    Abstract: A semiconductor device comprising a semiconductor substrate, a plurality of memory cell regions each having a plurality of memory cells disposed on the semiconductor substrate, a word line formed in a first level above the semiconductor substrate, a bit line formed in a second level above the first level, and a backing line having a lower resistance than the word line and formed in a third level above the second level. A dummy bit line is formed in the second level outside the memory cell region so as to reduce the step formed at the periphery of the memory cell region. The dummy bit line is also used to interconnect the word line and the backing line so that an electrical connection therebetween is stabilized.

    Abstract: A gallium nitride based semiconductor device is provided which includes a gallium nitride based semiconductor film with a flat c-plane surface provided on a gallium oxide wafer. A light emitting diode LED includes a gallium oxide support base 32 having a primary surface 32a of monoclinic gallium oxide, and a laminate structure 33 of Group III nitride. A semiconductor mesa of the laminate structure 33 includes a low-temperature GaN buffer layer 35, an n-type GaN layer 37, an active layer 39 of a quantum well structure, and a p-type gallium nitride based semiconductor layer 37. The p-type gallium nitride based semiconductor layer 37 includes, for example, a p-type AlGaN electron block layer and a p-type GaN contact layer. The primary surface 32a of the gallium oxide support base 32 is inclined at an angle of not less than 2 degrees and not more than 4 degrees relative to a (100) plane of monoclinic gallium oxide. Owing to this inclination, the gallium nitride based semiconductor epitaxially grown on the primary surface 32a of the gallium oxide support base has a flat surface.

    Abstract: A slurry feeding apparatus includes closed slurry bottle, piping, wet nitrogen generator, wet nitrogen supply pipe, suction and spray nozzles, temperature regulator, flow rate control valves, slurry delivery pump and controller for controlling the operation and flow rate of the slurry delivery pump. While a wafer is being polished by a CMP polisher, the controller continuously operates the pump. On the other hand, while the polisher is idling, the controller starts and stops the pump intermittently at regular intervals. No stirrer like a propeller is inserted into the slurry bottle, but the slurry is stirred up by spraying the slurry through the spray nozzle.
