  • Patent number: 11289592
    Abstract: A structure to increase the breakdown voltage of the high electron mobility transistor is provided to solve the problem of function loss under a high voltage state. The structure includes a substrate, a conducting layer located on the substrate, a gate insulating layer and an electric-field-dispersion layer. The upper portion of the conducting layer is an electron supply layer, and the lower portion of the conducting layer is an electron tunnel layer. The gate insulating layer is laminated on the electron supply layer. The electric-field-dispersion layer is laminated on the gate insulating layer. The dielectric constant of the electric-field-dispersion layer is smaller than that of the gate insulating layer. A gate electrode is located between the electric-field-dispersion layer and the gate insulating layer. A source and a drain electrodes are respectively electrically connected to the electric-field-dispersion layer, the gate insulating layer, the electron supply layer, and the electron tunnel layer.

  • Publication number: 20220037531
    Abstract: A thin film transistor is used to solve a problem of low process efficiency of the conventional thin film transistor in preventing hydrogen diffusion. The thin film transistor includes a substrate, multilayer thin films laminated on the substrate, and at least one fluorine-containing thin film laminated in substitution for the multilayer thin films. Each of the multilayer thin films is a gate insulating layer, an active layer, a buffer layer, and a dielectric layer or a protective layer. Each of the at least one fluorine-containing thin film is a fluorine-doped insulating layer, a fluorine-doped active layer, a fluorine-doped buffer layer, and a fluorine-doped dielectric layer or a fluorine-doped protective layer. The invention further discloses a method for manufacturing the thin film transistor.

  • Patent number: 10274471
    Abstract: A gas detection module is provided with a convenient detection mechanism of the alcohol gas. The gas detection module may include a gas sensor and a detection circuit. The gas sensor includes a substrate, a gate, an insulating layer, an active layer, a source and a drain. The gate is disposed on the substrate. The insulating layer is disposed on the gate and the substrate. The active layer is disposed on the insulating layer. Each of the source and the drain is partially arranged on the active layer and extends to the insulating layer. The active layer is exposed from between the source and the drain. The detection circuit is electrically connected to the source of the gas sensor. Based on this, the deficiency of the conventional gas detection module can be overcome.
