  • Patent number: 11996844
    Abstract: A duty cycle correction circuit includes a duty correction circuit, an information generation circuit and a duty control circuit. The duty correction circuit corrects a duty rate of an input clock signal based on a duty control code to generate an output clock signal. The information generation circuit compares a difference between operation power voltages based on an operation mode to generate voltage information. The duty control circuit receives the voltage information from the information generation circuit and generates the duty control code that includes the voltage information based on a duty rate of the output clock signal.

  • Publication number: 20240145301
    Abstract: Disclosed are a metal thin film precursor composition, a method of forming a thin film using the metal thin film precursor composition, and a semiconductor substrate fabricated using the method. The metal thin film precursor composition includes a metal thin film precursor compound and a growth regulator including a predetermined terminal group and structure. In a thin film deposition process, by using the metal thin film precursor composition, side reactions may be suppressed and thin film growth rate may be controlled appropriately. Since process by-products in a thin film are removed, even when the thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved. In addition, corrosion or deterioration may be prevented, and the crystallinity of the thin film may be improved, thereby improving the electrical properties of the thin film.

  • Publication number: 20240141061
    Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.
