摘要: A semiconductor wafer having crossing sets of parallel grooves in one face is broken into dice by placing the wafer with its scribed face down on a sheet of stretchable material to which the wafer adheres. A resilient mat is disposed under the stretchable sheet. A roller is moved over the upper face of the wafer and applies pressure along the grooves to break the wafer into strips. The sheet is then stretched to move the strips apart while keeping the scribed grooves in alignment. The roller then passes over the strips and applies pressure along the aligned scribed grooves which causes the strips to be broken into dice.
