Patent number: 7956441Abstract: A composite structure that includes front faces of the first and second substrates that are molecularly bonded to each other. The dimensions of the second substrate outline are larger than the first substrate outline, and a peripheral side of the second substrate substantially borders the second front face and is oriented generally perpendicularly with respect thereto. The front faces are molecularly bonded such that the outline of the first front face is disposed at least partially within the outline of the second front face. A peripheral ring extending around the first front face and facing the first substrate, in which bonding between the front faces is weak or absent, has a maximum width of less than about 0.5 mm.Type: GrantFiled: September 20, 2007Date of Patent: June 7, 2011Assignee: S.O.I.Tec Silicon on Insulator TechnologiesInventor: Christophe Maleville

Patent number: 7771815Abstract: A molding glass lens and a mold thereof are disclosed. The molding glass lens consists of an upper optical surface, a lower optical surface, two outers surrounding the optical surfaces and at least three grooves arranged in the form of a circle disposed on the lower outer and/or the upper outer. The disposition of the grooves has no affecting in original size of the outers as well as assembling with other mechanical parts in les group. The mold of the lens includes an upper molding unit and a lower molding unit. Cavity of each molding unit is composed of a central part for forming an optical surface of the lens and an outer circular part for forming outer of the lens. At least three protrudent parts with the same height are disposed in the form of a circle on the outer circular of the lower molding unit and/or the upper molding unit. Thus the air in the mold cavity is easy to exhaust through the gap formed by protrudent parts and glass preform.Type: GrantFiled: August 28, 2007Date of Patent: August 10, 2010Assignee: E-Pin Optical Industry Co., LtdInventors: San-Woei Shyu, Chia-Wei Wang, Jau-Jan Deng, Wen-Huang Liu, Chien-Min Wu

Publication number: 20100159182Abstract: A method is used for producing a bulk SiC crystal having a resistivity of at least 1012 ?cm and a diameter of at least 7.62 cm. An SiC growth gas phase is generated in a crystal growth region. The bulk SiC crystal grows by deposition from the SiC growth gas phase. The SiC growth gas phase is fed from an SiC source material, which is contained in an SiC supply region inside the growing crucible. First dopants which have a flat dopant level at a distance of at most 350 meV from an SiC band edge, and second dopants which have a low-lying dopant level at a distance of at least 500 meV from the SiC band edge, are delivered in gaseous form to the crystal growth region. Bulk SiC crystals are thereby obtained, and large-area SiC substrates obtained therefrom whose resistivity is at least 1012 ?cm everywhere.Type: ApplicationFiled: December 24, 2009Publication date: June 24, 2010Applicant: SICRYSTAL AGInventors: Thomas Straubinger, Andreas Wohlfart, Martin Kölbl
