Abstract:
A cleaning solution and method for removing submicron particles from the surface of an electronic substrate such as a semiconductor wafer. The cleaning solution comprises a polycarboxylate polymer, a base and water. The method comprises the step of contacting a surface of the substrate with a cleaning solution comprised of the polycarboxylate polymer. Additional optional steps in the method include applying acoustic energy to the cleaning solution and/or rinsing the surface with a rinsing solution with or without the application of acoustic energy to the rinsing solution.
Abstract:
A method and cleaning solution for cleaning electronic substrates, such as a semiconductor wafers, hard disks, photomasks or imprint molds. The method comprises the steps of contacting a surface of the substrate with a cleaning solution comprised of a polyphosphate, and then removing the cleaning solution from the surface. Additional optional steps include applying acoustic energy to the cleaning solution while the cleaning solution is in contact with the surface, and removing the cleaning solution from the surface by rinsing the surface with a rinsing solution with or without the application of acoustic energy. The cleaning solution comprises a polyphosphate, such as any of the water soluble polyphosphates. Depending on the application, the cleaning solution may also comprise a base and/or a quantity of suspended particles. Complexing agents, amines, biocides, surfactants and/or other substances, may also be added to the cleaning solution.
