The copper bonding wire is characterized in that when a sum of percentages of Cu, Cu.sub.2O, CuO and Cu(OH).sub.2 on a surface of the wire as measured by X-ray Photoelectron Spectroscopy (XPS) is defined as 100%, Cu[II]/Cu[I] which is a ratio of a total percentage of CuO and Cu(OH).sub.2 (Cu[II]) corresponding to bivalent Cu to a percentage of Cu.sub.2O (Cu[I]) corresponding to monovalent Cu falls within a range from 0.8 to 12.

Interconnect structures for power semiconductor device packages are provided. In one example, a power semiconductor device package may include one or more semiconductor die, a submount, and at least one interconnect structure. The one or more wide bandgap semiconductor die may be on the submount. The at least one interconnect structure may include at least one texturized surface.

An example semiconductor package a bridge die disposed in a recess of an underlying substrate, the bridge die including a via that electrically couples a first contact on a first side of the bridge die and a second contact on a second side of the bridge die, the recess extending to a first surface of the underlying substrate; a bond material to electrically and mechanically couple the first contact and an interconnect of the underlying substrate; and a fill material positioned between the first side of the bridge die and the first surface of the underlying substrate.

A connecting strip of conductive elastic material having an arched shape having a concave side and a convex side.

During bonding, the connecting strip undergoes elastic deformation and presses against the die, thus electrically connecting the at least one die to the support.

A manufacturing method of a semiconductor device includes: a first step of, after joining a wire to an electrode using a capillary, forming a wire part by moving the capillary to a third target point while feeding out the wire; a second step of forming a bent part by moving the capillary to a fourth target point while feeding out the wire; a third step of processing the bent part into a planned cut part by repeating lowering and raising of the capillary for multiple times; and a fourth step of cutting the wire at the planned cut part by raising the capillary with a wire clamper closed to form a pin wire.

A semiconductor device has a first substrate. A first semiconductor die and second semiconductor die are disposed over the substrate. An interconnect bridge is disposed over the first semiconductor die and second semiconductor die. The interconnect bridge has a second substrate. A conductive trace is formed over a first surface of the second substrate. The conductive trace is electrically coupled from the first semiconductor die to the second semiconductor die. A conductive via is formed through the second substrate. An IPD is formed over a second surface of the second substrate. The IPD is electrically coupled to the first semiconductor die or second semiconductor die through the conductive via. An encapsulant is deposited over the first substrate, first semiconductor die, second semiconductor die, and interconnect bridge.

Bonding wire for semiconductor devices contains one or more of Be, B, P, Ca, Y, La, and Ce in a total of 0.031 at % to obtain a 0.180 at %, further contains one or more of In, Ga, and Cd in a total of 0.05 at % to 5.00 at %, and has a balance of Ag and unavoidable impurities. Due to this, it is possible to obtain a bonding wire for semiconductor devices sufficiently forming an intermetallic compound layer at a ball bond interface to secure the bond strength of the ball bond, not causing neck damage even in a low loop, having a good leaning characteristic, and having a good FAB shape.

An electronic assembly component may comprise at least one fan-out device comprising a first encapsulant disposed around a memory device or function and a processor device or function, and a fan-out interconnect structure disposed over the first encapsulant and the at least one fan-out device. Input output pads may be disposed over the fan-out interconnect structure. A structural support may comprise electrical routing and structural support pads, the structural support further comprising at least one mounting site to which the at least one fan-out device is coupled. An electrical connector may be configured to electrically couple the input output pads of the at least one fan-out device to the structural support pads. A second encapsulant may be disposed over at least a portion of the at least one fan-out device and the structural support.

An electronic device and method are provided. The method includes providing an array of electronic devices having leadframes where the leadframes include at least one depopulated lead and external leads interconnected by a first dambar, a second dambar, and a connection assembly. The connection assembly connects the first dambar to a first external lead of a first leadframe and to a second external lead of a second adjacent leadframe. A first punch process is performed to remove the first dambar and the second dambar from the leadframes. A second punch process is performed to create a cut in the connection assembly proximate the first external lead adjacent to the at least one depopulated lead to disconnect the connection assembly from the first external lead. A trimming process is performed to trim external leads of the leadframes to their required length while simultaneously removing the connection assembly.
