This acts as an insulating film, preventing leakage current between circuits, and at the same time acting as a dielectric, and acts as a protective film for the wafer in subsequent processes. The thermal oxidation method is mainly used as a method of coating an oxide film, and in this process, the technology has developed in a way to increase the respective oxidation efficiency.


 There is a report that a general ZnO semiconductor exists as an n-type or that a p-type transfer characteristic is made in the presence of no-wire ZnO.

When the ZnO thin film was deposited, crystallinity appeared, and it can be seen that when the heat treatment was performed, oxygen cavities were generated and changed to amorphous characteristics.
