Etching Method

Residual Layer Etching

Any issues regarding residual layers have been address by good understanding of how to control removal rates and process optimization.

Thin resist

SCIVAX can offer a solution even in the case where resist layers are too thin (i.e. with respect to the thickness of the target film and etch selectivity.

Etch Profile Control

Etching wall angle can be controlled.
