Biographical Notes

Maurice E. Dumesnil worked for DuPont, located in Wilmington, Delaware, in 1960. He joined Fairchild circa 1961 where he performed research on deposition of oxide on silicon and on glass materials used in the sealing of semiconductor device packages. In 1966 he was a Member Technical Staff in the Materials and Processes Department reporting to H. Sello and in 1968 he was in the Dielectric Films section reporting to B. Deal. He joined Technology Glass Corporation, Sunnyvale, California, in the 1970s and in the late 1980s was with VLSI Packaging Materials, Inc. Sunnyvale, California.

Description

This volume describes processes and procedures followed in the exploration of deposited materials, especially as related to improved packages. Many wafers are taped onto the pages. Specific entries include; selenide glass films in tunnel diodes (p. 6); hermetic passivation with glass films (p. 8); evaporation of silver-chromium-gold films (pp. 14-16); design of a solid-sate adaptive component (pp. 48-50); thin film resistor connections (p. 70); search for low expansion soft glass (p. 82); thoughts on face-down alignment of FEBs on passive substrates (pp. 90-91); status of scratch resistant Al films (p. 131).

This is one of 3 volumes issued to the author. The other volumes are Dumesnil (370) and (1117).
