PROBLEM TO BE SOLVED: To provide an electrostatic driving type MEMS element on which a driving electrode has an imbedding structure and its manufacturing method. SOLUTION: The driving electrode 320 is formed on a substrate 310 and an insulating layer 330 is further formed on the driving electrode 320 under the manufacturing method for the MEMS element. The insulating layer 330 is etched by patterning in a region where a fixing part and a contact part are formed, and a metal layer 340 is formed on it. The metal layer 340 is flattened by polishing until the insulating layer 330 is exposed. At this time, the driving electrode 320 remains as it is imbedded in the insulating layer 330. Thereafter a sacrifice layer 350 is formed on that and, a region of the sacrifice layer 350 where a fixing part is formed is made into a grouping type space by etching, and the MEMS structure layer 350 is laminated on the remaining sacrifice layer 350.

Abstract:
A method of fabricating a MEMS device includes conditioning of an insulating layer by applying a voltage across the insulating layer via a conductive sacrificial layer for a period of time, prior to removal of the conductive sacrificial layer. This conditioning process may be used to saturate or stabilize charge accumulated within the insulating layer. The resistance across the insulating layer may also be measured to detect possible defects in the insulating layer.

A micro-scale interconnect device with internal heat spreader and method for fabricating same. The device includes first and second arrays of generally coplanar electrical communication lines. The first array is disposed generally along a first plane, and the second array is disposed generally along a second plane spaced from the first plane. The arrays are electrically isolated from each other. Embedded within the interconnect device is a heat spreader element. The heat spreader element comprises a dielectric material disposed in thermal contact with at least one of the arrays and a layer of thermally conductive material embedded in the dielectric material. The device is fabricated by forming layers of electrically conductive, dielectric, and thermally conductive materials on a substrate. The layers are arranged to enable heat energy given off by current-carrying communciation lines to be transferred away from the communciation lines.
