TitleLawrence patent notebook (#897)
AuthorLawrence, John E.
Biographical NotesJohn E. Lawrence joined Fairchild circa 1962 as a metallurgical scientist. In this role he provided semiconductor defect analysis, contamination tracking, and other analytical services to the R&D and operating units using a variety of crystallographic and other techniques. During his Fairchild career Lawrence published a minimum of 21 internal R&D Technical Reports (TR) and 7 technical papers in professional journals. On leaving Fairchild circa 1969 he provided similar services to other local companies including the following for which he is named as inventor on patents assigned to them: Silicon Materials Inc. in Mountain View (1974); Winchester Disc, Inc. in Milpitas (1984); EPRI in Palo Alto (1989); Lawrence Technology in Cupertino (1991); and Kobe Precision Inc. in Hayward (1994), all based in California.
ExtentApproximately 3 dated entries over 2 pages.
Dimensions12 x 10 inches
DescriptionThis is the final volume in the 8 volume set of notebooks in the CHM collection written by the author on providing analytical services on silicon wafers to Fairchild R&D personnel and other operating units. All three entries address the topic of “lattice sites as getter centers.”
PatentsThe author is named as inventor on 7 U.S patents. None of these are assigned to Fairchild.
