摘要:
A multilayer film forming apparatus including a film forming chamber, a substrate on which a multilayer film is formed, an optical thickness monitoring substrate which controls an optical thickness of each layer of a multilayer film, a monitor exchange system which exchanges the optical thickness monitoring substrate for each layer and a multilayer film monitoring substrate which is disposed under the optical thickness monitoring substrate to observe spectral characteristics of the multilayer film. The invention also includes a light source which irradiates light to the optical thickness monitoring substrate and to the multilayer film monitoring substrate, an optical lens which reshapes the light radiated from the light source, an optical window which lets the light into and out of the film forming chamber, a detector which detects the light quantity reflected from the optical thickness monitoring substrate and a spectral characteristics evaluation device which measures spectral characteristics of the light reflected from the multilayer film monitoring substrate. The multilayer film monitoring substrate is fixed to a holding jig to prevent itself from inclining more than ten minutes against the disposed state.

摘要:
In a heat-plasma-jet, an arc is initially generated between opposed endless ends of a pair of electrodes and is moved along the opposed endless ends of the electrodes by generating magnetic fields having the same polarity at the opposed ends of the electrodes. Thereafter, a plasma generating gas is supplied into a region in which the arc is generated.

At least one of the plurality of elastic supports includes an engagement portion having an engaging hole which is engaged with one of the plurality of the stud pins and an elastic portion in contact with the one stud pin. Mask frame vibration causes the elastic portion to rub against a respective stud pin so as to generate a frictional force for attenuating the vibration of the mask frame.

The first basic structure of the electron emission element of the present invention includes at least two electrodes disposed in a horizontal direction at a predetermined interval, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed between the electrodes. On the other hand, the second basic structure of the electron emission element of the present invention includes at least two electrodes disposed at a predetermined interval, a conductive layer disposed between the electrodes so as to be electrically connected thereto, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed on the surface of the conductive layer between the electrodes. According to these structures, an electron emission element with high stability can be obtained, in which emissions can be emitted efficiently and uniformly even in the absence of a bias voltage (electric field) from outside in an output (emission) direction of the electrons, by utilizing a transverse electric field generated between the electrodes disposed in a horizontal direction at a predetermined interval or an in-plane electric current flowing through the conductive layer disposed between the electrodes.

An electron emission element of the present invention includes a substrate, a cathode formed on the substrate, an anode opposed to the cathode, an electron emission member disposed on the cathode, and a control electrode disposed between the cathode and the anode. During operation, the electric field intensity immediately above the electron emission member is lower than that between the control electrode and the anode. Alternatively, the spatial average of an electric field intensity between the electron emission member and the control electrode is smaller than that between the control electrode and the anode.
