Sweeping the lean angle can improve film thickness uniformity and sidewall coverage while also preventing large Strength-reflected neutral species for important processes.
In-situ optical checking and Handle is accessible via Angstrom’s optical monitoring & control package.
Focus on rotation and carousel indexing each have torque sense, protecting against any method issues due to slips or jams in rotation.
In-situ ellipsometry gives important info on the functionality of the optical movie whilst it can be remaining deposited.
Our Reticle® ion beam sputter deposition programs are intended and engineered to generate precise optical films of the very best purity, density, and balance.
Variable angle stages enable for extremely effective thin film approaches. On the other hand, certainly one of its biggest problems is reproducibility. The substrate is commonly set at an exceedingly oblique angle in relation to your supply, and also the movies are certainly sensitive into the precision of the angle.
Angstrom Engineering® layouts and engineers Just about every Reticle® System to supply our associates while in the optics community the opportunity to produce the films they will need with exceptional purity, density, and uniformity, all in the hugely repeatable and automatic style.
Generally, a QCM is utilized to calibrate an Preliminary deposition fee in advance of finishing the layer thickness below time control with a set beam existing. Shuttering the crystal will drastically prolong its working life time through long processes or on units by using a load lock.
IBSD processes might also utilize a secondary ion resource for substrate cleansing and energetic Tantalum sputtering targets support, substrate heating for reactive deposition, As well as in-situ optical monitoring or ellipsometry for crucial layer thickness termination.
All common Reticle® platforms consist of an extra gridless close-Hall ion resource with hollow cathode neutralizer.
The deposition ion source is directed towards a cloth concentrate on that has been optimized in equally dimensions and situation with the essential deposition geometry.
Self-aligned ion optics are configured specifically for the specified deposition specifications and geometry of the procedure.
A low-frequency neutralizer makes sure steady beam Procedure devoid of contamination from a conventional filament.
Dynamic uniformity shaping is attained employing a flux correction defend involving the deposition resource plus the substrate.
Each axis of movement is managed via Aeres® working with precision servo motors, supplying much better than 0.one levels of positional accuracy. Entrance side infrared heating bulbs tilt With all the stage to supply a constant temperature profile for reactive processes.
