Abstract:
PROBLEM TO BE SOLVED: To provide small-sized RF components. SOLUTION: A plurality of components for guiding or controlling RF and microwave radiation are integrated by a plurality of electrodepositions and/or a plurality of laminated materials. The components include a switch, a dielectron an antenna, a transmission line, a filter, a hybrid coupler, an antenna array and/or other active or passive components. The components include a channel that does not allow useful radiated rays to be outputted and input when separating sacrifice materials from composition materials. In a preferred forming process, the electrodeposition mold fabrication technology (e.g., selective deposition, bulk deposition, etching process and flattening process) and post deposition process (e.g., selective etching and/or final backfill process) are employed.

Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of reducing the number of steps for masking in manufacturing a MEMS device. SOLUTION: A layer or a plurality of layers are deposited on a base layer 100. The uppermost layer of the one layer or the plurality of layers is a sacrificial layer 102. A pattern is formed on the sacrificial layer 102, and a photosensitive polymer is stacked thereon and exposed for forming ridges 106. Since the sacrificial layer acts as a photomask, an additional masking step is not required. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A cantilever having a step-up structure and a method of manufacturing the same. The cantilever includes a substrate, an anchor formed on the substrate, and a moving plate connected to the anchor while maintaining a predetermined gap from the substrate. The anchor includes a first anchor of a predetermined shape and a second anchor perpendicular to an edge of the first anchor while being formed along a longitudinal axis of the moving plate. Accordingly, a deformation of the cantilever caused by the high temperature and pressure in a manufacturing process thereof is considerably reduced. As a result, the yield rate of the cantilever is improved, and the reliability of a product using the cantilever is also improved.
