Publication number: 20210305190Abstract: Semiconductor packages may include a semiconductor chip on a substrate and an under-fill layer between the semiconductor chip and the substrate. The semiconductor chip may include a semiconductor substrate including first and second regions, and an interlayer dielectric layer that may cover the semiconductor substrate and may include connection lines. First conductive pads may be on the first region and may be electrically connected to some of the connection lines. Second conductive pads may be on the second region and may be electrically isolated from all of the connection lines. The semiconductor chip may also include a passivation layer that may cover the interlayer dielectric layer and may include holes that may expose the first and second conductive pads, respectively. On the second region, the under-fill layer may include a portion that may be in one of the first holes and contact one of the second conductive pads.Type: ApplicationFiled: January 12, 2021Publication date: September 30, 2021Inventors: Jimin Choi, Jung-Hoon Han, Yeonjin Lee, Jong-Min Lee, Jihoon Chang

Patent number: 7722887Abstract: The present invention relates to detoxified and immunologically active proteins (“mutant LTs”) having mutated amino acid sequences of heat-labile enterotoxin of E. coli, DNA sequences encoding the mutant LTs, recombinant expression vectors comprising the DNAs, recombinant microorganisms transformed with the recombinant expression vectors, process for preparing the mutant LTs and pharmaceutical application of the said protein as immunogenic antigens for vaccination and as adjuvants for anti-body production. In contrast to wild-type LT, the mutant LTs did not induce any toxic activities. The mutant LTs elicited high and comparable levels of anti-LT antibodies when delivered either intragastrically or intranasally, inducing systemic and local responses in serum and fecal extracts. Thus, they might be useful for the development of a novel diarrheal vaccine in humans and animals.Type: GrantFiled: September 15, 1999Date of Patent: May 25, 2010Assignee: Mogam Biotechnology Research InstituteInventors: Eun Jeong Park, Jang Seong Kim, Jihoon Chang, Jungsun Yum, Soo-il Chung

Patent number: 7118905Abstract: The present invention provides a novel angiogenesis inhibitor, LK68 whose amino acid sequence is identical with the human apolipoprotein (a) kringle domains IV36, IV37 and V38, a cDNA sequence encoding the LK68, a recombinant expression vector comprising the cDNA, a recombinant microorganism transformed with the recombinant expression vector and a novel use of the LK68 as an anticancer agent and a method for treating angiogenesis-mediated disease. LK68, LK6, LK7 and LK8 exhibit inhibitory activities on the cultured endothelial cell proliferation as well as on the endothelial cell migration. LK68 and its single kringles also inhibit the normal development of capillaries in the chick embryo chorioallantoic membrane (CAM). It was also showed that systemic administration of LK68 causes the inhibition of primary tumor growth, which is correlated with a suppression of tumor-induced angiogenesis.Type: GrantFiled: May 19, 2004Date of Patent: October 10, 2006Assignee: Mogam Biotechnology Research InstituteInventors: Jihoon Chang, Jang Seong Kim, Eun Jeong Park, Jung-sun Yum, Soo-il Chung
