    Abstract: 一種微機電結構及其製造方法,其中的微機電結構包括一個基板以及位在基板上的至少一個懸空微結構。前述懸空微結構包括多層金屬層、至少一層介電層以及至少一邊緣金屬壁。其中,介電層被夾在金屬層之間,而邊緣金屬壁則平行於懸空微結構的厚度方向並圍繞介電層的邊緣。上述邊緣金屬壁可阻擋製程中的蝕刻液蝕刻介電層,而金屬層複合介電層之結構則可以增加懸空微結構在厚度方向上的結構強度。

    Abstract: A micromechanical component for a sensor and/or microphone device. The component has an adjustable first actuator electrode suspended on a regionally deformable first layer, a first stator electrode fastened so that a first measuring signal is able to be tapped with regard to a first voltage or capacitance applied between the first actuator electrode and the first stator electrode, and a second actuator electrode, so that a second measuring signal is able to be tapped with regard to a second voltage or capacitance applied between the second actuator electrode and the first stator electrode or between the second actuator electrode and the second stator electrode. The second actuator electrode is situated in an adjustable manner on a side of the first actuator electrode facing away from the first layer in that the second actuator electrode is suspended on the first actuator electrode and/or an at least regionally deformable second layer.

    Abstract: A method including fusion bonding a handle wafer to a first side of a device wafer. The method further includes depositing a hardmask on a second side of the device wafer, wherein the second side is planar. An etch stop layer is deposited over the hardmask and an exposed portion of the second side of the device wafer. A dielectric layer is formed over the etch stop layer. A via is formed within the dielectric layer. The via is filled with conductive material. A eutectic bond layer is formed over the conductive material. Portions of the dielectric layer uncovered by the eutectic bond layer is etched to expose the etch stop layer. The exposed portions of the etch stop layer is etched. A micro-electro-mechanical system (MEMS) device pattern is etched into the device wafer.
