Patent number: 11894333Abstract: A semiconductor package includes: a redistribution substrate including a connection via and a redistribution layer electrically connected to each other, and a redistribution pad electrically connected to the redistribution layer by the connection via, a space pattern separating at least some of the redistribution pads from each other, a dummy metal pattern at least partially surrounded by the space pattern, and a degassing opening passing through at least one of the redistribution pad and the dummy metal pattern; a connection bump electrically connected to the redistribution pad; and a semiconductor chip on the redistribution substrate and including a connection pad electrically connected to the redistribution layer, the redistribution pad including a plurality of protrusions protruding from the same plane in directions different from each other and having a corner having a rounded shape, and the dummy metal pattern includes branch patterns each extending in directions different from one another.Type: GrantFiled: August 13, 2021Date of Patent: February 6, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dahee Kim, Jeongrim Seo, Gookmi Song

Publication number: 20230411321Abstract: A package substrate may include an insulation substrate, at least one redistribution layer (RDL) and a redistribution pad. The RDL may be included in the insulation substrate. The redistribution pad may extend from the RDL. The redistribution pad may include at least one segmenting groove in a radial direction of the redistribution pad. Thus, the at least one segmenting groove in the radial direction of the redistribution pad may reduce an area of the redistribution pad. Therefore, application of physical stress to a PID disposed over the redistribution pad may be suppressed, and thus generation of cracks in the PID may be reduced. Further, spreading of the cracks toward the redistribution pad from the PID may also be suppressed, and thus reliability the semiconductor package may be improved.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Applicant: Samsung Electronics Co., Ltd.Inventors: Youngkyu LIM, Gookmi SONG, Sunguk LEE

Publication number: 20220406697Abstract: A semiconductor package includes a semiconductor chip including a connecting pad, a mold layer covering the semiconductor chip, a lower redistribution layer on the semiconductor chip and the mold layer, and a connecting terminal on the lower redistribution layer. The lower redistribution layer includes a first lower insulating layer, a first conformal redistribution pattern extending through the first lower insulating layer, a second lower insulating layer on the first lower insulating layer and the first conformal redistribution pattern, and a first filled redistribution pattern disposed on the first conformal redistribution pattern and extending through the second lower insulating layer. A side surface of the first filled redistribution pattern is spaced apart from an inner side surface of the first conformal redistribution pattern.Type: ApplicationFiled: March 15, 2022Publication date: December 22, 2022Applicant: Samsung Electronics Co., Ltd.Inventors: Dahee KIM, Gookmi SONG
