Abstract:
1. A method for peeling semiconductor chips from tape, comprising: providing a nose on a housing, the nose having transverse dimensions smaller than the transverse dimensions of a target chip; providing apertures through the nose from the housing; providing vacuum channels on the nose having an X pattern and connected to at least some of the apertures; providing vacuum ports in the housing adjacent the nose; providing vacuum channels on the housing having a ring pattern with arms extending therefrom and connected to at least some of the vacuum ports; providing a vacuum source that controllably connects to the apertures and the vacuum ports; positioning the nose adjacent a tape attached on the opposite side thereof to the target chip; and applying vacuum to attract the tape against the nose and the adjacent portions of the housing to peel the tape from the peripheral edges of the target chip while supporting the tape in the center of the target chip.
