Vacuum Coating with Pressure Control

PVD and ALD: Control pressures and flows into vacuum processes

Uneven coating quality and poor repeatability result from fluctuations in vacuum chamber pressure. Achieve faster, more precise controls of neutral and reactive gases using an Alicat pressure controller. Using the pressure controller non-reactive gases and using Alicat mass flow controllers for reactive gases improves uniformity and success in plasma vapor deposition (PVD).
App Note

Sputtering Flow Control

Sputtering Flow Control with Vacuum

Controlling the amount of plasma gas within a sputtering chamber is crucial. Fast response times, fine flow resolution and accurate control of the partial pressures of reactive gasses prevent target poisoning, while improving uniformity. 25 to 50 millisecond control times make the difference.
App Note

External Ion Gauge Vacuum Control System

Coating: External Sensor Vacuum Control System

Upstream vacuum control that is compatible with many vacuum gauges, including Capacitance Manometers and Ion Gages. This method obtains lightning-fast control of vacuum, using a special configuration of an Alicat single-valve pressure controller.
App Note

IVC Integrated Vacuum Controllers

The IVC Series vacuum controller provides an alternative to expensive downstream vacuum valves. In comparison, downstream valves are slow to respond and difficult to operate.

The IVC incorporates vacuum sensors capable of operating accurately to low millitorr ranges. The sensor can be plumbed to a downstream location through a port, or may be configured in-line with the control valve and flow. By integrating the sensor in the controller, users save parts and costs, while enjoying well-calibrated responses.

PC-EXTSEN/PCR-EXTSEN External Sensor Series

Alicat PC-EXTSEN-series pressure controller with external sensor connector
The PC-EXTSEN Series connects to an external pressure transducer via a dedicated connector and cable, allowing it to control flow at its location based on conditions at a location downstream, through serial or analog communication from the sensor. The PC-EXTSEN does not have an internal pressure sensor of its own, instead relying upon the customer-supplied sensor to provide pressure readings. This series is especially useful for vacuum coating processes that employ vacuum gauges.
