Providing a photo mask for KrF excimer laser lithography, which can be produced with high accuracy and low defects in a smaller number of steps. A photo mask for KrF excimer laser lithography according to the present invention is one in which a resist pattern 18 efficiently absorbing a KrF excimer laser light (wavelength: about 248 nm) is formed directly on a quartz substrate 10. The resist pattern 18 comprises: an aqueous alkali-soluble resin having a high light shielding property, which incorporates a naphthol structure having at least one hydroxyl group bound to a naphthalene nucleus; or a radiation sensitive resist having, as a main component, an aqueous alkali-soluble resin containing a derivative of the above-mentioned aqueous alkali-soluble resin as a resin matrix.
摘要:
A brazing method for brazing components is provided. The method includes the steps of: coating a bonding portion between the components with a brazing material made of Cu—Sn—Ni—P alloy; introducing reducing gas into a brazing furnace; mounting the components in the brazing furnace; and increasing temperature in the brazing furnace so that the components are brazed. The brazing method provides excellent bonding condition. Specifically, the brazing material steadily penetrates into the bonding portion between the components so that the components are brazed steadily.
摘要:
To develop a small quantity of various kinds of semiconductor devices in a short time and to realize a photomask suitable to be manufactured at a low cost. A shade pattern of a photomask is constituted by containing nanoparticles such as carbon in an organic film such as a photoresist film. A pattern is transferred to a photoresist on a semiconductor wafer by means of the reduction projection exposure using the photomask. At the time of the above exposure, it is possible to select exposure light within a range of wide wavelengths including i-line, KrF excimer laser beam, ArF excimer laser beam, or the like.

A lead-acid storage battery includes a positive electrode, a negative electrode and an electrolyte material. The foregoing negative electrode has a first grid with a first grid geometry and a first active material provided on the above first grid. The foregoing positive electrode has a second grid with a second grid geometry and a second active material provided on the above second grid. A first mesh area of the foregoing first grid is smaller than a second mesh area of the foregoing second grid, thereby achieving an excellent high rate discharge cycle life.
摘要:
A negative pattern is formed to be transparent in the far ultraviolet region including the wavelength 193 nm of an ArF excimer laser and, despite its chemical structure having high dry etching, does not swell and has excellent resolution. An acid-catalyzed reaction is utilized wherein a .gamma.-hydroxy or .delta.-hydroxy carboxylic acid structure is partially or entirely converted to a .gamma.-lactone or .delta.-lactone structure. The negative pattern is developed with an aqueous alkali solution without swelling.
摘要:
A small-sized, low cost to manufacture and inexpensive wastewater treating biological film tank by which wastewater produced in each home can be treated by each home. A treating tank 10 has therein multi continuous-pore soft ceramic 40. Waste or raw water is supplied into the tank from its top through a waste/raw water supplying pipe 21, and pushed up by the action of air bubble forced into the tank from its bottom through an air bubble generator 30, and then flows over through cylindrical guide 50 into the multi continuous-pore soft ceramic 40 wherein the water is purified by microorganisms which digest the nutrient in the waste or raw water. Surface area of the multi continuous-pore ceramic element 40 is about 25 times larger than that of a conventional plastic element.
摘要:
The fuel supply to an internal combustion engine is controlled by fuel injection signals that depend on the intake manifold pneumatic pressure PM and the engine running speed NE. The basic pulse width TP of the fuel injection signal is calculated from the equation TP=(TPBSE+TPNE)TPKNE, where TPBSE is taken from a one-dimensional function table PM-TPBSE, TPNE is taken from a one-dimensional function table NE-TPNE, and TPKNE is taken from a one-dimensional function table NE-TPKNE.
