Abstract: A method and composition for removing silicon-containing particulate material, such as silicon nitrides and silicon oxides, from patterned Si/SiO2 semiconductor wafer surfaces is described. The composition includes a supercritical fluid (SCF), an etchant species, a co-solvent, a surface passivator, a binder, deionized water, and optionally a surfactant. The SCF-based compositions substantially remove the contaminating particulate material from the wafer surface prior to subsequent processing, thus improving the morphology, performance, reliability and yield of the semiconductor device.

Abstract: A method and apparatus for cleaning residue from components of an ion source region of an ion implanter used in the fabrication of microelectronic devices. To effectively remove residue, the components are contacted with a gas-phase reactive halide composition for sufficient time and under sufficient conditions to at least partially remove the residue. The gas-phase reactive halide composition is chosen to react selectively with the residue, while not reacting with the components of the ion source region or the vacuum chamber.

Abstract: A method and composition for removing silicon-containing sacrificial layers from Micro Electro Mechanical System (MEMS) and other semiconductor substrates having such sacrificial layers is described. The etching compositions include a supercritical fluid (SCF), an etchant species, a co-solvent, and optionally a surfactant. Such etching compositions overcome the intrinsic deficiency of SCFs as cleaning reagents, viz., the non-polar character of SCFs and their associated inability to solubilize polar species that must be removed from the semiconductor substrate. The resultant etched substrates experience lower incidents of stiction relative to substrates etched using conventional wet etching techniques.

Abstract: An adsorbent having porosity expanded by contact with a first agent effecting such expansion and a pressurized second agent effecting transport of the first agent into the porosity, wherein the adsorbent subsequent to removal of the first and second agents retains expanded porosity. The adsorbent can be made by an associated method in which materials such as water, ethers, alcohols, organic solvent media, or inorganic solvent media can be utilized as the first agent for swelling of the porosity, and helium, argon, krypton, xenon, neon, or other inert gases can be employed as the pressurized second agent for transport of both agents into the porosity of the adsorbent, subsequent to which the agents can be removed to yield an adsorbent of increased capacity for sorbable fluids, e.g., organometallic compounds, hydrides, halides and acid gases.

The flow circuitry is constructed and arranged to flow dispensed gas from an on-stream gas supply vessel to multiple sticks of the flow circuitry, with each of the multiple sticks being joined in gas flow communication to a respective gas-utilizing process unit. The flow circuitry is valved to enable sections of the flow circuitry associated with respective ones of the multiple sticks to be isolated from other sections of the flow circuitry, so that process gas can be flowed to one or more of the sticks, while other sticks are being evacuated and purged, or otherwise are closed to dispensed gas flow therethrough.
