摘要: The invention relates to compositions and methods for the selective wet etching of a surface of a microelectronic device that contains both silicon nitride (SiN) and polysilicon. An etching composition as described comprises phosphoric acid, certain polysilicon corrosion inhibitors, along with certain silanes. The combination of the two components was found to greatly improve the selectivity of the silicon nitride etching composition in the presence of polysilicon.

摘要: A removable filter cartridge includes a filter housing containing a filter and a sealing valve coupled to an open end of the filter housing. The sealing valve configured to removably couple the removable filter cartridge to a filter head. An open position allows fluid to flow into and out of the internal volume of the filter housing. A closed position seals the filter housing. A method for retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.

摘要: Filter cartridges and manifold blocks for filter manifold systems are described. The filter cartridges include flanges surrounding openings at first and second ends of the filter cartridge, with face seals in the flanges. Manifold blocks include end blocks, at least one of which is movable so that the distance between the end blocks can be changed. When a filter cartridge is installed into the manifold by engagement of the flanges with slots in the manifold end blocks, a fluid pathway is formed through a first manifold end block, into the filter cartridge, through the filter cartridge, out of the filter cartridge and into a second manifold end block. The fluid pathway is sealed by the face seals where the flow is from a manifold end block into or out of the filter cartridge.

摘要: The disclosure provides certain porous membranes comprised of cyclic polyolefin polymers, such as poly(norbornene)s. In one embodiment, a poly(norbornene) polymer is dissolved in tetrahydrofuran, cast into a film and subjected to solvent induced phase separation to provide a porous filter membrane (i.e., film).

摘要: Described are filter materials including a polyol ligand, such as n-methylglucamine, and/or a polyphosphonic acid ligand, which are highly effective for filtering metals or metal ions from fluids. The filter materials can be particularly useful to filter basic and acidic fluid compositions, such as those used for wet etching, removing photoresist, and cleaning steps in microelectronic device manufacturing.
