摘要:
An isolation which is higher in a stepwise manner than an active area of a silicon substrate is formed. On the active area, an FET including a gate oxide film, a gate electrode, a gate protection film, sidewalls and the like is formed. An insulating film is deposited on the entire top surface of the substrate, and a resist film for exposing an area stretching over the active area, a part of the isolation and the gate protection film is formed on the insulating film. There is no need to provide an alignment margin for avoiding interference with the isolation and the like to a region where a connection hole is formed. Since the isolation is higher in a stepwise manner than the active area, the isolation is prevented from being removed by over-etch in the formation of a connection hole to come in contact with a portion where an impurity concentration is low in the active area. In this manner, the integration of a semiconductor device can be improved and an area occupied by the semiconductor device can be decreased without causing degradation of junction voltage resistance and increase of a junction leakage current in the semiconductor device.

A method of manufacturing semiconductor devices, which realizes miniaturization, a higher aspect ratio of a via hole, a higher yield and reliability, and a high degree of controllability, by completely filling the via hole by performing heat treatment on an electrically conductive thin film in a vacuum atmosphere. The method involves extending an electrically conductive layer into an electrically insulating layer arranged on the electrically conductive layer including the steps of forming an electrically conductive film on a side wall of a via hole extending in the electrically insulating layer from the electrically conductive layer toward the outside of the electrically insulating layer, and heating the electrically conductive film and the electrically conductive layer so that the electrically conductive film flows into the via hole and the electrically conductive layer projects into the via hole.

With keeping an atmosphere including oxygen within a chamber and with a wafer kept at a low temperature, plasma generated within the chamber is biased toward the wafer, and the wafer is subjected to the plasma. A semiconductor layer exposed on the wafer is oxidized into an oxide film. Thus, an oxide film can be formed even at room temperature differently from thermal oxidation. This oxidation is applicable to recovery of an implantation protection insulating film having been etched in cleaning a photoresist film, relaxation of a step formed between polysilicon films, relaxation of a step formed within trench and the like. Also, before removing a photoresist film used for forming a gate electrode including a metal, a contamination protection film can be formed by this oxidation with the photoresist film kept.
