Trimethylsilane or trimethylsilyl hydride, is a gas at ambient conditions with the formula C₃H₁₀Si. It is very flammable. Trimethylsilane is used in the semi-conductor industry as precursor to deposit dielectrics and barrier layers via plasma-enhanced chemical vapor deposition (PE-CVD).. It is also used a source gas to deposit TiSiCN hard coatings via plasma-enhanced magnetron sputtering (PEMS). It has also been used to deposit silicon carbide hard coatings via low-pressure chemical vapor deposition (LP-CVD) at relatively low temperatures <1000ᵒC. It is an expensive gas but safer to use than silane (SiH₄); and produces properties in the coatings that cannot be undertaken by multiple source gases containing silicon and carbon.
Method of depositing low k films using an oxidizing plasma
InactiveUS6593247B1Semiconductor/solid-state device detailsSolid-state devicesTrimethylsilaneSilicon oxide
A silicon oxide layer is produced by plasma enhanced oxidation of an organosilicon compound to deposit films having a carbon content of at least 1% by atomic weight. Films having low moisture content and resistance to cracking are deposited by introducing oxygen into the processing chamber at a flow rate of less than or equal to the flow rate of the organosilicon compounds, and generating a plasma at a power density ranging between 0.9 W / cm2 and about 3.2 W / cm2. An optional carrier gas may be introduced to facilitate the deposition process at a flow rate less than or equal to the flow rate of the organosilicon compounds. The organosilicon compound preferably has 2 or 3 carbon atoms bonded to each silicon atom, such as trimethylsilane, (CH3)3SiH. An oxygen rich surface may be formed adjacent the silicon oxide layer by temporarily increasing oxidation of the organosilicon compound.

An enhanced thermal interface material (TIM) gap filler for filling a gap between two substrates (e.g., between a coldplate and an electronics module) includes microcapsules adapted to rupture in a magnetic field. The microcapsules, which are distributed in a TIM gap filler, each have a shell that encapsulates a solvent. One or more organosilane-coated magnetic nanoparticles is / are covalently bound into the shell of each microcapsule. In one embodiment, (3-aminopropyl) trimethylsilane-coated magnetite nanoparticles are incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. To enable easy removal of one substrate affixed to another substrate by the enhanced TIM gap filler, the substrates are positioned within a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles. The ruptured microcapsule shells release the solvent, which dissolves and / or swells the TIM gap filler, thereby reducing the bond strength between the substrates.

A semiconductor device having improved adhesiveness between films composing an interlayer insulating film is presented by providing multilayered films in the interlayer insulating films having film density distribution, in which the film density is gradually changes. A SiOC film is deposited to a thickness of 300 nm via a plasma CVD process, in which a flow rate of trimethylsilane gas is stepwise increased. In this case, the film density of the deposited SiOC film is gradually decreased by stepwise increasing the flow rate of trimethylsilane gas. Since trimethylsilane contains methyl group, trimethylsilane has more bulky molecular structure in comparison with monosilane or the like. Thus, the film density is decreased by increasing the amount of trimethylsilane in the reactant gas.
