An inductive-coupled plasma apparatus employs a shield to reduce sputter contamination. A method for manufacturing the shield is included. An apparatus for generating a high-density plasma includes a process chamber having a dielectric window located along a plane, a coil located outside the process chamber proximate to the dielectric window and substantially parallel to the plane, and a shield located between the coil and the dielectric window. The shield has multiple openings, wherein the multiple openings of the shield are disposed at locations corresponding to areas between the turns of the coil.

A plasma process apparatus having a plasma chamber with in situ monitoring, a monitoring method, and a method for in situ cleaning a plasma chamber. The apparatus includes a sampling manifold which induces flow of a sample gas from a plasma chamber through the manifold. A gas analyzer analyzes the sample gas flowing through the sampling manifold. The in situ monitoring method monitors an initial gas to establish background levels, and bakes the apparatus to reduce contaminants, if necessary. The monitoring method then monitors a process reaction and, after unloading a wafer and discharging a waste gas, monitors an in situ cleaning reaction. Monitoring involves inducing flow of a gas from the plasma chamber through the sampling manifold, and then analyzing the gas in the manifold with a gas analyzer. The cleaning method includes using a mixture of sulfur hexafluoride and chlorine to clean the plasma chamber after etching a polysilicon layer.

A metallization process for manufacturing semiconductor devices and a system that uses the same that minimizes corrosion failures in aluminum patterns. The process for the metal pattern formation is carried out by loading a semiconductor wafer into an etching chamber, the semiconductor wafer having a photoresist pattern formed over a metal material layer, stabilizing the environment in the etching chamber, main-etching the metal material layer to the etch-end point by using the photoresist pattern as an etch mask while supplying etching gas containing chlorine (Cl ) into the etching chamber, over-etching the metal material layer for a certain period of time over the etch-end point so as to form metal patterns, purging the etching chamber after the over-etching step, and unloading the wafer from the etching chamber. The pressure in the transfer module is optimized, and the load lock chamber is continuously purged.

A dielectric window of a dry etching apparatus for manufacturing semiconductor devices is shaped so that areas of high density plasma in the etching apparatus correspond to portions of the dielectric window further away from the wafer and areas of lower density plasma correspond to portions of the dielectric window closer to the wafer. For example, the dielectric window may be curve inwards at its center in a concave-shape.
