    摘要: A method of manufacturing an integrated circuit structure forms a first opening in a substrate and lines the first opening with a protective liner. The method deposits a material into the first opening and forms a protective material over the substrate. The protective material includes a process control mark and includes a second opening above, and aligned with, the first opening. The method removes the material from the first opening through the second opening in the protective material. The process control mark comprises a recess within the protective material that extends only partially through the protective material, such that portions of the substrate below the process control mark are not affected by the process of removing the material.

    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.
