  • Publication number: 20120216396
    Abstract: A system is disclosed for separating a semiconductor die from a tape to which the die is affixed during the wafer dicing process. The system includes a pick-up arm for positioning a vacuum tip over a semiconductor die to be removed. The vacuum tip includes a non-uniform array of vacuum holes to grip the semiconductor wafer.

  • Publication number: 20120145332
    Abstract: A system is disclosed for ejecting a semiconductor die from a tape to which the die is affixed during the wafer dicing process. In embodiments, the system includes an ejector tool including a support table, ejector pins and a pick-up arm. The support table is connected to a vacuum source for creating a negative pressure at an interface between the tape and support table. The support table further includes an aperture with one or more chamfered sidewalls. The vacuum source is connected to the aperture so that, upon placement of the tape on the support table with a die centered over the aperture, the vacuum source pulls a portion of the tape around the edges of the semiconductor die away from the die and into the space created by the chamfered edges.

  • Publication number: 20090325321
    Abstract: A method of forming a semiconductor card. A semiconductor package having a damaged controller die is reclaimed. The reclaim process includes severing the electrical connections between the controller die and the semiconductor package substrate without exposing the passive component. In one embodiment, the cutting tool comprises a saw blade. An electrically insulating material is deposited over the exposed bond wires to complete the reclaim process. The reclaimed package and a new controller die are affixed to a second substrate to electrically couple the memory die of the reclaimed package with the new controller die—forming a new package. The new package is encapsulated to form a new memory card.
