More details of the MgO wafer
Magnesium oxide (MgO) is a superior choice for monocrystalline substrates, extensively used in the fabrication of ferroelectric, magnetic, optical, and high-temperature superconducting thin films.
MgO stands out for its low dielectric constant and minimal loss in the microwave frequency range, making it an ideal material for high-performance applications.
The ability to produce large-area substrates, including those with 2 inches and beyond diameters, solidifies MgO’s role as a crucial substrate in the high-temperature superconducting film industry.
This material is particularly beneficial in the development of high-temperature superconducting microwave filters and other essential devices for mobile communication systems.
Our process involves using high-purity MgO crystals, grown to approximately 2"x2"x1", which are then refined through a specialized chemical mechanical polishing technique.
This method yields substrates of exceptional quality with atomically smooth surfaces, all while maintaining cost-effectiveness.

1. Q: Can MgO wafers be doped?
A: Yes, MgO wafers can be doped with various elements to modify their properties, such as altering their optical or electrical characteristics. However, undoped MgO is most commonly used in many applications.
2. Q: Are there any specific environmental considerations when using MgO wafers?
A: MgO wafers are chemically stable and resistant to most environmental factors; however, they should be kept in a controlled environment to prevent surface contamination or moisture absorption, which could affect their performance in precision applications.
