# EBL Process Controller

## Purpose

The EBL Process Controller skill provides comprehensive electron beam lithography process control, enabling high-resolution nanopatterning through dose optimization, proximity effect correction, and critical dimension control.

## Capabilities

- Pattern design and fracturing
- Dose optimization and modulation
- Proximity effect correction (PEC)
- Alignment and overlay control
- Resist processing optimization
- Critical dimension (CD) control

## Usage Guidelines

### EBL Process Control

1. **Pattern Preparation**
   - Design in CAD software
   - Fracture into write fields
   - Apply beam step size

2. **Dose Optimization**
   - Run dose matrices
   - Apply PEC algorithms
   - Account for pattern density

3. **Process Integration**
   - Optimize resist thickness
   - Control development conditions
   - Verify feature dimensions

## Process Integration

- Nanolithography Process Development
- Nanodevice Integration Process Flow
