A terminal (10) includes a first surface (10a), a second surface (10b), and an end surface having first and second recessed areas (10ca, 10cb) that are extend from the first and second surfaces, respectively. The resin portion (20) is integrally formed with the terminal, and at least partially covers the end surface so that the first and second surfaces are at least partially exposed. The resin portion forms a recessed part to accommodate the light emitting device. The second recessed area includes a closest point (P) that is positioned closest to the first surface and an extension part (10cbe) that extends outward of the closest point and toward the second surface (10b) side. The extension part is formed at least on opposing end surfaces of the pair of positive and negative lead terminal. The first recessed area is arranged on the exterior side relative to the closest point.

Consistent with an example embodiment, there is an integrated circuit (IC) device in a packaging having electrically insulated connections. The IC device comprises a semiconductor device (100) mounted onto a die attachment area (10); the semiconductor device has a plurality of bonding pads (20a, 25a, 30a, 35a). A lead frame having a plurality of bonding fingers (20b, 25b, 30b, 35b) surrounds the die attachment area. A plurality of mutually isolated connection conductors (25d, 30d, 40, 50) having respective first ends are attached to respective bonding pads on the semiconductor device and the plurality of mutually isolated connection conductors having respective second respective second ends are attached to respective bonding fingers of the lead frame. An insulating material (45) coats at least a portion of the plurality of mutually isolated connection conductors. The mutually isolated connection conductors may include a bond wire (40, 50) for the signal connection and a conductive strap (25d, 30d) for the voltage reference connection. The insulating material (45) coating the bond wires reduces the likelihood of short circuits during encapsulation.

An integrated circuit assembly (30) is disclosed herein. The assembly (30) includes a dielectric substrate (32) defining a predetermined array of electrically conductive traces (40) and an array of solder balls (42) electrically connected to the traces (40). An integrated circuit chip (44) having a series of input/output pads is supported on the substrate (32). In one embodiment, a plurality of leadframe leads (48) are supported by the substrate (32) in electrical isolation from and over the conductive traces (40). First and second series of bonding wires (56, 58) electrically connect certain ones of the input/output pads on the IC chip to the leadframe leads (48) and conductive traces (40). In other embodiments, one or more electrically isolated conductive layers are supported by the dielectric substrate (32) over the traces (40) and leadframe leads (48). The integrated circuit assembly (30), in accordance with any of these embodiments, provides a very high density electrical interconnection arrangement for the IC chip while retaining a small package footprint.
