Mechanical strength is approx. 80% higher than the existing product, maintaining strength at high temperatures, supporting high heat resistance demand for power devices
|Appearance of TALF|
In addition to mechanical strength being approximately 80% higher than the existing product, TALF can contribute to an increase in the heat resistance temperature of packages because of its recrystallization temperature 50 degrees Celsius higher than the existing product. Furthermore, although the existing product hardened and recrystallized in 30 minutes in the high-temperature shelf test (300 degrees Celsius) after bonding, resulting in shear strength decreasing by approximately 10%, TALF is not subject to a decrease in shear strength because recrystallization does not commence. Because of this, shear strength can maintain even at high temperatures.
Normally, bonding wire can prevent damage from thermal fatigue when mechanical strength is raised by hardening the material, but this simultaneously damages IC chip easily during bonding. TALF is an alloy containing 99% aluminum, and by optimizing the processing method using finer particles of aluminum crystals, the company succeeded in providing high strength and high heat resistance without damaging the chip.
Aluminum bonding wire is currently used as material for large-current semiconductors such as power devices. In recent years, there have been demands for development of high heat resistant materials as power devices have higher density, become more compact and have higher output, TALF can contribute to improve heat resistance temperature of packages. The features of TALF are as follows.
- High mechanical strength
TALF has improved mechanical strength by approximately 80% by optimizing the processing method using finer particles of aluminum crystals. The hardness of the cross-section of the wire contact after bonding is almost the same as the existing product, and does not damage the chip during bonding. This is due to an optimized material composition.
* Comparison of Vickers hardness (Hv) ---------------------------------------------------------------------- TALF Existing product ---------------------------------------------------------------------- Wire cross-section Hv 25.1 20.0 Contact cross-section Hv 35.0 34.8 ----------------------------------------------------------------------- High thermal fatigue strength
In addition to mechanical strength being approximately 80% higher than the existing product, whereas the existing product has reduced shear strength due to early recrystallization in high-temperature shelf tests, TALF does not have reduced shear strength because it does not recrystallize due to the recrystallization temperature by 50 degrees Celsius and higher. This contributes to higher thermal resistance of power devices as the wire is able to suppress thermal fatigue damage in power cycle tests(*1) and thermal cycle tests(*2).
- Provides other excellent performances
The bonding properties are the same as the existing product, enabling bonding under identical conditions. In addition, the corrosion resistance is the same as the existing product, and the wire has been confirmed no corrosion even after 1,000 hours in a pressure cooker test (PCT). Furthermore, despite having 99% purity, the specific resistance is almost the same as the existing product at 2.8 micro-ohm centimeters.
Tanaka Denshi Kogyo has a leading share in the global market for aluminum bonding wire, and has provided the existing product, TANW since 1988. TALF is the first new aluminum bonding wire product in 26 years. Tanaka Denshi Kogyo aims for TALF sales of 100 million yen per month in 3 years through the replacement of the existing product and the development of new demands.
Tanaka Denshi Kogyo has scheduled to exhibit TALF at the 15th IC Packaging Technology Expo to be held at Tokyo Big Sight (Koto-ku, Tokyo) for three days from January 15 (Wed) until January 17 (Fri). Technical staff will constantly be on-site in the exhibit booth (East 43-001) to respond to interviews.
