Abstract:
1. A method of making a semiconductor substrate, the method comprising: providing at least one semiconductor die having an active surface and a back surface, the at least one semiconductor die defining at least one via having a substantially uniform cross section therethrough extending from the active surface to the back surface thereof; disposing conductive material in the at least one via to substantially extend therethrough from the active surface to the back surface of the at least one semiconductor die wherein the conductive material completely fills the at least one via; forming at least one electrically conductive redistribution line on the active surface of the at least one semiconductor die in electrical communication with the conductive material of the at least one via and extending to a predetermined location on the active surface of the at least one semiconductor die remote from the location of the at least one via; and forming at least one electrically conductive redistribution line on the back surface of the at least one semiconductor die in electrical communication with the conductive material of the at least one via and extending to a predetermined location on the back surface of the at least one semiconductor die remote from the location of the at least one via.
