Chip back grinding
WebAug 18, 2024 · Back grinding of wafer with outer rim (BGWOR) is a new method for carrier-less thinning of silicon wafers, and its working principle is shown in Fig. 1. Different from conventional back grinding, the BGWOR process only grinds the inner area of the silicon wafer and leaves a rim (approximately 3–5 mm) on its outer circumference [ 4, 5, 6 ].
