Zhiyun Chen 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).

  • Programmable photolithographic mask based on semiconductor nano-particle optical modulators
    Publication number: 20040150865
    Abstract: Nano-particles are provided with control circuitry to form a programmable mask. The optical characteristics of the nano-particles change to provide patterned light. Such patterned light can be used for example to expose a photoresist on a semiconductor wafer for photolithography.
