    摘要: The present invention relates to a process for improved interfacial adhesion of dielectrics using patterned roughing. Improved adhesion strength between layers and substrates can be achieved through increasing the roughness of the interface between the materials. Roughness may including any disturbance of an otherwise generally smooth surface, such as grooves, indents, holes, trenches, and/or the like. Roughing on the interface may be achieved by depositing a material on a surface of the substrate to act as a mask and then using an etching process to induce the roughness. The material, acting as a mask, allows etching to occur on a fine, or sub-miniature, scale below the Scale achieved with a conventional photo mask and lithography to achieve the required pattern roughing. Another material is then deposited on the roughened surface of the substrate, filling in the roughing and adhering to the substrate.
