Machining of brittle materials using precision crack-off

At present, a high wasteful and time-consuming method is widely used in silicon fabrication industry for slicing silicon wafers. To minimize the cost as well as shorten lead time, a new fabrication method should be brought out. The objective of this project is to verify and develop precision crac...
