Manufacturing Methods and Technology (MM and T) measure for fabrication of silicon transcalent thyristor

This fifth quarterly report describes the progress on the MM and TE program for Transcalent (Heat-Pipe cooled) thyristors. Production engineering measures for the device and the pertinent state-of-the-art on the sample devices are included. Initial test results on the first confirmatory samples are listed. The present status includes the submission of the Test Plan for the confirmatory samples, the fabrication of the confirmatory sample devices, the engineering analyses of the initial test results on these devices, and the equipment refinements being procured for this program. Plans for the next quarter include the conclusion of the confirmatory sample phase, the preparation of the test report for these confirmatory samples, as well as the preparations for the pilot run phase.
