Ensures that process conditions remain consistently good
The special power and control design ensures sound voltage stability, which is crucial for coating quality and a stable process. Designed using DSP technology and equipped with FPGA signal processing, the TruPlasma Bias Series 4000 has modern arc management, which offers a unique degree of accuracy and repetition accuracy. The impressive values of both parameters ensure optimal process stabilization.
Simplified system handling with a single device for multiple processes
The TruPlasma Bias Series 4000 has two separate voltage modes: a high-voltage mode with up to 1200 volts and a low-voltage mode with up to 300 volts. In particular, the modes support optical and metallic coating applications that are used in semiconductor technology or hard material coating, for example. They are also well-suited for applications with comparable voltage and current requirements.
Seamless processes result in optimal coating quality
The generators in the TruPlasma Bias Series 4000 have completely digital arc management with very low arc energy and CompensateLine, thus enabling high coating quality and deposit rates. This means there is less droplet deposition and substrate damage, improving both the process and the product.
The user-friendly, multilingual PVD Power software offers you numerous operation, configuration, and diagnosis options for optimizing process quality and effective error correction: display actual values for all relevant process parameters as well as warnings and alarms, specification of target values by the operator, as well as recording and visualization of important operating parameters with high temporal resolution (oscilloscope function).
