Tungsten Sputtering Target For Magnetron Sputtering Coating
1. Description Of Tungsten Sputtering Target For Magnetron Sputtering Coating:
The tungsten layer is part of the thin-film transistors of TFT-LCD screens. They are used when large-screen formats, extremely high image clarity, and optimized contrast ratios are required. Tungsten targets are also used in the microelectronics industry, for example to form coatings in frequency filters (surface acoustic wave filters (SAW), bulk acoustic wave filters (BAW)). Other applications for tungsten targets include diffusion barriers made of tungsten nitride, conductor tracks in microelectronic components, and reactive sputtered transparent layers made of tungsten oxide for OLED displays and electrochemical applications.
In the magnetron sputtering process (PVD process), the sputtering target releases tiny metal particles that deposit on the material to be coated (ie the substrate), forming a thin film. This coating process is economical and fast, in which all materials must meet the strictest quality standards.
