Jlc. Fonseca et al., PLASMA-ENHANCED CHEMICAL-VAPOR-DEPOSITION OF ORGANOSILICON MATERIALS - A COMPARISON OF HEXAMETHYLDISILANE AND TETRAMETHYLSILANE PRECURSORS, Macromolecules, 29(5), 1996, pp. 1705-1710
Plasma polymerization of hexamethyldisilane ([CH3]3SiSi[CH3](3)) and t
etramethylsilane ([CH3]Si-4) has been investigated by XPS, FTIR, solid
state NMR, and plasma emission diagnostics. Thin carbosilane films an
d powders can be deposited by this method. Hexamethyldisilane is found
to undergo glow discharge polymerization much more readily than tetra
methylsilane; this has been attributed to the chromophoric ''Si-Si'' b
ond contained in the former precursor.
