Abstract:
A method for measuring bridge induced by mask layout amendment, comprising:providing a mask, said mask having a layout which comprises: a conductor line pattern; a plurality of gate patterns, each said gate pattern being separated with other said gate patterns, gate patterns being connected with said conductor line pattern; and a plurality of contact pattern groups, each said contact pattern group being separated with other said contact pattern groups and being corresponding to one said gate pattern, each said contact pattern group at least having a plurality of contact patterns which at least surrounds one terminal of said corresponding gate pattern and which do not contact with said conductor line; amending said layout; transferring amended said layout into a substrate, so that a conductor line, a plurality of gates and a plurality of contact groups are formed in and on said substrate; electrically coupling said contact groups with a terminal; and applying an electrical signal into said conductor line and measuring whether said electrical signal appears at said terminal.
