Abstract: A semiconductor device having monolithic conductive columns, and associated systems and methods, are disclosed herein. The semiconductor device can include a semiconductor die and a molding material. The semiconductor die may have a semiconductor substrate, a conductive pad, an opening, a non-conductive liner, and a plug of non-conductive material. The conductive pad may be at a surface of the semiconductor substrate. The opening may extend through the semiconductor substrate from the conductive pad to a second surface and define a side wall. The liner may coat the side wall and the plug may fill the opening. A second opening may be formed through the semiconductor device and the opening and a conductive material plated therein. The molding material may be laterally adjacent to the semiconductor die.
