Inclusions of carbon in ingots of silicon carbide grown by

Dec 17, 2008· The problem of the appearance of carbon inclusions in single-crystal silicon carbide ingots grown by the modified Lely method (the so-called graphitization of the ingot) is analyzed. It is shown that the process of graphitization of the ingot is not related to a deficit of silicon in the growth cell; in contrast, it is excess of silicon at the growth surface that inhibits the ingot growth rate

Navarro SiC - Silicon Carbide

Silicon carbide (SiC) is a synthetic material with an exceptional hardness, highly wear resistance and chemically inert to alkalis and acids. It was discovered in 1893 by Henri Moissani (France) while examining rock samples from a meteorite crater loed in Devil''s Canyon (Arizona, United States).

Disco develops laser ingot slicing method to speed SiC

Existing methods for slicing wafers from a silicon carbide ingot mainly use multiple diamond wire saws for mass-producing wafers because the processing time is long due to the high rigidity of SiC. The nuer of wafers produced from a single ingot is also small due to the large amount of material lost in the slicing sections.

Solar Components

Blocks or ingots of silicon are grown in vacuum furnaces and then ground and sawn into solid beams. Sophistied wire saws cut the beams either with diamond coated wire or slurry of silicon carbide (SiC). Many thousands of wafers are sawn simultaneously on production wire systems and a wire failure must be avoided to prevent the loss of

Silicon Wafer Processing | How Are Silicon Wafers Made?

To grow an ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. Once the polycrystalline and dopant coination has been liquefied, a single silicon crystal, the seed, is positioned on top of the melt, barely touching the surface. The seed has the same crystal orientation required in the finished ingot.
