    摘要: An assembly including a main wafer having a body with a front side and a back side, and a handler wafer, is obtained. The main wafer has a plurality of blind electrical vias terminating above the back side. The blind electrical vias have conductive cores with surrounding insulator adjacent side and end regions of the cores. The handler wafer is secured to the front side of the body of the main wafer. An additional step includes exposing the blind electrical vias on the back side. The blind electrical vias are exposed to various heights across the back side. Another step involves applying a first chemical mechanical polish process to the back side, to open any of the surrounding insulator adjacent the end regions of the cores remaining after the exposing step, and to co-planarize the via conductive cores, the surrounding insulator adjacent the side regions of the cores, and the body of the main wafer. Further steps include etching the back side to produce a uniform standoff height of each of the vias across the back side; depositing a dielectric across the back side; and applying a second chemical mechanical polish process to the back side, to open the dielectric only adjacent the conductive cores of the vias.

    摘要: A method includes receiving at least one wafer having a front side and a backside, where the front side has a plurality of integrated circuit chips thereon. The backside of the wafer is thinned, a pattern of material is removed from the backside of the wafer to form a plurality of dicing trenches. Each of the dicing trenches are positioned opposite a location on the front side of the wafer that corresponds to edges of each of the plurality of chips. The dicing trenches are filled with a filler material and a dicing support is attached to a front side of the wafer. The filler material is removed from the dicing trenches, and a force is applied to the dicing support to separate each of the plurality of chips on the wafer from each other along the dicing trenches.
