• Wafer edge profile creates highstress regions when thinning wafers below 100 μm • Thin grinding of wafers with bumps and other artifacts makes it necessary for a gentle grind to prevent edge chipping and eventual failure • Thin wafers cannot withstand high subsurface damage and need finer abrasive grain wheels to increase wafer

Standard Backgrind Backgrinding Appliions Electronics

Based on the wafer type to be ground, we offer a variety of coarse wheels to suit specific needs. The standard coarse wheel that works on most of the appliions is the Norton Winter #320 wheels. These can be offered in varying hardness for grinding different wafer types. A typical specifiion would be COARSE#3H1BXL9002. Fine Grind

The present invention has an object to provide a manufacturing process of a semiconductor wafer in which improvement on accuracy in a chamfering portion is realized. The manufacturing process of a semiconductor wafer comprises: a slicing step of obtaining a wafer in the shaped of a thin disk by slicing a single crystal ingot a surfacegrinding step of flattening a surface of the wafer

Fine grinding of silicon wafers: designed experiments

Fine grinding of silicon wafers requires using #2000 mesh (3–6 µm grit size) or fi ner diamond wheels. The surfaces to be fi ne ground generally have no damage or very little damage and the surface roughness is 30 nm in Ra [6]. The uniqueness and the special requirements of silicon wafer fi ne grinding process were discussed in the pre
