Abstract:
A method of singulating no-lead semiconductor devices assembled on a lead frame array, includes performing first and second laser scribing operations first and second sides of saw streets of the lead frame array, and then cutting between the first and second scribe lines, formed by the scribing operations, with a saw. The finished devices include a notch, formed by the scribing operations, at exposed portions of the device leads. Scribing the saw streets before cutting prevents smearing of the leads and the formation of burrs on the leads.

Claim (Index 1):
A no-leads semiconductor device, comprising:\n an integrated circuit (IC) die; a plurality of lead fingers spaced from and projecting outwardly from at least one side of the IC die, wherein electrodes of the IC die are electrically connected to proximal portions of respective ones of the lead fingers; a housing encasing the IC die, the lead fingers, and connections therebetween, wherein the housing has opposing top and bottom surfaces, and side surfaces that extend between the top and bottom surfaces, wherein distal ends of the lead fingers are exposed at the bottom and at least one of the side surfaces of the housing, and the exposed distal ends are flush with the bottom surface, wherein an exposed portion of each of the lead fingers includes a first notch that offsets a portion of the distal ends of the lead fingers from the at least one of the side surfaces; and a second notch formed in the exposed portions of the lead fingers and the housing, and wherein the first and second notches extend along the at least one of the side surfaces of the housing.
