Latest Patents

Doo-hee Cho holds a patent for a method titled "Method for forming two thin conductive films isolated electrically from each other on a fiber." This patent describes a process where a fiber is attached to grooves on a silicon substrate using photoresist as an adhesive. The method involves creating a photoresist pattern for a conductive film on the fiber's surface through photolithography. After selectively etching the fiber, a metal film is deposited, and the photoresist is removed, leaving the metal film only on the desired areas. This technique allows for the formation of a second metal film on the opposite side of the fiber, enabling the creation of advanced devices such as modulators, tunable filters, and electric field sensors.
