Abstract:
1. A wafer processing system, comprising: a first tool used to change a peripheral edge of a wafer to be subsequently diced along a number of dicing paths oriented in a first direction, wherein the changing includes cutting the peripheral edge along a number of cut lines oriented in a second direction to produce a number of blade entry edge surfaces, with each of the number of blade entry edge surfaces substantially perpendicular to at least one of the number of dicing paths for each of the dicing paths oriented in the first direction; and a second tool used to dice the wafer along the number of dicing paths oriented in the first direction; wherein at least one of the number of cut lines oriented in the second direction is unaligned with at least one of a number of dicing paths oriented in the second direction.
