A semiconductor package for mounting to a printed circuit board (PCB) includes a case comprising a ceramic base, a semiconductor die in the case, a mounting pad under the ceramic base and coupled to the semiconductor die through at least one opening in the ceramic base. The mounting pad includes at least one layer having a coefficient of thermal expansion (CTE) approximately matching a CTE of the ceramic base. The mounting pad includes at least one layer having a low-yield strength of equal to or less than 200 MPa. The mounting pad includes at least one copper layer and at least one molybdenum layer. The semiconductor package also includes a bond pad coupled to another mounting pad under the ceramic base through a conductive slug in the ceramic base.

A semiconductor device includes: first and second semiconductor elements, each of which has first and second electrodes; a first lead mounting the first semiconductor element; a second lead mounting the second semiconductor element; a sealing resin covering the first and second semiconductor elements; a third lead disposed apart from the first and second leads in a y direction, exposed from the sealing resin, and electrically connected to the first electrode of the first semiconductor element; a fifth lead disposed apart from the first and second leads on the opposite side to the third lead, exposed from the sealing resin, and electrically connected to the second electrode of the first semiconductor element; and a sixth lead disposed apart from the first and second leads on the same side as the fifth lead, exposed from the sealing resin, and electrically connected to the second electrode of the second semiconductor element.

A semiconductor device includes a vertical column of wire bonds on substrate contact fingers of the device. Semiconductor dies are mounted on a substrate, and electrically coupled to the substrate such that groups of semiconductor dies may have bond wires extending to the same contact finger on the substrate. By bonding those wires to the contact finger in a vertical column, as opposed to separate, side-by-side wire bonds on the contact finger, an area of the contact finger may be reduced.

A source terminal and a gate terminal are connected to a wiring pattern of the first substrate. A diode is provided under a second substrate such that an anode is connected to a wiring pattern of the second substrate. A plate-like portion of the first electrode is provided between the switching element and the diode, and a linking section of the first electrode connects the plate-like portion and the wiring pattern of the first substrate.

In a described example, a method includes: forming a metal layer on a backside surface of a semiconductor wafer, the semiconductor wafer having semiconductor dies spaced apart by scribe lanes on an active surface of the semiconductor wafer opposite the backside surface; forming a layer with a modulus greater than about 4000 MPa up to about 8000 MPa over the metal layer; mounting the backside of the semiconductor wafer on a first side of a dicing tape having an adhesive; cutting through the semiconductor wafer, the metal layer, and the layer with a modulus greater than about 4000 MPa up to about 8000 MPa along scribe lanes; separating the semiconductor dies from the semiconductor wafer and from one another by stretching the dicing tape, expanding the cuts in the semiconductor wafer along the scribe lanes between the semiconductor dies; and removing the separated semiconductor dies from the dicing tape.
