  • Patent number: 10930768
    Abstract: A method of manufacturing a field effect transistor includes forming a fin on a substrate, forming source and drain electrodes on opposite sides of the fin, forming a gate stack on a channel portion of the fin between the source and drain electrodes, forming gate spacers on extension portions of the fin on opposite sides of the gate stack, removing at least a portion of the gate spacers to expose the extension portions of the fin, and thinning the extension portions of the fin. Following the thinning of the extension portions of the fin, the channel portion of the fin has a first width and the extension portions of the fin have a second width less than the first width.

  • Publication number: 20200286097
    Abstract: The present invention relates to an electronic approval method using biometric authentication, comprising: a biometric certificate storage step in which biometric certificates issued, encrypted and hashed by a biometric authentication server are stored and activated in biometric recognition modules of a manager and approvers; an approver list registration step in which the manager logs in to an approval server and then an approver list is registered in the approval server; an approver's approval step in which for the approval of each of the approvers to the approval server, biometric information of the approvers is input into the biometric recognition modules, the biometric certificate is transmitted to the biometric authentication server accordingly, the biometric certificate is hashed to be verified whether original or not and is decrypted to be verified by the content, and then a biometric authentication result is transmitted to the approval server; an approver's approval server log-in step in which for th

  • Publication number: 20190183940
    Abstract: Methods, compositions, and kits for producing functional blood vessels, and progenitors thereof are provided. Human disorders of the vascular system are treated by reconstitution of functional vessels in vivo through co-transplantation with supporting niche stromal cells for treatment of ischemic injury in the peripheral limbs and heart. The cell populations of the invention, when engrafted into a recipient, anastomose with host vasculature and regenerate functional blood vessels.
