摘要： Embodiments of the invention provide an integrated circuit (IC) having reduced through silicon via (TSV)-induced stresses and related IC design structures and methods. In one embodiment, the invention includes a method of designing an integrated circuit (IC) having reduced substrate stress, the method including: placing in an IC design file a plurality of through silicon via (TSV) placeholder cells, each placeholder cell having an undefined TSV orientation; replacing a first portion of the plurality of TSV placeholder cells with a first group of TSV cells having a first orientation; and replacing a second portion of the plurality of TSV placeholder cells with a second group of TSV cells having a second orientation substantially perpendicular to the first orientation, wherein TSV cells having the first orientation and TSV cells having the second orientation are interspersed to reduce a TSV-induced stress in an IC substrate.
