    • PURPOSE: A method for etching a polysilicon for forming a gate electrode is provided to reduce a tail generated in a bottom part of the gate electrode and to obtain a vertical profile by increasing an out gassing effect according to the reduction of the pattern size. CONSTITUTION: A preventing film of reflection and a polysilicon film are successively etched in an etching chamber by using a photoresist film as a mask. Herein, a certain thickness of the polysilicon film is etched by using 10-100sccm of Cl2 gas, 20-60sccm of SF6 gas, 20-200sccm CF4 gas, or 0-20sccm of HeO2 gas in a pressure for 20-100mTorr and a power for 150-400W. And then, the remained polysilicon film is etched by using 10-100sccm of Cl2 gas and 30-150sccm of HBr gas in the pressure for 75-200mTorr and the power for 50-300W to form a gate electrode(104a). Herein, the side of a top part(B) is 230mm, and the size of a bottom part(A) is 250mm. Therefore, a tail generated in the bottom part of the gate electrode and a polymer are reduced while obtaining a vertical profile.

    • A method for forming a fuse pattern for repairing a bad cell includes forming a metal wiring pattern on a substrate and successively forming an insulating layer on the metal wiring pattern and the substrate. The insulating layer of a region for defining the fuse pattern is etched by using an etching gas including a fluorocarbon-type compound and a fluorosilicate-type compound, which substantially suppresses a generation of by-products. A partially exposed metal layer of the metal wiring pattern is removed to form a fuse. Accordingly, a structure such as a fence is not formed on the residue of insulating layer. Therefore, the removal process for the fence is unnecessary. As a result, the process for forming the fuse is simplified.

    • PURPOSE: A method for manufacturing a semiconductor memory device is provided to improve the yield by preventing damage to a boundary region between an active region and a field oxide layer. CONSTITUTION: A semiconductor substrate(31) is splitted up into the first region for isolating respective devices and the second region which is an active region where devices are formed.
