  • Publication number: 20120103254
    Abstract: Provided is thin-film formation system including: a first conveying mechanism to convey a substrate and a deposition mask to a substrate carry-in position; a second conveying mechanism to convey the substrate and the deposition mask aligned by an alignment mechanism placed at the substrate carry-in position; a film formation mechanism to laminate a layer of organic material on the substrate in a film formation interval of the second conveying mechanism; and a third conveying mechanism to convey the substrate and the deposition mask which have passed the film formation interval from a carry-out position, in which at least one of the first conveying mechanism and the third conveying mechanism is placed parallel to the second conveying mechanism.

  • Publication number: 20100078113
    Abstract: A method for depositing a film includes preparing a deposition material that is purified by sublimation, solidifying the purified deposition material in an environment having a reduced water content, conveying the solidified deposition material into a film deposition chamber through an environment having a reduced water content, and depositing a film of the solidified deposition material onto a substrate in the film deposition chamber.

  • Patent number: 7582185
    Abstract: A plasma-processing apparatus having a high frequency power application electrode in which plasma is generated by supplying VHF power to the high frequency power application electrode. The plasma-processing apparatus has an impedance-matching equipment comprising a capacitive element and an inductive element, which are mutually connected in series. The apparatus is arranged so that the capacitive element and the inductive element of the impedance-matching equipment are symmetrical with respect to the center of the high frequency power application electrode.

  • Publication number: 20090061084
    Abstract: In a vapor deposition method of forming a film of an organic compound on a substrate, a material containing portion filled with a vapor deposition material is heated, to thereby evaporate or sublimate the vapor deposition material and discharge the vapor deposition material to a film formation space of a vacuum chamber through a plurality of pipings connected to the material containing portion, and a piping having a smaller conductance among the pipings having different conductances is provided with a flow rate adjusting mechanism for controlling an amount of the vapor deposition material released into the vacuum chamber, whereby a film formation speed can be adjusted finely.

  • Patent number: 6881684
    Abstract: A plate high-frequency electrode for supplying a high-frequency power of the VHF band and a grounding electrode are disposed in opposition to each other at an interval of less than 8 mm in a vacuum vessel; at least a silane-based gas and nitrogen gas as source gases are introduced into a reaction space of the vacuum vessel, and a silicon nitride deposited film is formed with the pressure of the reaction space being kept at 40 to 133. Thereby, a silicon nitride film with good quality can be obtained.
