Patents by Inventor Chinwen Shih

Chinwen Shih has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7309410
    Abstract: Various traveling wave grids and related systems are disclosed that are particularly beneficial for the separation, transport, and focusing of biomolecules or other charged species. An implementation of a vertically integrated traveling wave module is described which allows for scalability to arbitrary gel dimensions through tiling. In addition, several unique traveling wave algorithms are also described which when used in conjunction with the traveling wave grids, impart selective motion to biomolecules or other charged species.

  • Publication number: 20060065909
    Abstract: Various exemplary embodiments of the systems and methods according to this invention provide for a method of producing a self-aligned thin film transistor, the transistor including a metal layer covering at least a portion of a doped layer, the doped layer covering at least a portion of a dielectric layer, a strain being created in the metal layer, the method includes etching an exposed portion of the doped layer to create a defect at an interface between the doped layer and the dielectric layer so as to initiate a delamination of the doped layer from the dielectric layer. The delamination of the doped layer from the dielectric layer is stopped when the defect propagates into an interface between the doped layer and the dielectric layer that has an adhesive energy that is greater than the strain of the metal layer.

  • Publication number: 20060063369
    Abstract: Controlled overetching is utilized to produce metal patterns having gaps that are smaller than the resolution limits of the feature patterning (e.g., photolithography) process utilized to produce the metal patterns. A first metal layer is formed and masked, and exposed regions are etched away. The etching process is allowed to continue in a controlled manner to produced a desired amount of over-etching (i.e., undercutting the mask) such that an edge of the first metal layer is offset from an edge of the mask by a predetermined gap distance. A second metal layer is then deposited such that an edge of the second metal layer is spaced from the first metal layer by the predetermined gap distance. The metal gap is used to define, for example, transistor channel lengths, thereby facilitating the production of transistors having channel lengths defined by etching process control that are smaller than the process resolution limits.
