20090020196 | Cold Rolled Steel Sheet Having Aging Resistance and Superior Formability, and Process for Producing the Same - A cold rolled steel sheet, and a method of manufacturing the same, designed to have aging resistance and excellent formability suitable for use in automobile bodies, electronic appliances, and the like. The cold rolled steel sheet comprises in weight %: 0.003% or less of C, 0.003˜0.03% of S, 0.01˜0.1% of Al, 0.02% or less of N, 0.2% or less of P, at least one of 0.03˜0.2% of Mn and 0.005˜0.2% of Cu, and a balance of Fe and other unavoidable impurities. When the steel sheet comprises one of Mn and Cu, the composition of Mn, Cu, and S satisfies at least one relationship: 0.58*Mn/S≦10 and 1≦0.5*Cu/S≦10, and when the steel sheet comprises both Mn and Cu, the composition of Mn, Cu, and S satisfies the relationship: Mn+Cu≦0.3 and 2≦0.5*(Mn+Cu)/S≦20. Participates of MnS, CuS, and (Mn, Cu)S in the steel sheet have an average size of 0.2 μm or less. Since carbon content in a solid solution state in a crystal grain is controlled by fine precipitates of MnS, CuS, or (Mn, Cu)S, the steel sheet has enhanced aging resistance and formability, and has excellent yield strength and strength-ductility. | 01-22-2009 |

20080283087 | DRY CLEANING METHOD OF SEMICONDUCTOR MANUFACTURING APPARATUS HAVING MULTI-LIFTER - A dry cleaning method for use in a semiconductor manufacturing apparatus having a multi-lifter includes checking whether it is a dry cleaning period, and when it is determined to be a dry cleaning period then checking whether a wafer completed for a process has been returned from an electrostatic chuck to the outside of the semiconductor manufacturing apparatus. The method further includes raising an electrostatic chuck cathode part when the wafer has been returned from the electrostatic chuck to the outside of the semiconductor manufacturing apparatus, and forming plasma after raising the electrostatic chuck cathode part, and performing a dry cleaning process. | 11-20-2008 |
