摘要:
A method of manufacturing an optical element is disclosed which comprises the steps of providing a molding material onto a mold; giving a local temperature difference to an interface between the mold and the molding material to separate the mold and the molding material from each other in an area; and successively enlarging the area of separation made by the temperature difference to entirely separate the mold and the molding material from each other.

A semiconductor memory device includes a memory cell capacitor for storing information, wherein the memory cell capacitor includes a capacitor insulation film of a double oxide on a lower electrode. The lower electrode has a layered structure of Ir/IrO2/Ir or Ru/RuO2/Ru acting as a diffusion barrier of oxygen or Pb. Further, the use of a Pt—Ir alloy is disclosed for the lower electrode.
摘要:
The present invention relates to semiconductor techniques using high dielectric oxides, more specifically to a thin film forming method for forming a thin film which is suitable as the electrodes of the oxide high dielectrics, a capacitor device using the oxide high dielectrics and a method for fabricating the same, an a semiconductor device using the capacitor device and a method for fabricating the semiconductor device. The capacitor device comprises at least one of a pair of electrodes which is formed of a material containing titanium nitride of (200) orientation. This permits the capacitor device to have good quality even in a case that the capacitor dielectric film is formed of a high dielectric thin film grown in an oxidizing atmosphere. The capacitor device includes the electrodes of titanium nitride film, whereby the electrodes can be patterned by RIE, which much improves processing precision of the electrode patterning, and throughputs.

摘要:
A method for growing a dielectric film containing Sr on a substrate includes the steps of: dissolving a Sr compound containing Sr((CH.sub.3).sub.5 C.sub.5).sub.2 into an organic solvent or mixing Sr(thd).sub.2 and an amine compound to form a source material; vaporizing the source material to produce a gaseous source material; and decomposing the gaseous source material, obtained in the step of vaporization, in the vicinity of a surface of a substrate held in a reaction chamber, to cause a deposition of a dielectric film containing Sr upon the surface of the substrate.
摘要:
A vehicular lamp includes a lamp unit disposed inside a lamp chamber and an aiming mechanism. The lamp chamber is formed from a lamp body opening forward and a front cover attached to the front opening portion of the lamp body. The aiming mechanism is interposed between the lamp unit and the lamp body. The aiming mechanism performs an optical axis adjustment by tiltably supporting the lamp unit with respect to the lamp body. The aiming mechanism includes a rotational operation portion supported by a lamp body side fixing portion provided on the lamp body; a screw portion threadedly engaged with a lamp unit side fixing portion provided on the lamp unit; and a connection portion that joins the rotational operation portion and the screw portion. At least part of the connection portion has radial flexibility and no axial elasticity. Torque from the rotational operation portion is transmitted to the screw portion to move the lamp unit side fixing portion in the vehicle longitudinal direction.
摘要:
An element includes a first resin layer and a second resin layer disposed between a first glass lens substrate and a second glass lens substrate, a boundary surface between the first resin layer and the second resin layer having a diffraction grating shape including a plurality of inclined surfaces and wall surfaces. The second resin layer is composed of a fluororesin in which fine metal oxide particles are dispersed. Since a refractive index distribution easily occurs in this material during curing by application of ultraviolet light, by applying ultraviolet light substantially perpendicular to the inclined surfaces of the diffraction grating shape, a refractive index distribution is formed in the thickness direction perpendicularly to the inclined surfaces.
