  • Publication number: 20120044415
    Abstract: An image pickup module includes a cover member, an image pickup device chip including photodiodes, a fixing member which is arranged around the image pickup device chip and which connects the cover member and the image pickup device chip together, a rewiring substrate arranged on the side opposite to the cover member of the image pickup device chip, connection members for connecting the image pickup device chip with the rewiring substrate, and a space surrounded by the cover member, the image pickup device chip, and the fixing member. The image pickup device chip includes a semiconductor substrate. The semiconductor substrate includes through-hole electrodes penetrating the substrate. When an area corresponding to the fixing member in the orthogonal projection of the image pickup module with respect to the cover module is defined as a fixed area, the through-hole electrodes and the connection members are arranged in the fixed area.

  • Publication number: 20040118489
    Abstract: The present invention provides a process of producing a family of hot rolled dual phase steel sheets having excellent formability and stretch flangeability, with yield strengths of from about 500 MPa to about 900 MPa from a single steel chemistry consisting of, by weight percent, 0.02-0.15% of C, 0.3-2.5% of Mn, 0.1-2.0% of Cr, 0.01-0.2% Al, 0.001-0.01% Ca, not more than 0.1% P, not more than 0.03% S, not more than 0.2% Ti, not more than 0.2% V, not more than 0.2% Nb, not more than 0.5% Mo, not more than 0.5% Cu, not more than 0.5% Ni, the balance being Fe and unavoidable impurities. A slab or ingot of this composition is reheated to a temperature of between 1050° C. and 1350° C. and held at this temperature for at least 10 minutes, then hot rolled, completing the hot rolling at between 800° C. and 1000° C. The sheet is cooled, immediately after completion of hot rolling, at a rate of not lower than 10 C/sec.
