    摘要: A process and structure for enabling the creation of reliable electrical through-via connections in a semiconductor substrate and a process for filling vias. Problems associated with under etch, over etch and flaring of deep Si RIE etched through-vias are mitigated, thereby vastly improving the integrity of the insulation and metallization layers used to convert the through-vias into highly conductive pathways across the Si wafer thickness. By using an insulating collar structure in the substrate in one case and by filling the via in accordance with the invention in another case, whole wafer yield of electrically conductive through vias is greatly enhanced.

    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.
