| 20090278136 | Process for Growth of Low Dislocation Density Gan - High quality free standing GaN is obtained using a new modification of the Epitaxial Lateral Overgrowth technology in which 3D islands or features are created only by tuning the growth parameters. Smoothing these islands (2D growth) is achieved thereafter by setting growth conditions producing enhanced lateral growth. The repetition of 3D-2D growth results in multiple bending of the threading dislocations thus producing thick layers or free standing GaN with threading dislocation density below 10 | 11-12-2009 |

| 20100001289 | PROCESS FOR PRODUCING AN EPITAXIAL LAYER OF GALIUM NITRIDE - A method of manufacturing a low defect density GaN material comprising at least two steps of growing epitaxial layers of GaN with differences in growing conditions, (a.) a first step of growing an epitaxial layer GaN on an epitaxially competent layer under first growing conditions selected to induce island features formation, followed by (b.) a second step of growing an epitaxial layer of GaN under second growing conditions selected to enhance lateral growth until coalescence. | 01-07-2010 |
| 20100074826 | METHOD FOR MANUFACTURING A SINGLE CRYSTAL OF NITRIDE BY EPITAXIAL GROWTH ON A SUBSTRATE PREVENTING GROWTH ON THE EDGES OF THE SUBSTRATE - A method for manufacturing a single crystal of nitride by epitaxial growth on a substrate appropriate for the growth of the crystal. The substrate includes, deposited on the edges of its growth surface, a mask appropriate to prevent growing of the single crystal on the edges of the substrate. | 03-25-2010 |
| 20110316000 | MANUFACTURING OF LOW DEFECT DENSITY FREE-STANDING GALLIUM NITRIDE SUBSTRATES AND DEVICES FABRICATED THEREOF - The invention relates to a method for manufacturing a single crystal of nitride by epitaxial growth on a support ( | 12-29-2011 |

| 20090115793 | ENHANCED ALPHA BLENDING - A system including storage comprising a first graphical pixel and a second graphical pixel. Each of the first and second graphical pixels is associated with binary codes having red, green and blue sub-codes. The system also comprises processing logic coupled to the storage and adapted to alpha-blend the first and second graphical pixels to produce a blended pixel. The processing logic performs this alpha-blend using the binary codes having red, green and blue sub-codes in concatenated form and without operating on the sub-codes individually. The processing logic displays the blended pixel. | 05-07-2009 |

| 20110315666 | METHOD OF ABLATING A SURFACE LAYER OF A WALL, AND ASSOCIATED DEVICE - The invention relates to a method of ablating a surface layer of a wall by sweeping the said layer, comprising: a step of directional control by an optical deflector of a plurality of pulsed laser beams; a step of ablating the layer on impact zones created by the plurality of laser beams, each impact zone being defined by a centre and by a characteristic dimension; the method is characterized in that the impact zones are disjoint, the distance between each centre of the impact zones being equal to at least ten times the largest characteristic dimension of the impact zones. The invention also relates to a corresponding device. | 12-29-2011 |
