概要（Overview）

The Novellus Concept Three Speed is an advanced system designed for 300 mm wafers, boasting a proprietary hemispherical ion source and bi-polar electrostatic chuck. These innovative features ensure superior ion uniformity and precise temperature control. Even as the elements are scaled up for 300 mm wafers, the ion uniformity remains consistent due to the inherent design characteristics of the ion source. Additionally, an optimized gas delivery system enhances the overall within-wafer uniformity, further improving the system's performance.
