This gave rise to the popular TTL (Transistor-Transistor Logic) series of logic chips, which were constructed using bipolar transistors. It was made using primitive dual three-input NOR gate ICs, which consisted of merely 3 transistors per gate. Eleven years later, Apollo 11 landed on the Moon, thanks to the revolutionary Apollo Guidance Computer, which was the world’s first embedded computer. Then in 1958, Jack Kilby came up with the first integrated circuit which put more than one transistor on the same die. First came the invention of the first bipolar transistor in the following year. However, bipolar transistors were quicker to catch on commercially, with the first chip made of bipolar transistors appearing in the 1960s, with MOSFET manufacturing technology being perfected in the 1980s and soon overtaking their bipolar cousins.Īfter the point contact transistor was invented in 1947, things began to move quickly. It might be surprising to know that the patent for a ‘field effect transistor’ predated the creation of the bipolar transistor by at least twenty years. ![]()
