Latest Patents

Hagita holds a patent for an "Inspection apparatus for circuit pattern." This apparatus utilizes an electron beam to irradiate the surface of a substrate containing multiple chips with circuit patterns. The signals produced from the irradiated substrate are detected to form an image, which is then compared with another image to identify defects in the circuit patterns. Notably, before the electron beam is directed onto the chips, it is first irradiated onto the region to control the charging conditions of the substrate being inspected. This innovative approach improves the reliability of the inspection process.
