Layer termination from ellipsometric knowledge is totally built-in into Aeres®. Various multi-wavelength and spectroscopic ellipsometry remedies can be found With all the ion beam sputter deposition method.
In-situ optical monitoring and Manage is available through Angstrom’s optical monitoring & Command bundle.
An optional cryogenic pump increases foundation pressure and pumping velocity and might be isolated in the chamber all through reactive processes with oxygen.
The size, posture, and kit ratio of each Earth are optimized to provide the absolute best attainable film thickness uniformity.
Our Reticle® ion beam sputter deposition units are designed and engineered to build precise optical films of the very best purity, density, and steadiness.
Variable angle levels allow for extremely effective thin movie methods. Having said that, amongst its most important difficulties is reproducibility. The substrate is frequently set at an exceedingly oblique angle in relation to your supply, along with the films are extremely sensitive for the precision of this angle.
Angstrom went to terrific lengths to refine the tolerances of the tilt angle, bettering it from the variation of up to a full diploma on non-Angstrom devices I’ve accustomed to lower than 0.
Our exclusive structure permits direct or indirect checking on the variable angle phase, removing the need for tooling components or perhaps a witness glass changer. Find out more with regard to the Optical Checking & Handle package right here.
IBSD processes could also use a secondary ion supply for substrate cleaning and energetic guide, substrate heating for reactive deposition, As Molybdenum evaporation sources well as in-situ optical monitoring or ellipsometry for significant layer thickness termination.
The IBSD method produces a remarkably energetic flux of deposition substance, leading to films with improved density, hardness, and floor roughness when compared with People deposited by evaporation processes.
The deposition ion source is directed toward a material target that has been optimized in equally size and place to the demanded deposition geometry.
Self-aligned ion optics are configured especially for the desired deposition demands and geometry of the approach.
Angstrom Engineering’s Reticle® techniques provide a flip-key Option for the people looking to comprehend any optical layout into a substantial-overall performance movie.
A shuttered QCM located near the substrate supplies opinions within the deposition rate and Actual physical thickness with the developing film.
Considerate style of your ion beam concentrating optics confines the beam solely to the area with the concentrate on, eliminating any possibility of contamination.
