Title: Shih-Fu Lee: Innovator in Lithography and Optical Recording
Introduction
Shih-Fu Lee is a prominent inventor based in Fremont, CA. He has made significant contributions to the fields of lithography and optical recording, holding a total of 12 patents. His innovative work has paved the way for advancements in technology and manufacturing processes.
Latest Patents
One of Shih-Fu Lee's latest patents is a method for imprint lithography. This method involves imprinting a first pattern with a first template on a substrate of a lithographic template. A second pattern is then imprinted with a second template on the same substrate, resulting in a third pattern formed by the overlap of the first and second patterns. This third pattern is lithographically created on a second substrate using the lithographic template. In one embodiment, the first pattern consists of a concentric line pattern formed by thin film deposition, while the second pattern is a radial line pattern. Additionally, the line frequency of both patterns may be increased.
Another notable patent is related to a multilevel data structure. This method focuses on writable optical recording of a medium to create multilevel oriented nano-structures. It includes providing a disc-shaped, writable recording medium with a planar surface and encoding data by forming multilevel nano-structured pits in the surface. This is achieved by scanning with a focused spot of optical energy to create at least one data track while rotating the disc about a central axis.
