Patent ID: 6967127

Claim:
A method of forming a semiconductor package comprising: providing a semiconductor chip comprising at least a first electrical contact pad and at least a second electrical contact pad disposed on an active surface thereof; providing a leadframe comprising at least a first lead and at least a second lead originating at a first side of said leadframe in a first plane and having substantially similar lengths, said at least a first lead comprising at least a first array offset between inner and outer ends thereof comprising a segment of said at least a first lead that protrudes from said first plane to a second plane, and said at least a second lead comprising at least a second array offset between inner and outer ends thereof comprising a segment of said at least a second lead that protrudes from said first plane to said second plane; attaching said leadframe to said active surface of said semiconductor chip; electrically connecting said at least a first lead to said at least a first electrical contact pad and said at least a second lead to said at least a second electrical contact pad; placing said leadframe and semiconductor chip into a mold cavity with at least a portion of said at least a first array offset and said at least a second array offset in contact with an interior surface of said mold cavity; and introducing a molding compound into said mold cavity to encapsulate said at least a first lead and said at least a second lead and said active surface of said semiconductor chip.
