Process induced sub-surface damage in mechanically

2008-5-28 In the rough grinding process, the brittle grinding mechanism, which is commonly seen in Si, takes place in addition to the ductile grinding. As illustrated in figure 10, when a sharp grit gets into contact with the wafer surface, a stress is applied to the silicon. Since the contact region of a sharp grit is rather small, the stress surpasses the fracture strength of silicon.
