Patents by Inventor WANG JIAN PING

WANG JIAN PING 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: 9472476
    Abstract: System and method for test structure on a wafer. According to an embodiment, the present invention provides a test structure for testing an integrated circuit. For example, the test structure and the integrated circuit are manufactured on a same substrate material and the testing being conducted is in a temperature-controlled environment. The test structure includes a top structure positioned above the integrated circuit, the top structure including a first metal material, which includes a first electrical terminal and a second electrical terminal. The test structure also includes a bottom structure positioned below the integrated circuit, the bottom structure including a first silicon material. A first side structure is positioned between the top structure and the bottom structure and located next to a first side of the integrated circuit. A second side structure is positioned between the top structure and the bottom structure and located next to a second side of the integrated circuit.

  • Patent number: 8415663
    Abstract: System and method for test structure on a wafer. According to an embodiment, the present invention provides a test structure for testing a chip. For example, the test structure and the chip are manufactured on a same substrate material and the testing being conducted is in a temperature-controlled environment. The test structure includes a top structure positioned above the chip. For example, the top structure can be characterized by a first surface area. The top structure includes a first metal material occupying less than 60% of the surface area. The test structure also includes a bottom structure positioned below the chip. For example, the bottom structure can be characterized by a second surface area. The second surface area is substantially equal to the first surface area. The bottom structure includes a first silicon material. The first silicon material occupies substantially all of the second surface area.
