A method including forming a plurality of dicing channels in a front side of a wafer; the plurality of dicing channels including a depth at least greater than a desired final thickness of the wafer, filling the plurality of dicing channels with a fill material and removing a portion of the wafer from a back side of the wafer until the desired final thickness is achieved, where a portion of the fill material within the plurality of dicing channel is exposed. The method further including depositing a metal layer on the back side of the wafer; removing the fill material from within the plurality of dicing channels to expose the metal layer at a bottom of the plurality of dicing channels, and removing a portion of the metal layer located at the bottom of the plurality of dicing channels.
