“Transistors, the Microchip & the Second Industrial Revolution”

The first transistor was invented in December 1947. It consisted of a plastic wedge with two gold electrodes, pressed down onto a germanium crystal with a bent paper clip. When the New York Times announced the invention the following year, it received one paragraph on page 48. By the early 1960s it became possible to make dozens of transistors on a single chip of silicon. Even then, few realised they were witnessing the second industrial revolution.
The story of transistors has been characterised by Moore’s law, where the power, speed, cost and size of transistors have undergone a twofold improvement every two years over a 50 year period. Individual transistors are now smaller than viruses, and their price has shrunk from $10 to something like a millionth of a cent apiece.
There are now more transistors in the world than all ants or all leaves on trees. The most recent iPhone has about 15 billion transistors. The average car is said to have about 1,000 microchips. Silicon chips are involved in almost everything we do.
How do transistors and microchips work, and how are they made?

Jim Goding has used transistors and microchips since their first commercial availability in the 1960s. He will tell the story from their humble beginnings, culminating in artificial intelligence systems that are beginning to rival the human brain.


Next talk: Wednesday 19th April  Professor Nicole Bell, University of Melbourne
