Abstract:
The present invention provides a transfer substrate for transferring a metal wiring material to a transfer-receiving object, the transfer substrate comprising a substrate, at least one metal wiring material formed on the substrate and an underlying metal film formed between the substrate and the metal wiring material, wherein the metal wiring material is a molded article prepared by sintering, e.g., gold powder having a purity of 99.9% by weight or more and an average particle size of 0.01 µm to 1.0 µm and the underlying metal film is composed of a metal such as gold or an alloy. The transfer substrate is capable of transferring a metal wiring material to the transfer-receiving object even at a temperature for heating the transfer-receiving object of 80 to 300°C.
Abstract:
In an embodiment a method of fabricating a MEMS structure is provided. The method includes fabricating a working structure (704, 712) in a doped layer (708) proximate a first surface (706) of a silicon substrate. The first surface of the silicon substrate is bonded to a first planar glass structure (116) having a first one or more sacrificial features (104) embedded therein. The method also includes etching to remove a bulk of the silicon substrate, wherein the bulk is reverse of the first surface on the silicon substrate, wherein etching removes the bulk and leaves the working structure bonded to the first planar glass structure. The method also includes etching to remove the first one or more sacrificial features from the first planar glass structure.

Abstract:
The disclosure is generally directed to fabrication steps, and operation principles for microelectromechanical (MEMS) transducers. In one embodiment, the disclosure relates to a texture morphing device. The texture morphing device includes: a plurality of supports arranged on a substrate to support a deformable mirror, an ITO layer; and a Distributed Bragg Reflector (DBR ) layer. A pair of adjacent supports form a cavity with the ITO layer and the deformable mirror. When the height of the cavity changes responsive to an external pressure, the internal reflection within the cavity is changed. The change in the height of the cavity causes the exterior texture to morph. Similar principles are disclosed for constructing sensor and actuators.
