Abstract: Disclosed herein is a method for etching a face of an object and more particularly a method for etching a rear face of a silicon substrate. The object having a silicon face is positioned so as to be spaced apart from a plasma-generating member by a predetermined interval distance. The plasma-generating member generates arc plasmas to form a plasma region. A reaction gas is allowed to pass through the plasma region to generate radicals having high energies and high densities. The radicals react with the object to etch the face of the object. The face of the object can be rapidly and uniformly etched.

Abstract: A method of manufacturing a contact of a semiconductor device includes a series of pretreatment processes each performed in a plasma pretreatment module. A semiconductor substrate has an interlayer formed on an underlayer of a material containing silicon. A contact hole is formed in the interlayer to expose a surface of the underlayer. Subsequently, the semiconductor substrate is loaded into a plasma pretreatment module. The photoresist pattern is removed by ashing in the plasma pretreatment module. A damaged layer at the surface exposed by the contact hole is then removed in the plasma pretreatment module. Subsequently, the semiconductor substrate is pre-cleaned in the plasma pretreatment module. The semiconductor substrate is then transferred, while in a vacuum, to a deposition module. There, an upper layer is formed on the substrate to fill the contact hole.
