1. A semiconductor device comprising:
a first cell, wherein the first cell comprises:
a first functional feature,
a first sensitivity region, and
at least one anchor node, wherein each of the at least one anchor node is different from the first functional feature, and a number of anchor nodes of the at least one anchor node linked to the first functional feature is based on a position of the first functional feature relative to the first sensitivity region; and
a second cell abutting the first cell, wherein the second cell comprises:
a second functional feature, wherein the second functional feature satisfies a minimum spacing requirement with respect to the first functional feature.
