The shielding frame is singulated through the bodies or through the plate and penetrable material to separate the die. TIM is formed over the die adjacent to the plate of the shielding frame. A heat sink is mounted over the plate of the shielding frame.Type: GrantFiled: January 13, 2012Date of Patent: July 23, 2013Assignee: STATS ChipPAC, Ltd.Inventors: Reza A. Pagaila, Yaojian Lin

Patent number: 8481393Abstract: A semiconductor substrate is irradiated with accelerated hydrogen ions, thereby forming a damaged region including a large amount of hydrogen. After a single crystal semiconductor substrate and a supporting substrate are bonded to each other, the semiconductor substrate is heated, so that the single crystal semiconductor substrate is separated in the damaged region. A single crystal semiconductor layer which is separated from the single crystal semiconductor substrate is irradiated with a laser beam. The single crystal semiconductor layer is melted by laser beam irradiation, whereby the single crystal semiconductor layer is recrystallized to recover its crystallinity and to planarized a surface of the single crystal semiconductor layer. After the laser beam irradiation, the single crystal semiconductor layer is heated at a temperature at which the single crystal semiconductor layer is not melted, so that the lifetime of the single crystal semiconductor layer is improved.Type: GrantFiled: July 27, 2010Date of Patent: July 9, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Masaki Koyama, Fumito Isaka, Akihisa Shimomura, Junpei Momo

Patent number: 8455365Abstract: A device and method for device fabrication includes forming a buried gate electrode in a dielectric substrate and patterning a stack that includes a high dielectric constant layer, a carbon-based semi-conductive layer and a protection layer over the buried gate electrode. An isolation dielectric layer formed over the stack is opened to define recesses in regions adjacent to the stack. The recesses are etched to form cavities and remove a portion of the high dielectric constant layer to expose the carbon-based semi-conductive layer on opposite sides of the buried gate electrode. A conductive material is deposited in the cavities to form self-aligned source and drain regions.Type: GrantFiled: May 19, 2011Date of Patent: June 4, 2013Inventors: Dechao Guo, Shu-Jen Han, Keith Kwong Hon Wong, Jun Yuan
