Sweeping the lean angle can increase movie thickness uniformity and sidewall coverage while also steering clear of significant energy-reflected neutral species for crucial processes.
In-situ optical monitoring and Manage is on the market as a result of Angstrom’s optical monitoring & Regulate package.
An optional cryogenic pump enhances base force and pumping velocity and will be isolated within the chamber throughout reactive processes with oxygen.
The dimensions, placement, and gear ratio of every World are optimized to provide the very best feasible movie thickness uniformity.

Variable angle levels allow for incredibly strong slender movie procedures. Nevertheless, certainly one of its biggest issues is reproducibility. The substrate is frequently set at an exceptionally oblique angle in relation to the supply, plus the movies are really delicate to the precision of the angle.
Angstrom Engineering® types and engineers Every Reticle® System to offer our associates from the optics Group a chance to develop the movies they need with great purity, density, and uniformity, all in the hugely repeatable and automated trend.
Our special style and design permits direct or oblique monitoring of the variable angle stage, removing the need for tooling elements or perhaps a witness glass changer. Find out more about the Optical Checking & Handle offer in this article.
IBSD processes can also employ a secondary ion resource for substrate cleaning and energetic guide, substrate heating for reactive deposition, As well as in-situ optical checking or ellipsometry for critical layer thickness termination.
All conventional Reticle® platforms involve an additional gridless finish-Hall ion source with hollow cathode neutralizer.
The deposition ion resource is directed towards a material concentrate on which has been optimized in each sizing and situation for the needed deposition geometry.
Self-aligned ion optics are configured specifically for the specified deposition prerequisites and geometry of your method.
Angstrom Engineering’s Reticle® systems provide a convert-important Resolution for people seeking to comprehend any optical design right into a higher-effectiveness movie.
A shuttered QCM Positioned close to the substrate supplies comments to the deposition amount and physical thickness of the increasing movie.
Considerate style on the Titanium for deposition processes ion beam concentrating optics confines the beam entirely to the world of your concentrate on, removing any possibility of contamination.
