  • Patent number: 9189585
    Abstract: A design rule checker that performs a maximum pattern density check in a first intermediary metallization layer that underlies a top metallization layer and a pad opening in an integrated circuit. The maximum pattern density check is performed at least under some circumstances if a modulus of the primary metallization material is less than a modulus of a surrounding dielectric material. The maximum pattern density check verifies that the pattern density within the underlying portion is below a maximum pattern density that depends on the thickness of the access pad. A maximum metal width check may also be performed in this portion.
