Abstract:
1. A method for manufacturing a plurality of semiconductor device package dies, comprising: a) forming a plurality of semiconductor device dies in a common device substrate, wherein each semiconductor device die includes one or more device regions formed within the device substrate proximate a front surface of the device substrate and a device region formed within the device substrate proximate a back surface of the device substrate; b) forming a back conductive layer on the back surface of the device substrate, the back conductive layer being electrically connected to the device region formed within the device substrate proximate the back surface; c) bonding a support substrate to the back surface; d) dividing the device substrate into a plurality of device die by removing device substrate material between adjacent die leaving the plurality of device die attached to the support substrate and defining sidewalls of a device substrate portion of each device die; and e) forming one or more conductive extensions on one or more corresponding sidewalls of the device substrate portion of each device die and extending to a portion of the front surface of the device die, wherein the one or more conductive extensions are in electrical contact with the back conductive layer.
