  • Patent number: 11145567
    Abstract: A heat-radiating substrate with a high insulation-withstand voltage and an excellent heat-radiating property is provided. The heat-radiating substrate includes: a metal base material; a metal thin layer formed over the metal base material and having a hardness higher than a hardness of the metal base material; and a ceramic layer over the metal thin layer. Alternatively, the heat-radiating substrate includes, instead of the metal thin layer, a hardened layer serving as a surface layer of the metal base material and having a hardness higher than the hardness of the metal base material. The metal thin layer and the hardened layer are able to enhance compressive stress or prevent release of the compressive stress generated in the ceramic layer by a mechanical impact applied to the ceramic layer.

  • Patent number: 11114565
    Abstract: Power consumption of a semiconductor device is reduced by sharpening the rise of a drain current when a gate voltage of a field effect transistor is less than a threshold voltage. As means therefor, in a fully-depleted MOSFET in which a thickness of a semiconductor layer serving as a channel region is 20 nm or less, a gate plug connected to a gate electrode is constituted of a first plug, a ferroelectric film, and a second plug sequentially stacked on the gate electrode. Here, an area where a contact surface between the first plug and the ferroelectric film and a contact surface between the ferroelectric film and the second plug overlap in a plan view is smaller than an area where the gate electrode and a semiconductor layer serving as an active region overlap.

  • Publication number: 20210261830
    Abstract: The present invention provides a polymer compound peeling agent usable for peeling as many types of polymer compounds as possible and capable of reducing a burden required for a peeling treatment when a polymer compound having adhered to an adhesion object is peeled. The polymer compound peeling agent for peeling a polymer compound having adhered to an adhesion object contains a photoresponsive liquid crystal material having a phase structure reversibly transitioning between an isotropic phase and a liquid crystal phase due to photoisomerization based on irradiation lights of different wavelengths. When the polymer compound is adhered to the adhesion object, the photoresponsive liquid crystal material is contained in the polymer compound with the phase structure set to the isotropic phase, and the phase structure of the photoresponsive liquid crystal material is allowed to transition from the isotropic phase to the liquid crystal phase by photoisomerization based on the light irradiation.
