Abstract:
An electronic isolation device is formed on a monolithic substrate and includes a plurality of passive isolation components. The isolation components are formed in three metal levels. The first metal level is separated from the monolithic substrate by an inorganic PMD layer. The second metal level is separated from the first metal level by a layer of silicon dioxide. The third metal level is separated from the second metal level by at least 20 microns of polyimide or PBO. The isolation components include bondpads on the third metal level for connections to other devices. A dielectric layer is formed over the third metal level, exposing the bondpads. The isolation device contains no transistors.
Abstract:
A multilayer substrate that retains a curved state without causing fluctuations in electrical characteristics includes a main body including a plurality of insulating sheets to be stacked and made of a flexible material. A signal wire extends in the main body. A ground conductor is provided at a positive-direction side in a z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. A ground conductor is provided on a negative-direction side in the z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. The state in which the main body is curved so that the signal wire defines an arc is retained by plastic deformation of the ground conductors.

Abstract:
Methods and apparatus for an interposer with dams used in packaging dies are disclosed. An interposer may comprise a metal layer above a substrate. A plurality of dams may be formed above the metal layer around each corner of the metal layer. Dams may be formed on both sides of the interposer substrate. A dam surrounds an area where connectors such as solder balls may be located to connect to other packages. A non-conductive dam may be formed above the dam. An underfill may be formed under the package connected to the connector, above the metal layer, and contained within the area surrounded by the dams at the corner, so that the connectors are well protected by the underfill. Such dams may be further formed on a printed circuit board as well.

Abstract:
A light-emitting element mounting package includes a light-emitting element mounting portion that includes a plurality of wiring portions arranged interposing a predetermined gap between the wiring portions facing each other, and an insulating layer on which the light-emitting element mounting portion is mounted, wherein an upper surface of the light-emitting element mounting portion is exposed on the insulating layer, wherein cutout portions are formed on lower sides of side edges of the wiring portions and contact the insulating layer.
Abstract:
A connector for connection to terminals of an integrated circuit. The connector consists of a dielectric substrate having a first side and a second side. The connector has wire bond terminals which are attached to the first side of the substrate and configured to receive wire bonds connected to a first set of the terminals of the integrated circuit. The connector also has solder bump terminals, attached to the second side of the substrate so as to be insulated from the wire bond terminals, the solder bump terminals being configured to be coupled via solder balls with a second set of the terminals of the integrated circuit.
Abstract:
An electronic structure (for example a reliability board or a cycling control module) has a body including a body portion insertable into a connector. A plurality of contact structures are provided on a side of the body portion, each contact structure comprising a first contact and a second contact spaced from the first contact, with the first and second contacts of each contact structure being aligned in the direction of insertion of the body portion into the connector. A corresponding second plurality of contact structures is provided on a side of the body portion opposite the first—mentioned side. These contacts connect with respective corresponding contacts of the connector.

Abstract:
A multi-chip package comprises a plurality of chip pads and a plurality of LED chips. The chip pads are arranged in an M×N array, M and N each a positive integer greater than 1. A peripheral area of each chip pad comprises a respective first bonding pad, a respective second bonding pad, and a respective third bonding pad arranged in sequence in a clockwise direction. A first orientation of the respective first to third bonding pads in a first row of the N rows differs from a second orientation of the respective first to third bonding pads in a second row of the N rows by 90 degrees. Each of the LED chips is disposed on a respective one of the chip pads and electrically connected to two of the respective first to third bonding pads on a same side of the respective LED chip.
