    Abstract: A method of manufacturing a plurality of through-holes (132) in a layer of material by subjecting the layer to directional dry etching to provide through-holes (132) in the layer of material; For batch-wise production, the method comprises
    - after a step of providing a layer of first material (220) on base material and before the step of directional dry etching, providing a plurality of holes at the central locations of pits (210),
    - etching base material at the central locations of the pits (210) so as to form a cavity (280) with an aperture (281),
    - depositing a second layer of material (240) on the base material in the cavity (280), and
    - subjecting the second layer of material (240) in the cavity (280) to said step of directional dry etching using the aperture (281) as the opening (141) of a shadow mask.

    Abstract translation: 一种在材料层中制造多个通孔(132)的方法,通过对该层进行定向干法蚀刻以在该材料层中提供通孔(132) 对于批量生产,该方法包括: - 在基材上提供一层第一材料(220),并在定向干法刻蚀步骤之前,在凹坑(210)的中心位置处提供多个孔, - 在凹坑(210)的中心位置蚀刻基材以形成具有孔(281)的空腔(280); - 在空腔(280)中的基材上沉积第二材料层(240) ,以及 - 使用孔(281)作为荫罩的开口(141),使空腔(280)中的第二材料层(240)经受定向干法蚀刻的所述步骤。
