eVoS ME Bias Solution

Active

Direct Control of Substrate Voltage and Ion Energy Distribution

Shrinking chip dimensions and high-aspect-ratio structures demand exacting control of ion energy. With the eVoS™ platform, AE introduces a paradigm shift in bias technology. By maximizing the ability to tailor ion energy, eVoS enables precise command of etch and deposition geometries at very small dimensions. Direct control of wafer-surface voltage and ion energy distribution (IED) empowers process engineers to optimize bias performance for specific process results, ensuring sensitive feature formation. In addition, fast digital metrology and novel control algorithms enable the production of narrower IEDs compared to alternative technologies. These capabilities change what’s possible in plasma processing.
