Abstract:

An apparatus and process for cleaning residual matter, photoresist and other foreign materials off wafers, substrates and semiconductor work pieces including photomasks, compact discs, flat panel displays using megasonic acoustic wave action techniques in conjunction with supercritical fluid cleaning processes, and in particular, for coupling megasonics techniques with supercritical carbon dioxide processing with co-solvents and surfactants, using cycles of soak, rapid decompression and flushing, to improve cleaning capability and to remove submicron particles from the surfaces of wafers.

E21B 4316
E21B 4322

US Classification:

516102

Abstract:

A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous fluid containing a surfactant gelling agent into the system. The surfactant gelling agents are, for example, fatty aliphatic amidoamine oxides, salts of an alkoxylated monoamine with an aromatic dicarboxylic acid, and salts of an alkyldiamine with an aromatic dicarboxylic acid. The surfactant gelling agents can be adsorbed onto particulate supports to facilitate delivery of the gelling agent. The additives may be incorporated in the viscoelastic fluid to tailor its use in hydraulic fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.

A01N 4336

US Classification:

514642

Abstract:

Biocidal preservatives for use especially in preventing rotting and deterioration of wood include quaternary ammonium compounds which preferably have a fatty aliphatic substituent on the quaternary nitrogen atom. Especially preferred are cocoalkyl substituents. Other substituents can include alkoxy groups, arenes, and heterocyclic groups with or without ring substitutions, for example. The quaternary ammonium compound can also contain an amine nitrogen and can be complexed with copper.
