As a shape on a cross-section vertical to a longitudinal direction (L) of the hot cathode fluorescent lamp (20a (20b)), a light source rear side reflecting plane (62) of a reflector (60) includes a mound portion (623). The mound portion (623) is defined by two recessed inclining planes and protrudes toward a hot cathode fluorescent lamp (20a (20b)).

In a microwave plasma processing apparatus, the reflection of microwave by the joint unit between the microwave supplying waveguide and the microwave antenna is reduced by providing a taper surface or a member having a medium permittivity between the microwave supplying waveguide and the microwave antenna so as to moderate an impedance change. Accordingly, the efficiency of power supplying is improved, and reduced discharge ensures stable formation of plasma.

In a substrate processing apparatus, a control electrode (131) separates a process space (11C) including a substrate to be processed and a plasma formation space (11B) not including the substrate. The control electrode includes a conductive member formed in a processing vessel and having a plurality of apertures (131a) for passing plasma. A surface of the control electrode is covered by an aluminum oxide or a conductive nitride. In the substrate processing apparatus, a gas containing He and N2 is supplied into the processing vessel. In the plasma formation space, there is formed plasma under a condition in which atomic state nitrogen N* are excited. The atomic state nitrogen N* are used to nitride a surface of the substrate.

A liquid crystal display including a liquid crystal panel and an organic EL device, which functions as a backlight. The organic EL device includes a Peltier element, which functions as a substrate, and an organic EL element formed on the Peltier element. The organic EL element includes an organic EL layer and first and second electrodes, which sandwich the organic EL layer. The first electrode is shared with a metal layer, which is a heat absorbing electrode of the Peltier element. The second electrode is formed from ITO, which transmits visible light. Light emitted from the organic EL element exits from the second electrode. As a result, the organic EL device is thin and has a superior cooling effect.

摘要:
In a semiconductor device formed on a silicon surface which has a substantial (110) crystal plane orientation, the silicon surface is flattened so that an arithmetical mean deviation of surface Ra is not greater than 0.15 nm, preferably, 0.09 nm, which enables to manufacture an n-MOS transistor of a high mobility. Such a flattened silicon surface is obtained by repeating a deposition process of a self-sacrifice oxide film in an oxygen radical atmosphere and a removing process of the self-sacrifice oxide film, by cleaning the silicon surface in deaerated H2O or a low OH density atmosphere, or by strongly terminating the silicon surface by hydrogen or heavy hydrogen. The deposition process of the self-sacrifice oxide film may be carried out by isotropic oxidation.

A microwave plasma processing apparatus is disclosed that enables fast and easy plasma ignition at the pressure for plasma processing In the microwave plasma processing apparatus, a plasma ignition facilitating unit is provided to facilitate plasma ignition induced by a microwave. The plasma ignition facilitating unit includes a deuterium lamp that emits vacuum ultraviolet rays, and a transmission window that allows the vacuum ultraviolet rays to penetrate and irradiate a plasma excitation space. The transmission window is a convex lens, and focuses the vacuum ultraviolet rays to enhance ionization of the plasma excitation gas. With such a configuration, it is possible to induce plasma ignition easily and quickly.
