    摘要: An electrostatic chuck device provided with a dielectric plate with a surface embossed to give it a plurality of projections, an electrode, and an external power source, wherein substrate supporting surfaces of the plurality of projections are covered by conductor wiring and the conductor wiring electrically connects the substrate supporting surfaces of the plurality of projections. At the time of substrate processing, when the embossed projections contact the back of the substrate, the back of the substrate and the conductor wiring is made the same in potential due to the migration of the charges, the generation of force between the back of the substrate and the conductor wiring being in contact with the same is prevented, and a rubbing state between the two is prevented. Due to this, the electrostatic chuck device reduces the generation of particles, easily and stably removes and conveys substrates, and realizes a high yield and system operating rate.

    摘要: A piezoelectric ceramic composition comprises a composite perovskite type oxide of Pb(Ni1/3Nb2/3)O3 and simple perovskite type oxides of PbTiO3 and PbZrO3 as main components. The composition range of the main components exists in an area surrounded by lines for connecting respective composition points, i.e., a point A (X=40, Y=37, Z=23), a point B (X=36, Y=37, Z=27), a point C (X=33, Y=40, Z=27), and a point D (X=37, Y=40, Z=23) in a triangular coordinate system defined by apexes of Pb(Ni1/3Nb2/3)O3, PbTiO3, and PbZrO3, provided that Pb(Ni1/3Nb2/3)O3 amounts to X molar %, PbTiO3 amounts to Y molar %, and PbZrO3 amounts to Z molar %. The composition makes it possible to realize a large strain amount while suppressing the relative dielectric constant to be low. The composition is preferably usable for an piezoelectric actuator of an ink-jet head.

    摘要: A deposition apparatus has a reactor 11 which is furnished with a reaction gas delivery part 13 and a substrate holder 12 in which reaction gas is delivered from the reaction gas delivery part to a substrate 23 on the substrate holder, and a thin film is deposited on the substrate by means of a chemical reaction which results from supplying HF power to the reaction gas delivery part. Plasma is generated and excites the reaction gas. The gas delivery parts 27, 29, 30, 31 produce a flow of purge gas in the dead space surrounding the reaction gas deliver part. Reaction gas which is liable to be retained in the dead space is driven out by the flow of this gas, and circulation and retention of reaction gas are prevented.

    摘要: A W film having good surface morphology and high reflectance is formed while avoiding any degradation of the characteristics such as specific resistivity. The method for forming a thin film is carried out by depositing a W film on a heated substrate using CVD. The raw material gas is WF.sub.6, and the reducing gases are SiH.sub.4 and H.sub.2. In the first stage of the film formation, the reaction between WF.sub.6 and SiH.sub.4 forms nuclei on the surface of the substrate. In the second stage, following the first stage, the reaction between WF.sub.6 and H.sub.2 forms the W film. The second stage is controlled to form crystal grains of a predetermined size. The first stage and the second stage are alternately repeated as many times as necessary.
