11373974 · 2022-06-28 · ·

Electronic device package technology is disclosed. In one example, an electronic device includes a substrate having a bond finger, a die coupled to the substrate and having a bond pad, a first bond wire coupled between the bond pad and the bond finger, and a second bond wire coupled between the bond pad and the bond finger. The first bond wire is reverse bonded between a pad solder ball on the bond pad and a finger solder ball on the bond finger. The second bond wire is forward bonded between a supplemental pad solder ball on the pad solder and the bond finger adjacent the finger solder ball. Associated systems and methods are also disclosed.

Semiconductor device with die-skipping wire bonds

A semiconductor device is disclosed including a wire bonded die stack where the bond wires skip dies in the die stack to provide bond wires having a long length. In one example, the semiconductor dies are stacked on top of each other with offsets along two orthogonal axes so that the dies include odd numbered dies interspersed and staggered with respect to even numbered dies only one of the axes. Wire bonds may be formed between the odd numbered dies, skipping the even numbered dies, and wire bonds may be formed between the even numbered dies, skipping the odd numbered dies. The long length of the bond wires increases an inductance of the wire bonds relative to parasitic capacitance of the semiconductor dies, thereby increasing signal path bandwidth of the semiconductor device.

CIRCUIT STRUCTURE

A circuit structure including a pad assembly, a bonding pad assembly, and a bonding assembly is provided. The pad assembly includes a first pad, a second pad, and a third pad which are separated from one another. The bonding pad assembly is located on one side of the pad assembly and includes a first bonding pad. The bonding assembly includes a first bonding wire, a second bonding wire, and a plurality of bonding members. The first bonding wire is connected to the first bonding pad and the first pad. The second bonding wire is connected to the first bonding pad and the third pad. The bonding members are connected among the first pad, the second pad, and the third pad. The circuit structure provided here may have an improved wire bonding efficiency and an increased distribution density of bonding points, and the number of bonding wires may be reduced.

SEMICONDUCTOR DEVICE INCLUDING VERTICAL WIRE BONDS

A semiconductor device includes a vertical column of wire bonds on substrate contact fingers of the device. Semiconductor dies are mounted on a substrate, and electrically coupled to the substrate such that groups of semiconductor dies may have bond wires extending to the same contact finger on the substrate. By bonding those wires to the contact finger in a vertical column, as opposed to separate, side-by-side wire bonds on the contact finger, an area of the contact finger may be reduced.
