  • Patent number: 12319995
    Abstract: A vapor deposition method and a vapor deposition apparatus that, when a vapor deposition material is deposited on a substrate, make it possible to form deposition layer pattern precisely so that the deposition layer pattern is formed uniformly without a gap formed between a deposition mask and the substrate. A deposition mask is disposed with its periphery held by a frame. A substrate on which a vapor deposition layer is to be formed is mounted over the deposition mask. A vapor deposition source is disposed facing the deposition mask and evaporates a vapor deposition material. The vapor deposition is performed while the substrate is pressed vertically at a position of a center of deflection of the deposition mask and on an upper surface of the substrate until that a length of the substrate substantially becomes identical to a length of the deposition mask being bowed down and expanded.

    Abstract: A method for producing a resin film by using a resin material and accurately forming a fine pattern as a vapor deposition mask or an optical element, a method for producing an organic EL display device, a base film for forming a fine pattern and a resin film with a supporting member are provided. A liquid resin material is applied onto a supporting member to form a resin coating film (S1), and a temperature of the resin coating film is increased to a temperature at which the resin material cures, to form a baked resin film (S2). Thereafter, a base film formed by the baked resin film attached to the supporting member is processed by irradiating with lasers, to form a resin film (1b) having a desired fine pattern and the supporting member (S3). Thereafter, the baked resin film on which the fine pattern is formed is peeled from the supporting member, and the resin film having the fine pattern is obtained (S5).

  • Patent number: 10799993
    Abstract: A vapor deposition apparatus disclosed in an embodiment is configured to allow an electromagnet (3) to attract a vapor deposition mask, and comprises a control circuit (7) connected between the electromagnet (3) and a power supply circuit (6) for driving the electromagnet (3). The control circuit gradually changes a magnetic field to be generated by the electromagnet (3) when a current is applied to the electromagnet (3). As a result, the change in current to flow in an electromagnetic coil (32) of the electromagnet (3) becomes gradual and an effect of electromagnetic induction is reduced, thereby suppressing the defect of elements formed on a substrate for vapor deposition or the deterioration in property of the element.
