Embodiment Construction

[0027] While the invention is subject to various modifications and alternative forms, specific examples thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the invention should not be limited to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope and spirit of the invention as defined by the appended claims.

[0028] The present invention has been found to be helpful in reducing the likelihood of electrical lead shorting in wire bond packages. Avoid short circuits by insulated bonding wires with resilient insulating material. In addition, the electrical performance of the wire bonded package is improved by using conductive straps to connect power and ground between their respective bond pads and the lead fingers of the package lead frame. The conductive tape reduces the impedance of the insulated ...

Abstract

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.

Description

technical field [0001] The present invention relates to integrated circuit (IC) packaging. More particularly, the present invention relates to wire bonding IC device dies wherein selected connecting wires between the semiconductor die and a packaging substrate are covered with an insulating material. Background technique [0002] The electronics industry continues to rely on advances in semiconductor technology to achieve higher performance devices in tighter areas. For many applications, achieving higher performance devices requires integrating a large number of electronic devices onto a single silicon wafer. As the number of electronic devices per given area of ​​a silicon wafer increases, the manufacturing process becomes more difficult. [0003] A variety of semiconductor devices have been fabricated for different applications with numerous rules. Such silicon-based semiconductor devices often include metal oxide semiconductor field effect transistors (MOSFETs), such ...
