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.

FAQ
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.
