Patent number: 11682563Abstract: Underfill materials with graded moduli for semiconductor device assemblies, and associated methods and systems are disclosed. In one embodiment, the underfill material between a semiconductor die and a package substrate includes a matrix material, first filler particles with a first size distribution, and second filler particles with a second size distribution different than the first size distribution. Centrifugal force may be applied to the underfill material to arrange the first and second filler particles such that the underfill material may form a first region having a first elastic modulus and a second region having a second elastic modulus different than the first elastic modulus. Once the underfill material is cured, portions of conductive pillars coupling the semiconductor die with the package substrate may be surrounded by the first region, and conductive pads of the package substrate may be surrounded by the second region.Type: GrantFiled: June 27, 2022Date of Patent: June 20, 2023Assignee: Micron Technology, Inc.Inventors: Jungbae Lee, Chih Hong Wang

Patent number: 7667089Abstract: Hemophilia A is one of the major inherited bleeding disorders caused by a deficiency or abnormality in coagulation factor VIII (FVIII). Hemophiliacs have been treated with whole plasma or purified FVIII concentrates. The risk of transmitting blood-borne viruses and the cost of highly purified FVIII are the major factors that restrict prophylaxis in hemophilia therapy. One of the challenges created by the biotechnology revolution is the development of methods for the economical production of highly purified proteins in large scales. The present invention provides improved mammary expression cassettes useful for the expression of genes at high levels in the milk of transgenic animals. In particular, the present invention provides recombinant signal peptide sequences derived from a-lactalbumin and aS1-casein milk genes suitable for leading protein secretion in the mammary gland.Type: GrantFiled: April 9, 2004Date of Patent: February 23, 2010Assignee: National Chung Hsing UniversityInventors: Winston T.

Patent number: 6892732Abstract: The present invention is a condom coated with lactic acid bacteria contained composition, which has not only provided the contraceptive effect and the prevention of sexually transmitted diseases transmission but also helped to establish, maintain and reestablish a non-pathogenic, natural or genetically modified intra-vaginal bacterial flora action in vagina. The lactic acid bacteria can be genetically modified and natural lactic acid bacteria such as spreads from mammal intestinal and vaginal tract. A condom is coated with composition containing powder form or other type of lactic acid bacteria such as cream, foam, micro-bead or micro-encapsulated form, which contains as its ingredients at least one species of viable lactic acid bacteria, and optionally with a lubricant. The risk of pathogenic microbial and viral infection in vagina can be decreased or prevented and the vaginal environment can be maintained in a good condition without side effect by using a condom of the present invention.Type: GrantFiled: December 23, 2002Date of Patent: May 17, 2005Assignee: Bioleader Technology Corp.Inventors: Chih-Hong Wang, Hsin-Chung Chen, Yu-Shen Cheng
