    摘要: A method of fabricating a semiconductor device includes the steps of forming a contact hole in an insulator layer, filling the contact hole by a conductor material, removing the conductor material from the upper major surface of the insulator layer to form a conductive plug such that the conductive plug fills the contact hole, applying an anisotropic etching process upon the insulator layer, such that the anisotropic etching process acts substantially vertically and selectively to the insulator layer, with an etching rate substantially larger than an etching rate for the conducive plug.

    摘要: In a manufacturing method of a semiconductor device, a gate insulating film is grown in an active region. Thereafter, an N-type polysilicon film is formed on the gate insulating film and is patterned so that a gate electrode and a polysilicon electrode are formed. Next, arsenic ions are implanted onto entire faces of the gate and polysilicon electrodes so that a source-drain region is formed on a substrate. An interlayer insulating film is then formed on an entire face of the source-drain region, etc. Thereafter, a contact hole is formed on a drain region in a position in which the drain region partially overlaps the polysilicon electrode. A surface portion of the polysilicon electrode is exposed into the contact hole. Thereafter, phosphoric ions are implanted through the contact hole with the interlayer insulating film as a mask. The implanted ions are thermally processed to activate these implanted ions. Thereafter, metal wiring is formed. Thus, resistance of a common contact having s three-dimensional structure is reduced.
