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.
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.
The workers in a semiconductor fabrication facility are required to wear cleanroom suits to protect the devices from contamination by humans. [139] To increase yield, FOUPs and semiconductor capital equipment may have a mini environment with ISO class 1 level of dust, and FOUPs can have an even cleaner micro environment.
semiconductor – a material with an electrical conductivity value falling between that of a conductor and an insulator; its resistivity falls as its temperature rises; silicon – the semiconductor material used most frequently as a substrate in electronics; silicon on insulator (SoI) – a layered silicon–insulator–silicon substrate
It is often desirable to pattern a film into distinct features or to form openings (or vias) in some of the layers. These features are on the micrometer or nanometer scale and the patterning technology is what defines microfabrication. This patterning technique typically uses a 'mask' to define portions of the film which will be removed.
The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits. Its roots can be traced to the invention of the transistor by Shockley , Brattain , and Bardeen at Bell Labs in 1948.
The rise in foundry sales came from "advanced packaging," a process in which Intel can combine pieces of chips made by another company to create a more powerful chip. (Reporting by Yuvraj Malik in ...
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.
