Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, ... particularly in the semiconductor industry. The higher silanes, such as ...
Stock and Somieski completed the hydrolysis of dichlorosilane by putting the solution of H 2 SiCl 2 in benzene in brief contact with a large excess of water. [3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
WESTON — A maker of chemicals used in the semiconductor industry will be expanding its plant in Lenawee County. ... head of Evonik’s silanes business line, said in the release. “We are ...
Silicon dioxide (usually called simply "oxide" in the semiconductor industry) may be deposited by several different processes. Common source gases include silane and oxygen, dichlorosilane (SiCl 2 H 2) and nitrous oxide [16] (N 2 O), or tetraethylorthosilicate (TEOS; Si(OC 2 H 5) 4). The reactions are as follows: [17] SiH 4 + O 2 → SiO 2 + 2 H 2
Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid. Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry.
Silane SiH 4, the parent. Binary silicon-hydrogen compounds (which are sometimes called silanes also) includes silane itself but also compounds with Si-Si bonds including disilane and longer chains. Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane is again the parent member. Examples: triethylsilane (HSi(C 2 H 5)
Silicon tetrachloride and trichlorosilane are intermediates in the production of ultrapure silicon in the semiconductor industry. Chlorosilanes obtained from crude silicon are purified by fractional distillation techniques and then reduced with hydrogen to give silicon of 99.999 999 999 % purity.
