Silicon carbide sand production equipment manufacturer

Transistor - Wikipedia

The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz. These were made by etching depressions into an N-type germanium base from both sides with jets of Indium(III) sulfate until it was a few ten-thouhs of an inch thick. Indium electroplated into the depressions formed the collector and emitter.
