Implementations of a semiconductor package may include two or more die, each of the two more die coupled to a metal layer at a drain of each of the two more die, the two or more die and each metal layer arranged in two parallel planes; a first interconnect layer coupled at a source of each of the two more die; a second interconnect layer coupled to a gate of each of the two or more die and to a gate package contact through one or more vias; and an encapsulant that encapsulates the two or more die and at least a portion of the first interconnect layer, each metal layer, and the second interconnect layer.

A semiconductor device has a leadframe and a first electrical component disposed over the leadframe. A clip bond is disposed over the first electrical component. The clip bond has a plurality of recesses each having a different depth. A first recess is proximate to a first distal end of the first electrical component, and a second recess is proximate to a second distal end of the first electrical component opposite the first distal end of the first electrical component. A depth of the first recess is different from a depth of the second recess. A third recess is over a surface of the first electrical component. A depth of the third recess is different from the depth of the first recess and the depth of the second recess. A second electrical component is disposed over the leadframe. The clip bond extends over the second electrical component.

An electronic device includes a substrate having first and second conductive traces, a semiconductor die having a transistor with a first terminal and a second terminal, and first and second metal clips. The first metal clip has a first end portion coupled to the first terminal of the transistor, and a second end portion coupled to the first conductive trace of the substrate. The second metal clip has a first end portion coupled to the second terminal of the transistor and a second end portion coupled to the second conductive trace of the substrate, and a middle portion of the second metal clip is spaced apart from and at least partially overlying a portion of the first metal clip.

A semiconductor device includes a first die pad having a main surface, a second die pad having a second main surface, a first switching element connected to the first main surface, a second switching element connected to the second main surface, a first connecting member connecting the first main surface electrode of the first switching element to the second die pad, an encapsulation resin encapsulating the first switching element, the second switching element, the first die pad, the second die pad, and the first connecting member, and leads projecting out of one of the resin side surfaces of the encapsulation resin.

A variety of footed and leadless semiconductor packages, with either exposed or isolated die pads, are described. Some of the packages have leads with highly coplanar feet that protrude from a plastic body, facilitating mounting the packages on printed circuit boards using wave-soldering techniques.

A semiconductor package includes a transistor chip having first and second opposite facing sides. The semiconductor transistor chip includes a first load electrode and a second load electrode on the first side. The package includes a carrier facing the second side of the chip, a first terminal post laterally beside the transistor chip and a second terminal post laterally beside the transistor chip. The second terminal post is a part of the carrier or physically connects to the carrier. A first clip connects the first load electrode to the first terminal post. A second clip connects the second load electrode to the second terminal post. An upper surface of the first terminal post and an upper surface of the second terminal post are arranged at different levels of height. The first clip and the second clip are of same shape.

A semiconductor device includes a first lead including a base portion, a semiconductor element mounted on one side in a thickness direction of the base portion and having a first electrode disposed on the one side in the thickness direction and a second electrode disposed on the other side in the thickness direction, a second lead spaced apart from the base portion in a first direction orthogonal to the thickness direction, a first conductive member including a first portion bonded to the first electrode and a second portion bonded to the second lead and electrically connected to the first electrode and the second lead, a first bonding layer interposed between, and bonded to the base portion and the second electrode, and a second bonding layer interposed between, and bonded to the first electrode and the first portion. The first bonding layer includes a sintered metal.

A electrical connection element includes a planar mating surface adapted for mating with a metal bonding surface, a rim that forms an enclosed shape around the planar mating surface, and a plurality of outgassing grooves formed in the planar mating surface, wherein each of the outgassing grooves comprises a proximal end that is spaced apart from the rim and a distal end that intersects the rim, and wherein a cross-sectional area of each of the outgassing grooves increases along a lengthwise direction going from the proximal end to the distal end.
