This is a list of semiconductor fabrication plants, factories where integrated circuits (ICs), also known as microchips, are manufactured.They are either operated by Integrated Device Manufacturers (IDMs) that design and manufacture ICs in-house and may also manufacture designs from design-only (fabless firms), or by pure play foundries that manufacture designs from fabless companies and do ...
The overall shape is cylindrical and the equipment is arranged vertically, usually supported by four legs. The overall look is similar to a large smokestack. The bottom of the cylinder is fitted with doors which swing down and out to 'drop bottom'. The top where gases escape can be open or fitted with a cap to prevent rain from entering the cupola.
In the microelectronics industry, a semiconductor fabrication plant, also called a fab or a foundry, is a factory where integrated circuits (ICs) are manufactured. [1]The cleanroom is where all fabrication takes place and contains the machinery for integrated circuit production such as steppers and/or scanners for photolithography, etching, cleaning, and doping.
Equipment for carrying out these processes is made by a handful of companies. All equipment needs to be tested before a semiconductor fabrication plant is started. [115] These processes are done after integrated circuit design. A semiconductor fab operates 24/7 [116] and many fabs use large amounts of water, primarily for rinsing the chips. [117]
Pontiac Foundry: Pontiac, Michigan: United States: Iron castings of engine parts. 1927: 1987: Was part of GM's Central Foundry Division. Was Plant 6 of Pontiac's Assembly complex in Pontiac, Michigan. Demolished in 1995. A U.S. Postal Service distribution center located at 711 N. Glenwood Ave. now occupies the approximate area where the foundry ...
Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication (or fab) to a specialized manufacturer called a semiconductor foundry. These foundries are typically, but not exclusively, located in the United States , mainland China , and Taiwan .
The fabless company concentrates on the research and development of an IC-product; the foundry concentrates on manufacturing and testing the physical product. If the foundry does not have any semiconductor design capability, it is a pure-play semiconductor foundry. An absolute separation into fabless and foundry companies is not necessary.
In 1901, piping and heating contractor W. Frank Dowd established the Charlotte Pipe and Foundry Company in Charlotte, North Carolina, United States. [1] The foundry operated with 25 employees and cast iron soil pipes and fittings. [2] The company focused its efforts on iron casting for much of its early history. [1]
