US Patent:

6344243, Feb 5, 2002

Filed:

Aug 2, 2001

Appl. No.:

09/921376

Inventors:

James B. McClain - Carrboro NC

Assignee:

Micell Technologies, Inc. - Raleigh NC

International Classification:

B05D 100

US Classification:

4273881, 4273899, 4273934, 427394, 427435, 427439

Abstract:

A method of treating a substrate comprises contacting a surface of said substrate, with a pressurized fluid comprising carbon dioxide and a surface treatment component, the surface treatment component being entrained in the pressurized fluid and contacting the surface so that the surface treatment component lowers the surface tension of the surface of the substrate and treats the substrate. The contacting step is preferably carried out by immersion, the fluid is preferably a liquid or supercritical fluid, the substrate is preferably a metal or fabric substrate, and the surface treatment component is preferably a fluoroacrylate polymer.

Abstract:

A method for carrying out a catalysis reaction in carbon dioxide comprising contacting a fluid mixture with a catalyst bound to a polymer, the fluid mixture comprising at least one reactant and carbon dioxide, wherein the reactant interacts with the catalyst to form a reaction product. A composition of matter comprises carbon dioxide and a polymer and a reactant present in the carbon dioxide. The polymer has bound thereto a catalyst at a plurality of chains along the length of the polymer, and wherein the reactant interacts with the catalyst to form a reaction product.

Abstract:

Methods for cleaning a microelectronic substrate in a cluster tool are described that include placing the substrate in a pressure chamber of a module in a cluster tool; pressurizing the pressure chamber; introducing liquid CO into the pressure chamber; cleaning the substrate in the pressure chamber; removing the liquid CO from the pressure chamber, depressurizing the pressure chamber, and removing the substrate from the pressure chamber. Apparatus for processing a microelectronic substrate are also disclosed that that include a transfer module, a first processing module that employs liquid carbon dioxide as a cleaning fluid coupled to the transfer module, a second processing module coupled to the transfer module, and a transfer mechanism coupled to the transfer module. The transfer mechanism is configured to move the substrate between the first processing module and the second processing module.

International Classification:

B01D 1100

US Classification:

210634

Abstract:

The separation of a contaminant from a substrate that carries the contaminant is disclosed. The process comprises contacting the substrate to a carbon dioxide fluid containing an amphiphilic species so that the contaminant associates with the amphiphilic species and becomes entrained in the carbon dioxide fluid. The substrate is then separated from the carbon dioxide fluid, and then the contaminant is separated from the carbon dioxide fluid.
