Abstract
Description
- This invention relates to the wedge-bonding of wires in the manufacture of electronic devices. In particular, it relates to wedge-bonding methods, machines and tools, and also to electronic devices that include connections in the form of wires which are wedge-bonded using such methods or machines or tools.
- The wedge-bonding of wires is a well-established technology that has been used for many decades to provide connections in electronic devices. By way of example, the following is a selection of recent United States patents on wedge bonding: U.S. Pat. No. 6,354,479, U.S. Pat. No. 6,135,341, U.S. Pat. No. 5,958,270, U.S. Pat. No. 5,950,903, U.S. Pat. No. 5,945,065, U.S. Pat. No. 5,906,706, U.S. Pat. No. 5,836,071, U.S. Pat. No. 5,702,049, U.S. Pat. No. 5,495,976, U.S. Pat. No. 5,452,838, U.S. Pat. No. 5,445,306, U.S. Pat. No. 5,364,004, U.S. Pat. No. 5,217,154, U.S. Pat. No. 5,148,959, U.S. Pat. No. 5,018,658, and U.S. Pat. No. 5,007,576. The whole contents of these US patents are hereby incorporated herein as reference material. The bonding tool (typically of tungsten carbide) generally comprises a shank having the wedge-bonding tip at one end.
- There is always a desire for cost reduction. One of the many items that involves an on-going cost is the need to periodically replace the bond tool when its bonding tip is becoming worn through use.
- It is an aim of the present invention to reduce the cost of replacing the bond tool.
- According to one aspect of the invention, there is provided a reversible bonding tool having a wedge-bonding tip at opposite ends of the tool. Thus, the present invention provides a dual-tip reversible tool, that increases the use time before replacement of the tool is required. Thus, a saving can be achieved in tool material.
- According to another aspect of the invention, there are provided wire-bonding machines having such a reversible bonding tool in accordance with the present invention.
- According to a further aspect of the invention, there are provided wedge-bonding methods, wherein:
-
- a reversible bonding tool in accordance with the present invention is used,
- and, after using the tip at one end for bonding wires, the tool is reversed to use the wedge-bonding tip at the opposite end for bonding further wires.
- According to yet another aspect of the invention, there are provided electronic devices, for example an integrated circuit or a power semiconductor device, that include connections in the form of wires which are wedge-bonded using such a method or machine or tool in accordance with the present invention.
- Various advantageous features and feature-combinations in accordance with the present invention are set out in the appended Claims. These and others are illustrated in embodiments of the invention that are now described, by way of example, with reference to the accompanying diagrammatic drawings, in which:
-
FIGS. 1A and 1B are a schematic side-view of part of an ultrasonic wedge-bonding machine in an embodiment of the present invention, during use at successive times in the manufacture of electronic devices; -
FIG. 2A is a downward-looking perspective view of the reversible bonding tool ofFIG. 1 , particularly of its working ends, and showing a bonding tip at its upper end in accordance with the invention; and -
FIG. 2B is a upward-looking perspective view of the lower working end of the bonding tool ofFIG. 2 , showing the bonding tip at this lower end. - It should be noted that all the Figures are diagrammatic. Relative dimensions and proportions of parts of these Figures have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings. The same reference signs are generally used to refer to corresponding or similar features in modified and different embodiments.
-
FIGS. 1A and 1B illustrate a wire-bonding stage in the manufacture ofelectronic devices tip bonding tool 10 is used having a bonding tip (also termed “wedge”) 1, 2 at each of theopposite ends FIG. 2A and 2B . - After extensive use of the wedge-bonding tip 1 at one
end 11 for bonding wires 21 (as illustrated inFIG. 1A ), the tip 1 is worn somewhat. Instead of needing to replace the bond tool as in the prior art, thetool 10 in accordance with the present invention is then reversed to use the wedge-bonding tip 2 at theopposite end 12 for bondingfurther wires 21′ (as illustrated inFIG. 1B ). Thus, a cost saving is achieved with regard to tool material. - Apart from using the
reversible tool 10 in accordance with the present invention, the wedge-bonding process and the wire-bonding machine may be of known forms and so will not be described in detail. - Thus,
FIGS. 1A and 1B illustrate the work area of the machine, where thedevice work mount 32.Wire wire bond pad device bond pad FIG. 1A ; 12 inFIG. 1B ) of thetool 10. Thewire bond pad gold wire wire bond pad - While being pressed against the
bond pad wire pad transducer 30 that applies ultrasonic energy to thewire pad respective bonding tip 1 or 2 of thetool 10.FIGS. 1A and 1B schematically show thetool 10 mounted in a horn of thetransducer 30. The horn can be of known form coupled to the source (not shown) of the ultrasonic energy. - In the embodiment illustrated in
FIGS. 1A and 1B , thebond tool 10 comprises a shank, with tapered work ends 11 and 12 at the opposite ends of the shank. Narrow bonding tips 1 and 2 (which engage with thewire FIGS. 2A and 2B . In the interests of simplicity of drawing, the taper is not shown inFIGS. 2A and 2B . - There are a variety of known geometries and structures that may be adopted for the work end and wedge tip.
