Sputtering Targets for Photovoltaic Applications
- Ultrasonic defect testers ensure meticulous quality assurance!
ULVAC has installed large ultrasonic test equipment to make meticulous defect inspections of materials and bonding inspections. Using this equipment has helped ULVAC drastically cut down on arcing during sputtering and deliver high quality targets.
- High-reliability metal bonding technology
Large sputtering targets are very heavy so technology for bonding to a cooling plate (backing plate) is extremely important. ULVAC has installed bonding equipment to support deposition of larger glass substrate, and realized an all-inclusive target supply system.
- Low-particle targets
- Attaining high uniformity by adjusting the metal microstructure
