Sweeping the lean angle can strengthen movie thickness uniformity and sidewall coverage when also avoiding substantial Vitality-mirrored neutral species for important processes.
In-situ optical checking and control is offered via Angstrom’s optical checking & Management package.
An optional cryogenic pump increases base force and pumping velocity and might be isolated from the chamber throughout reactive processes with oxygen.
The dimensions, placement, and gear ratio of each and every Earth are optimized to provide the very best attainable movie thickness uniformity.
Our Reticle® ion beam sputter deposition systems are built and engineered to make precise optical movies of the highest purity, density, and stability.
Variable angle levels enable for very powerful slender film methods. Having said that, among its greatest problems is reproducibility. The substrate is frequently set at an exceedingly oblique angle in relation into the supply, as well as films are quite sensitive towards the precision of the angle.
Angstrom Engineering® designs and engineers each Reticle® platform to supply our partners during the optics Group the chance to develop the movies they require with great purity, density, and uniformity, all in a highly repeatable and automatic trend.
Frequently, a QCM High-purity metal products is used to calibrate an Preliminary deposition rate before completing the layer thickness beneath time Manage with a set beam present. Shuttering the crystal will substantially lengthen its functioning life time through very long processes or on devices with a load lock.
IBSD processes may also make use of a secondary ion resource for substrate cleansing and energetic assist, substrate heating for reactive deposition, and in-situ optical checking or ellipsometry for important layer thickness termination.
All conventional Reticle® platforms include a further gridless close-Corridor ion source with hollow cathode neutralizer.
one degree. Those people incredibly slender tolerances allow for us to regularly develop extremely exact nanostructures. I can say wholeheartedly the merchandise and service Angstrom Engineering® shipped is wonderful.
Self-aligned ion optics are configured especially for the specified deposition needs and geometry of your respective process.
A reduced-frequency neutralizer makes sure stable beam Procedure with out contamination from a conventional filament.
Dynamic uniformity shaping is reached utilizing a flux correction shield between the deposition resource along with the substrate.
Thoughtful design from the ion beam focusing optics confines the beam totally to the area of the focus on, removing any hazard of contamination.
