Abstract:
1. A method for generating a cutting form layout including cutting forms for deleting metal along a current flow direction in an integrated circuit layout, comprising: using a computer, identifying a metal wire in the integrated circuit layout to receive the cutting forms, the metal wire comprising at least one metal wire portion having a portion length edge and portion width edge; inserting with a first orientation a first plurality of preliminary cutting forms within the at least one portion of the metal wire, each of the first plurality of preliminary cutting forms having a width edge, and a length edge longer than the width edge; determining if the width edge of each of the first plurality of preliminary cutting forms is substantially parallel to a width edge of a corresponding portion in which the first plurality of preliminary cutting forms are inserted; removing any of the first plurality of preliminary cutting forms not having a width edge substantially parallel to the width edge of the corresponding metal wire portion; and defining as final cutting forms the first plurality of preliminary cutting forms having width edges determined as substantially parallel to the width edge of the corresponding metal wire portion.
