People are constantly looking down, making mobile phones the most necessary item for the general population. Mobile phone displays are also growing more and more high-end, with full-screen designs, narrow bezel designs, and an essential process needed to create LCD panels. Do you recognize it? — Coating, which involves sputtering metallic molybdenum from the molybdenum target onto the liquid crystal glass using magnetron sputtering technique. You will be fully introduced in the editor that follows.
Sputtering has two features that make it a cutting-edge thin film material preparation technique: "high speed" and "low temperature." It bombards the solid surface with high-speed ions generated by the ion source and exchanges kinetic energy with the atoms there, causing the solid surface atoms to flee the target and deposit on the surface of the substrate to form a nanometer (or micron) film. The material bombarded is a substance deposited using the sputtering technique, and is referred to as the sputtering target.
Molybdenum sputtering targets are primarily utilized in the electronics industry for semiconductor barrier materials, thin-film solar cell electrodes, and flat-panel displays.
The high melting point, high conductivity, low specific impedance, superior corrosion resistance, and outstanding environmental performance of molybdenum serve as the foundation for these.
In the past, flat-panel displays were mostly wired with chromium, but as their size and accuracy rise, it becomes more and more necessary to use materials with lower specific impedance. Environmental protection is another concern that needs to be taken into account. Molybdenum has been chosen as one of the materials for the sputtering target of the flat panel display because its specific impedance and film stress are only half of those of chromium's and it has no environmental pollution issues.
Moreover, LCD components contain molybdenum, which can significantly enhance the brightness, contrast, color, and life of liquid crystal displays. The TFT-LCD field is one of the key commercial applications for molybdenum sputtering targets in the flat panel display industry.
According to market research, LCD development will reach its peak in the coming years, with an average annual growth rate of roughly 30%.
With the advancement of LCD, the need for LCD sputtering targets has also increased quickly, at a rate of roughly 20% every year.
With the growth of the new energy sector, molybdenum sputtering targets are being used more and more in thin-film solar photovoltaic cells in addition to the flat panel display business.
The electrode layer of CIGS (copper, indium, gallium, selenium) thin film batteries is typically formed by sputtering, and the molybdenum sputtering target is employed for this purpose.
Mo is situated at the solar cell's base among them. As the solar cell's back contact, it is crucial to the formation, development, and shape of CIGS thin film crystals.
