Biographical Notes

Robert K. Waits joined Fairchild circa 1962 and remained with the company until circa 1971. In 1966 he was a Senior Engineer in the Exploratory Devices section of the Physics Department reporting to C. Bittmann. In 1968 he was working in the thin films section. Research into thin film technology for fabricating high value resistors comprised the bulk of his activity during his career with the company.
