Target Application Fields
1. Microelectronics: Targets are used for IC metallization, where the trend toward low-resistivity copper wiring drives the development of copper targets and the required barrier-layer target materials.
2. Target materials for flat panel displays: Flat panel displays (FPDs) have significantly replaced the computer monitor and television markets originally dominated by cathode ray tubes (CRT), increasing the technical and market demand for ITO targets.
3. Target materials for information storage: Targets are used for the deposition of recording layers and electrode layers in storage devices.
Development Trend
The technological development trend of target materials is closely related to the development trend of thin film technology in downstream application industries. As the application industry improves its technology in thin film products or components, target technology should also change accordingly. For example, IC manufacturers have recently been committed to the development of low-resistivity copper wiring; it is expected that the original aluminum film will be largely replaced in the next few years, so the development of copper targets and required barrier-layer target materials will be urgent.
General Uses
Sputtering targets are mainly used in the electronics and information industries, such as integrated circuits, information storage, LCD screens, laser memories, and electronic control devices; they can also be used in the field of glass coating; and they can also be used in wear-resistant materials, high-temperature corrosion resistance, high-end decorative supplies, and other applications.
