EHT Semi Embeds Bird RF Sensors to Refine Plasma Control

Seattle-based EHT Semi is integrating Bird’s NIST-traceable RF measurement technology directly into its Orion Direct RF systems and custom waveform generators. By embedding these probes into the power infrastructure, the company aims to standardize voltage, current, and impedance data across the entire semiconductor manufacturing lifecycle, from initial calibration to fab production.

This technical synergy replaces fragmented monitoring with a unified reference point, allowing manufacturers to maintain consistent power regulation even during volatile plasma shifts. The integrated architecture achieves control within 2% of the set point, providing the stability necessary for high-precision process environments. EHT Semi CEO Timothy Ziemba noted that this approach closes the gap between factory calibration and real-world production monitoring.

Beyond immediate process stability, the high-fidelity data harvested by these probes offers a new layer of transparency for engineers. By surfacing granular power metrics at the equipment level, EHT Semi provides the raw input required for advanced diagnostics and AI-driven feedback loops. This shift supports faster process learning cycles and more adaptive control strategies in an industry where precision remains the primary barrier to higher yields.
