A fluid distribution system for supplying a gas to a process facility such as a semiconductor manufacturing plant. The system includes a main fluid supply vessel coupled by flow circuitry to a local sorbent-containing supply vessel from which fluid, e.g., low pressure compressed gas, is dispensed to a fluid-consuming unit, e.g., a semiconductor manufacturing tool. A fluid pressure regulator is disposed in the flow circuitry or the main liquid supply vessel and ensures that the gas flowed to the fluid-consuming unit is at desired pressure. The system and associated method are particularly suited to the supply and utilization of liquefied compressed gases such as trimethylsilane, arsine, phosphine, and dichlorosilane.

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.

Systems and methods of purifying a silicon-containing material include the step of directing the silicon-containing material in a liquid state through an adsorption unit including an adsorbent material to facilitate adsorption of at least one component from the silicon-containing material. Alternatively, the silicon-containing material is directed, in liquid state and/or gaseous state, through two or more purification units, including an adsorption unit, a vaporization unit, a filter unit and a condenser. The silicon-containing material can be a low-k silicon-containing material such as trimethylsilane, tetramethylsilane, dimethyldimethoxysilane, tetramethylcyclotetrasiloxane, octamethylcyclotetrasiloxane, dimethylphenyl silane, and dimethyldivinyl silane.

A method of forming a SiCOH etch stop layer in a copper damascene process is described. A substrate with an exposed metal layer is treated with H₂ or NH₃ plasma to remove metal oxides. Trimethylsilane is flowed into a chamber with no RF power at about 350° C. to form at least a monolayer on the exposed metal layer. The SiCOH layer is formed by a PECVD process including trimethylsilane and CO₂ source gases. Optionally, a composite SiCOH layer comprised of a low compressive stress layer on a high compressive stress layer is formed on the substrate. A conventional damascene sequence is then used to form a second metal layer on the exposed metal layer. Via Rc stability is improved and a lower leakage current is achieved with the trimethylsilane passivation layer. A composite SiCOH etch stop layer provides improved stress migration resistance compared to a single low stress SiCOH layer.
