Latest Patents

Yoshio Kimoto's latest patents include a defect classification device and an inspection device. The defect classification device aims to prevent erroneous determinations of on-film defects by reducing the sensitivity of post-inspection. This ensures that minute defects causing film swelling are not mistakenly detected. The classification process involves performing coordinate corrections based on actual-defect fine alignment and pre-inspection results using two-stage thresholds. Additionally, it prepares instruction data from the refractive index and thickness of a film formed on a wafer, comparing this data with the signal intensity ratio of a detection system. The inspection device proposed by Kimoto features an illuminating optical unit that irradiates a sample with light, a control unit for instructions, and detection units to capture transmitted light. The illuminating optical unit includes a light source and an electrooptic element that adjusts the light's polarization state based on control unit instructions.
