# 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

## Usage Guidelines

### ALD Process Control

1. **Saturation Studies**
   - Vary pulse times
   - Identify saturation dose
   - Optimize purge times

2. **Process Window**
   - Determine ALD window
   - Optimize temperature
   - Monitor GPC stability

3. **Film Quality**
   - Characterize uniformity
   - Measure conformality
   - Assess impurity levels

## Process Integration

- Thin Film Deposition Process Optimization
- Nanodevice Integration Process Flow
