A semiconductor device and a method of manufacturing a semiconductor device. As a non-limiting example, various aspects of this disclosure provide a semiconductor device comprising multiple encapsulating layers and multiple signal distribution structures, and a method of manufacturing thereof.

A semiconductor device includes a substrate that includes an opening extending through a thickness of the substrate, a frame that includes an integrated circuit (IC) die pad in the opening and a plurality of arms extending outwardly from the IC die pad, an IC mounted on the IC die pad, a plurality of bonding elements electrically coupling the substrate with the IC without the frame being an intermediary coupling element, and an encapsulant surrounding the IC, the plurality of bonding elements, and the plurality of arms. The substrate has a first major surface and a second major surface. Each arm is devoid of a contact pad. Each arm has a distal end coupled to the first major surface of the substrate, and each arm has a proximal end disposed over the first major surface of the substrate.

A process for bonding chips to a substrate by direct bonding includes providing a support with which the chips are in contact, the chips in contact with the support being separate from one another. This bonding process also includes forming a liquid film on one face of the substrate, bringing the chips into contact with the liquid film, where the action of bringing the chips into contact with the liquid film causes attraction of the chips toward the substrate, and evaporating the liquid film in order to bond the chips to the substrate by direct bonding.

A semiconductor device is provided that includes a lead frame, a die attached to the lead frame using a first solder, a source clip and a gate clip attached to the die using a second solder, and a drain clip attached to the lead frame. The semiconductor device is inverted, so that the source clip and the gate clip are positioned on the bottom side of the semiconductor device, and the lead frame is positioned on the top side of the semiconductor device so that the lead frame is a top exposed drain clip.

A semiconductor device includes a multi-layer board which a wiring pattern and a grounding pattern are formed. A plurality of semiconductor elements are mounted on the multi-layer board. An insulating sealing member is provided on the multi-layer board and is covering the plurality of semiconductor elements. A metal film is provided on the insulating sealing member. An in-groove metal is provided in contact with a plurality of grooves extending from a side-surface upper end of the insulating sealing member to a side-surface lower end of the multi-layer board. An in-hole metal is provided in an inner wall of a hole penetrating through the insulating sealing member and is extending to the multi-layer board. The in-hole metal is contacting with the metal film and the grounding pattern.

A power module includes a metal frame having a first and second device attach pads, first and second semiconductor packages each having an encapsulant body, a die pad exposed at a lower surface of the encapsulant body, a plurality of leads protruding out from the encapsulant body, and a potting compound that encapsulates both of the first and second semiconductor packages and partially covers the metal frame. The first semiconductor package is mounted on the metal frame such that the die pad of the first semiconductor package faces and electrically contacts the first device attach pad. The second semiconductor package is mounted on the metal frame such that the die pad of the second semiconductor package faces and electrically contacts the second device attach pad. The plurality of leads from each of the first and second semiconductor packages are electrically accessible from outside of the potting compound.

A die dipping structure includes a plate including a first recessed portion having a first depth and filled with a first flux material. The plate further includes a second recessed portion, isolated from the first recessed portion, with a second depth and filled with a second flux material. The second depth is different from the first depth. The die dipping structure further includes a motor configured to move the plate so as to simultaneously dip a first die and a second die into the flux of the first recessed portion and the flux of the second recessed portion, respectively.

A method includes forming an interconnect component including a plurality of dielectric layers that include an organic dielectric material, and a plurality of redistribution lines extending into the plurality of dielectric layers. The method further includes bonding a first package component and a second package component to the interconnect component, encapsulating the first package component and the second package component in an encapsulant, and precutting the interconnect component using a blade to form a trench. The trench penetrates through the interconnect component, and partially extends into the encapsulant. The method further includes performing a singulation process to separate the first package component and the second package component into a first package and a second package, respectively.

The present disclosure provides a package device and a manufacturing method thereof. The package device includes an electronic device, a conductive pad having a first bottom surface, and a redistribution layer disposed between the conductive pad and the electronic device. The redistribution layer has a second bottom surface, and the conductive pad is electrically connected to the electronic device through the redistribution layer. The first bottom surface is closer to the electronic device than the second bottom in a normal direction of the electronic device.

A semiconductor structure includes a fan-out package, a packaging substrate, an solder material portions bonded to the fan-out package and the packaging substrate, an underfill material portion laterally surrounding the solder material portions, and at least one cushioning film located on the packaging substrate and contacting the underfill material portion and having a Young's modulus is lower than a Young's modulus of the underfill material portion.
