    摘要： A semiconductor device has a die mounted on a die paddle that is elevated above and thermally connected via tie bars to a heat sink structure. Heat generated by the die flows from the die to the die paddle to the tie bars to the heat sink structure and then to either the external environment or to an external heat sink. By elevating the die/paddle sub-assembly above the heat sink structure, the packaged device is less susceptible to delamination between the die and die attach adhesive and/or the die attach adhesive and the die paddle. An optional heat sink ring can surround the die paddle.

    摘要： A lead frame for a semiconductor package has a flag to which a semiconductor die is mounted. Tie bars are coupled to the flag. There is a first set of leads and each first set lead in the first set of leads has a first set lead parallel length and a first set lead tapered length. The first set lead parallel length of each first set lead has a constant width and edges that are parallel to edges of all other first set lead parallel lengths. A free end region of the first set lead tapered length of each first set lead provides a first set lead bond target region. There is a second set of leads disposed between a first one of the tie bars and the first set of leads. Each second set lead, in the second set of leads, has a second set lead parallel length and a second set lead tapered length. The second set lead parallel length of each second set lead has a constant width and edges that are parallel to edges of all other second set lead parallel lengths in the second set of leads and also parallel to the edges of first set lead parallel lengths. At least one second set lead has an extension length extending inwardly from the second set lead tapered length, the extension length has a constant width and provides a second set lead bond target region. Wire bond leads electrically couple both the first set lead bond target region and second set lead bond target region to respective die external electrical connection pads on a surface of the die and a package body encloses the die.

    摘要： A method for reducing a surface area of a pad limited semiconductor die layout includes choosing an outer die pad row from a group of outer die pad rows on the semiconductor die, each of the outer die pad rows being adjacent an edge of the semiconductor die. Next, the method performs selecting, from the outer die pad row, a common die pad group with die pads that are arranged to be electrically connected to an external connection pad. The method then performs repositioning a subgroup of the common die pad group on an inner die pad row, the inner pad row being adjacent the outer die pad row. After he repositioning there is performed a step of adjusting positions of at least some of the remaining pads in the outer die pad row thereby reducing an overall length of the outer die pad row. The method then provides for repeating the above steps until the surface area of a pad limited semiconductor die cannot be reduced any further by the step of adjusting positions or until every common die pad group, on every one of the outer die pad rows, has been selected by the selecting step.
