Layer termination from ellipsometric facts is entirely integrated into Aeres®. A variety of multi-wavelength and spectroscopic ellipsometry answers are available With all the ion beam sputter deposition technique.
In-situ optical monitoring and Manage is available by means of Angstrom’s optical checking & Regulate deal.
Target rotation and carousel indexing Just about every have torque feeling, preventing any system troubles as a consequence of slips or jams in rotation.
The scale, place, and gear ratio of every World are optimized to supply the absolute best achievable film thickness uniformity.
Our Reticle® ion beam sputter deposition programs are developed and engineered to produce specific optical movies of the highest purity, density, and balance.
Variable angle levels make it possible for for extremely highly effective skinny movie approaches. On the other hand, one among its biggest difficulties is reproducibility. The substrate is commonly established at a really oblique angle in relation to the source, as well as films are really delicate towards the precision of this angle.
Angstrom went to fantastic lengths to refine the tolerances of the tilt angle, bettering it from a variation of around a complete degree on non-Angstrom programs I’ve used to below 0.
Typically, a QCM is accustomed to calibrate an Original deposition fee just before completing the layer thickness underneath time control with a hard and fast beam present. Shuttering the crystal will substantially lengthen its functioning lifetime through long processes or on methods using a load lock.
IBSD processes might also hire a secondary ion source for substrate cleaning and energetic assist, substrate heating for reactive deposition, and in-situ optical monitoring or ellipsometry for critical layer thickness termination.
All regular Reticle® platforms include things like an additional gridless conclude-Corridor ion resource with hollow cathode neutralizer.
1 degree. Those incredibly narrow tolerances permit us to continuously generate really precise nanostructures. I'm able to say wholeheartedly the solution and service Angstrom Engineering® shipped has actually been wonderful.
Self-aligned ion optics are configured specifically for the specified deposition prerequisites and geometry within your approach.
A reduced-frequency neutralizer makes sure stable beam operation devoid of contamination from a conventional filament.
A shuttered QCM located near the substrate supplies opinions to the deposition amount and physical thickness of your increasing film.
Just about every axis of movement High-purity metal products is managed through Aeres® using precision servo motors, furnishing better than 0.one levels of positional accuracy. Entrance aspect infrared heating bulbs tilt Along with the stage to deliver a steady temperature profile for reactive processes.
