Latest Patents

Jan Ingwersen holds a patent for a method titled "Gray scale mask and depth pattern transfer technique using inorganic." This patent describes a method of producing a high-resolution expanded analog gray scale mask. The technique utilizes inorganic chalcogenide glass, such as selenium germanium, coated with a thin layer of silver. This method allows for accurate control of the size, uniformity, and variance of the pixels. The unique structure of the selenium germanium glass, composed of column structures arranged perpendicularly to the substrate, provides an edge precision of 100 .ANG.. This innovation prevents undercutting during the etching process, enabling pixels to be placed closely together. Consequently, this technology can be used to impress information as a modulated thickness on a selenium germanium photoresist layer on an inorganic substrate.
