In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer ...
The primary application of monocrystalline silicon is in the production of discrete components and integrated circuits.Ingots made by the Czochralski method are sliced into wafers about 0.75 mm thick and polished to obtain a regular, flat substrate, onto which microelectronic devices are built through various microfabrication processes, such as doping or ion implantation, etching, deposition ...
The funds for projects in Texas and Missouri will establish the first high-volume U.S. production of 300-mm wafers for advanced semiconductors and expand production of silicon-on-insulator wafers ...
Wafer processing is separated into FEOL and BEOL stages. FEOL processing refers to the formation of the transistors directly in the silicon. The raw wafer is engineered by the growth of an ultrapure, virtually defect-free silicon layer through epitaxy.
WASHINGTON (Reuters) -Wolfspeed is set to receive $750 million in government grants for its new North Carolina silicon carbide wafer manufacturing plant facility, the U.S. Commerce Department said ...
