Magnetron sputtering is a physical vapor deposition method that allows the deposition of various materials, including metals, oxides, ceramics and etc. by using a specially formed magnetic field applied to a diode sputtering target. The deposition rate, or the film formation rate, is an important parameter that measures the effectiveness of the magnetron sputtering machine....Continue Reading
An Overview of Magnetron Sputtering Magnetron sputtering, a physical vapor deposition (PVD) process, is a main thin film deposition method for manufacturing semiconductors, disk drives, CDs, and optical devices. Magnetron sputtering has the advantages of high speed, low temperature, and low damage. In this article, let’s take a look at the definition, working principle, and...Continue Reading
What are the Three Generations of Semiconductor Materials? The first generation of semiconductor material The first generation of semiconductor materials mainly refers to silicon (Si) and germanium (Ge) materials. In the 1950s, Ge dominated the semiconductor market and was mainly used in low-voltage, low-frequency, medium-power transistors and photodetectors. However, Ge semiconductor devices were inferior in...Continue Reading
Effect of Sputtering Target Purity on Large-Area Coating Production The requirement of the target quality for sputter coating is higher than that of the traditional materials industry. When the substrate enters the high vacuum coating chamber, if the sputtering target is not pure enough, under the action of the electric field and the magnetic field,...Continue Reading
Scandium nitride (ScN) is a metal nitride semiconductor. The crystal structure of ScN is generally rock salt and non-polar. However, the first principle calculation indicates that ScN may also have a wurtzite structure and can be made into Sc-IIIA-Nitride. The IIIA nitride refers to AlN, GaN, and InN, and the structure of the nitride is...Continue Reading
Titanium dioxide (TiO2) is a hard and chemically resistant oxide of titanium. Using TiO2 sputtering target can obtain good quality titanium dioxide films, which have been widely used in various applications due to their multiple interesting properties. The first half of this passage introduces some of the properties and applications of titanium oxide film, and the latter...Continue Reading
Definition of ITO Sputtering Target The full name of ITO is indium tin oxide, a composition of indium, tin, and oxygen with different proportions. The substance of ITO and ITO sputtering target is the same, the latter of which is actually a black-gray ceramic semiconductor formed by mixing indium oxide and tin oxide powder in...Continue Reading
Why do you need anti-reflection coating? Anti-reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses, which is good for one’s vision. When light passes through the front and back surfaces of the lens, it not only produces refraction but also produces reflection. This kind of reflected...Continue Reading
Almost all new sputter deposition equipment uses a powerful magnet to spiral the electrons to accelerate the ionization of the argon around the target, resulting in an increased probability of collision between the sputtering target and the argon ions, and thus the sputtering rate is increased. Generally, most metal films uses DC sputtering, while non-conductive...Continue Reading
