  • Patent number: 7821112
    Abstract: A semiconductor device having linear zigzag(s) for wire bonding is revealed, primarily comprising a chip, a plurality of leads made of a lead frame and a plurality of bonding wires electrically connecting the chip and the leads. At least one of the leads has a linear zigzag including a first finger and a second finger connected each other in a zigzag form. One end of one of the bonding wire is bonded to a bonding pad on the chip and the other end is selectively bonded to either the first finger or the second finger but not both in a manner that the wire-bonding direction of the bonding wire is parallel to or in a sharp angle with the direction of the connected fingers for easy wire bonding processes. Therefore, the semiconductor device can assemble chips with diverse dimensions or with diverse bonding pads layouts by flexible wire-bonding angles at linear zigzag to avoid electrical short between the adjacent leads.

  • Patent number: 7575957
    Abstract: A leadless semiconductor package mainly includes a plurality of inner leads, a chip pad, a semiconductor chip and a molding compound. A non-conductive ink is filled between every two of the inner leads, and couples the inner leads to the chip pad so as to be in replacement of the conventional tie bars. The semiconductor chip is disposed on the chip pad and electrically connected to the inner leads. Moreover, the molding compound is formed on the inner leads and the non-conductive ink for encapsulating the semiconductor chip. The non-conductive ink prevents the exposed bottom surfaces of the inner leads from contamination by the molding compound without attaching an external tape during molding. Also the inner leads can be in a multi-row arrangement and the chip pad can be disposed in an optional location.
