Magnesium oxide (MgO) substrate (single crystal) is widely used in many film technical fields. As for the production of magnetic film semiconductor film, optical film and the high-temperature superconducting films. It is currently an important industrial temperature superconducting thin films of single-crystal substrates.
Key Features:
MgO single crystal as the dielectric constant and loss microwave band is very small, and can obtain a large area substrate (diameter of 2 inches and larger), it is currently an important industrial HTS thin monocrystalline substrate world.
The main purpose:
For the production of magnetic thin film, a semiconductor film, optical film and the high-temperature superconducting thin film, can also be used for mobile communication equipment for making superconducting devices such as microwave filters.
