    Summary: 雷射開槽雖然解決了傳統鑽石刀切割在品質及良率遇到的問題,但是其設定參數是由雷射功率、雷射頻率、焦距和切割速度所組成,其組合起來的參數並沒有一定的指標可以判斷不同的參數間與雷射開槽品質的關係,尤其是晶圓級晶片尺寸的封裝,因為晶圓級晶片尺寸的封裝是採用先在晶片上就把所有的製程做好,然後再切割成一顆一顆的晶粒,切割完後就是成品,因此在外觀上特別要求,所以雷射的外觀品質上對我們來說是非常重要的一項指標,本論文主要探討雷射開槽參數中不覆蓋率與雷射開槽外觀平整度的關係,從而建立一雷射開槽的最佳化模型。 Since that there is no molding on the die surface and any visual defect of die surface will be critical to die function, it is important that a uniform edge by diamond blade sawing to separate dies in wafer level chip scale package (WLCSP) process, and it is a key index in WLCSP products. Laser grooving is attractive to improve the quality and yield loss issue in diamond blade sawing. However, parameters of laser grooving are depend on laser power, laser frequency, defocus and laser speed, and none of them can be specified independently to control the quality index in WLCSP products die separation processing. The objective of this thesis is focus on the non-overlap rate in laser grooving of WLCSP products, and to develop optimized parameters for laser grooving for WLCSP and its related products.
