Sweeping the tilt angle can increase movie thickness uniformity and sidewall coverage even though also steering clear of higher Electricity-mirrored neutral species for vital processes.
In-situ optical monitoring and Manage is available by Angstrom’s optical checking & Command offer.
Goal rotation and carousel indexing Just about every have torque sense, stopping any course of action troubles as a consequence of slips or jams in rotation.
The size, situation, and equipment ratio of every Earth are optimized to offer the best possible achievable movie thickness uniformity.
Our Reticle® ion beam sputter deposition techniques are built and engineered to generate precise optical films of the highest purity, density, and steadiness.
Variable angle phases let for pretty powerful slender movie procedures. Even so, one of its biggest challenges is reproducibility. The substrate is usually set at an exceedingly oblique angle in relation for the source, and the films are quite delicate for the precision of this angle.
Angstrom went to fantastic lengths to refine the tolerances of the lean angle, strengthening it from the variation of as many as a full diploma on non-Angstrom systems I’ve utilized to below 0.
Our unique structure permits direct or oblique checking on the variable angle phase, eradicating the need for tooling things or even a witness glass changer. Find out more with regard to the Optical Monitoring & Control offer here.
IBSD processes can also utilize a secondary ion source for substrate cleaning and energetic aid, substrate heating for reactive deposition, As well as in-situ optical monitoring or ellipsometry for vital layer thickness termination.
All conventional Reticle® platforms consist of an extra gridless stop-Hall ion source with hollow cathode neutralizer.
The deposition ion resource is directed toward a fabric concentrate on that has been optimized in equally sizing and place with the expected deposition geometry.
Unique obtaining transactions with Angstrom along with your consumer account are Zirconium and niobium supply issue to their own personal knowledge retention insurance policies. In this sort of circumstances, you've provided us permission to make use of your buy data to better existing and design our solution.YesPrivacy Policy
Angstrom Engineering’s Reticle® techniques offer a transform-essential Resolution for all those aiming to understand any optical structure into a substantial-general performance film.
Dynamic uniformity shaping is obtained using a flux correction protect involving the deposition source plus the substrate.
Considerate style and design in the ion beam focusing optics confines the beam fully to the region of the target, doing away with any threat of contamination.
