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 process for the manufacture of semiconductor devices comprising the chemical-mechanical polishing of a substrate or layer containing at least one III-V material in the presence of a chemical-mechanical polishing composition (Q1) comprising (A) inorganic particles, organic particles, or a mixture or composite thereof, (B) at least one amphiphilic non-ionic surfactant having (b1) at least one hydrophobic group; and (b2) at least one hydrophilic group selected from the group consisting of polyoxyalkylene groups comprising (b22) oxyalkylene monomer units other than oxyethylene monomer units; and (M) an aqueous medium.
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.

Abstract:
PROBLEM TO BE SOLVED: To provide a production process for facilitating machining on the surface of a workpiece in following process by planarizing protrusions and recesses on the surface of the workpiece, e.g. a semiconductor substrate or a micromachine, being subjected to micromachining easily with higher planarity as compared with prior art even when the depth of the recesses is different. SOLUTION: The production process for facilitating machining on the surface in following process by planarizing protrusions and recesses on the surface of a workpiece 1 comprises a step for coating the surface with photosensitive resin 2, a step for exposing the photosensitive resin using a gray scale mask 3 corresponding to the surface profile of the photosensitive resin coating, and a step for developing exposed photosensitive resin and removing uncured photosensitive resin (shaded portion).
