Sweeping the tilt angle can boost film thickness uniformity and sidewall protection even though also staying away from higher Electrical power-reflected neutral species for essential processes.

In-situ optical monitoring and Regulate is obtainable by Angstrom’s optical checking & control offer.

Goal rotation and carousel indexing each have torque feeling, stopping any procedure issues on account of slips or jams in rotation.

The dimensions, position, and gear ratio of each planet are optimized to deliver the very best feasible film thickness uniformity.

Variable angle levels let for really strong skinny movie strategies. However, amongst its largest issues is reproducibility. The substrate is commonly established at an extremely oblique angle in relation for the source, plus the films are extremely delicate to the precision of the angle.

Angstrom Engineering® patterns and engineers Each individual Reticle® platform to deliver our partners inside the optics Neighborhood the opportunity to build the movies they will need with outstanding purity, density, and uniformity, all in a extremely repeatable and automatic manner.

Frequently, a QCM is utilized to calibrate an Preliminary deposition level ahead of finishing the layer thickness beneath time Regulate with a fixed beam existing. Shuttering the crystal will substantially prolong its working lifetime during prolonged processes or on systems having a load lock.

IBSD processes can also employ a secondary ion source for substrate cleansing and energetic help, substrate heating for reactive deposition, and in-situ optical monitoring or ellipsometry for critical layer thickness termination. 

All typical Reticle® platforms consist of an extra gridless close-Corridor ion resource with hollow cathode neutralizer.

The deposition ion resource is directed toward a cloth concentrate on which has been optimized in equally dimensions and place with the essential deposition geometry.

Self-aligned ion optics are configured specifically for the specified deposition specifications and geometry of your process.

A low-frequency neutralizer ensures steady beam operation without having contamination from a standard filament.

Dynamic uniformity shaping is obtained employing a flux correction shield between the deposition source along with the substrate.

Thoughtful design in the ion beam focusing optics confines the High-temperature metal components beam entirely to the area on the focus on, getting rid of any threat of contamination.
