Sweeping the lean angle can make improvements to movie thickness uniformity and sidewall protection though also preventing high Electrical power-reflected neutral species for vital processes.
In-situ optical monitoring and Command is offered as a result of Angstrom’s optical checking & Management bundle.
Target rotation and carousel indexing Each and every have torque sense, preventing any method problems due to slips or jams in rotation.
In-situ ellipsometry offers vital information on the general performance of the optical movie whilst it truly is currently being deposited.
Our Reticle® ion beam sputter deposition techniques are made and engineered to produce precise optical movies of the best purity, density, and steadiness.
Variable angle levels permit for pretty impressive thin film tactics. Having said that, among its most important issues is reproducibility. The substrate is frequently established at an exceptionally oblique angle in relation towards the supply, plus the films are incredibly delicate for the precision of the angle.
Angstrom went to fantastic lengths to refine the tolerances of the lean angle, improving upon it from a variation of up to a complete diploma on non-Angstrom devices I’ve utilized to less than 0.
Our distinctive style permits direct or oblique checking with the variable angle phase, getting rid of the necessity for tooling components or simply a witness glass changer. Learn more with regards to the Optical Checking & Regulate offer here.
IBSD processes may also employ a secondary ion resource for substrate cleansing and energetic guide, substrate heating for reactive deposition, and in-situ optical monitoring or ellipsometry for critical layer thickness termination.
The IBSD course of action generates a hugely energetic flux of deposition material, resulting in movies with enhanced density, hardness, and area roughness compared to These deposited by evaporation processes.
The deposition ion source is directed toward a fabric target which has been optimized in each size and place for the necessary deposition geometry.
Self-aligned ion optics are configured especially for the specified deposition demands and geometry of your course of action.
A small-frequency neutralizer makes certain secure beam operation without the need of contamination from a standard filament.
A shuttered QCM located close to Tungsten materials for electronics the substrate presents comments about the deposition rate and Actual physical thickness of your growing film.
Thoughtful design and style in the ion beam concentrating optics confines the beam completely to the area in the concentrate on, getting rid of any risk of contamination.
