In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

The idea of an optical transistor — and the associated optical logic circuits that may follow — conjures images of light controlling light in some sparkling, transparent computer. This dream ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

A new type of transistor can dissipate almost zero heat — slashing energy usage in future quantum computers by up to 1,000 times and paving the way for massively scaled-up machines. The ...

A type of 3D FinFET transistor from Intel introduced in 2011 with its Ivy Bridge microarchitecture. The Tri-Gate design is considered 3D because the gate wraps around a raised source-to-drain ...
