Surface Preparation

Etch control

We offer the most efficient and cost effective techniques for monitoring and controlling your Clean and Etch processes

Semiconductor manufacturing involves many surface preparation and cleaning steps, as well as etch steps, whereby layers of materials have to be selectively and precisely removed. In order to avoid ineffective underetch or damaging overetch, tight, automated process monitoring and control is necessary for critical Clean and Etch processes.
