  • Patent number: 10670468
    Abstract: The present invention provides an infrared pixel structure and a hybrid imaging device which use comb-shaped top plates and bottom plates to form capacitors. The upper electrode has a non-fixed end such that the infrared sensitive element in the upper electrode generates thermal stress and deforms when absorbing the infrared light, which changes the capacitance of the capacitors formed by the top plates and the bottom plates to achieve infrared detection and increase the device sensitivity. Furthermore, the infrared pixel structure can be used in an infrared light and visible light hybrid imaging device to achieve visible light imaging and infrared imaging in a same silicon substrate, so as to increase the imaging quality.

  • Patent number: 9471739
    Abstract: A method is provided for designing an IC chip. The method includes receiving data from a pre-layout design process for the IC chip, routing a plurality of interconnecting wires to connect various devices of the IC chip, and extracting various circuit parameters. The method also includes simulating the IC chip using the extracted various circuit parameters to detect logic or timing error in the IC chip. The extracting the various circuit parameters includes establishing a statistical interconnect technology profile (ITP) file containing at least interconnect parasitic parameters based on correlations of interconnect layer geometric parameter variations.
