The invention of the transistor
In the period immediately following the Second World War, there was a major step forward in electronics brought about by the invention of the first working transistor. In 1948, Shockley, Barden and Brattain, working in the Bell Telephone Laboratories in the USA, demonstrated that a transistor could amplify electrical signals and act like a switch. However, the way electricity moved in semiconductors, as these germanium-based devices were called, was not well understood. Furthermore, until the 1950s it was not possible to produce germanium with the high purity required to make useful transistors.

These transistors turned out to be successful rivals to the thermionic valve. They were cheaper to make since their manufacture could be automated. They were smaller, more rugged and had a longer life than valves, and they required less electrical power to work. Once silicon began to replace germanium as the basic semiconductor for making transistors in the 1960s, it was clear that the valve could never compete with the transistor for reliability, compactness and low power consumption.


The computer was built in the 1940s at the University of Pennsylvania. ENIAC (Electronic Numerical Integrator and Calculator) filled a room, used 18000 valves, needed 200 kW of electrical power to work it, had a mass of 30 tons and cost a million dollars. The first transistorized desktop calculator of the 1960s was battery-powered, had a mass of a few kilograms and was capable of far more sophisticated calculations than ENIAC was able to perform. This trend towards low-cost yet more complex functions, to greater reliability and lower power consumption continues to be an important characteristic of developments in electronics. ENIAC is now regarded as a first-generation computer and the transistorized computers that followed it in the 1960s as second-generation computers. Third–generation computers required the development of the silicon chip.
Silicon chips make an impact
The first integrated circuits were made during the early 1960s. Techniques were developed for forming up to a few hundred transistors on a silicon chip and linking them together to produce a working circuit. The Apollo spacecraft that took men to the Moon in the late 1960s used these third-generation computers for navigation and control. The stimulus to miniaturize circuits in the form of integrated circuits came from three main areas: weapons technology, the “space race” and commercial activity.

Modern weapons systems depend on circuits that are small, light, quick to respond, reliable, and that use hardly any electrical power. Miniature circuits on silicon chips play a great role in the “space race” when Americans walked on the Moon by the end of the decade. Lacking the enormously powerful booster rockets developed by Russia, America needed compact and complex spacecraft and stimulated the design of small and reliable control, communications and computer equipment. During the 1970s, spin-off from military interests and the space race further stimulated the growth of an electronics industry bent first on creating electronics goods and then satisfying the demand for them at home, in the office and industry.

The 1970s saw the number of transistors integrated on a silicon chip. The most important silicon chip is the microprocessor. It contains most of the components needed to operate as the central processing unit (CPU) of a computer. A highly complex device that can be programmed to do a variety of tasks acts as the “brain” in a wide variety of devices. These forth-generation computers have become faster and cheaper; they are now used in industrial robots and sewing machines, in space stations and toasters, in medical equipment and computer games. Their programmability and cheapness are their strength. The microprocessor brings the story to the present day.
