The present invention provides a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin film layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a cathode and an anode, wherein at least one layer in the above organic thin film layer, particularly a hole transporting layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Use of the aromatic amine derivative described above materialize an organic electroluminescence device which reduces a driving voltage and makes molecules less liable to be crystallized and which enhances a yield in producing the organic EL device and has a long lifetime.

In one of the many embodiments, a method for processing a substrate is provided which includes generating a first fluid meniscus and a second fluid meniscus on a surface of the substrate where the first fluid meniscus being substantially adjacent to the second fluid meniscus. The meniscus also includes substantially separating the first fluid meniscus and the second fluid meniscus with a barrier.

Recesses in a semiconductor structure are selectively plated by providing electrical insulating layer over the semiconductor substrate and in the recesses followed by forming a conductive barrier over the insulating layer; providing a plating seed layer over the barrier layer; depositing and patterning a photoresist layer over the plating seed layer; planarizing the insulated horizontal portions by removing the horizontal portions of the seed layer between the recesses; removing the photoresist remaining in the recesses; and then electroplating the patterned seed layer with a conductive metal using the barrier layer to carry the current during the electroplating to thereby only plate on the seed layer. In an alternative process, a barrier film is deposited over recesses in an insulator. Then, relatively thick resists are lithographically defined on the field regions, on top of the barrier film over the recesses. A plating base or seedlayer is deposited, so as to be continuous on the horizontal regions of the recesses in the insulator, but discontinuous on their surround wall. The recesses are then plated using the barrier film without seedlayers at the periphery of the substrate wafers for electrical contact. After electroplating, the resist is removed by lift-off process and exposed barrier film is etched by RIE method or by CMP. Also provided is a semiconductor structure obtained by the above processes.

A novel clostridia bacterial species (Clostridium carboxidivorans, ATCC BAA-624, “P7”) is provided. P7 is capable of synthesizing, from waste gases, products which are useful as biofuel. In particular, P7 can convert CO to ethanol. Thus, this novel bacterium can transform waste gases (e.g. syngas and refinery wastes) into useful products. P7 also catalyzes the production of acetate and butanol. Further, P7 is also capable of directly fermenting lignocellulosic materials to produce ethanol and other substances.
