金属电极形成方法和具有金属电极的半导体器件
摘要：
本发明涉及金属电极形成方法和具有金属电极的半导体器件，其中一种金属电极形成方法包括：在衬底(11)上形成基底电极(12)；形成保护膜(13，53)，其在基底电极上具有开口(13a，53a)，以从该开口将基底电极暴露出来；形成覆盖保护膜和开口的金属膜(14，54)；在吸附台(21)上固定衬底，并通过表面形状测量装置(23)测量表面形状；通过形变装置(24)使衬底形变，使得主表面和切削表面之间的差异在预定范围内；测量主表面的表面形状，并判断该差异是否在预定范围内；以及沿该切削表面切削衬底，以将金属膜构图成金属电极(15，55)。
摘要（英）：

The invention relates to a metallic electrode forming method and semiconductor device having metallic electrode. The metallic electrode forming method includes: forming a bed electrode on a substrate; forming a protective film with an opening on the bed electrode to expose the bed electrode from the opening; forming a metallic film covering the protective film and the opening; mounting the substrate on an adsorption stage, and measuring a surface shape of the metallic film by a surface shape measuring means; deforming the substrate by a deforming means so that a difference between the principal surface and a cutting surface is within a predetermined range; measuring a surface shape of the principal surface, and determining whether the difference is within a predetermined range; and cutting the substrate along with the cutting surface so that the metallic film is patterned to be a metallic electrode.
