Abstract: The present invention is directed to the synthesis of metallic nickel-molybdenum-tungsten films and coatings with direct current sputter deposition, which results in fully-dense crystallographically textured films that are filled with nano-scale faults and twins. The as-deposited films exhibit linear-elastic mechanical behavior and tensile strengths above 2.5 GPa, which is unprecedented for materials that are compatible with wafer-level device fabrication processes. The ultra-high strength is attributed to a combination of solid solution strengthening and the presence of the dense nano-scale faults and twins. These films also possess excellent thermal and mechanical stability, high density, low CTE, and electrical properties that are attractive for next generation metal MEMS applications. Deposited as coatings these films provide protection against friction and wear. The as-deposited films can also be heat treated to modify the internal microstructure and attendant mechanical properties in a way that provides a desired balance of strength and toughness.

Abstract: Representative methods for sealing MEMS devices include depositing insulating material over a substrate, forming conductive vias in a first set of layers of the insulating material, and forming metal structures in a second set of layers of the insulating material. The first and second sets of layers are interleaved in alternation. A dummy insulating layer is provided as an upper-most layer of the first set of layers. Portions of the first and second set of layers are etched to form void regions in the insulating material. A conductive pad is formed on and in a top surface of the insulating material. The void regions are sealed with an encapsulating structure. At least a portion of the encapsulating structure is laterally adjacent the dummy insulating layer, and above a top surface of the conductive pad. An etch is performed to remove at least a portion of the dummy insulating layer.

Abstract: A structure forming method according to an aspect is a structure forming method for forming a first hole and a second hole having width smaller than width of the first hole in a substrate with dry etching and forming a structure. The structure forming method includes forming an etching mask on the substrate, etching a portion of the etching mask overlapping a first hole forming region where the first hole is formed, etching a portion of the etching mask overlapping a second hole forming region where the second hole is formed, and performing the dry etching of the substrate using the etching mask as a mask.

Abstract: The invention is directed to a technique for reducing the time from the start of fabrication of a prototype structure to the completion of fabrication of a real structure. A device processing method includes steps of: fabricating a first structure using an ion beam under a first condition in a first region on a substrate; measuring a size of the first structure which is fabricated; comparing the measurement result with design data; determining a second condition from the comparison result; and fabricating a second structure using the ion beam under the second condition in a second region on the substrate.
