When was the first transistor invented?

What was the first transistor?

  • 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-thousandths of an inch thick.

When was transistor created?

  • In 1948, the point-contact transistor was independently invented by German physicists Herbert Mataré and Heinrich Welker while working at the Compagnie des Freins et Signaux, a Westinghouse subsidiary located in Paris.

What is the history of transistor?

  • History of the transistor. A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907.
