Layer termination from ellipsometric facts is totally built-in into Aeres®. Many different multi-wavelength and spectroscopic ellipsometry methods can be found Along with the ion beam sputter deposition system.
IBSD usually takes put in a very substantial vacuum environment, minimizing noble fuel inclusion from the deposited film and improving the environmental steadiness on the coating.
An optional cryogenic pump enhances foundation tension and pumping velocity and can be isolated in the chamber through reactive processes with oxygen.
In-situ ellipsometry offers essential info on the effectiveness of the optical movie though it is currently being deposited.
Our Reticle® ion beam sputter deposition techniques are intended and engineered to build specific optical films of the best purity, density, and security.
Variable angle phases make it possible for for pretty potent slender film methods. On the other hand, considered one of its major troubles is reproducibility. The substrate is usually set at an incredibly oblique angle in relation to your supply, as well as films are really sensitive to your precision of this angle.
Angstrom Engineering® models and engineers Each and every Reticle® System to provide our partners while in the optics community the opportunity to create the films they want with outstanding purity, density, and uniformity, all in a highly repeatable and automated fashion.
Usually, a QCM is utilized to calibrate an Preliminary deposition level prior to completing the layer thickness beneath time Regulate with a hard and fast beam recent. Shuttering the crystal will greatly extend its running life time in the course of long processes or on techniques that has a load lock.
In addition to sample rotation, the variable angle stage that may be utilized for Reticle® supplies for in-designed angular motion in the deposition flux.
The IBSD course of High-purity metal products action makes a hugely energetic flux of deposition content, bringing about films with improved density, hardness, and surface roughness as compared to These deposited by evaporation processes.
The deposition ion source is directed towards a fabric focus on that has been optimized in both sizing and placement for the demanded deposition geometry.
Self-aligned ion optics are configured especially for the specified deposition necessities and geometry of the approach.
Angstrom Engineering’s Reticle® programs provide a switch-important Remedy for the people trying to recognize any optical design right into a higher-functionality movie.
A shuttered QCM located close to the substrate delivers comments over the deposition fee and physical thickness of the growing movie.
Each individual axis of motion is controlled by means of Aeres® utilizing precision servo motors, providing a lot better than 0.1 levels of positional accuracy. Front side infrared heating bulbs tilt Along with the stage to offer a reliable temperature profile for reactive processes.
