Etching

Etching is a broad term that is used to describe the removal of material from your sample. The sub categories may be helpful for narrowing down your search, and be aware that there may be more than one technique and/or tool that could be used for your process.

Dry etching uses gaseous chemistries and plasma energy to etch materials from the sample.
Wet etching uses liquid chemistries to etch materials from samples.
Vapor etching uses HF Vapor to etch materials. It is primarily used to etch structures that would be damaged during the rinse and dry process in a standard wet etch.
