Abstract
Disclosed is an integrated circuit having at least two active components, such as transistors, having the following features: a highly conductive substrate is provided which is connected to one pole of a voltage supply source, a semiconductor layer, which is electrically isolated from the substrate and divided into individual sections by lateral isolation regions, is disposed on a main surface of the substrate, placed in each section is at least one active component, e.g., a transistor of any type performance, and lateral deep diffusion regions which are accommodated in the semiconductor layer create a conductive connection between the highly conductive substrate and the corresponding regions of the active components.
Claims23
An integrated circuit having at least two active components constituted by semiconductor elements and being characterized by:
- a highly conductive substrate which is connected to one pole of a voltage supply source;
- a semiconductor layer provided on a main surface of said substrate in a manner in which said semiconductor layer is electrically isolated from said substrate and is disposed as plural semiconductor layer sections, said semiconductor layer sections being respectively isolated from each other by providing isolation regions therebetween;
- providing in each semiconductor layer section at least one transistor as an active component thereof;
- and
- lateral deep diffusion regions provided in said semiconductor layer each of said lateral deep diffusion regions being disposed so as to effect locally a direct electrical connection between said highly conductive substrate and a corresponding active region of individual ones of said active components.
