Hybrids semiconductor circuit

Abstract

A hybrid semiconductor device which comprises a semiconductor substrate having electrical devices therein with a plurality of spaced apart relatively rigid standoffs of electrically insulating material disposed over the substrate. Each of the standoffs has a substantially planar exposed surface remote from the substrate. A first layer of electrically insulating material more resilient than the standoffs is disposed over the substrate and between the standoffs and has an upper surface coplanar with the planar exposed surfaces of the standoffs. A semiconductor superstrate is secured to the first layer of electrically insulating material, the superstrate containing electrical devices. A connection connects the electrical devices contained in the superstrate to the electrical devices in the substrate.
