Its disadvantages include above all the price: whilst two-inch silicon wafers cost only a few dollars, the value of similar silicon carbide wafers runs into thousands. Low quality silicon carbide crystals are a popular abrasive material, also used in bulletproof vests and in the brake discs of the world''s most expensive cars, such as Laorghini or Bugatti.
TOKYO, Oct 02, 2015 - (ACN Newswire) - Showa Denko (SDK) (TOKYO: 4004) has developed a new grade of silicon carbide (SiC) epitaxial wafers for power devices with very low defect density. SDK will this month start commercial shipments of the new grade, in two different sizes of four inches (100mm) and six inches (150mm) in diameter, under the trade name of "High-Grade Epi ("HGE")".
Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More
The consumer market is highly price-sensitive, and it is here that cubic silicon carbide, 3C-SiC, comes in. 3C-SiC is most efficient at voltages between 600 and 1200V and the aim is to build these devices on large siliocn wafers for cost effective manufacturing by overcoming defects in the interface between the cubic silicon carbide and the silicon substrate.

The POI volume production method makes use of the same "smart-cut" process used by Soitec for the production of SOI and silicon-carbide wafers. After multiple years of research collaboration with Qualcomm, Soitec has agreed to make POI wafers in high volume for use in Qualcomm Technologies’ RF filters going to smartphones RF front end modules.
Turning the circular discs of silicon or silicon carbide - the wafers - into semiconductor chips involves an elaborate manufacturing process that can last up to 14 weeks. In several chemical and physical processes, the wafers acquire ultra-fine structures that will subsequently make up the tiny chips, each of which measures just a few millimeters.
