--- title: "Invention of the Integrated Circuit" year: 1958 country: "United States" canonical: "https://recap.at/1958/integrated-circuit-invention" slug: "integrated-circuit-invention" recapType: "global_event" startDate: "1958-01-01" --- # Invention of the Integrated Circuit > Jack Kilby and Robert Noyce's simultaneous invention of the integrated circuit in 1958 was the foundational breakthrough that made miniaturization, computing, and the digital age itself possible. In 1958, engineers at Texas Instruments and Fairchild Semiconductor independently demonstrated that multiple transistors and other components could be built on a single piece of silicon—eliminating the need to wire components together by hand. This invention made electronics smaller, faster, cheaper, and more reliable, setting the stage for everything from pocket calculators to smartphones. ## Summary The first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic components in a monolithic semiconductor crystal in 1952. A year later, Harwick Johnson filed a patent for a prototype IC. Between 1953 and 1957, Sidney Darlington and Yasuo Tarui proposed similar chip designs where several transistors could share a common active area, but there was no electrical isolation to separate them from each other. ## Key facts - **First demonstration**: September 1958, Texas Instruments (Jack Kilby) - **Independent development**: Early 1959, Fairchild Semiconductor (Robert Noyce) - **Kilby's chip components**: 5 components (transistor, resistors, capacitors) - **Noyce's planar process advantage**: Manufacturing-friendly; became industry standard - **Nobel Prize recognition**: 2000 (Kilby; Noyce died in 1990) - **Integration density milestone**: 1971: Intel 4004 had 2,300 transistors on one chip ## Timeline - **1949-01-01** - Jacobi's integrated transistor amplifier patent Werner Jacobi (Germany) patents the first known integrated transistor amplifier concept. - **1958-09-12** - Kilby demonstrates first IC at Texas Instruments Jack Kilby successfully demonstrates an integrated circuit made of germanium with five components connected by wires on a single substrate. - **1959-02-01** - Noyce files planar IC patent at Fairchild Robert Noyce develops and files a patent for the planar process—a manufacturing method using silicon that proves more practical than Kilby's approach. - **1960-03-06** - First planar monolithic IC publicly demonstrated Fairchild Semiconductor publicly demonstrates a monolithic silicon integrated circuit using Noyce's planar process at the IRE Show in New York. - **1961-01-01** - Commercial IC production begins Both Texas Instruments and Fairchild begin commercial production of integrated circuits for military and aerospace applications. - **1965-04-19** - Moore's Law prediction Gordon Moore publishes observations that transistor density on chips doubles approximately every two years—a prediction that becomes foundational to IC industry planning. - **1971-11-15** - Intel 4004 microprocessor released Intel releases the 4004, a 4-bit microprocessor with 2,300 transistors—demonstrating IC density and complexity reaching consumer-viable levels. - **2000-10-10** - Kilby awarded Nobel Prize in Physics Jack Kilby receives the Nobel Prize in Physics for his part in the invention of the integrated circuit.
