RF Power Generator for Semiconductor Plasma Processes

Product Specifications

Technical details and manufacturing context for RF Power Generator

Definition

An RF Power Generator is a critical component within wafer fabrication equipment that produces radio frequency (RF) power, typically in the range of 13.56 MHz or other industrial frequencies, used to create and sustain plasma in vacuum chambers. It plays an essential role in processes such as plasma etching, chemical vapor deposition (CVD), and physical vapor deposition (PVD), where precise control of plasma density and ion energy is required for material removal or deposition on semiconductor wafers. The generator converts low-frequency AC power to high-frequency RF power using solid-state or tube-based oscillator circuits. This RF power is then transmitted through impedance matching networks to the process chamber electrodes, where it ionizes process gases to create plasma. The generator maintains stable output through feedback control systems that monitor forward and reflected power. Typical specifications include an output power range of 100–1000 W, a frequency of 13.56 MHz, frequency accuracy of ±0.01%, output power stability of ±0.5%, input voltage of 180–264 V AC, input frequency of 47–63 Hz, efficiency of ≥85%, operating temperature of 0–40°C, storage temperature of -20–70°C, humidity of ≤90% RH, IP54 rating per IEC 60529, forced air cooling, dimensions of 440×88×500 mm, and weight of ≤15 kg. These values are directory references and must be confirmed for the specific model and application. The generator is typically housed in an aluminum alloy enclosure with copper conductors, ceramic insulators, and semiconductor power devices such as IGBTs or MOSFETs. It is designed for integration into semiconductor manufacturing systems, where precise RF power delivery is essential for process repeatability and yield. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The RF Power Generator converts low-frequency AC power to high-frequency RF power using solid-state or tube-based oscillator circuits. This RF power is then transmitted through impedance matching networks to the process chamber electrodes, where it ionizes process gases to create plasma. The generator maintains stable output through feedback control systems that monitor forward and reflected power.
