Abstract:

As of April 30, 1963, of the 17 active process and equipment programs, 8 are completed and in production use, 6 are installed and undergoing production trials, 1 is currently being installed and 2 are in process development stages. Failure rates of Milestone II test were included in the previous report and graphs of the parameter distributions are included in this report. Pre liminary information from Milestone III trans istors is reported and the status of Milestone IV transistors construction is reviewed. Also, additional manufacturing test results and special accelerated test results are reported. The failure analysis program has continued to yield information as to the nature of failures and provides a quantitative measurement of the various failure modes. The analytical-empirical surface study programs have provided additional experi mental results. Actions now under way for pro duction changes are based upon some of these results. Additional electron probe work has presented dramatic pictorial evidence and sug gests new approaches for future study of the sources, effects, and elimination of surface materials. Author
