Latest Patents

Takamasu's latest patents include two significant inventions:

1. **Method for Reviewing a Defect and Apparatus** - This innovative method involves a light capturing step that illuminates a sample under multiple optical conditions while varying at least one of the illumination, sample, or detection conditions. It detects lights scattering from the sample, obtaining plural signals that help discriminate defects from noise based on various characteristic quantities, ultimately deriving the coordinates of the detected defects.

2. **Lighting Method and Microscopic Observation Device** - This invention features standing wave-generating planar wave illumination units that generate two light-wave planar waves. These waves produce a standing wave via interference, which is then used to illuminate the sample surface. A synchronized bias planar wave oscillates to enhance the observation of the sample, crucial for accurate microscopy.
