Edge chipping of silicon wafers in diamond grinding
Rotating grinding is the most commonly used technique in silicon wafer thinning, while it will induce edge chipping as wafer thickness decrease. The experimental results demonstrated that different sawing processes present different material removal modes and edge quality, which results in the cutting force of ultrasonic assisted sawingThe grinding force is a determinative factor on the grinding quality. There is no theoretical model of grinding force in silicon wafer self-rotating grinding yet. To develop the grinding force model, the grinding mechanism of silicon wafer self-rotating grinding was studied, and the grinding force was divided into a sliding force and a chip formation force.硅晶圆磨削减薄工艺的磨削力模型 cstam.cn
