Abstract
Etching in combination with other processing techniques is used to facilitate alignment of an optical die in an optical system. The optical dies are formed on a wafer level and need to be singulated for use in the optical system. The formation of a precise edge from etching allows more accurate alignment of the optical die in the optical system. The other processing techniques include dicing, sawing, cleaving, breaking and thinning.
