diffused transistor การใช้

The post-alloy diffused transistor solved this problem by making the bulk semiconductor crystal the collector ( instead of the base ), which could be as thick as necessary for mechanical strength.
The Philco micro-alloy diffused transistor had a mechanical weakness that ultimately limited their speed; the thin diffused base layer would break if made too thin, but to get high speed it needed to be as thin as possible.
The evolution of technology computer-aided design ( TCAD ) the synergistic combination of process, device and circuit simulation and modeling tools finds its roots in bipolar technology, starting in the late 1960s, and the challenges of junction isolated, double-and triple-diffused transistors.
The "'post-alloy diffused transistor "'( "'PADT "'), or "'post-alloy diffused-base transistor "', was developed by Philips ( but GE and RCA filed for patent and Jacques Pankove of RCA received patent for it ) as an improvement to the germanium alloy-junction transistor, it offered even higher speed.
