Product Name: ESC (Electrostatic Chuck) Component / Shield
Product Description: A critical component associated with electrostatic chuck assemblies, used for clamping wafers during processing. It may be a shield, insulator, or structural part of the ESC.
Technical Specifications:
- Material: High-purity ceramic or thermally conductive composite.
Detailed content
- Design: Profile-machined to mate with specific ESC and electrode geometries.
- Dielectric Properties: Tailored dielectric constant for optimal chucking performance.
- Thermal Conductivity: High thermal conductivity for efficient heat transfer to/from the wafer.
Functional Features:
- Ensures uniform electrostatic field distribution for consistent wafer clamping.
- Provides electrical isolation between the chuck electrode and process plasma.
- Resists thermal stress and chemical attack during high-temperature processing.
- Contributes to temperature uniformity across the wafer surface.
Application Scenarios:
- Integrated into ESC assemblies in PVD, Etch, and CVD chambers.
- Critical for maintaining wafer temperature and position in advanced 300mm/450mm processing.
