A semiconductor device includes: a thick copper member in which a semiconductor chip is mounted; a printed circuit board that is disposed on a front surface of the thick copper member and provided with an opening exposing a part of the front surface of the thick copper member, a wiring pattern, and conductive vias connecting the pattern and the thick copper member; a semiconductor chip mounted on the front surface of the thick copper member exposed through the opening and connected to the pattern by a metal wire; an electronic component mounted on a front surface of the printed circuit board opposite to a side facing the thick copper member and connected to the pattern; and a cap or an epoxy resin sealing the front surface of the printed circuit board opposite to a side facing the thick copper member, the chip, the component, and the metal wire.

A semiconductor device including a substrate; a chip on which a surface electrode is formed; and a lead. The lead includes a first electrode connecting portion disposed on the surface electrode and electrically connected to the surface electrode of the chip via a conductive bonding material; a second electrode connecting portion electrically connected to an electrode portion of a wiring pattern. A lead connected to the first electrode connecting portion and the second electrode connecting portion. The lead further has a thermal shrinking stress equalizing structure on a portion of an outer periphery of the first electrode connecting portion. The lead is configured to make a thermal shrinking stress applied to a conductive bonding material between the first electrode connecting portion and the surface electrode equal.

A method for manufacturing a semiconductor device includes preparing a first substrate provided with a first pattern on a first surface, and a semiconductor chip having a second surface, and a third surface opposite to the second surface, and including a second pattern provided on the second surface, recognizing the first pattern from a position near the first surface among the first surface and an opposite surface thereof in the first substrate, recognizing the second pattern by transmitting through the semiconductor chip from a position near the third surface among the second surface and the third surface in the semiconductor chip, aligning the semiconductor chip and the first substrate based on a recognition result of the first pattern and the second pattern, and bonding the semiconductor chip to the first substrate so that the second surface faces the first surface.

A foil-based package and a method for manufacturing a foil-based package includes, among other things, a first and a second foil substrate. An electronic component is arranged between the two foil substrates in a sandwich-like manner. Due to the component thickness, there is a distance difference between the two foil substrates between the mounting area of the component and ears outside of the mounting area. The foil-based package and the method provides means for reducing and/or compensating a distance difference between the first foil substrate and the second foil substrate caused by the component thickness.

Ceramic interposers in a disaggregated-die semiconductor package allow for useful signal integrity and interconnecting components. Low-loss ceramics are used to tune ceramic interposers for a die assembly that may have components from different process-technology nodes.

A circuit assembly may include a substrate and a pattern of contact points formed from deformable conductive material supported by the substrate. The assembly may further include an electric component supported by the substrate and having terminals arranged in a pattern corresponding to the pattern of contacts points. The one or more of the terminals of the electric component may contact one or more of the corresponding contact points to form one or more electrical connections between the electric component and the contact points.

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.

A semiconductor device has a first build-up interconnect structure formed over a substrate. The first build-up interconnect structure includes an insulating layer and conductive layer formed over the insulating layer. A vertical interconnect structure and semiconductor die are disposed over the first build-up interconnect structure. The semiconductor die, first build-up interconnect structure, and substrate are disposed over a carrier. An encapsulant is deposited over the semiconductor die, first build-up interconnect structure, and substrate. A second build-up interconnect structure is formed over the encapsulant. The second build-up interconnect structure electrically connects to the first build-up interconnect structure through the vertical interconnect structure. The substrate provides structural support and prevents warpage during formation of the first and second build-up interconnect structures. The substrate is removed after forming the second build-up interconnect structure. A portion of the insulating layer is removed exposing the conductive layer for electrical interconnect with subsequently stacked semiconductor devices.

A method of manufacturing a light emitting device includes: providing a substantially flat plate-shaped base member which in plan view includes at least one first portion having an upper surface, and a second portion surrounding the at least one first portion and having inner lateral surfaces; mounting at least one light emitting element on the at least one first portion; shifting a relative positional relationship between the at least one first portion and the second portion in an upper-lower direction to form at least one recess defined by an upper surface of the at least one first portion that serves as a bottom surface of the at least one recess and at least portions of the inner lateral surfaces of the second portion that serve as lateral surfaces of the at least one recess; and bonding the at least one first portion and the second portion with each other.

A fabric-based item may include fabric layers and other layers of material. An array of electrical components may be mounted in the fabric-based item. The electrical components may be mounted to a support structure such as a flexible printed circuit. The flexible printed circuit may have a mesh shape formed from an array of openings. Serpentine flexible printed circuit segments may extend between the openings. The electrical components may be light-emitting diodes or other electrical devices. Polymer with light-scattering particles or other materials may cover the electrical components. The flexible printed circuit may be laminated between fabric layers or other layers of material in the fabric-based item.
