Abstract
A method for forming a dielectric insulating layer with increased hydrophilicity for improving adhesion of an adjacently deposited material layer in semiconductor device manufacturing including providing a semiconductor wafer having a process surface for forming a dielectric insulting layer thereover; depositing the dielectric insulating layer; and, subjecting the dielectric insulating layer including an exposed surface to a hydrophilicity increasing treatment including at least one of a dry plasma treatment and a wet process including contacting the exposed surface with a hydrophilicity increasing solution including a surfactant said wet process followed by a baking process to improve an adhesion of an adjacently deposited material layer.
