The design and development of bipolar junction transistor devices

The data confirm that a decrease in base dimension improves the performance of the bipolar junction transistor. In addition, modifications in design and procedures have improved the quantity and quality of the data collected. The devices produced in this project were functional but not ideal. Nevertheless, this project was able to produce a working BJT device with better performance characteristics than any BJT that has ever been produced in this lab. The designs and methods employed during this project, as well as data collected from this project, will improve the performance quality of future BJT devices produced in this lab.
