Functional Capabilities
- Plasma Process Optimization
- Dynamic impedance tuning for unstable plasma states in high-aspect-ratio etching (e.g., 3D NAND channels).
- Closed-loop control of ion density (>10¹⁰ ions/cm³) and electron temperature (1–10 eV).
- Advanced Fault Detection
- Arc suppression with <10 µs response time (critical for HBM/DRAM capacitor etching).
- Particulate monitoring via laser scattering (<0.1 µm sensitivity).
- Data Integration
- Multi-sensor fusion (pressure, temperature, RF harmonics) for machine learning-based process drift prediction.
- Compatible with Applied Materials BigLake™ analytics platform.
- Multi-Process Flexibility
- Supports dual-frequency CCP (Capacitively Coupled Plasma) and ICP (Inductively Coupled Plasma) modes.
- Recipe storage for >500 process steps (logic/memory transitions).
Typical Applications
- Advanced Etching
- Atomic-layer precise etching (ALE) for GAA (Gate-All-Around) transistor Fin formation.
- Low-k dielectric patterning in 3nm node BEOL (Back-End-of-Line) processes.
- Thin Film Deposition
- Plasma-enhanced ALD (Atomic Layer Deposition) for <1nm barrier layers.
- SiCOH low-k film curing in EUV lithography-compatible steps.
- Yield Management
- In-situ plasma uniformity mapping across 300mm wafers.
- Rogue chamber condition monitoring for preventive maintenance.
Critical Notes:
- The DPEM-440A likely operates within cluster tools like the Centura® or Producer® GT platforms.
- Subcomponent P/N 4022.455.16371 may indicate a country-specific variant or calibration kit.
- Always verify compatibility with host systems (e.g., AMAT Endura®, Tetra™).
Safety Requirements:
- Requires periodic calibration (6-month cycle recommended).
- Only trained personnel should handle HV connections and plasma-facing components.
