Latest Patents

Wei Zhou's latest patents include innovative technologies that improve substrate inspection. One of his notable inventions is an inspection system that utilizes calibration and imaging. This system features an optical assembly that establishes a path between a light source and a detector. The optical assembly is designed to have a considerable amount of longitudinal chromatic aberration, allowing light at different wavelengths to focus on distinct regions of a substrate simultaneously. This dual functionality enables the system to operate in both calibration and imaging modes, enhancing its versatility.

Another significant patent is a scratch detection method and apparatus. This invention provides a method for identifying discontinuities on the surface of a substrate. By positioning the object plane of an imaging system at a focal position associated with a discontinuity, the system captures images where the discontinuity contrasts sharply with the substrate surface. This approach makes it easier to discern discontinuities and allows for the extraction of their characteristics.
