摘要： An etching process including plasma pretreatment for generating a polymer layer formed of carbon on a photoresist pattern. The photoresist pattern is treated with plasma that does not contain fluorine radicals and that provides carbon radicals. An etching process is performed on an etching target layer by using the photoresist pattern as an etch mask.

摘要： There are provided a method of forming a fine pattern of a semiconductor device using a silicon germanium sacrificial layer, and a method of forming a self-aligned contact using the same. The method of forming a self-aligned contact of a semiconductor device includes forming a conductive line structure having a conductive material layer, a hard mask layer, and a sidewall spacer on a substrate, and forming a silicon germanium (Si1-xGex) sacrificial layer, which has a height equal to or higher than a height of at least the conductive line structure, on an entire surface of the substrate. Then, a photoresist pattern for defining a contact hole is formed on the sacrificial layer, and the sacrificial layer is dry-etched, thereby forming a contact hole for exposing the substrate. A plurality of contacts for filling the contact hole are formed using polysilicon, and the remained sacrificial layer is wet-etched. Then, the region where the sacrificial layer is removed is filled with silicon oxide, thereby forming a first interlayer insulating layer.

摘要： 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.
