| 20100104495 | METHOD FOR PRODUCING NITRIDE SEMICONDUCTOR, CRYSTAL GROWTH RATE INCREASING AGENT, SINGLE CRYSTAL NITRIDE, WAFER AND DEVICE - A method for producing a nitride semiconductor, comprising controlling temperature and pressure in a autoclave containing a seed having a hexagonal crystal structure, a nitrogen element-containing solvent, a raw material substance containing a metal element of Group 13 of the Periodic Table, and a mineralizer so as to put said solvent into a supercritical state and/or a subcritical state and thereby ammonothermally grow a nitride semiconductor crystal on the surface of said seed, wherein the crystal growth rate in the m-axis direction on said seed is 1.5 times or more the crystal growth rate in the c-axis direction on said seed. By the method, a nitride semiconductor having a large-diameter C plane or a nitride semiconductor thick in the m-axis direction can be efficiently and simply produced. | 04-29-2010 |

| 20100279503 | Method for Producing an Electrically Conductive Connection - A method for producing an electrically conductive connection between a first surface of a semiconductor substrate and a second surface of the semiconductor substrate includes producing a hole, forming an electrically conductive layer that includes tungsten, removing the electrically conductive layer from the first surface of the semiconductor substrate, filling the hole with copper and thinning the semiconductor substrate. The hole is produced from the first surface of the semiconductor substrate into the semiconductor substrate. The electrically conductive layer is removed from the first surface of the semiconductor substrate, wherein the electrically conductive layer remains at least with reduced thickness in the hole. The semiconductor substrate is thinned starting from a surface, which is an opposite surface of the first surface of the semiconductor substrate, to obtain the second surface of the semiconductor substrate with the hole being uncovered at the second surface of the semiconductor substrate. | 11-04-2010 |

| 20110297653 | METHOD AND DEVICE FOR PRODUCING NANO-STRUCTURED SURFACES - An apparatus and a method for producing nanostructured surfaces are particularly suited for producing surfaces having very low roughness over large lateral extents. The method includes the following steps: providing an article having a surface to be structured; generating short-pulse laser radiation with laser pulses whose pulse durations lie in the subnanosecond range, preferably in the range of 100 fs to 300 fs, directing the short-pulse laser radiation onto the surface to be structured on the article, such that a fluence F of each individual pulse of the short-pulse laser radiation is less than a multishot threshold fluence F | 12-08-2011 |
