13 Facts About Plasma etching

Plasma etching is a form of plasma processing used to fabricate integrated circuits.

Plasma etching is a high energetic condition in which a lot of processes can occur.

Key to develop successful complex Plasma etching processes is to find the appropriate gas etch chemistry that will form volatile products with the material to be etched as shown in Table 1.

Argon plasma etching has reported to enhance contact angle from 52 deg to 68 deg, and, Oxygen plasma etching to reduce contact angle from 52 deg to 19 deg for CFRP composites for bone plate applications.

For plasma etching to happen, the chamber has to be under low pressure, less than 100 Pa.
