  • Patent number: 11024726
    Abstract: The present disclosure provides a skyrmion diode using skyrmions as information carriers. The skyrmion diode includes a magnetic body and a conductive body. The magnetic body has a skyrmion which is used as information carrier. The conductive body is disposed on or under the magnetic body. The conductive body includes a Dzyaloshinskii-Moriya interaction (DMI) region and a defect region. The DMI region is provided to induce DMI in a region of the magnetic body corresponding to the DMI region by the spin-orbit coupling of the conductive body and magnetic moments of the magnetic body. The defect region is provided to prevent the DMI from being induced in a region of the magnetic body corresponding to the defect region.

  • Patent number: 11004976
    Abstract: A semiconductor device has a silicide source/drain region is fabricated by growing silicon on an epitaxial region including silicon and either germanium or carbon. In the method, a gate electrode is formed on a semiconductor substrate with a gate insulating layer interposed therebetween. An epitaxial layer is formed in the semiconductor substrate at both sides of the gate electrodes. A silicon layer is formed to cap the epitaxial layer. The silicon layer and a metal material are reacted to form a silicide layer. In a PMOS, the epitaxial layer has a top surface and inclined side surfaces that are exposed above the upper surface of the active region. The silicon layer is grown on the epitaxial layer in such a way as to cap the top and inclined surfaces.
