Sweeping the tilt angle can boost film thickness uniformity and sidewall coverage when also avoiding superior energy-mirrored neutral species for essential processes.
In-situ optical checking and control is out there by way of Angstrom’s optical checking & control bundle.
An optional cryogenic pump enhances foundation tension and pumping pace and will be isolated within the chamber in the course of reactive processes with oxygen.
The dimensions, position, and gear ratio of each planet are optimized to provide the absolute best achievable film thickness uniformity.
Our Reticle® ion beam sputter deposition methods are built and engineered to create exact optical movies of the best purity, density, and security.
Variable angle stages allow for for pretty impressive thin movie methods. Nevertheless, considered one of its biggest troubles is reproducibility. The substrate is frequently set at a really oblique angle in relation to your supply, along with the films are quite sensitive on the precision of this angle.
Angstrom Engineering® styles and engineers Every single Reticle® platform to deliver our associates from the optics Local community a Medical-grade metals supplier chance to create the movies they will need with great purity, density, and uniformity, all within a really repeatable and automatic fashion.
Normally, a QCM is accustomed to calibrate an Original deposition level prior to completing the layer thickness under time Manage with a hard and fast beam present. Shuttering the crystal will considerably extend its operating life span throughout extended processes or on techniques having a load lock.
IBSD processes may also make use of a secondary ion supply for substrate cleaning and energetic assist, substrate heating for reactive deposition, and in-situ optical checking or ellipsometry for critical layer thickness termination.
All regular Reticle® platforms incorporate yet another gridless close-Corridor ion source with hollow cathode neutralizer.
The deposition ion source is directed towards a material target that has been optimized in each dimensions and place for your essential deposition geometry.
Self-aligned ion optics are configured especially for the desired deposition necessities and geometry of your respective course of action.
A low-frequency neutralizer assures stable beam operation without the need of contamination from a conventional filament.
Dynamic uniformity shaping is attained employing a flux correction protect involving the deposition source and also the substrate.
Thoughtful layout from the ion beam focusing optics confines the beam fully to the world of your concentrate on, removing any possibility of contamination.
