  • Patent number: 8732631
    Abstract: Systems, apparatus and methods for handling verification violations are disclosed. In one aspect, a method stores a list of fix information in addition to geometric shapes for each layer during verification, such as design rule checking For each primitive operation step performed during verification, two tasks are performed. First, if the primitive operation is a dimensional checking operation (i.e., width, spacing or enclosure), then for each violation, the first task creates fix information containing violation edge pairs and adds the created fix information to the fix information list on the output layer. Second, for all operations and after the output shapes on the output layer are generated, a second task passes the fix information on input layers which overlap any output shape of the output layer to the output layer's fix information list. Finally, fix guides for the final violation results are generated and drawn based on the final fix information list.

  • Publication number: 20050094707
    Abstract: An electrical thermometer comprises a metallic tip and a main body equipped with a probe portion. The front end of the probe portion is fitted into the opening of the metallic tip, which resembles a shell with a blunt end. The probe portion is formed on the main body. A thermal sensor, which is immersed and fixed in thermally conductive glue, is positioned inside the front inner end of the metallic tip. The remaining space within the metallic tip is filled up with a good thermally insulator. The metallic tip can be rapidly heated up with body temperature whenever touched, and the heat will be transferred to the thermal sensor via the thermally conductive glue. In additional, the thermally insulator can stop succeeding heat transfer.
