Cleavage Dicing Mechanics in Silicon Wafers
실리콘 웨이퍼의 그리비지 다이싱 역학
Seong-Min Lee, Yeon-Wook Kim이성민, 김연욱
Korean J. Met. Mater.
2019;57(11):689-694. Published online 2019 Nov 5
DOI:
https://doi.org/10.3365/KJMM.2019.57.11.689
Abstract
This article details how effectively dicing damage of silicon wafers can be mechanically minimized by appropriate laser-induced groove formation prior to wafer separation. Various laser dicing factors, such as the laser-control power, the scan rate and the scan number of the laser beam, were estimated to determine the optimum groove.....
