The X-FAB Silicon Foundries is a group of semiconductor foundries. The group specializes in the fabrication of analog and mixed-signal integrated circuits for fabless semiconductor companies , as well as MEMS and solutions for high voltage applications. [ 1 ]
Lithographer Chris Mack claimed in 2012 that the overall price per die for 450 mm wafers would be reduced by only 10–20% compared to 300 mm wafers, because over 50% of total wafer processing costs are lithography-related. Converting to larger 450 mm wafers would reduce price per die only for process operations such as etch where cost is ...

In 1991, the company released the first commercial silicon carbide wafer. [5] In 1993, the company became a public company via an initial public offering. [6] In 1999, the company name was changed from Cree Research to Cree, Inc. [7] In 2011, the company acquired Ruud Lighting for $525 million. [8]
Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .
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 ...
In electronic engineering, a through-silicon via (TSV) or through-chip via is a vertical electrical connection that passes completely through a silicon wafer or die. TSVs are high-performance interconnect techniques used as an alternative to wire-bond and flip chips to create 3D packages and 3D integrated circuits.
