TitleCastro patent notebook (#625)
DescriptionThis volume contains weekly memos written by Castro on the status and support work involved in transferring the Philips, Holland CMOS process to Fairchild. Following her resignation in 1973-05, the reports are continued by T. Kamins. The reports include personnel responsibilities, equipment requirements, mask and process specifications and complexities involved in establishing a process developed with different equipment, in a different corporate and social environment. Castro’s resignation is noted on page 64. A plan to introduce the first products in 1973-11 is noted on page 115. Kamins’ important contribution to the task is noted by B. Deal on page 149.
AuthorCastro, P. (Pat) L.
Biographical NotesP. (Pat) L. Castro worked at Fairchild from circa 1966 to 1973. A 1968 organization chart shows her in the Contact Technology section of the Materials and Processes Department reporting to I. Blech. Most of the work described in these volumes and the resulting publications was performed under the supervision of B. Deal who at that time was Section head of Dielectric Films. From 1972-11 until her resignation in 1973-05, Castro documented to work of an R&D team working together with Mountain View production personnel in transferring a Philips CMOS process to Fairchild.
