Definitions
- Bonding structure wire bonding method, actuator device, and liquid jet head
- the present invention relates to a bonding structure of a bonding wire connected to a bonding pad and a wire bonding method, and is applied to an actuator device provided with a diaphragm and a piezoelectric element, in particular, a nozzle opening for discharging ink droplets.
- a part of the pressure generation chamber that communicates is configured by a diaphragm, and a piezoelectric element is formed on the surface of the diaphragm, and is suitable for application to a liquid ejecting head that ejects ink droplets by displacement of a piezoelectric layer. is there.
- An actuator device including a piezoelectric element that is displaced by applying a voltage is mounted on, for example, a liquid ejecting head that ejects liquid droplets.
- a liquid ejecting head for example, a part of a pressure generating chamber communicating with a nozzle opening is configured by a vibration plate, and the vibration plate is deformed by a piezoelectric element to pressurize ink in the pressure generating chamber.
- Inkjet recording heads that eject ink droplets from nozzle openings are known.
- a drive IC is mounted on a substrate to be bonded to a flow path forming substrate in which a pressure generating chamber is formed, for example, a reservoir forming substrate, and pulled out from each piezoelectric element.
- a structure is employed in which the terminal portion of the lead electrode and the driving IC are electrically connected by a bonding wire using wire bonding (see, for example, Patent Document 1).
- wire bonding is performed using a cable, after connecting one end of the connection wiring to the terminal portion of the driving IC and then connecting the other end of the bonding wire to the lead electrode. This is done by connecting to the bonding pad which is the terminal part.
- wire bonding is performed while heating at a temperature of 150 ° C or higher.
- a temperature of 150 ° C or higher By heating at such a high temperature, there is a problem in that each substrate constituting the ink jet recording head is thermally expanded and destroyed. For this reason, when wire bonding is performed on an inkjet recording head, it is necessary to perform heating at as low a temperature as possible.
- wire bonding performed at a low temperature bonding wire and bonding are performed. There is a problem that sufficient bonding strength with the pad cannot be secured.
- the wiring of devices using bonding wires typified by ink jet recording heads is required to have a high density.
- the bonding wire is pressed and connected to the bonding pad with a load of 294 to 882 X 10 _3 N, so the bonding part of the bonding wire connected to the bonding pad (
- the stitch portion is formed with a stitch width of 2 to 3 times the wire diameter and a stitch thickness of 0.1 times or less of the wire diameter.
- the bonding pad has to be formed wider than the width of the stitch portion, and there is a problem that the bonding pad cannot be densified by reducing the width and pitch of the bonding pad.
- Patent Document 2 Although the same bonding strength as that of the conventional bonding wire can be ensured, only the crimping dimension is forced, so that the bonding strength can be increased. There is a problem that you can not. Further, in Patent Document 2, there is a problem that a process of providing a concave portion or a convex portion in the bonding wire portion of the electrode is required, which complicates the manufacturing process and increases the manufacturing cost.
- the above-mentioned problems also exist in devices having a bonding wire connection structure using semiconductor elements such as LSIs and ICs that can be used only by liquid jet heads such as ink jet recording heads.
- the bonding wire When wire bonding is performed, the bonding wire is pressed against the bonding node by means of a capillary, and the bonding wire is brought into an unconstrained state to raise the power to a state where the bonding wire is fed out by a predetermined amount. With the bonding wire in a restrained state, the lift is further lifted, and the thinned portion is pressed to break. After this, the next step after the predetermined amount of the bonding wire has been fed out It moves to the joining part and performs joining work.
- Patent Document 3 and Patent Document 4 propose securing the strength of the joint portion by forming a bump with a ball or performing ball bonding.
- the actual situation is that the bonding strength cannot be improved at low temperatures.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2002-160366 (page 3, FIG. 2)
- Patent Document 2 JP-A-5-251856 (Pages 2 and 3, Fig. 1)
- Patent Document 3 JP 2000-252315 A
- Patent Document 4 JP-A-5-129357
- an object of the present invention is to provide a bonding structure and a wire bonding method capable of improving the bonding strength even in the case of wire bonding at low temperature heating.
- the present invention provides an actuator device and a liquid jet head that employ a bonding structure that can improve the bonding strength even in wire bonding at low temperature heating. Is an issue.
- a bonding site where a bonding wire is connected to a bonding pad includes a first connection site on the tip end side and the first connection site.
- the bonding structure is characterized by comprising a continuous second connection portion.
- the second bonding portion is continuous with the first connection portion and the first connection portion even in the case of wire bonding at a relatively low temperature compared to a general wire bonding temperature of 150 ° C. Since it is composed of connection parts, the bonding strength between the bonding wire and the bonding pad can be improved. By improving the bonding strength, the stitch width of the bonding wire connected to the bonding pad can be reduced, and the bonding pad width can be reduced and the pitch of the adjacent bonding pads can be reduced. .
- a second aspect of the present invention is the bonding structure according to the first aspect, wherein the second connection part has a higher tensile strength than the first connection part. .
- the second connecting portion has a high tensile strength V, so that bonding is possible. The bonding strength between the wire and the bonding pad can be improved.
- the second connection portion is connected to the first connection portion by applying an ultrasonic wave having a large amplitude. It has a characteristic bonding structure.
- the second connection portion is connected by applying a large amplitude ultrasonic wave. As a result, the bonding strength between the bonding wire and the bonding pad can be improved.
