Stencil mask and method of producing the same

摘要

To provide a stencil mask that the heat generated in the surface of the stencil mask can be radiated to a supporting substrate supporting a portion around the edge of a thin film quickly and a method of producing the same. A stencil mask has a thin film having an aperture pattern and a supporting substrate supporting a portion around the edge of a thin film and a method of producing the same, and a stencil mask and the method of producing the same has an aspect that a plug that having heat conductance higher than that of a thin film and a supporting substrate is embedded in a state of contacting a thin film and reaches inside of a supporting substrate.
