Nowdays, mobile phones have become the most indispensable thing for the public, and mobile phone displays are becoming more and more high-end. Comprehensive screen design and small bangs design are an important step in making mobile phone LCD. Do you know what it is— Coating: use magnetron sputtering technology to sputter metal molybdenum from molybdenum target to liquid crystal glass. Here below, this article will give you a specific introduction.
Sputtering, as an advanced technique for preparing thin film data, has two characteristics of “high speed” and “low temperature”. It uses the ions produced by the ion source to accelerate the aggregation and integration of high-speed ion flow in vacuum, bombard the solid surface, and the ions exchange kinetic energy with the atoms on the solid surface, so that the atoms on the solid surface leave the target and deposit on the surface of the substrate, and then form a nano (or micron) film. The shelled solid is the data of thin films deposited by sputtering, which is called sputtering target.
In the electronics industry, molybdenum sputtering targets are mainly used for flat-panel displays, electrodes and wiring materials of thin-film solar cells, and barrier materials of semiconductors.
These are based on the high melting point, high conductivity, low specific impedance, good corrosion resistance and good environmental protection function of molybdenum.
Previously, the wiring data of flat panel display was mainly chromium, but with the large-scale and high-precision of flat panel display, data smaller than impedance is more and more needed. In addition, environmental protection is also a necessary consideration. Molybdenum has the advantage that the specific impedance and film stress are only 1 / 2 of that of chromium, and there is no problem of environmental pollution, so it has become one of the materials of sputtering target for flat panel display.
In addition, the use of molybdenum in LCD components can greatly improve the functions of LCD in brightness, contrast, color and service life. TFT-LCD is one of the most important applications of molybdenum sputtering target in flat panel display industry.
Market research shows that the next few years will be the peak of LCD development, with an annual growth rate of about 30%. With the development of LCD, the consumption of LCD sputtering target is also growing rapidly, with an annual growth rate of about 20%.
In addition to the flat panel display profession, with the development of new energy profession, the application of molybdenum sputtering target in thin-film solar photovoltaic cells is also increasing.
The molybdenum sputtering target is mainly sputtered to form the electrode layer of CIGS (copper indium gallium selenium) thin film battery. Mo is at the bottom of the solar cell. As the back touch of the solar cell, it plays a very important role in the nucleation, growth and description of CIGS thin film crystals.
