Granted: 1994-02-14
Abstract: The equipment includes a pad masking layer for etching prevention at the lower part of the first insulating film on the lower part of the expected contact area in order to prevent the other conducting layer or plate from etching and being exposed due to the misarrangement of the contact mask in the etching process where forms contact holes on the second insulating film of the expected contact are in the upper part of the first conducting layer.
