drift transistor การใช้

The 7090 used the Standard Modular System ( SMS ) cards using current-mode logic some using diffused junction drift transistors.
This graded base happens automatically with the double diffused planar transistor ( so they aren't usually called drift transistors ).
Early drift transistors were made by diffusing the base dopant in a way that caused a higher doping concentration near the emitter reducing towards the collector.
Kroemer was elected as a member of the National Academy of Engineering in 1997 and the drift transistor and was the first to point out that advantages could be gained in various semiconductor devices by incorporating heterojunctions.
