Plasma etching


Plasma etching is used to roughen a surface, on the microscopic scale. The surface of the component is etched with a reactive process gas.Material is precisely sputtered off, converted to the gas phase and pumped away via the vacuum system. The surface area is greatly increased, making the material easily wettable. Etching is used before printing, gluing and painting and is particularly useful for processing of e.g. POM and PTFE, which cannot otherwise be printed on or bonded.

What is plasma etching?

Plasma etching is used to make the surface of a particular material microscopically rougher. The surface is etched with a reactive process gas. Material is bombed away from the surface very precisely, converted into a gas phase and then removed via a vacuum pump. This increases the surface area and makes it easier to moisten.

What is reactive ion etching?

Reactive Ion Etching (RIE) provides an energetic and directed flux of reactive ions that bombard the surface. This allows a pre-marked pattern to be etched away very accurately.

Different Plasma Etching Systems

An RIE electrode can optionally be installed on all our low-pressure plasma systems. As a result, we obtain a low-cost lab system for research into semiconductors or organic electronics. Possible applications for this are:

- Treatment of materials such as POM, PTFE, FEP, PFA (can otherwise not be printed or glued);
- PTFE components;
- Applying structures in silicone;
- Etching of light-resistant layer (PCB).
