SEMICONDUCTOR PACKAGES USING PACKAGE IN PACKAGE SYSTEMS AND RELATED METHODS
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.
Semiconductor package with a cavity in a die pad for reducing voids in the solder
A semiconductor package having an aperture in a die pad and solder in the aperture coplanar with a surface of the package is disclosed. The package includes a die pad, a plurality of leads, and a semiconductor die coupled to the die pad with a die attach material. A cavity or aperture is formed through the die pad to expose a portion of the die attach material. Multiple solder reflows are performed to reduce the presence of voids in the die attach material. In a first solder reflow, the voids of trapped gas that form when attaching the die to the die pad are released. Then, in a second solder reflow, solder is added to the aperture coplanar with a surface of the die pad. The additional solder can be the same material as the die attach material or a different material.
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD OF THE SAME
A semiconductor device includes a support, a semiconductor chip, a first insulating film, and a wiring layer. The support comprises a first electrode. The semiconductor chip has a first surface facing the support and a second surface facing away from the support with a second electrode thereon. The first insulating film has a first portion in contact with the first surface and a second portion in contact with at least one side surface of the semiconductor chip. The wiring layer connects the first electrode to the second electrode. The wiring layer is on the support, the second surface of the semiconductor chip, a side surface of the second portion of the first insulating film.
SEMICONDUCTOR DEVICE AND CORRESPONDING METHOD OF MANUFACTURE
Disclosed herein is a method, including attaching a semiconductor chip to a chip mounting portion on at least one leadframe portion, and attaching a passive component on a passive component mounting portion of the at least one leadframe portion. The method further includes forming a laser direct structuring (LDS) activatable molding material over the semiconductor chip, passive component, and the at least one leadframe portion. Desired patterns of structured areas are formed within the LDS activatable molding material by activating the LDS activatable molding material. The desired patterns of structured areas are metallized to form conductive areas within the LDS activatable molding material to thereby form electrical connection between the semiconductor chip and the passive component. A passivation layer is formed on the LDS activatable molding material.
Method for electrically contacting a component by galvanic connection of an open-pored contact piece, and corresponding component module
The invention relates to a method for electrically contacting a component (10) (for example a power component and/or a (semiconductor) component having at least one transistor, preferably an IGBT (insulated-gate bipolar transistor)) having at least one contact (40, 50), at least one open-pored contact piece (60, 70) is galvanically (electrochemically or free of external current) connected to at least one contact (40, 50). In this way, a component module is achieved. The contact (40, 50) is preferably a flat part or has a contact surface, the largest planar extent thereof being greater than an extension of the contact (40, 50) perpendicular to said contact surface. The temperature of the galvanic connection is at most 100° C., preferably at most 60° C., advantageously at most 20° C. and ideally at most 5° C. and/or deviates from the operating temperature of the component by at most 50° C., preferably by at most 20° C., in particular by at most 10° C. and ideally by at most 5° C., preferably by at most 2° C. The component (10) can be contacted by means of the contact piece (60, 70) with a further component, a current conductor and/or a substrate (90). Preferably, a component (10) having two contacts (40, 50) on opposite sides of the component (10) is used, wherein at least one open-pored contact piece (60, 70) is galvanically connected to each contact (40, 50).
