were characterized in the visible and near-infrared with near-atmospheric Ne plasmas. The inverted pyramid cavities were wet etched into the silicon and were surrounded by a dielectric layer consisting of silicon nitride and polyimide, having a total thickness of ∼ 10 μm. The individual 100×100 μm 2 and 50×50μm 2 devices were tested in a vacuum chamber that was evacuated below 1×10 -6 Torr and backfilled with research grade Ne to a pressure of 500 and 800 Torr. The absolute spectral response of the microdischarge-based photodetectors was also investigated.
