  • Publication number: 20220020671
    Abstract: The present invention minimizes parasitic inductance at the time of packaging a semiconductor that requires high efficiency and high-speed switching driving. In implementing a semiconductor package composed of one or more switching devices and one or more diode devices, the present invention provides a flip-stack structure in which a switching device is mounted on an insulating substrate or a metal frame, a flat metal is bonded onto the switching device, and a diode device is flipped and stacked on the flat metal, and accordingly, the flat metal with a large area is used for connection between the devices and between the devices and the insulating substrate, thereby minimizing parasitic inductance generated at a time of semiconductor packaging and automating the entire process of the semiconductor packaging.

  • Patent number: 11115393
    Abstract: One or more example embodiments include user terminals, methods, and/or computer-readable recording mediums storing computer programs, in which information encrypted or decrypted not to be decoded by a message server that controls transmission and reception of messages between one or more user terminals is not shared with the message server. One or more example embodiments include user terminals, methods, and/or computer-readable recording mediums storing computer programs, which encrypt a first message by using an encryption key, transmit the first message from a first user terminal to a second user terminal, and decrypt a second message received from the second user terminal by using the encryption key.
