Dicing of GAN Wafer

GAN 웨이퍼의 다이싱

The dicing is a process of gaining chip from a wafer. It is done by some mechanism to lengthwise and crosswise. Here, it is focused on measuring a depth of the wafer hefore a process of the dicing. First of all, it checks a precise outer position for the wafer on table to gain the chip. Second, the xafer should he lined after Imowing how much depth, it is in out of the outer position of the wafer. Here suggests that there are a composition of mechanical system, how to measure a depth out of scriber axis, a result from testing.
