A Method for Defect Delineation in Silicon Carbide Using
Jan 20, 2014· Defect evaluation of silicon carbide (SiC) wafers can be accomplished by potassium hydroxide (KOH) etching. The method described in this work employs etching by KOH in a vapor phase rather than in a liquid phase and this method allows reliable etching of both Si- and C-faces and furthermore it allows the delineation of defects on alternate orientation planes of SiC.

The standard free energy change (G 0) of the reactions (1) and (2) can be calculated to search the possibility for formation of the SiC phase from SiO and CO vapors.In the present experiment, measured CO and CO 2 gas pressure were about 10 3 Pa, and 10-2 Pa, respectively. The calculated stability diagram in the SiO-CO-CO 2 gas phase at 1523 K and P CO2 = 10-2 Pa is shown in Fig. 1 as …

How silicon is made - material, making, history, used
When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.
Deposition of silicon carbide ﬁlms using a high vacuum
Silicon carbide ~SiC! thin ﬁlms were prepared on Si~100! substrates by high vacuum metalorganic chemical vapor deposition using a single-source precursor at various growth temperatures in the range of 700–1000°C. The precursor is diethylmethylsilane, and is used without carrier gas. The
Carbonization Layer Obtained by Acetylene Reaction with
Surface carbonization on Si (100) and Si (111) using acetylene as single carbon source was performed in a low-pressure chemical vapor deposition chaer using rapid thermal technique. The dependence of crystallinity, crystal orientation and bonding state of carbonization layer on acetylene flow rates, pressures, temperatures and times were evaluated using X-ray diffractometry and electron

Silicon carbide - Infogalactic: the planetary knowledge core
Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite.Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used
