What is the role of molybdenum target in the field of mobile phone LCD screen?

Jun 23, 2020

In today's society, there are bow heads everywhere. Mobile phones have become an indispensable part of the public, and mobile phone displays are also getting higher and higher. Screen design, small bangs design, and the important steps required to make mobile phone LCD screen, do you know what is it? ---Molybdenum was sputtered from molybdenum target to liquid crystal glass by magnetron sputtering

Sputtering, as an advanced thin film preparation technology, has two major points: high speed and low temperature. It uses the ions produced by ion source to accelerate the aggregation of high-speed ion current in vacuum, bombard the solid surface, and exchange kinetic energy between the ions and 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, thus forming nano (or micron) films. The bombarded solid is the material of thin film deposited by sputtering method, which is called sputtering target.

In the electronic industry, molybdenum sputtering targets are mainly used as electrical and wiring materials for flat panel displays, thin film solar cells and semiconductor barrier materials.

These are based on molybdenum's high melting point, high conductivity, low specific impedance, good corrosion resistance and good environmental performance.

n the past, the wiring material of flat panel display was mainly chromium, but with the large-scale and high-precision of flat panel display, the material with smaller specific impedance is more and more needed. In addition, environmental protection must be considered. However, molybdenum has the advantages of only 1 / 2 of the specific impedance and membrane stress of chromium, and there is no environmental pollution problem. Therefore, molybdenum has become one of the sputtering target materials for planar display.
