Method of separating a thin semiconductor die from a wafer

A method of separating a thin die (20, 60) from a support body (72) of a semiconductor wafer (70). The thin die (20, 60) being initially attached to the support body (72) by an attachment mechanism (78, 178). The attachment mechanism may be a plurality of tethers (78, 178). The method may include th...

Zusammenfassung:A method of separating a thin die (20, 60) from a support body (72) of a semiconductor wafer (70). The thin die (20, 60) being initially attached to the support body (72) by an attachment mechanism (78, 178). The attachment mechanism may be a plurality of tethers (78, 178). The method may include the steps of: positioning the thin die (20, 60) above a hole (112); positioning a tip (128) of a handler (120) above the thin die (20, 60); positioning an ejection pin (150) in a spaced apart relationship beneath the thin die (20, 60); moving the tip (128) downward toward the thin die (20, 60) to break the attachment mechanism (78, 178) and clamp the thin die (20, 60) between the tip (128) and the ejection pin (150); and moving the ejection pin (150) upward until the thin die (20, 60) is extracted from the wafer (70).
