Abstract: A method for producing abrasive agents includes: adding a silica to a manganese compound; heat-treating the manganese compound to which the silica has been added; forming abrasive grains by milling the manganese compound to which the silica has been added and which has been heat-treated; and adding a solvent to the abrasive grains.

Abstract: A trench is formed in a surface layer of a semiconductor substrate, the trench surrounding an active region. A lower insulating film made of insulating material is deposited over the semiconductor device, the lower insulating film filling a lower region of the trench and leaving an empty space in an upper region. An upper insulating film made of insulating material having therein a tensile stress is deposited on the lower insulating film, the upper insulating film filling the empty space left in the upper space. The upper insulating film and the lower insulating film deposited over the semiconductor substrate other than in the trench are removed.

Abstract: A semiconductor device is disclosed that includes a semiconductor substrate, a device region disposed at a predetermined location of the semiconductor substrate, and a shallow trench isolation region that isolates the device region. The shallow trench isolation region includes a trench, a nitride film liner disposed at an upper portion of a side wall of the trench, and a thermal oxide film disposed at a lower portion of the side wall of the trench. The shallow trench isolation is arranged such that the width of a second portion of the shallow trench isolation region at which the thermal oxide film is disposed may be wider than the width of a first portion of the shallow trench isolation region at which the lower end of the nitride film liner is disposed.
