Title: The Innovations of Donald L Hornback

Introduction

Donald L Hornback is a notable inventor based in Kokomo, Indiana. He has made significant contributions to the field of integrated circuits, particularly in the development of pressure-sensitive technologies. With a total of 2 patents to his name, Hornback's work has had a lasting impact on the industry.

Latest Patents

Hornback's latest patent is a monolithic pressure-sensitive integrated circuit. This innovative circuit is created by first providing a localized etch-stop layer on one surface of the silicon chip. Successive epitaxial layers of opposite conductivity types are then grown over this surface. In the upper layer, a bridge of four piezoresistors is formed, which overlays the periphery of the etch-stop layer. The conditioning circuitry amplifies the output of the bridge and includes both lateral and vertical junction transistors. The back surface of the chip is etched anisotropically to create a cavity, leaving a thin diaphragm that underlies the bridge of the four piezoresistors.
