Title: Fred Cumplan: Semiconductor Process Inventor

Introduction

Fred Cumplan is an inventor associated with Pflugerville, Texas, and Motorola Corporation. His patent work addresses semiconductor fabrication, specifically a method for forming a cavity that provides access to deep fuse structures. He is credited with 1 patent in the information provided.

Latest Patents

Cumplan’s listed patent is “Method for Forming a Cavity Capable of Accessing Deep Fuse Structures.” The method uses a staged etching process to create a cavity reaching a structure such as a poly fuse. First, a mask is formed over the structure, and an etch proceeds partway through a first dielectric layer. A second dielectric layer is then deposited, and another mask is used to complete the etch. The final etch passes through the second dielectric layer to an area at or near the target structure. The resulting device retains unetched second dielectric material along the cavity sidewalls.

Career Highlights

The patent reflects Cumplan’s contribution to semiconductor processing techniques for accessing deeply positioned fuse structures. Its layered deposition and etching sequence describes a way to form the cavity while preserving dielectric material on its sidewalls.
