Patent ID: 6885088

Claim:
An electrically conductive leadframe for a semiconductor package, the leadframe having a front face end a rear face, and the leadframe being holdable, between two parts of a mold for the injection molding of an encapsulation material which delimits at least one cavity, in a position such that the rear face is in contact with a bearing surface of part of the mold, the leadframe comprising: a central platform; a peripheral part adjacent the central platform; at least one perforation defining, between the central platform and the peripheral part, first radiating elongate leads having outer and inner ends connected to the peripheral part and to the platform, respectively, and second radiating elongate leads having outer ends connected to the peripheral part and inner ends positioned a certain distance from the platform; and at least one recess formed in the platform on the rear face that comes into contact with the bearing surface of the mold, and at a certain distance from a periphery of the platform.
