  • Publication number: 20190198403
    Abstract: A method for inline inspection during semiconductor wafer fabrication is provided. The method includes forming a plurality of test structures on a semiconductor wafer along two opposite directions. An offset distance between a sample feature and a target feature of each of the test structures increases gradually along the two opposite directions. The method further includes producing an image of the test structures. The method also includes performing image analysis of the image to recognize a position with an extreme of a gray level. In addition, the method includes calculating an overlay error according to the recognized position.

  • Patent number: 9667948
    Abstract: A method and system for providing a three-dimensional (3D) display. A variable length z-axis is added to each of plural (x,y) cells in a two-dimensional (2D) Cartesian plane creating plural three-dimensional (3D) cells each with a x, y and z axis. The z-axis includes a variable length light source for each of the plural x-y cells. The z-axis also includes a space vector including time and space information. A 3rd dimension is created by changing a length of the light source. A 2D image cell at (x, y) is moved along the 3D z-axis (x, y, z?) with viewing angle (?) to create a converted 3D image. An original 2D image adding z-axis with a space vector can be viewed as a 3D image on any network device (e.g., smart phone, tablet, wearable device, TV, etc.) without additional devices such as 3D glasses, 3D set-top boxes, etc.

  • Patent number: 9100182
    Abstract: A digital communications test system and method for testing a plurality of devices under test (DUTs) in which multiple sets of a single vector signal analyzer (VSA) and single vector signal generator (VSG) can be used together to perform error vector magnitude (EVM) measurements for one or more DUTs in parallel, including one or more of composite, switched and multiple input multiple output (MIMO) EVM measurements. This allows N pairs of a VSA and VSG to test N DUTs with N×N MIMO in substantially the sane time as a single VSA and VSG pair can test a single DUT, thereby allowing a substantial increase in testing throughput as compared to that possible with only a single VSA and VSG set.

  • Patent number: 8305935
    Abstract: A method and system for dynamic information exchange on mesh network devices. The dynamic information exchange includes allowing a mesh network device to communicate location information with a network device at pre-determined physical location and invite social contacts of the mesh network device to come to the pre-determined physical location. The network device sends various types of electronic messages (e.g., text message, e-mail, etc.) on a mesh network and/or a non-mesh communications network (e.g., the Internet, etc.) and to social networking sites. The dynamic information exchange also includes exchanging plural activity messages including a security identification authorization message for allowing access to a secure area, a building management message for automatically and dynamically managing heating, ventilation and/or air conditioning (HVAC) and/or an emergency location message for providing three-dimensional (3D) emergency location information.
