The dust cover is composed of an annular projection part(1a) protruded and linearly contacted to the outer periphery of the universal joint shaft, a tube part(1b) placed opposite to the projection part and contacted to the outer periphery of the universal joint shaft to prevent infiltration of dust, and a grease pocket(1c) recessed between the projection part and the tube part and filled with grease for lubrication. The universal joint shaft is rotated actively by spreading grease between the dust cover and the universal joint shaft.

Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to easily and rapidly remove polymers of photoresist and to minimize corrosion of an aluminum line by using an improved cleaning composition. CONSTITUTION: An etch target layer is formed on a substrate. The etch target layer is etched using a photoresist pattern as a mask. At this time, photoresist polymers are generated. The polymers are removed by using a cleaning composition. The cleaning composition includes H2SO4 of 5-15 weight %, hydrogen peroxide of 1-5 weight % or ozone of 0.0001-0.05 weight %, acetic acid of 0.1-5 weight %, ammonium floride of 0.0001-0.5 weight %, and water.
