    摘要: A method for forming a metal contact in a semiconductor device includes forming bit lines over a substrate defined into a cell region and a peripheral region, forming a first inter-layer dielectric (ILD) layer over the bit lines, forming a first etch stop layer over the first ILD layer, forming a capacitor in the cell region, forming a second etch stop layer over the substrate after the capacitor is formed, forming a second ILD layer over the second etch stop layer, performing a first etching process to etch portions of the second ILD layer and the second etch stop layer to thereby form first metal contact holes exposing the first etch stop layer, and performing a second etching process to etch portions of the first etch stop layer and the first ILD layer to thereby form second metal contact holes exposing the bit lines.

    摘要: Disclosed is an apparatus for generating low-temp plasma at atmospheric pressure, comprising: a couple of electrodes facing each other at a distance, one of them being connected to a power supply, the other being grounded; a couple of dielectrics with a thickness of 25 &mgr;m-10 mm, positioned on the facing surfaces of the electrodes in such a way as to face each other, one of them having at least one discharge gap therein; and a conductor electrode having at least one tip positioned within the discharge gap, in which an electric field is applied at an intensity of 1-100 KV/cm through the power supply across the electrodes by use of a pulse direct current or an alternating current in a frequency bandwidth of 50 Hz-10 GHz while a reaction gas is fed between the electrodes, so as to induce a hollow cathode discharge, a capillary discharge or the high accumulation of charges from the discharge gap.
