    摘要: In a method of manufacturing a semiconductor device, an inorganic insulating layer is formed to cover a conductive layer, a polyimide layer is formed to cover the inorganic insulating layer, and a photo-resist layer is formed to cover the polyimide layer. An opening portion is formed by use of development or a wet etching to pass through the photo-resist layer and the polyimide layer to the inorganic insulating film. Then, after the photo-resist layer is removed, heat treatment is performed of the polyimide layer. Subsequently, the inorganic insulating film is etched using the polyimide layer having the opening portion as a mask. The photo-resist layer has a film thickness in a range of 4 to 10 &mgr;m, and the polyimide layer has a film thickness in a range of 5 to 20 &mgr;m.

    摘要: In a CMP (chemical and mechanical polishing) method in which an insulating film is formed on one surface (back surface) of a semiconductor substrate and then the insulating film is chemically and mechanically polished with abrasive, an insulating thin film is formed on the surface of the semiconductor substrate on which no insulating film is provided and silicon is exposed to the outside, and a hydrophilic film is formed on the surface of the insulating thin film. Thereafter, the CMP is conducted to polish the insulating film on the back surface, and then the abrasive is chemically and physically removed. Accordingly, by providing the hydrophilic thin film on the back surface of the semiconductor substrate, it is avoidable that the abrasive on the back surface of the semiconductor substrate is partially dried and the abrasive grains are fixed to the back surface, so that the effect of removing the abrasive in the subsequent step can be improved.

    摘要: The invention relates to an apparatus for polishing wafers in the fabrication of semiconductor integrated circuits. The apparatus has a turntable on which a polishing pad of polyurethane foam is placed. The pad has a multiplicity of cavities in the polishing surface. In periodically dressing the pad, abrasive grains of diamond fall off the dressing tool, and some of the fallen abrasive grains remain in the cavities in the pad surface even though the pad surface is washed by water. According to the invention the polishing apparatus includes a cleaning device to drive abrasive grains out of the cavities. The cleaning device has a cylindrical body which rotates above the polishing pad. In an embodiment the cleaning device is a rotary brush having a multiplicity of needle-like parts of a synthetic resin on the cylindrical outer surface. The needle-like parts intrude into the cavities in the pad surface and flip abrasive grains out of the cavities. In another embodiment the cleaning device has an elastic covering on the cylindrical body. The elastic covering is squeezed into the cavities to temporarily close the opening of the cavities and reduce the air pressure in the cavities. When the elastic covering leaves the cavities a rush of the air into the cavities drives diamond grains out of the cavities.
