Beam structure is widely used for MEMS (Micro-electromechanical Systems) design, the mechanical properties of beam structure are of great importance to guide the design of MEMS devices. Among the many properties, stress rupture properties are studied in this paper. The sensor based on piezoresistive effect with a specially designed cross-beam structure is proposed for stress rupture properties measurement...
In this paper, an improved chemical foaming process (CFP) for wafer-level glass cavities will be demonstrated for volume production in a clean room. First of all, suitable foaming agents transferring techniques are investigated to avoid powder pollution to the chips in a clean room. In addition, the precise controlling of the sizes of the glass cavities is studied theoretically and experimentally...
Based on self-scrolling of Si/Cr bilayer films on Si(001) wafers, various micro- and nanostructures including micro-claws, microtubes, helical nanobelts, nanorings and nanospirals are fabricated in a controllable way. The scrolling principles of the structures from Si/Cr bilayer films are discussed. The flexibility of individual Si/Cr nanospirals and nanorings has been investigated using a nanorobotic...
