It worked on the known semiconductors of the time: copper oxide and selenium and developed a selenium diode that went into production at the Electron Tubes product division. Philips had formed a dedicated solid state physics group within NatLab in the 1930s. Physics (vacuum tubes and microscopy) directed by CasimirĬhemistry (materials, semiconductors and transistors) directed by E VerweijĮngineering (applications) directed by Rinia In the 1950s Natlab was comprised of three sections each with a Director: This is where the history of Philips’ semiconductor developments begins. Later it branched out into consumer electrical and electronic products.įrom 1914 its research and development was carried out at the Eindhoven Natuurkundig Laboratorium usually abbreviated to Natlab. The company quickly became a major European tube and radio receiver manufacturer.
Early on its products included incandescent bulbs which led it to begin producing vacuum tubes initially under contract in 1917 and then in its own name from 1919. Phiilips was founded in 1891 by Gerard Philips in Eindhoven, the Netherlands. When this happened it would revolutionize the design of computers.History of Philips’ Semiconductors in the 1950s A little later, however, the integrated circuit would be mass-produced (largely to meet the needs of NASA’s Apollo program and the United States’ missile programs). Integrated circuits were so expensive that the first ones were purchased only by the military, which could justify the cost for top-notch performance. But the idea of fabricating an entire circuit on a silicon wafer or “chip” with one process was a real breakthrough. The first integrated circuits (ICs) were very simple and merely demonstrated the concept. Two engineers, Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor, invented such circuits-called integrated circuits-in 1958. Dummer proposed the idea of making the entire circuit directly on a silicon wafer, instead of assembling the circuits from individual transistors and other components.
There were many proposals for doing this, but British engineer G. Engineers reasoned that standard circuits should be designed as units, in order to make them more compact. The packaged, individual transistors were then wired into circuits along with other components such as resistors and capacitors.Īs computers were produced in larger numbers, some kinds of logic circuits became fairly standardized. These were cut up into individual pieces and mounted inside a package for easier handling and assembly. By the 1970s, mass-production techniques allowed nearly microscopic transistors to be produced by the thousands on round silicon wafers. Researchers found that making transistors switch faster required that the transistors themselves be smaller and smaller, because of the way electrons move around in semiconductors-if there is less material to move through, the electrons can move faster. The speed at which a computer can perform calculations depends heavily on the speed at which transistors can switch from “on” to “off.” In other words, the faster the transistors, the faster the computer. Unlike the earlier electron tubes (often called vacuum tubes), transistors allowed the design of much smaller, more reliable computers-they also addressed the seemingly insatiable need for speed. Thousands and later tens of thousands of these switches were needed to make up the complicated logic circuits that allowed computers to compute. In a computer the transistor is usually used as a switch rather than an amplifier. But, nice as a hand-held radio is, the real transistor revolution was taking place in the field of computers. The transistor radio revolutionized the way people listened to music, because it made radios smaller and portable. If you ask someone who lived during the late 1950s or 1960s what they associated with the transistor, there is a good chance they’ll say “transistor radio.” And with good reason. This device, developed by Robert Noyce in the late 1950s, was the first commercially available integrated circuit.
