Alcatel-Lucent 1947, John Bardeen, Walter Brattain, William Shockley of Bell Labs invented the transistor. In 1956, they received a Nobel Prize for their invention. The transistor led to an electronics revolution during the post-war boom. The transition from vacuum tubes to transistors enabled all technologies to be built on a smaller scale and use less electricity. Items that before required large dedicated spaces, could now fit into a home or even on a kitchen counter. In 1954, Gerald Pearson, Darryl Chapin and Calvin Fuller invented the solar cell. Telstar, the first active communications satellite also developed by Bell Labs and launched
Invention of the integrated circuit application by Lehovec. Noyce revised his application and in 1964 received and . In early 1959, Noyce solved another important problem, the problem of interconnections that hindered mass-production of ICs. According to the colleagues from the traitorous eight his idea was self-evident: of course, the passivating oxide layer forms a natural barrier between the chip and the metallization layer. According to Turner Hasty, who worked with Kilby and Noyce, Noyce planned to make the microelectronic patents of Fairchild accessible to a wide range of companies, similar to Bell Labs which in 1951–1952 released their transistor technologies. Noyce submitted his application
