Sweeping the tilt angle can boost film thickness uniformity and sidewall protection when also preventing substantial Strength-reflected neutral species for important processes.
In-situ optical checking and control is obtainable via Angstrom’s optical monitoring & Manage offer.
An optional cryogenic pump improves foundation pressure and pumping speed and may be isolated from your chamber throughout reactive processes with oxygen.
The scale, placement, and gear ratio of each and every planet are optimized to deliver the absolute best attainable movie thickness uniformity.
Our Reticle® ion beam sputter deposition systems are designed and engineered to create exact optical movies of the highest purity, density, and security.
Variable angle phases allow for very powerful slim film methods. Having said that, one of its largest issues is reproducibility. The substrate is often set at an extremely oblique angle in relation towards the supply, plus the movies are very sensitive towards the precision of this angle.
Angstrom Engineering® models and engineers Every Reticle® platform to offer our partners during the optics Neighborhood the chance to make the movies they need with excellent purity, density, and uniformity, all inside of a remarkably repeatable and automated trend.
Normally, a QCM is utilized to calibrate an Original deposition price before completing the layer thickness beneath time Handle with a set beam current. Shuttering the crystal will dramatically prolong its functioning life time through Titanium for deposition processes very long processes or on programs which has a load lock.
Together with sample rotation, the variable angle stage that may be utilized for Reticle® presents for in-developed angular motion in the deposition flux.
The IBSD method results in a really energetic flux of deposition product, resulting in films with improved density, hardness, and area roughness when compared with People deposited by evaporation processes.
The deposition ion supply is directed towards a fabric target that has been optimized in equally dimension and situation for your needed deposition geometry.
Personal purchasing transactions with Angstrom as well as your purchaser account are subject to their own information retention policies. In these instances, you have presented us authorization to make use of your order details to better current and product our merchandise.YesPrivacy Plan
A very low-frequency neutralizer assures steady beam Procedure without the need of contamination from a standard filament.
Dynamic uniformity shaping is reached employing a flux correction shield amongst the deposition resource and also the substrate.
Thoughtful design of your ion beam concentrating optics confines the beam totally to the region with the focus on, reducing any danger of contamination.
