An insulating layer on the surface of a slab of photo-responsive semicondor material is treated to produce a pattern of projections or mesas. The treatment includes the steps of producing a mask on the insulating layer using electron-beam lithography, etching holes in the layer through the mask, stripping the mask, and finishing with the usual electrical conductors on the insulating layer. An alternate embodiment etches the surface of the slab to produce a scrabrous surface, then coats with aluminum oxide and electrical conductors.

Method of making semiconductor photodetector with reduced time-constant

A two-dimensional array of small, thin, flexible, metalized mirrors are mted atop supports on one side of a photoelectric layer. A visible light or infrared image on the other side of the layer induces an electron image (charge pattern) beneath the mirrors. The mirrors deflect towards the layer in accordance with the charge pattern. Light projected onto the mirrors is reflected and forms an image dependent on the deflections thereof.
