Abstract:
1. A leadframe device, comprising: a plurality of leads configured for being coupled to bonding pads of a chip; and a plurality of noncurvilinear supporting bars positioned differently from the leads, the supporting bars comprising elongate strips which radially extend from but are not branch-shaped and do not encircle a central region of the device and which have height-dimensions up to but not above apexes of the leadframe device, and the supporting bars being attached to the chip without the supporting bars or any structures integrally formed with the supporting bars contacting or extending over an active region of the chip or a region of the chip that is beneath the active region, behind the active region, or on a side of the chip opposite to the active region, whereby the supporting bars and the bonding pads are directly coupled to a periphery of the chip and heights of the supporting bars do not contribute to the total height of the device.