FIGS. 1A , 1B, 2A and 2B illustrate a very simple grooved structure for thetips 1, 2 at the opposite working ends 11, 12, formed integral with the shank. In this case, the entire bonding tool 10 (its shank, its ends and its tips) may be of tungsten carbide. The single groove illustrated for eachtip 1 and 2 inFIGS. 2A and 2B serves for retaining the wire in position against the bond pad during the ultrasonic bonding. In more complex tip designs, cross-grooves and/or protrusions may also be included. -
FIGS. 1A and 1B do not show any detail of the wire-bonding machine in respect of the mounting of thetool 10 in thetransducer horn 30. This mount 31 couples thetool 10 ultrasonically to the transducer in known manner. However, the form of themount 31 and the tool shank are such as to allow thetool 10 to be reversed in themount 31, so as to permit wire bonding using either the wedge-bonding tip 1 at one end 11 (FIG. 1A ) or the wedge-bonding tip 2 at the opposite end 12 (FIG. 1B ). - This reversible mount aspect is most readily achievable when the
mount 31 engages the shank of thetool 10 at a position in between its opposite ends 11, 12. In the embodiment illustrated inFIGS. 1A and 1B , there is a different mount position on the tool shank when the respective ends 11 and 12 are used, but the shank is of the same (i.e. uniform) cross-section along at least the length(s) where these mount positions are present. - The drawings have shown only a very simple basic form for the tool and a schematic representation of the machine and of the bonding process. It will be apparent to persons skilled in the art that this basic form can be extended, embellished and modified with the type of features that are commonly used or sometimes used in the art.
- Thus, for example,
FIG. 1 does not show how thewire device bond pad bond tool 10 may be used close to the workingtip 1, 2 when thetool 10 has the very simple structure illustrated inFIGS. 1 and 2 . In other embodiments, a guide hole for the wire may be present in thebond tool 10. Thus, for example, separate guide holes (providing a through passage for thewire end tool 10, or there may be a single feed hole (in the form of a capillary bore) that extends through the length of thetool 10. - In the embodiment described above, the
whole bond tool 10 is composed of tungsten carbide. However, other embodiments may use other materials, for example, using hardened steel for the shank or titanium carbide for the shank. - Different known materials may be used for different parts of the tool 10 (the shank, the work ends 11 and 12, and the bonding tips 1 and 2), both bulk materials and coatings. The shank itself may be formed of a relatively hard, stiff material having a high modulus of elasticity (such as tungsten carbide, hardened steel, or titanium carbide), whereas other materials that are hard, precision-shaped and more abrasion resistant may be used at its opposite ends 11 and 12. Thus, for example, the
bonding tips 1 and 2 themselves may comprise a ceramic material or another, more expensive material such as diamond or osmium. - From reading the present disclosure, many other variations and modifications will be apparent to persons skilled in the art. Such variations and modifications may involve equivalent and other features which are already known in the design, manufacture and use of wedge-bonding tools and machines and of electronic devices having wedge-bonded wires, and which may be used instead of or in addition to features already described herein. Examples of such features are to be found in the US patents cited herein previously as reference material.
- Although Claims have been formulated in this Application to particular combinations of features, it should be understood that the scope of the disclosure of the present invention also includes any novel feature or any novel combination of features disclosed herein either explicitly or implicitly or any generalisation thereof, whether or not it relates to the same invention as presently claimed in any Claim and whether or not it mitigates any or all of the same technical problems as does the present invention.
- The Applicants hereby give notice that new Claims may be formulated to such features and/or combinations of such features during the prosecution of the present Application or of any further Application derived therefrom.
