Layer deposition of metal and dielectric layers using magnetron sputtering and PECVD.


We offer magnetron sputtering of metal and dielectric layers. The PVD system is ideal for both single processes for R&D and small production runs. The system allows up to four materials to be deposited sequentially without removing the sample from the vacuum chamber. Two sputtering modes (RF and DC) allow dielectric and metal layers to be fabricated. Reactive sputtering in a nitrogen and oxygen atmosphere is also possible.

Plasma-Enhanced Chemical Vapour Deposition (PECVD) processes for applications in nanoelectronics, photonics, micromechanics, passivation, encapsulation, and masking. PECVD of silicon oxide, silicon nitrides and silicon oxynitrides with adjustable refractive index. Dielectric multilayer deposition is available.
