Sweeping the tilt angle can increase film thickness uniformity and sidewall coverage although also preventing substantial energy-reflected neutral species for crucial processes.
In-situ optical checking and Management is offered by way of Angstrom’s optical monitoring & control deal.
An optional cryogenic pump improves foundation force and pumping speed and can be isolated with the chamber throughout reactive processes with oxygen.
The scale, place, and kit ratio of each and every Earth are optimized to offer the very best feasible film thickness uniformity.
We use cookies to ensure you possess the smoothest expertise navigating our web-site. This features accumulating non-personally identifiable facts during your searching session, like: which pages you search, what products you evaluation and how you communicate with Angstrom.
Variable angle levels allow for for really powerful slender movie tactics. On the other hand, among its biggest issues is reproducibility. The substrate is frequently established at an exceedingly oblique angle in relation on the source, and also the films are incredibly sensitive towards the precision of this angle.
Angstrom went to great lengths to refine the tolerances of the tilt angle, bettering it from the variation of around an entire diploma on non-Angstrom methods I’ve accustomed to fewer than 0.
Generally, a QCM is used to calibrate an First deposition amount ahead of finishing the layer thickness underneath time Command with a hard and fast beam latest. Shuttering the crystal will greatly increase its working life span during very long processes or on methods which has a load lock.
As well as sample rotation, the variable angle stage that is definitely utilized for Reticle® presents for in-created angular motion in the Titanium for deposition processes deposition flux.
All standard Reticle® platforms incorporate a further gridless conclude-Corridor ion resource with hollow cathode neutralizer.
The deposition ion supply is directed toward a cloth concentrate on that has been optimized in each dimension and posture with the essential deposition geometry.
Self-aligned ion optics are configured especially for the desired deposition prerequisites and geometry of your respective procedure.
A very low-frequency neutralizer makes sure stable beam operation without contamination from a traditional filament.
Dynamic uniformity shaping is obtained using a flux correction protect among the deposition supply and also the substrate.
Considerate design from the ion beam concentrating optics confines the beam totally to the world of the target, eradicating any risk of contamination.
