    [30]: 153 [31]: 145 Shive's invention sparked [32] Shockley's invention of the junction transistor. [30]: 143 A few months later he invented an entirely new, considerably more robust, type of transistor with a layer or 'sandwich' structure. This structure went on to be used for the vast majority of all transistors into the 1960s, and evolved ...

    The first practical transistor was the point-contact transistor, invented by the engineers Walter Houser Brattain and John Bardeen while working for William Shockley at Bell Labs in 1947. This was a breakthrough that laid the foundations for modern technology. [2] Shockley's research team also invented the bipolar junction transistor in 1952.
