A semiconductor device package includes a semiconductor die having two largest dimensions that define a major plane, a packaging material enclosing the semiconductor die, a plurality of contacts on a first exterior surface of the semiconductor device package that is parallel to the major plane, the first exterior surface defining a bottom of the semiconductor device package, and a pedestal of semiconductor material above the semiconductor die in a thermally-conductive, electrically non-conductive relationship with the semiconductor die. The semiconductor material of the pedestal may be doped to provide electromagnetic shielding of the semiconductor die.

A chip is mounted on a surface of the substrate, and the thermally conductive cover is disposed on a side that is of the chip and that is away from the substrate. There is a filling area on a surface that is of the thermally conductive cover and that faces the substrate, and the filling area is opposite to the chip. There is an accommodation cavity whose opening faces the substrate in the filling area. A thermal interface material layer is filled between the chip and a bottom surface of the accommodation cavity. Between an opening edge of the accommodation cavity and the substrate, there is a first gap connected to the accommodation cavity. The filling material encircles a side surface of the thermal interface material layer, so that the filling material separates the side surface of the thermal interface material layer from air.

An electronic package is provided in the present disclosure. The electronic package comprises: a heat spreading component; a first electronic component disposed on the heat spreading component; and a second electronic component disposed on the first electronic component, wherein the second electronic component comprises an interconnection structure passing through the second electronic component and electrically connecting the first electronic component. In this way, through the use of the interconnection structure, the heat dissipation of the electronic components in the package can be improved. Also, through the use of the encapsulant, the stacked electronic components can be protected by the encapsulant so as to avoid being damaged.

Methods, systems, apparatus, and articles of manufacture to control load distribution of integrated circuit packages are disclosed. An example apparatus includes a heatsink, a base of the heatsink to be thermally coupled to a semiconductor device, and a rigid plate to be coupled to the semiconductor device and the base of the heatsink, the rigid plate stiffer than the base, the rigid plate distinct from a bolster plate to which the heatsink is to be coupled.

Provided is an evaporator stack. The evaporator stack may be used in power-dense electronic assemblies. The evaporator stack includes a lower floor including at least one mounded portion, and an enclosure surrounding the lower floor, wherein a height of the enclosure is greater than a height of the at least one mounded portion, the at least one mounded portion extending between two walls of the enclosure.

In one form, a method of manufacturing a circuit device comprises providing a lead frame comprising a plurality of leads, each comprising an island portion, a bonding portion elevated from the island portion, a slope portion extending obliquely so as to connect the island portion and the bonding portion, and a lead portion extending from the bonding portion. First and second transistors and first and second diodes are mounted upper surfaces of island portions of respective first and second leads, and are connected to the respective leads through wirings that connect the transistors and diodes to the bonding portions of the respective leads. Lower surfaces of the island portions are attached to an upper surface of a circuit board, and the circuit board, the transistors, the diodes, and the lead frame are encapsulated by a resin, so that the lead portions are not covered by the resin.

In a semiconductor device, a thinly-molded portion covering a whole of a heat dissipating surface portion of a lead frame and a die pad space filled portion are integrally molded from a second mold resin, because of which adhesion between the thinly-molded portion and lead frame improves owing to the die pad space filled portion adhering to a side surface of the lead frame. Also, as the thinly-molded portion is partially thicker owing to the die pad space filled portion, strength of the thinly-molded portion increases, and a deficiency or cracking is unlikely to occur.

A piezoelectric cooling system and method for driving the cooling system are described. The piezoelectric cooling system includes a first piezoelectric cooling element and a second piezoelectric cooling element. The first piezoelectric cooling element is configured to direct a fluid toward a surface of a heat-generating structure. The second piezoelectric cooling element is configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.
