Caused by the chemical properties of the reaction with oxygen when the Pt atom in oxygen plasma etching process will affect the shape of the micro-pattern with each pattern slightly swollen.
The chemical properties of Pt reacts with the oxygen atom of oxygen plasma etching processes can influence its shape. micro-pattern The swell of each pattern a little.
Due to the chemical properties of Pt when reacted with oxygen atom in the process oxygen plasma etching will affect the shape of the micro-pattern. The swelling of each pattern slightly.
