Two programs, reduction of thickness of collector alloy and improved collector preform annealing, have been substituted for the programs previously terminated. In addition, an improved method for base assembly storage and a reduction in the thickness of the molybdenum mounting disc have been added as process improvements. The contract device has been changed from the 2N1814 to the 2N2762 transistor. A program of step stress testing has been developed as a method of demonstrating an improvement in the reliability of the contract device. All process improvement and equipment modifications are completed in preparation for the production run.
