The invention relates to a layered micro-electronic and/or micro-mechanic structure, comprising at least three alternating electrically conductive layers with insulating layers between the conductive layers. There is also provided a via in a first outer layer, said via comprising an insulated conductive connection made of wafer native material through the layer, an electrically conductive plug extending through the other layers and into said via in the first outer layer in order to provide conductivity through the layers, and an insulating enclosure surrounding said conductive plug in at least one selected layer of said other layers for insulating said plug from the material in said selected layer. It also relates to micro-electronic and/or micro-mechanic device comprising a movable member provided above a cavity such that it is movable in at least one direction. The device has a layered structure according to the invention. Methods of making such a layered MEMS structure is also provided.
