Latest Patents

One of Ahn's latest inventions is a thin film characteristic measuring apparatus. This apparatus is designed to measure the thickness or width of a thin film on an object to be examined. It comprises a light source, a first reflecting mirror, a first actuator, and a lens assembly. The lens assembly is engineered to ensure that the angle formed by the optical axis and a chief ray of the transmitted rays is less than or equal to that of the incident rays. The light source may include superluminescent diodes (SLD). This innovative apparatus allows for accurate measurement of a relatively large area while enabling various control over the position to be measured.

Another notable patent is a lithography apparatus and pattern forming method that utilizes a liquid crystal panel for a photo mask function. This apparatus includes a stage, a first light source unit, an optical system, and an LC panel. The LC panel receives signals from an image editing means and displays the edited image to perform a photo mask function. The second light source unit provides the necessary light for exposure on the test material using the image displayed on the LC panel.
