Method and apparatus for dicing die attach film on a semiconductor wafer
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.
