Abstract

Microelectronic devices, methods for packaging microelectronic devices, and methods for forming interconnects in microelectronic devices are disclosed herein. In one embodiment, a method comprises providing a microelectronic substrate having a front side and a backside. The substrate has a microelectronic die including an integrated circuit and a terminal operatively coupled to the integrated circuit. The method also includes forming a passage at least partially through the substrate and having an opening at the front side and/or backside of the substrate. The method further includes sealing the opening with a conductive cap that closes one end of the passage while another end of the passage remains open. The method then includes filling the passage with a conductive material.
