    • An aperture mask is provided comprising an elongated web of flexible film having at least one deposition mask pattern formed in the film, wherein the deposition mask pattern defines deposition apertures that extend through the film that define at least a portion of one or more electronic circuit elements, and wherein deposition apertures are bounded by a rim, the rim being a portion of the mask which has a thickness greater than an average thickness for the mask. In another aspect, the present invention provides a method of making such an aperture mask comprising the steps of: providing a support surface, wherein the support surface includes a plurality of lowered portions; providing a burner, wherein the burner supports a flame, and wherein the flame includes a flame tip opposite the burner; contacting at least a portion of an elongated web of flexible film against the support surface; and heating the film with a flame from a burner to create apertures in the film in the areas covering the plurality of lowered portions.
    • 提供了一种光阑掩模,其包括具有形成在所述膜中的至少一个沉积掩模图案的柔性膜的细长网,其中所述沉积掩模图案限定延伸穿过所述膜的沉积孔,其限定一个或多个电子电路元件的至少一部分 ,并且其中沉积孔由边缘限定,所述边缘是所述掩模的一部分,其厚度大于所述掩模的平均厚度。 另一方面,本发明提供一种制造这种孔眼掩模的方法,包括以下步骤:提供支撑表面,其中所述支撑表面包括多个下降部分; 提供燃烧器,其中所述燃烧器支撑火焰,并且其中所述火焰包括与所述燃烧器相对的火焰尖端; 将柔性薄膜的细长腹板的至少一部分抵靠支撑表面接触; 并用来自燃烧器的火焰加热膜,以在覆盖多个下降部分的区域中在膜中产生孔。
