The present invention can reduce use of gold to lower the manufacturing cost and can also improve the heat conduction efficiency of the semiconductor structure to enhance operational stability of the chips.Type: GrantFiled: October 6, 2010Date of Patent: November 15, 2011Assignee: Chipmos Technologies Inc.Inventor: Geng-Shin Shen

Patent number: 8053852Abstract: The invention is directed to enhancement of performance of a back surface incident type semiconductor device having a light receiving element and a manufacturing method thereof without increasing a manufacturing cost. A supporting body is attached to a front surface of a semiconductor substrate formed with a light receiving element and its pad electrode. Then, the supporting body is etched to form a via hole penetrating the supporting body and exposing the pad electrode. Then, a wiring connected to the pad electrode and extending onto a front surface of the supporting body through the via hole is formed. Lastly, the semiconductor substrate is separated into a plurality of semiconductor dies by dicing. The semiconductor device is mounted so that the supporting body faces a circuit board.Type: GrantFiled: July 10, 2006Date of Patent: November 8, 2011Assignee: Semiconductor Components Industries, LLCInventor: Takashi Noma

Patent number: 7999276Abstract: Disclosed are a chip-type LED package and a light emitting apparatus having the same. The chip-type LED package includes a thermally conductive substrate with lead electrodes formed thereon. An LED chip is mounted on the thermally conductive substrate, and a lower molding portion covers the LED chip. In addition, an upper molding portion having hardness higher than that of the lower molding portion covers the lower molding portion. The upper molding portion is formed by performing transfer molding using resin powder. Accordingly, since the lower molding portion can be formed of a resin having hardness smaller than that of the upper molding portion, it is possible to provide a chip-type LED package in which device failure due to thermal deformation of the molding portion can be prevented.Type: GrantFiled: May 7, 2007Date of Patent: August 16, 2011Assignee: Seoul Semiconductor Co., Ltd.Inventor: Yeo Jin Yoon
