Abstract: A manufacturing method of a semiconductor device according to an embodiment implants impurities into a central portion of a polishing target film or an outer peripheral portion of the central portion of the polishing target film to cause an impurity concentration in the outer peripheral portion of the polishing target film and an impurity concentration in the central portion thereof to be different from each other, thereby modifying a surface of the polishing target film. The modified surface of the polishing target film is polished by a CMP method.

Abstract: A method is described for manufacturing a micromechanical structure, in which a structured surface is created in a substrate by an etching method in a first method step, and residues are at least partially removed from the structured surface in a second method step. In the second method step, an ambient pressure for the substrate which is lower than 60 Pa is set and a substrate temperature which is higher than 150° C. is set.

Abstract: System and method for filling vias in integrated circuits A preferred embodiment comprises forming a spacer layer on a substrate, forming a via with walls and a bottom in the spacer layer, depositing a conformal conductive layer on the spacer layer and on the walls and bottom of the via, spinning-on a photo-definable material on the conductive layer, forming a fill layer on the conductive layer and filling the via, exposing portions of the fill layer to an exposing light using a photomask, developing the fill layer to remove select portions of the fill layer and leave a portion of the fill layer filling the via, and removing the spacer layer. The use of a spin-on photo-definable material increases the material's filling and planarizing capabilities, while enabling a reduction in the number of process steps, which may reduce the likelihood of manufacturing defects, thereby increasing manufacturing yield.
