Transistor and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926 but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.
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
