Layer termination from ellipsometric data is absolutely built-in into Aeres®. A variety of multi-wavelength and spectroscopic ellipsometry remedies are offered While using the ion beam sputter deposition procedure.
In-situ optical checking and control is offered through Angstrom’s optical checking & Manage package deal.
Goal rotation and carousel indexing each have torque feeling, blocking any procedure difficulties due to slips or jams in rotation.
In-situ ellipsometry supplies critical info on the overall performance of the optical film though it truly is becoming deposited.
Our Reticle® ion beam sputter deposition programs are created and engineered to make precise optical movies of the highest purity, density, and steadiness.
Variable angle stages let for really effective thin film tactics. Having said that, considered one of its largest challenges is reproducibility. The substrate is often set at a really oblique angle in relation to your source, and the movies are very delicate towards the precision of this angle.
Angstrom Engineering® models and engineers each Reticle® platform to provide our companions while in the optics Group the ability to develop the movies they need to have with great purity, density, and uniformity, all inside of a extremely repeatable and automatic vogue.
Generally, a QCM is utilized to calibrate an First deposition amount before finishing the layer thickness less than time control with a fixed beam current. Shuttering the crystal will greatly prolong its operating life time throughout extended processes or on methods with a load lock.
In conjunction with sample rotation, the variable angle stage that may be utilized for Reticle® provides for in-developed angular motion with the deposition flux.
The IBSD process generates a really energetic flux of deposition substance, resulting in films with improved density, hardness, and surface roughness when compared with those deposited by evaporation High-purity metal products processes.
The deposition ion source is directed towards a fabric goal that has been optimized in both equally sizing and situation to the essential deposition geometry.
Self-aligned ion optics are configured specifically for the desired deposition needs and geometry of one's system.
Angstrom Engineering’s Reticle® units give a flip-key Resolution for those wanting to understand any optical style into a substantial-efficiency movie.
Dynamic uniformity shaping is realized employing a flux correction shield between the deposition source plus the substrate.
Thoughtful structure in the ion beam focusing optics confines the beam entirely to the area of the goal, removing any chance of contamination.
