Abstract: The disclosure pertains to compositions and methods for modifying or refining the surface of a wafer suited for semiconductor fabrication. The compositions include working liquids useful in modifying a surface of a wafer suited for fabrication of a semiconductor device. In some embodiments, the working liquids are aqueous solutions of initial components substantially free of loose abrasive particles, the components including water, a surfactant, and a pH buffer exhibiting at least one pKa greater than 7. In certain embodiments, the pH buffer includes a basic pH adjusting agent and an acidic complexing agent, and the working liquid exhibits a pH from about 7 to about 12. In further embodiments, the disclosure provides a fixed abrasive article comprising a surfactant suitable for modifying the surface of a wafer, and a method of making the fixed abrasive article. Additional embodiments describe methods that may be used to modify a wafer surface.

Abstract: A method for polishing a wafer comprising an aqueous solution having a pH in the range of 6 to 8, wherein the aqueous solution comprises at least one compound selected from the group consisting of a polymethacrylic acid, a polysulfonic acid, and combinations thereof, and wherein the compound is present in the range of 1.5 to 4 percent by weight of the aqueous solution. The wafer polishing solution can be adjusted to control cut rate and selectivity for modifying semiconductor wafers using a fixed abrasive CMP process.

Abstract: An apparatus including a fixed abrasive article interposed between a substrate and a support assembly. The support assembly creates regions of high and low erosion force at the interface between the substrate and the fixed abrasive article. The high erosion force is sufficient to activate the fixed abrasive article.

Abstract: A multi-stage liquid elevator which is assembled from individual stages is a fabricated from ordinary pipe components and has no moving parts. Each elevator stage consists of a reservoir defined by a casing enclosing an inlet pipe and an outlet pipe. A coupling connects any two stages of the elevator together. As many stages as required can be joined together to construct a multi-stage liquid elevator of any desired length. Each stage is fabricated to a length compatible with the available gas pressure. Enough pressure must be available to move a column of liquid a vertical distance equal to or greater than the length of one stage of the elevator.

Abstract: A multi-stage liquid elevator is assembled from individual stages in which each elevator stage is fabricated from ordinary pipe components and has no moving parts. When inserted into an natural gas well, the elevator is powered by the gas pressure available in the well. At each stage, the liquid and gas from the previous stage are forced into the inlet pipe and the liquid collects in the reservoir until enough gas pressure builds up in the stage to force the liquid up the outlet pipe to the next stage. The elevator requires only enough pressure from the well to move a column of liquid a vertical distance equal to or greater than the length of one stage of the elevator.
