Advanced Energy Industries has developed an impedance matching network with new algorithms and direct generator communication for more accurate control of plasma systems for making sub-2nm chips.

The NavX uses RF synchronisation for impedance matching to accelerate the response time and minimize reflected power for precise control of plasma characteristics in complex semiconductor processes.

Next-generation semiconductor etch processes require unprecedented levels of plasma control during rapid pulsing, frequent transitions, and longer recipes that are needed to fabricate smaller, faster and more efficient chips with more complex 3D structures such as RibbonFETs and CFETs.

Advanced Energy’s NavX matching network is specifically designed with direct match-generator communication and ultra-fast tuning leveraging AE hardware and proprietary algorithms. This enables RF-synchronized impedance matching during multilevel pulse states for precise control of plasma characteristics. Paired with the eVerest generator, NavX completes AE’s latest RF delivery system (RFDS) for improved control of plasma characteristics.

“Building on over 20 years of experience in developing advanced RF delivery systems for plasma processes, the NavX matching network redefines tuning speed, sophistication and RF synchronization for exacting plasma control across the most complex pulsing profiles,” said Juergen Braun, Advanced Energy’s senior vice president of plasma power products.

“The platform’s groundbreaking selectable tuning algorithm, which enables impedance matching to multiple RF pulse states, instantly reduces reflected power in processes with shorter RF-on times.”

NavX directly synchronizes with the eVerest RF generator and incorporates proprietary Advanced Selectable Tuning and Velocity Tuning algorithms that optimize response speeds for pulse sequences. The system’s +/- 10% frequency span enables faster tuning and access to a wider impedance range. Intermodulation distortion (IMD) immunity maintains tuning accuracy in multi-frequency applications, and scalable pulse states provide a path to new energy regimes.

The NavX matching network is fully compatible with the PowerInsight by Advanced Energy IoT platform, which provides rapid access to high-resolution, actionable data that supports process optimization.
