    摘要: A chemical mechanical polishing method is disclosed. The method includes forming a film on a wafer having at least one trench structure thereon; polishing the surface of the film by providing a polishing composition to provide a first polished surface; rinsing the first polished surface with a rinse composition to provide a rinsed surface; and polishing the rinsed surface by providing a second polishing composition to provide a second polished surface.

    摘要: A method for forming shallow trench isolation structures is disclosed. The methods include providing a substrate having an upper surface and having an opening extending down from said upper surface, providing a first dielectric layer over at least a portion of the upper surface of the substrate and filling the opening, providing a second dielectric layer over the first dielectric layer, and removing portions of the first and second dielectric layers, wherein the first dielectric layer has a higher index of refraction than the second dielectric layer.
