    摘要: A method for performing grinding includes selecting a target wheel loading for wafer grinding processes, and performing a grinding process on a wafer. With the proceeding of the grinding process, wheel loadings of the grinding process are measured. The grinding process is stopped after the target wheel loading is reached. The method alternatively includes selecting a target reflectivity of wafer grinding processes, and performing a grinding process on a wafer. With a proceeding of the grinding process, reflectivities of a light reflected from a surface of the wafer are measured. The grinding process is stopped after one of the reflectivities reaches the target reflectivity.

    摘要: A bottom chase and a top chase of a molding system form a cavity to house a molding carrier and one or more devices. The molding carrier is placed in a desired location defined by a guiding component. The guiding component may be entirely within the cavity, or extend above a surface of the bottom chase and extend over a contacting edge of the top chase and the bottom chase, so that there is a gap between the edge of the top chase and the edge of the molding carrier which are filled by molding materials to cover the edge of the molding carrier. Releasing components may be associated with the top chase and/or the bottom chase, which may be a plurality of tape roller with a releasing film, or a plurality of vacuum holes within the bottom chase, or a plurality of bottom pins with the bottom chase.
