微机械部件及微机械部件的制造方法
摘要：
本发明涉及一种微机械部件，具有：基片(10)，其具有空穴(12)，所述空穴向内构造在所述基片的功能性上侧(10a)中；至少部分导电的薄膜(24)，其至少部分地张紧所述空穴；以及对应电极(42)，其间隔开地布置在所述薄膜的从基片远离地指向的外侧上，以使在对应电极和至少部分导电的薄膜之间存在自由空间(52)；所述至少部分导电的薄膜张紧在至少一个至少部分地覆盖所述基片的功能性上侧的电绝缘材料上或其上方；和至少一个压力入口(56)构造在空穴上，以使所述至少部分导电的薄膜利用从所述微机械部件的外部环境流入到所述空穴中的气体介质可向内弯曲到所述自由空间中。本发明还涉及一种微机械部件的制造方法。
摘要（英）：

A micromechanical component includes a substrate (10) having a cavern (12) structured into the functional upper side (10a) of the substrate, an at least partially conductive diaphragm (24), which at least partially spans the cavern, and a counter electrode (42), which is situated on an outer side of the diaphragm oriented away from the substrate so that a clearance (52) is present between the counter electrode and the at least partially conductive diaphragm, the at least partially conductive diaphragm being spanned onto or over at least one electrically insulating material which at least partially covers the functional top side of the substrate, and at least one pressure access (56) being formed on the cavern so that the at least partially conductive diaphragm is bendable into the clearance when a gaseous medium flows from an outer surroundings of the micromechanical component into the cavern. Also described is a manufacturing method for a micromechanical component.
