Semiconductor dies formed on a wafer may be picked from the wafer with little or no stress, thus preventing cracking and damage to the semiconductor dies. A die attach film (DAF) layer is laminated onto an inactive surface of the wafer and the DAF layer is cut in the outline of the dies. The inactive surface of the wafer may then be supported on a vacuum chuck without using a dicing tape, and dies transferred from the wafer using a pick and place robot.
