Spacistor
The spacistor〔
〕 was a type of transistor developed in the 1950s as an improvement over the point-contact transistor and the later alloy junction transistor. It offered much higher speed than earlier transistors.
It is composed of a P-N junction with a wide depletion region, inside which two additional contacts are made: the ''injector'' and the ''modulator''. The P material was called the ''base'' and the N material was called the ''collector''. The ''injector'' acted like a BJT (bipolar junction transistor) emitter, the ''modulator'' like a base, and the ''collector'' like its BJT namesake. It achieved high speed by reducing the charge carrier's transit time. It became obsolete in the early 1960s with the development of the diffusion transistor.
