Abstract

In certain aspects, a semiconductor device includes a first semiconductor layer, a first semiconductor structure formed on the first semiconductor layer including a main chip region, and seal ring discontinuous contact structures formed in a seal ring region enclosing the main chip region. Each seal ring discontinuous contact structure includes a seal ring body portion and a through silicon contact (TSC) portion penetrating through the first semiconductor layer and coupled to the seal ring body portion.
