Plasma etching is a process that uses plasma to etch patterns onto a substrate, typically for semiconductor and microelectronics fabrication. The plasma creates reactive ions or radicals that remove material from the surface, leaving behind a desired pattern.
List if thermal evaporator:
- In reactive ion etching (RIE)
- Inductively coupled plasma (ICP)
- Atomic layer etching (ALE)
- Microwave Plasma Systems
Features:
- Precise Patterning: Allows for high-resolution etching of intricate patterns.
- Material Versatility: Can be used on a variety of materials, including metals, semiconductors, and insulators.
- High Control: Provides precise control over etch depth and uniformity.
- Clean Process: Plasma etching is a dry process, which reduces contamination compared to wet etching methods.
- Scalable: Suitable for both R&D and mass production environments.
- Advanced Applications: Ideal for the production of microelectronics, MEMS devices, and other precision components.
