Publication number: 20240145346Abstract: A semiconductor device includes a substrate with a conductive pattern. A semiconductor die is electrically connected to the substrate and both the semiconductor die and the substrate are at least partially covered by a package body. In some examples, through-mold vias are formed in the package body to provide electrical signal paths from an exterior surface thereof to the conductive pattern of the substrate. In some examples, through-mold vias are included in the package body to provide electrical signal paths between the semiconductor die and an exterior surface of the package body. In some examples, an interposer is electrically connected to the through-mold vias and may be covered by the package body and/or disposed in spaced relation thereto. In some examples, the interposer may not be electrically connected to the through-mold vias but may have one or more semiconductor dies of the semiconductor device electrically connected thereto.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Applicant: Amkor Technology Singapore Holding Pte.

Patent number: 11953502Abstract: The present invention relates to an epitope of a thioredoxin-1 (Trx1) antigen and a use thereof, and more particularly, to the epitope, and an antibody or an antigen-binding fragment binding thereto. The epitope region of the human Trx1 antigen confirmed in the present invention may be effectively used in the development of an improved antibody to enhance the binding affinity of an anti-Trx1 antibody. In addition, the improved antibody of the present invention is effective in improvement of performance of a breast cancer diagnosis kit due to excellent binding affinity for Trx1 and very high sensitivity and specificity, compared to a conventional anti-Trx1 antibody. Further, the accuracy and reliability of breast cancer diagnosis may significantly increase because exceptionally high sensitivity and specificity are exhibited by detecting the monoclonal antibody of the present invention, which specifically binds to Trx1, rather than detecting CA15-3, another conventional breast cancer diagnostic biomarker.Type: GrantFiled: October 12, 2018Date of Patent: April 9, 2024Assignee: E&S HEALTHCARE CO., LTD.Inventors: Kyong Hoon Suh, Dae Joong Kim, Young Kim, Mi Kyung Kim, Jong Hwan Jung, Ki Se Lee
