Abstract

Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip comprising a stilted pad structure. A wire underlies a semiconductor substrate on a frontside of the semiconductor substrate. Further, a trench isolation structure extends into the frontside of the semiconductor substrate. The stilted pad structure is inset into a backside of the semiconductor substrate that is opposite the frontside. The stilted pad structure comprises a pad body and a pad protrusion. The pad protrusion underlies the pad body and protrudes from the pad body, through a portion of the semiconductor substrate and the trench isolation structure, towards the wire. The pad body overlies the portion of the semiconductor substrate and is separated from the trench isolation structure by the portion of the semiconductor substrate.
