Critical Control for Every Deposition Platform
PLD Systems
Holds back material flux during substrate temperature stabilization, ensuring clean epitaxial growth starts with sharp interfaces.
CVD Processes
Enables source conditioning and outgas purging before exposing the substrate, preventing contamination in CVD film stacks.
Thermal Evaporation
Gates the evaporation flux during source warm-up and conditioning, ensuring deposition only begins once the source has stabilized.
PVD & Sputtering
Acts as a fast-acting gate between target and substrate, enabling repeatable deposition cycles with consistent film properties.

Shutter Components & Features
1 Flux & Heat Control
- Physically blocks material flux and radiant heat between source and substrate
- Enables temperature stabilization before deposition begins
- Prevents uncontrolled film nucleation during heat-up phases
- Open/close timing directly governs deposited layer thickness
- Supports nanometer-precision thickness control across deposition workflows
2 Interface & Repeatability
- Delivers sharp, well-defined layer interfaces in multilayer film stacks
- Eliminates transitional contamination between sequential depositions
- Consistent open/close actuation for run-to-run reproducibility
- Reduces film thickness variation caused by source instability
- Critical for semiconductor, optical coating, and research applications
3 Vacuum Compatibility
- Fully compatible with high-vacuum and ultra-high vacuum (UHV) environments
- Low outgassing materials to prevent chamber or film contamination
- No adhesives or organic binders — safe for clean deposition processes
- Designed for continuous in-vacuum operation without performance degradation
- Integrates directly into BWS deposition chambers with standard fittings
4 Source Conditioning
- Allows source material outgassing and stabilization while substrate is protected
- Prevents initial contamination burst from reaching the growing film
- Essential for reactive sources, targets, and effusion cells
- Maintains source purity across repeated deposition cycles
- Compatible with PLD, PVD, CVD, and sputtering source geometries
