Abstract

A three-dimensional multiple-circuit layer semiconductor device has multiple circuit layers vertically stacked on a single crystal wafer. Thick single-crystal InSb film serves as conductors and contacts, thin single-crystal InSb film serves as semiconductor channels, and CdTe serves as insulator layers. The good lattice match between the two materials permits epitaxial growth of fifty or more layers.
