scia Batch 350 – Biocompatible coatings on 3D-substrates

by Plasma Enhanced Chemical Vapor Deposition (PECVD)

scia Batch 350

The scia Batch 350 is designed for homogeneous coating of several 3‑dimensional shaped substrates in one batch. Typical applications are biocompatible films for medical objects.

The scia Batch 350 uses a RF parallel plate arrangement with rotation of each substrate for a homogeneous coating of all sides. The system is also available with an additional DC bias applied to the substrate holder.
