  • Publication number: 20140087521
    Abstract: An improved wafer level chip scale packaging technique is described which does not use an encapsulated via to connect between a redirection layer and a pad within the pad ring on the semiconductor die. In an embodiment, a first dielectric layer is formed such that it terminates on each die within the die's pad ring. Tracks are then formed in a conductive layer which contact one of the pads and run over the edge of an opening onto the surface of the first dielectric layer. These tracks may be used to form an electrical connection between the pad and a solder ball.

  • Patent number: 8673743
    Abstract: A wafer is divided by setting the focal point of a laser beam inside the wafer at positions corresponding to division lines, thereby forming modified layers inside the wafer along the division lines. Each modified layer has a thickness ranging from the vicinity of the front side of the wafer to the vicinity of the back side of the wafer. An etching gas or an etching liquid is supplied to the wafer to erode the modified layers, thereby dividing the wafer into individual devices. The modified layers are not crushed, so fine particles are not generated in dividing the wafer. Accordingly, fine particles do not stick to the surface of each device and cause a reduction in quality. Further, since the modified layers are removed by etching, it is possible to prevent a reduction in die strength of each device due to the remainder of the modified layers.

  • Patent number: 8647966
    Abstract: In one aspect of the present invention, a method of sawing a semiconductor wafer will be described. A semiconductor wafer is positioned in a wafer sawing apparatus that includes a sawing blade and a movable support structure that physically supports the semiconductor wafer. The semiconductor wafer is coupled with the support structure with various layers, including a die attach film, an adhesive and a base film. The die attach film is cut with the sawing blade. During the cutting operation, a contact portion of the sawing blade engages one of the layers and moves at least partly in one direction. While the contact portion of the sawing blade engages the layer, the support structure moves in the opposite direction. Various aspects of the present invention relate to arrangements and a wafer sawing apparatus that involve the aforementioned sawing method.
