The Transistor In A Century Of Electronics

A Three Terminal Device

A transistor mounted on a metal can with three wires to each of the three terminals.

Light Bulbs and Vacuum Tubes

Vacuum tubes were made containing several three terminal devices called triodes.

Lee De Forest and The Radio

Radio brought information rapidly to the masses and was the first widely used electronic device in the home.

Early Computers

The largest computers based on vacuum tubes had racks and racks of tubes filling large rooms.

The First Transistor

The first point contact transistor made use of the semiconductor germanium. Paper clips and razor blades were used to make the device.

Limits of Individual Transistors

Individual electronic components were soldered on to printed circuit boards.

The Integrated Circuit

Integrated circuits placed all components in one chip, drastically reducing the size of the circuit and its components.
