John Pierce coined the name of this invention, which began as strips of gold attached to a plastic triangle called the "point-contact" type.

This device, which replaced Lee De Forest's triode tube, was easier to manufacture in the "bipolar junction" form than the "field effect" form. Every 18 months, the number of these which can fit on an IC doubles, according to Moore's Law. Bell Labs scientists Brattain, Bardeen, and Shockley won the 1956 Nobel for inventing this device. For 10 points, name these semiconductor-containing devices used as amplifiers and switches.
