摘要： A dry-etching method for working SiO.sub.2, phospho-silicate glass, Si, Mo, W, Cr, TiW, Si.sub.3 N.sub.4 or the like by the use of a glow discharge plasma involves the steps of introducing He, Ar, N.sub.2, O.sub.2 or a mixed gas thereof into a reaction chamber from the outside; and effecting the plasma discharge in the reaction chamber so that a reactive gas is liberated from a high molecular resin material arranged in the reaction chamber and containing fluorine atoms. The dry-etching method requires and uses no expensive gas containing a fluorocarbon, but has sufficient etching rate and selectivity.

摘要： A wafer flattening process designed to flatten the entire surface of the wafer to a higher precision by projecting the fall in the etching rate at the outer peripheral portion of the wafer and forming the outer peripheral portion of the wafer thinner in advance before plasma etching the entire surface of the wafer, a wafer flattening system, and a wafer flattened by the same. The wafer flattening system is provided with a CMP apparatus 1 and a plasma etching apparatus 2 are provided. The outer peripheral portion Wb of a wafer W held by a carrier 11 is polished thinner than an inside portion Wc of the wafer W by the CMP apparatus 1 having a platen 10 formed with a recessed surface. Specifically, it is polished so that the maximum thickness at the outer peripheral portion Wb of the wafer W becomes not more than the minimum thickness at the inside portion Wc. Suitably thereafter, the plasma etching apparatus 2 locally etches the surface Wa of the wafer W to obtain a wafer W with a high flatness without any projecting portion at the outer peripheral portion Wb.

摘要： A wafer flattening system is provided to consecutively and automatically remove the natural oxide film from a wafer and flatten and smooth the wafer so as to improve the surface roughness of the wafer and improve the work efficiency. A step of immersing the wafer in an aqueous solution of hydrofluoric acid of a natural oxide film removing device is performed so as to remove the natural oxide film, then followed by a step of locally etching the surface of the wafer at a local etching apparatus by an activated species gas produced from SF6 gas to flatten the surface. Then, a step of giving a mirror finish to the wafer surface by a CMP apparatus is performed to smooth it. It is also possible to perform the step of removal of the natural oxide film by spraying the entire surface of the wafer by an activated species gas produced from a mixed gas of CF4 gas and H2 gas and possible to perform the step of smoothing by spraying the entire surface of the wafer by an activated species gas produced from a mixed gas of CF4 gas and O2 gas.
