Artifact Details


Allison patent notebook (#153)

Catalog Number







Allison, David F.

Biographical Notes

David (Dave) F. Allison was an employee of Shockley Semiconductor prior to joining Fairchild in 1957 when he was issued company patent notebook # 10. He worked initially on the first NPN transistor project as a process engineer responsible for the development of diffusion techniques. He was a member of the Device Development Group at R&D when he resigned to join the founding group at Signetics in August 1961. In 1971 he was with Signetics Memory Systems. In an oral history, Lionel Kattner credited Allison with contributing to his understanding of process technology that played an important role in the development of diffusion techniques used in the electrical isolation of Micrologic devices in the period of 1960 covered by this book. CHM has a photo of Allison in the collection. See Accession Number: 102708135.
