摘要：
A method for manufacturing a micro-structural unit is provided. By the method, micro-machining is performed on a material substrate including first through third conductive layers and two insulating layers, one of which is interposed between the first and the second conductive layers, and the other between the second and the third conductive layers. The method includes several etching steps performed on the layers of the material substrate that are different in thickness.
