Chang B. Jeong 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).

  • Semiconductor device having a thin-film resistor
    Patent number: 5414404
    Abstract: A manufacturing method for a thin film resistor is disclosed. An insulating layer is formed on a substrate having a contact region. The insulating layer above the contact region is removed by etching to expose the contact region. A metal layer and an interlayer are then formed in sequence on the surface of the structure. The metal layer and the interlayer above the region where the resistor will be formed is next removed, and then a resistor layer is formed on the surface of the structure. The thin film resistor is completed by etching away the resistor layer except for the predetermined region where the resistor is to be formed.
    Type: Grant
