Ald Process Controller

ALD Process Controller

Purpose

The ALD Process Controller skill provides comprehensive atomic layer deposition process control, enabling conformal thin film growth with atomic-level precision through optimized pulse sequences and in-situ monitoring.

Capabilities

• Precursor pulse/purge optimization
• Growth per cycle (GPC) characterization
• Film uniformity mapping
• Conformality assessment
• In-situ monitoring integration
• Multi-component film design
