Patent ID: 8853834

Claim:
A leadframe-type semiconductor package comprising: a leadframe including a plurality of signal leads, at least a ground lead, and a die attach pad, wherein the die attach pad is coupled to at least a first metal tie bar; a chip disposed on the die attach pad and electrically connected to the signal leads; an encapsulant encapsulating the chip, wherein the encapsulant has a first surface, a second surface and further has two opposing lead-extending sides and two opposing leadless sides between the first surface and the second surface; and an Electromagnetic Interference (EMI) shielding layer covering the first surface of the encapsulant and the leadless sides; wherein the signal leads have a plurality of first external lead portions extending from the lead-extending sides, the first tie bar has a first cut end aligned with and exposed on one of the leadless sides, the ground lead has a second external lead portion extending from one of the lead-extending sides and a second cut end aligned with and exposed on one of the leadless sides, through the covering of the EMI shielding layer to electrically connect the first cut end with the second cut end, the die attach pad has ground potential through external electrical connection outside the encapsulant.
