概要（Overview）

The RS-4000 performs at a high throughput of 1,200 DPH (defects per hour), which is about 3 times faster than the conventional model, and performs defect review at a high speed and high defect capture rate thereby improving image resolution (3 nm) and enhancing image processing. Combined with ADC (automatic defect classification) to identify killer defects, the tool produces data directly linked with yield enhancement in a short time. Furthermore, the newly added function of tilt image observation by tilting the electron beam enables the tool to generate more defect information.
