An LED includes an LED chip, a substrate, a first electrode and a second electrode formed on the LED chip, and a first solder layer and a second solder layer formed on a top face of the substrate. The first solder layer is soldered on the first electrode and sandwiched between the LED chip and the substrate. The second solder layer is soldered on the second electrode and sandwiched between the LED chip and the substrate. A projection of the first solder layer on the top face of the substrate exceeds a periphery of a projection of the LED chip on the top face of the substrate. A projection of the second solder layer on the top face of the substrate exceeds the periphery of the projection of the LED chip on the top face of the substrate.

A method of packaging a power semiconductor die includes providing a first lead frame of a dual gauge lead frame. The first lead frame includes a thick die pad. A tape is attached to a first side of the thick die pad and the power die is attached to a second side of the thick die pad. A second lead frame of the dual gauge lead frame is provided. The second lead frame has thin lead fingers. One end of the lead fingers is attached to an active surface of the power die such that the lead fingers are electrically connected to bonding pads of the power die. A molding compound is then dispensed onto a top surface of the dual gauge lead frame such that the molding compound covers the power die and the lead fingers.

Consistent with an example embodiment, there is a semiconductor device, having a topside surface and an underside surface, the semiconductor device comprises an active device of an area defined on the topside surface, the topside surface having a first area. A protective material is on to the underside surface of the semiconductor device, the protective material has an area greater than the first area. A laminating film attaches the protective material to the underside surface. The protective material serves to protect the semiconductor device from mechanical damage during handling and assembly onto a product's printed circuit board.

A method of making an assembly includes the steps of applying metallic nanoparticles to exposed surfaces of conductive elements of either of or both of a first component and a second component, juxtaposing the conductive elements of the first component with the conductive elements of the second component with the metallic nanoparticles disposed therebetween, and elevating a temperature at least at interfaces of the juxtaposed conductive elements to a joining temperature at which the metallic nanoparticles cause metallurgical joints to form between the juxtaposed conductive elements. The conductive elements of either of or both of the first component and the second component can include substantially rigid posts having top surfaces projecting a height above the surface of the respective component and edge surfaces extending at substantial angles away from the top surfaces thereof.

摘要:
A method for aligning a first substrate relative to a second substrate by enabling reflow of low-melting-temperature solder bumps is disclosed. Reflow of the solder bumps induces a force that moves one substrate relative to the other to improve alignment accuracy between bond pads located on each substrate. The method further enables reduction of surface oxide on the solder bumps that would otherwise inhibit reliable solder joint formation.

A package of an electronic device, a system including the same and a method for fabricating the same are provided. The package of the electronic device includes a substrate, a step difference layer and a connecting bump. The substrate allows a connecting contact part to be exposed on a surface thereof. The step difference layer covers the substrate so as to leave the connecting contact part exposed. The connecting bump is connected to the connecting contact part so that one end part of the connecting bump is extended on the step difference layer, and has a sloped upper surface formed by a step difference formed by the step difference layer.
