Abstract
Methods for forming interconnects in microfeature workpieces, and microfeature workpieces having such interconnects are disclosed herein. The microfeature workpieces may have a terminal and a substrate with a first side carrying the terminal and a second side opposite the first side. In one embodiment, a method includes (a) constructing an electrically conductive interconnect extending from the terminal to at least an intermediate depth in the substrate with the interconnect electrically connected to the terminal, and (b) removing material from the second side of the substrate so that a portion of the interconnect projects from the substrate.
