TitleSklar patent notebook (#425)
Biographical NotesMaija Sklar was the first female engineer to be hired by Fairchild. She worked for Bruce Deal at Raytheon Semiconductor in Mountain View and followed him to Fairchild in 1963. She handled his experimental process runs primarily focused on understanding issues related to oxidation and its role in MOS instability and surface states. A 1966 organization chart shows Sklar as an Engineer A in the Surfaces-Device Theory section led by A. Grove that reported to C. Bittmann, head of the Solid State Physics Department. This section that included B. Deal, E. Snow, and R. Whittier resolved many of the fundamental technological issues associated with stable, commercial MOS devices. Her work was an important contributor to the 1967 paper “Characteristics of the surface-state charge (Qss) of thermally oxidized silicon” with Deal, Grove and Snow that is the fifth most frequently cited paper in the history of the Electrochemical Society. She retired from Fairchild in 1986.

DescriptionThis volume contains detailed records of process runs managed by the author for Bruce Deal. Material type and processing steps are documented for runs designated BED-416 through BED-827. During this period Deal was working with Andy Grove and Ed Snow investigating the sources of MOS instability and surface state conditions. Several runs (1965-11-01, 1966-02-28, and 1966-03-01) were identified as for “Na analysis.” Technical Reports based on this work that were published during the period covered by this volume include TR211, and TR261. The latter was the first report to unequivocally characterize surface state charge in the Si-SiO2 system, and describe detailed processing approaches to control and minimize this charge and a 1967 conference paper (below) of the same name includes Sklar as an author.
