Capacitor Chargers for High-Power Pulsed Lasers in Semiconductor Manufacturing
USE CASE
High-power pulsed lasers used in semiconductor manufacturing require capacitor chargers with excellent reproducibility, robustness and long-term support. Technix HV supplies capacitor charging solutions for demanding laser applications, including systems used around excimer laser annealing processes.
Application context
Excimer Laser Annealing is used to locally treat silicon using pulsed UV laser energy. The laser process relies on pulsed plasma generation, and the capacitor charging stage is a critical contributor to energy stability, repeatability and system uptime.
CUSTOMER CHALLENGE
• Generate and control high-voltage charging around 30 kV.
• Provide charging current up to approximately 500 mA depending on the system architecture.
• Ensure pulse-to-pulse reproducibility in demanding laser operation.
• Maintain reliability and robustness in semiconductor manufacturing environments.
• Integrate with remote control systems and various OEM architectures.
• Support long product lifecycles and repeat supply over many years.

Why charging repeatability matters
In pulsed laser systems, variations in the charging stage can influence pulse energy and process consistency. Capacitor chargers must therefore provide repeatable charging behavior, stable control and reliable operation over long production cycles.
Engineering considerations
Relevant specifications include output voltage, charging current, average power, repetition rate, control interface, trigger and inhibit logic, safety interlocks, cooling approach, mechanical integration and serviceability.
What is the role of a capacitor charger in a pulsed laser?
The capacitor charger brings the energy storage stage to the required voltage before the laser discharge or pulse generation event.
What voltage range is typical for this application?
The referenced application requires approximately 30 kV output voltage and up to about 500 mA charging current.
Can Technix work with OEM laser manufacturers?
Yes. Technix can adapt interfaces, mechanical integration and configuration to OEM system requirements.
