Model-Free Adaptive Control for Semiconductor Processes & Tools

Semiconductor Apps
MFA Controller Types
MFA Benefits
Furnace - Multi-zone temperature control (low temp).
Deposition - Vacuum, gas flow, and pressure control.
Etching - Chemical composition, pH, and flow control.
CMP - Slurry flow and pressure control.
RTP - High-speed temp control.
ALD - low and vapor delivery.
Motion - High-speed adaptive & accurate motion control.

SISO MFA to replace PID and eliminate manual tuning.
Nonlinear MFA to control nonlinear processes.
MIMO MFA to control multivariable systems.
Anti-delay MFA to control processes with large time delays.
Feedforward MFA to deal with measurable disturbances.
MFA pH to control pH processes.

High yield achieved by fast and accurate control to reach setpoint.
Fast time-to-market for new product R&D since no process models are required.
Lower operating costs and longer up time by eliminating controller manual tuning.
Efficient use of tools due to minimal calibration and conditioning.
Best "cost of ownership" achieved when embedding MFA in your tools.
