Sweeping the tilt angle can improve film thickness uniformity and sidewall coverage even though also preventing higher Electrical power-reflected neutral species for crucial processes.
In-situ optical checking and Command is offered by means of Angstrom’s optical monitoring & Management package.
An optional cryogenic pump improves base stress and pumping speed and will be isolated from the chamber all through reactive processes with oxygen.
The size, placement, and equipment ratio of each Earth are optimized to deliver the best possible probable movie thickness uniformity.
We use cookies to ensure you provide the smoothest working experience navigating our website. This involves amassing non-personally identifiable facts in the course of your browsing session, for example: which webpages you look through, what products you critique And exactly how you communicate with Angstrom.
Variable angle levels allow for for quite powerful slim film approaches. Nevertheless, certainly one of its largest troubles is reproducibility. The substrate is usually established at an exceedingly oblique angle in relation towards the supply, plus the films are extremely delicate to your precision of the angle.
Angstrom went to terrific lengths to refine the tolerances of the lean angle, bettering it from the variation of as many as a full degree on non-Angstrom units I’ve used to lower than 0.
Frequently, a QCM is utilized to calibrate an Original deposition amount ahead of finishing the layer thickness below time Manage with a fixed beam existing. Shuttering the crystal will considerably prolong its functioning lifetime for the duration of very long processes or on units which has a load lock.
Coupled with High-purity metal products sample rotation, the variable angle stage which is utilized for Reticle® presents for in-built angular motion in the deposition flux.
All typical Reticle® platforms contain an additional gridless end-Hall ion resource with hollow cathode neutralizer.
1 diploma. All those beautifully slender tolerances permit us to repeatedly build incredibly exact nanostructures. I'm able to say wholeheartedly the products and service Angstrom Engineering® delivered continues to be amazing.
Self-aligned ion optics are configured specifically for the desired deposition necessities and geometry within your process.
A reduced-frequency neutralizer makes sure secure beam Procedure without contamination from a standard filament.
A shuttered QCM located near the substrate gives suggestions to the deposition charge and Actual physical thickness with the growing movie.
Considerate design and style of your ion beam focusing optics confines the beam totally to the realm of your target, eliminating any danger of contamination.
