Latest Patents

Chuanfei Guo holds a patent for a "Metal Optical Grayscale Mask and Manufacturing Method Thereof." This invention features a metal optical grayscale mask that includes a layer of metal film deposited on a transparent substrate. The mask is designed with different transparency patterns formed by laser writing on the surface of the metal film. The patterns can be continuous, in the form of an array or random design. The grayscale ranges from 3.0 OD to 0.05 OD, and the thickness of the metal film varies between 5 to 100 nm. The manufacturing method involves rinsing the transparent substrate using a standard semiconductor rinse process, followed by the deposition of the metal film and the creation of transparency patterns. This grayscale mask is cost-effective, exhibits excellent antistatic properties, and achieves resolutions that surpass the optical diffraction limit. It has broad applications in micro-optical components and large-scale production of micro-electro-mechanical systems.
