Title: Integrated circuit with bipolar and field effect transistors
Inventor: ROKOS GEORGE HEDLEY STORM
IPC: H01L27/118
Filed: 1989-05-05
Abstract: The integrated circuit structure is adapted to provide a desired circuit function having a structure forming an element of any array of similar structures. The structure has a silicon semiconductor p-.type substrate, and an n-.typea epitaxial layer disposed on a major surface of the substrate.  n+.type layer is disposed between the epitaxial layer and the substrate and provides a buried layer below the epitaxial layer. An n+.type sinker extends from the free surface of the epitaxial layer through that layer and provides electrical contact to the buried layer.A region of p-.type material is formed in the free surface of the epitaxial layer and is spaced from the sinker. An insulating layer extends over the free surface of the epitaxial layer and has two openings in register with the p-.type region and the sinker respectively. A layer of polycrystalline silicon is applied to the surface of the structure and contacts the sinker via the opening
