The KLA Surfscan SP2 is a high-sensitivity unpatterned wafer inspection system for bare wafer and blanket film quality screening. Powered by UV laser darkfield optics, it captures tiny surface defects and haze maps for substrate qualification before lithography and deposition processes.
Fitted with high-speed scanning and multi-channel detection, it generates full-wafer defect maps rapidly. It pinpoints particles, scratches and surface anomalies, supporting inline monitoring in cleanroom production.
This mature inspection platform delivers consistent results with stable laser performance. It integrates smoothly into your substrate workflow to filter defective wafers and prevent costly yield loss in downstream fabrication.
