Semiconductor substrates with unitary vias and via terminals, and associated systems and methods are disclosed. A representative system in accordance with a particular embodiment includes a semiconductor substrate having an opening that includes a generally cylindrical portion with a generally smooth, uniform surface. The opening also includes a terminal portion extending transversely to the cylindrical portion and intersecting. A single, uniform, homogeneous volume of conductive material is disposed in both the cylindrical portion and the terminal portion of the opening, the conductive material forming a conductive path in the cylindrical portion and at least a portion of a conductive terminal in the terminal portion. The conductive terminal has a cross-section with generally flat walls aligned with crystal planes of the semiconductor substrate material. The conductive terminal projects away from the semiconductor substrate. |

1. A semiconductor assembly, comprising:
a semiconductor substrate including a substrate material having a first major surface, a second major surface, and an opening extending from the first major surface to the second major surface, the opening including a generally cylindrical portion extending generally normal to the first major surface and a terminal portion extending transverse to the cylindrical portion and intersecting the second major surface, the terminal portion having a width generally parallel to the plane of the first major surface that is greater than a corresponding width of the cylindrical portion; and a homogeneous volume of conductive material disposed in both the cylindrical portion and the terminal portion of the opening, the conductive material forming a conductive path in the cylindrical portion and at least a portion of a conductive terminal in the terminal portion,
wherein the conductive terminal has a cross-section with generally flat walls, the cross-section being taken in a plane normal to the second major surface,wherein the conductive terminal projects outwardly away from the second major surface, andwherein the conductive terminal has a first cross-sectional width in a first plane that generally corresponds to the second major surface of the semiconductor substrate, and a second cross-sectional width in a second plane that is generally parallel to the first plane and positioned beyond an outermost surface of the semiconductor substrate, the second cross-sectional width being greater than the first cross-sectional width. |
