摘要:
The negative-working resist composition which comprises a (meth)acrylate copolymer comprising (a) a vinyl monomer unit which contains in a side chain thereof at least one carbon--carbon double bond which does not concern itself with any polymerization reaction, but is able to be crosslinked with a crosslinking agent, (b) an acrylamide or methacrylamide monomer unit, (c) an acrylic acid or methacrylic acid monomer unit and (d) an acrylic acid or methacrylic acid adamantyl monomer unit as well as a crosslinking agent capable of being decomposed upon exposure to a patterning radiation and then causing crosslinking of said copolymer upon heating. The resist composition is particularly suitable for excimer laser lithography using an aqueous basic solution as a developer, and the formed resist patterns can exhibit a high sensitivity and excellent dry etch resistance without swelling.

A piezoelectric fluid pump includes a stationary pump base and a plurality of piezoelectric elements arranged in parallel on the stationary pump base, each of the piezoelectric elements having, in a polarizing direction thereof or in a direction perpendicular to the polarizing direction, a first end fixed to the stationary pump base and a free, second end. The free, second ends of respective pairs of adjacent the piezoelectric elements are connected to each other, for respective units of the fluid pump. Between the pair of piezoelectric elements and between the stationary pump base and the connecting means, pressure chambers are defined. There are gaps are between walls of the piezoelectric elements and walls of piezoelectric elements of adjacent units.

An electrode for a discharge lamp such as high pressure metal vapor lamps and fluorescent lamps is improved by using an electron emission material comprising lanthanum oxide and yttrium oxide. The electron emission material can be a combination of lanthanum oxide and yttrium oxide with barium.strontium.calcium tungstate or an alkaline earth metal oxide including at least barium oxide.When the electrode is used in a high pressure metal vapor discharge lamp, luminous flux maintenance percent in an initial lightening period is highly improved without forming a black deposition at an end of an arc tube.When the electrode is used in a fluorescent lamp, a formation of a black deposition is prevented and a starting voltage is lowered.

In the existent method for manufacturing a solar cell, manufacture of a solar cell having a quantum well having a crystalline well layer and capable of controlling the thickness of the well layer was difficult. A quantum well having an amorphous well layer, comprising a barrier layer and an amorphous well layer is formed and then the quantum well having the amorphous well layer is annealed thereby crystallizing the amorphous well layer to form a quantum well having a crystalline well layer. By applying energy density applied to the amorphous well layer at an energy density of 1.26 J/mm2 or more and 28.8 J/mm2 or less, the crystalline well layer can be formed and the lamination structure of the quantum well can be maintained simultaneously.
