  • Publication number: 20190057960
    Abstract: Disclosed is a semiconductor device having an e1ectrostatic discharge protection structure. The e1ectrostatic discharge protection structure is a diode connected between a gate e1ectrode and a source e1ectrode of the semiconductor device. The diode comprises a diode body and two connection portions connected to two ends of the diode body and respectively used for electrically connecting to the gate e1ectrode and the source e1ectrode. Lower parts of the two connection portions are respective1y provided with a trench. An insulation 1ayer is provided on an inner surface of the trench and the surface of a substrate between trenches. The diode body is provided on the insu1ation 1ayer on the surface of the substrate. The connection portions respectively extend downwards into respective trenches from one end of the diode body. A dielectric layer is provided on the diode, and a meta1 conductor 1ayer is provided on the dielectric layer.

  • Patent number: 10131995
    Abstract: This disclosure relates to a preparation method of a low-pH controlled-release intelligent corrosion inhibitor. The low-pH controlled-release intelligent corrosion inhibitor comprises a hydrogel with low pH responsiveness and a corrosion inhibiting substance having the capacity of corrosion inhibition. That is, a corrosion inhibiting substance is wrapped in a low-pH sensitive hydrogel. The swelling degree of the pH sensitive hydrogel may be changed according to the amounts of monomers and crosslinking agents so as to control the releasing speed of the corrosion inhibiting substance. By the soaking experiment and the measurements of electrochemical polarization curves and alternating impedance spectra, the sensitive and long-lasting features of the low-pH controlled-release intelligent corrosion inhibitor are indicated.
