Patent number: 6875639Abstract: A semiconductor chip has a quadrangle main surface, a wiring substrate, and a resin seal member for sealing the semiconductor chip, in which the resin seal member has a quadrangle main surface which confronts the main surface of the semiconductor chip. A gate cut trace portion is formed on a side face extending along a first side of the main surface of the resin seal member. A sectional area of an area between the main surface of the wiring substrate and the main surface of the resin seal member at a position outside a side face of the semiconductor chip is smaller than a sectional area of an area between the main surface of the semiconductor chip and the main surface of the resin seal member.Type: GrantFiled: March 7, 2002Date of Patent: April 5, 2005Assignees: Renesas Technology Corp., Hitachi Hokkai Semiconductor, Ltd.Inventors: Hiroshi Arai, Nobuaki Nagashima, Norihiko Kasai, Isao Seki

Patent number: 6511560Abstract: A thin, forged magnesium alloy casing is integrally constituted by a thin plate with projections on either or both surfaces, and the thin plate is as thin as about 1.5 mm or less. The thin forged casing can be produced by (a) carrying out a first forging step for roughly forging a magnesium alloy plate to form an intermediate forged product under the conditions of a preheating temperature of the magnesium alloy plate of 350-500° C., a die temperature of 350-450° C., a compression pressure of 3-30 tons/cm2, a compressing speed of 10-500 mm/sec. and a compression ratio of 75% or less; and (b) carrying out a second forging step for precisely forging the intermediate forged product under the conditions of a preheating temperature of the intermediate forged product of 300-500° C., a die temperature of 300-400° C., a compression pressure of 1-20 tons/cm2, a compressing speed of 1-200 mm/sec., and a compression ratio of 30% or less.Type: GrantFiled: April 16, 2001Date of Patent: January 28, 2003Assignees: Tokyo Seitan Inc., Sony CorporationInventors: Isao Seki, Shigeo Hama, Shigehiro Taniike, Fukashi Watanabe, Masahiko Kakizaki, Shinji Seki
