Method of manufacturing a semiconductor device having a low leakage current










Image Number 17 for United States Patent #6514834.

A field oxide film is provided in the surface of a semiconductor substrate. An interlayer insulating film is provided on the semiconductor substrate so as to cover an active layer. A contact hole exposing the surface of the active layer is provided in the interlayer insulating film. A conductor fills the contact hole so as to be electrically connected to the surface of the active layer. The end portion of the field oxide film has a surface perpendicular with respect to the surface of the semiconductor substrate. As a result, a dynamic random access memory can be obtained which is improved so that leakage current is reduced, which in turn increases a hold time of information.
