  • Patent number: 7902660
    Abstract: A substrate for a semiconductor device and a manufacturing thereof, and a semiconductor device using the same and a manufacturing method thereof are disclosed. For example, in the substrate according to the present invention, a core is eliminated, so that the substrate has a very thin thickness, as well, the length of electrically conductive patterns becomes shorter, whereby the electrical efficiency thereof is improved. Moreover, since a carrier having a stiffness of a predetermined strength is bonded on the substrate, it can prevent a warpage phenomenon during the manufacturing process of the semiconductor device. Furthermore, the carrier is removed from the substrate, whereby a solder ball fusing process or an electrical connecting process of the semiconductor die can be easily performed.

  • Publication number: 20100297755
    Abstract: Disclosed are a composition for introducing the osteogenic differentiation of human embryonic stem cells and a method for differentiating human embryonic stem cells into an osteoblastic lineage by inhibiting the mTOR signaling pathway. When cultured in the presence of an inhibitor of the mTOR signaling pathway, human embryonic stem cells are effectively induced to differentiate into an osteoblastic lineage. The osteogenic differentiation of human embryonic stem cells using the method and the composition is useful in examining the development and differentiation mechanism of osteoblasts and the cause of metabolic bone diseases, including osteoporosis. In addition, the method and the composition can be applied to the development of osteogenic differentiation techniques for generating clinically useful, terminally differentiated mature cells or progenitor cells.

  • Patent number: 7317245
    Abstract: Disclosed is a method for manufacturing a semiconductor device substrate. A substrate having no bus line and lead-in line is efficiently manufactured. In a step needing an electroplating process, conductive film is temporarily attached to circuit patterns in order to electrically connect all circuit patterns. A plating is formed in desired regions of the circuit patterns with a predetermined thickness in an electroplating method. The conductive film is completely removed while the substrate is manufactured so that the circuit patterns are electrically independent of one another, and the resulting substrate has no bus line and lead-in line.
