Intel Tri-Gate Transistor using a fin-shaped source/drain for more surface area between the source and gate
Intel states that this technology also allows for lower voltages, resulting in up to a 50% reduction in power consumption while maintaining or even increasing overall performance. Intel Inc continues to use Tri-Gate transistors in the latest Haswell and Broadwell processors.
Integrated Circuits
The 3rd generation of modern electronic computers is known for using integrated circuits in place of individual transistors. Jack Kilby at Texas Instruments and Robert Noyce at Fairchild are both invented the integrated circuit (IC) in 1958 and 1959. An IC is a semiconductor circuit that contains multiple components on the same base or substrate material, which are usually connected without wires. The first diagram of IC invented by Kilby at TI in 1958 contained only one transistor, various resistors, and a capacitor on a single slab of germanium, and it featured fine gold “flying wires” to connect them. However, because the flying wires had to be individually connected, this type of diagram was not practical to manufacture. By comparison, Noyce designed the “planar” IC design in 1959, where all the components are diffused in or carved on a silicon base, including a layer of aluminum metal interconnects. In 1960, Fairchild built the first planar IC, formed of a flip-flop circuit with four transistors and five resistors on a round die only about 20mm2 in size. By comparison, the Intel Core i7 eight-core processor based on the 22nm Haswell-E microarchitecture inc 2.6 billion transistors and numerous other components on a single 376mm2 die!
