Abstract:
1. A semiconductor device, comprising: a semiconductor substrate; first and second metallization layers, the second metallization layer being spaced apart from the semiconductor substrate with the first metallization layer therebetween; and a conductive interconnect extending at least partially through the semiconductor substrate, wherein the conductive interconnect includes a first end and a second end opposite the first end, wherein the second metallization layer includes a first portion generally corresponding to the conductive interconnect and a second portion extending laterally from the first portion, and wherein the first end of the conductive interconnect is electrically coupled to the first portion of the second metallization layer, wherein the first end of the conductive interconnect includes a lateral portion that extends laterally to the first portion of the second metallization layer; and wherein the first metallization layer is in electrical contact with the conductive interconnect via the second metallization layer; and wherein the semiconductor substrate includes a first side and a second side; and the semiconductor device includes: the first end of the conductive interconnect is in direct contact with the first portion of the second metallization layer; and a solder ball attached to the second end of the conductive interconnect at the second side of the semiconductor substrate.
