摘要： A new method and apparatus is provided that can be applied to clean outer edges of semiconductor substrates. Under the first embodiment of the invention, a brush is mounted on the surface of the substrate around the periphery of the substrate, chemicals are fed to the surface that is being cleaned by means of a hollow core on which the cleaning brush is mounted. The surface that is being cleaned rotates at a relatively high speed thereby causing the chemicals that are deposited on this surface (by the brush) to remain in the edge of the surface. Under the second embodiment of the invention, a porous roller is mounted between a chemical reservoir and the surface that is being cleaned, the surface that is being cleaned rotates at a relatively high speed. The chemicals that are deposited by the interfacing porous roller onto the surface that is being cleaned therefore remain at the edge of this surface thereby causing optimum cleaning action of the edge of the surface. After contaminants have been removed in this manner from the surface, the surface can be further cleaned by applying DI water.

摘要： A method of preventing copper transport on a semiconductor wafer, comprising the following steps. A semiconductor wafer having a front side and a backside is provided. Metal, selected from the group comprising aluminum, aluminum-copper, aluminum-silicon, and aluminum-copper-silicon is sputtered on the backside of the wafer to form a layer of metal. The back side sputtered aluminum layer may be partially oxidized at low temperature to further decrease the copper penetration possibility and to also provide greater flexibility in subsequent copper interconnect related processing. Once the back side layer is in place, the wafer can be processed as usual. The sputtered back side aluminum layer can be removed during final backside grinding.

摘要： A method for cleaning a semiconductor structure using vapor phase condensation with a thermally vaporized cleaning agent, a hydrocarbon vaporized by pressure variation, or a combination of the two. In the thermally vaporized cleaning agent process, a semiconductor structure is lowered into a vapor blanket in a thermal gradient cleaning chamber at atmospheric pressure formed by heating a liquid cleaning agent below the vapor blanket and cooling the liquid cleaning agent above the vapor blanket causing it to condense and return to the bottom of the thermal gradient cleaning chamber. The semiconductor structure is then raised above the vapor blanket and the cleaning agent condenses on all of the surfaces of the semiconductor structure removing contaminants and is returned to the bottom of the chamber by gravity. In the pressurized hydrocarbon process, a semiconductor structure is placed into a variable pressure cleaning chamber, having a piston which changes the pressure by reducing or increasing the volume of the chamber. The semiconductor structure first exposed to the hydrocarbon in vapor phase, then the piston is lowered to condense the hydrocarbon. A semiconductor structure can be cleaned by either or both of these processes by repetitive vaporization/condensation cycles.
