A method for fabricating a semiconductor device and forming an insulating film used therein, includes forming an isolation insulating film on a semiconductor wafer and forming gates, separated by gaps having a predetermined distance, on an active region. Next, a first interlayer dielectric film is deposited to a predetermined thickness on the semiconductor wafer having the gates, so that the gaps between the gates are not completely filled. Then, a sputtering etch is performed entirely on a surface of the first interlayer dielectric film. Thereafter, the first interlayer dielectric film is partially removed through isotropic etching. Next, a second interlayer dielectric film is deposited on the first interlayer dielectric film so that the gaps between the gates are completely filled. According to the above method, a gap between gate patterns can be completely filled without a void by performing sputtering etch on interlayer dielectric films formed on gate patterns, thereby enhancing the reliability of a semiconductor device.

A method for forming a unitary polymeric projection or fastener comprising a thin, strong flexible backing, and a multiplicity of thin spaced hook members projecting from the upper surface of the unitary backing the method generally including extruding a thermoplastic resin through a die plate which die plate is shaped to form a base layer and spaced ridges, ribs or hook elements projecting above a surface of the base layer. When the die forms, the spaced ridges or ribs the cross sectional shape of the hook members are formed by the die plate while the initial hook member thickness is formed by transversely cutting the ridges at spaced locations along their lengths to form discrete cut portions of the ridges. Subsequently longitudinal stretching of the backing layer (in the direction of the ridges on the machine direction) separates these cut portions of the ridges, which cut portion then form spaced apart hook members. The extruded hook members or cut rib hook members are then heat treated resulting in shrinkage of at least a portion of at least the hook head portion thickness by from 5 to 90 percent, preferably 30 to 90 percent.

The invention relates to a processing method for distribution network short circuit fault, in particular to a method for detecting the distribution network short circuit fault and restoring power supply in a non-broken-down section, and capable of achieving feeder line automatic local control.
