Abstract: The present invention provides a method for producing an organic EL device comprising a step of eliminating a partition wall 3, which has become unnecessary after patterning, from a substrate 1 in a production or an organic electroluminescence device (organic EL device). In particular, it provides a method for producing an organic EL device comprising a step of attaching on the substrate adhesive sheets 6, in particular, an adhesive sheet having an ultraviolet ray curing type pressure sensitive adhesive layer after the patterning, and peeling off the adhesive sheets. According to the method, an organic EL device substantially not containing a partition wall is provided so that the adverse effect of the moisture content and the gas discharged from the partition wall to the device can be prevented, and thus an organic EL device with a long life can be provided.

Abstract: The invention provides a method for removing a resist material existing on an article by adhering a pressure-sensitive adhesive sheet onto the surface of a resist material and releasing both the pressure-sensitive adhesive sheet and the resist material in an integrated state to thereby remove the resist material from the article, in which method the resist material has a Young's modulus of 0.5 MPa or more upon releasing.

Abstract: A process for producing a head slider wherein a floating surface is formed on a slider substrate by photolithography. The process for the production of a head slider has a step of forming, on a slider substrate by photolithography, a patterned floating surface having a resist material on its upper surface; a step of sticking an adhesive sheet on the upper surface of the resist material present on the floating surface; and a step of peeling off the adhesive sheet together with the resist material from the floating surface.

Abstract: In accordance with the production process according to the present invention, a stamper having a desired pattern for the formation of a disc board can be produced without worsening the working atmosphere or causing any other problems. A novel process for the production of a stamper for the formation of a disc board is provided, which comprises applying an adhesive tape to the surface of a stamper body on which an unnecessary resist remains, and then peeling the adhesive tape off the stamper body so that the unnecessary resist is transferred to the adhesive tape to remove itself from the stamper body.
