The present invention discloses an implementation method for stacked connection between isolated circuit components, whose setting is according to at least two circuit components connecting in parallel/series in a circuit, wherein, in accordance with a circuit connection configuration, a plurality of corresponding pins of the components are soldered directly, making the components form an integrated module in accordance with a desired connection configuration of the circuit, and saving circuit boards and wires. Comparing to the circuit limited in a PCB in the prior art, it is possible to construct a circuit unit by welding connection in a way of building-block approach, achieving a circuit in a 3D space through directly welding between components, and owning a wider design space, it may shorten the time used for a circuit from design to process.

A chip package includes a first chip and a second chip. The first chip includes a first substrate having a first surface and a second surface opposite to the first surface, a first passive element on the first surface, and a first protection layer covering the first passive element, which the first protection layer has a third surface opposite to the first surface. First and second conductive pad structures are disposed in the first protection layer and electrically connected to the first passive element. The second chip is disposed on the third surface, which the second chip includes an active element and a second passive element electrically connected to the active element. The active element is electrically connected to the first conductive pad structure.

In a method for connecting components during production of power electronics modules or assemblies, surfaces of the components have a metallic surface layer upon supply, or are furnished therewith, wherein the layer has a surface that is smooth enough to allow direct bonding or is smoothed to obtain a surface that is smooth enough to allow direct bonding. The surface layers of the surfaces that are to be connected are then pressed against each other with a pressure of at least 5 MPa at elevated temperature, so that they are joined to each other, forming a single layer. The method enables simple, rapid connection of even relatively large contact surfaces, which satisfies the high requirements of power electronics modules.

A side-exposed embedded trace substrate includes a dielectric layer, a first wiring layer and a first wiring layer embedded in the dielectric layer. An outer surface of the first wiring layer is not higher than a surface of the dielectric layer, and the first wiring layer includes a pad having a groove to increase a side-exposed area of the pad. The contact area between the substrate and the solder during package welding is increased so that the welding reliability is enhanced, the problem of poor welding or poor reliability caused by trace embedding may be avoided, and poor filling of the packaging material due to insufficient gap between the device and the pad during packaging may be prevented.

A method forming packaged semiconductor devices includes providing a completed semiconductor package having a die with bond pads coupled to package pins. Sensor precursors including an ink and a liquid carrier are additively printed directly on the die or package to provide precursors for electrodes and a sensing material between the sensor electrodes. Sintering or curing removes the liquid carrier such that an ink residue remains to provide the sensor electrodes and sensing material. The sensor electrodes electrically coupled to the pins or bond pads or the die includes a wireless coupling structure coupled to the bond pads and the method includes additively printing an ink then sintering or curing to form a complementary wireless coupling structure on the completed semiconductor package coupled to the sensor electrodes so that sensing signals sensed by the sensor are wirelessly transmitted to the bond pads after being received by the wireless coupling structure.
