TitleBarry patent notebook (#1275)
AuthorBarry, Michael L.
Biographical NotesMichael (Mike) L. Barry served as a Member of Technical Staff in the Material and Processes Department of the R & D Lab from circa 1965 to circa 1987. A 1968 organization chart shows him in the Silicon Processes section reporting to W. Shepherd. His major research activity over this period was related to the chemical vapor deposition (CVD) of oxide to produce a material commonly known as Vapox and the specific applications of phosphovapox. During his Fairchild career Barry was named as inventor on at least one U.S. Patent, and published a minimum of 10 internal R&D Technical Reports (TR) and 5 technical papers in professional journals.
ExtentIndex (p. 1) lists entries about 28 wafer runs identified by run number and date.
Dimensions12 x 10 inches
DescriptionThis volume continues the style of earlier Barry notebooks in recording the results of experiments on the processing and applications of Vapox, chemical vapor deposited silicon oxide, including Polaroid microphotographs of silicon surfaces and copies of run summary sheets pasted onto the pages. In addition to information on wafer runs this volume includes a number of invention disclosures; chip protection by aluminum anodization (p. 5); manufacturing of capacitors in linear ICs (p. 35); improved characteristics of MNOS memory devices (p. 29); beam leads using polysilicon-gold leads (p. 41); polysilicon deposition (p. 51). Pages 51–83 contain colored photographs of four AMS and Motorola ICs provided by patent attorney Roger Borovoy for analysis of the passivation processes.
