    摘要: A MEMS RF-switch is provided for controlling switching on/off of transmission of AC signals. The MEMS RF-switch of the present invention includes: a first electrode coupled to one terminal of the power source; a semiconductor layer combined with an upper surface of the first electrode, and forming a potential barrier to become insulated when a bias signal is applied from the power source; and a second electrode disposed at a predetermined distance away from the semiconductor layer, and being coupled to the other terminal of the power source, wherein the second electrode contacts the semiconductor layer when a bias signal is applied from the power source. Therefore, although the bias signal may not be cut off, free electrons and holes are recombined in the semiconductor layer, whereby charge buildup and sticking can be prevented.

    摘要: A spring structure for supporting a floating member and a micro-structure having the same. The spring structure includes: at least one support post unit fixed to a substrate; and at least one spring unit having a first spring connected to the support post unit and extending in a predetermined direction from the support post unit, a second spring member connected to a floating member and extending in the same direction as the first spring unit from the floating member, and a connection member arranged normal to the first and second spring members and interconnecting the tip ends of the first and second spring members. Because the first spring member and the second spring member are arranged to be expanded or contracted along with the floating member when the temperature changes, the first and second spring members are not subject to stress caused due to the difference in thermal expansion coefficient.

The micro thin-film structure includes at least two thin-films having different properties and laminated in sequence to form an upper layer and a lower layer, wherein an interface between the upper and lower layers is formed to be oriented to at least two directions. The micro thin film structure, and method of forming, may be applied to a movable electrode of an MEMS switch. The thin-film structure may be formed by forming through-holes in the lower layer, and depositing the upper layer in the form of being engaged in the through-holes. Alternatively, the thin-film structure may be made by forming prominence and depression parts on the top side of the lower layer and then depositing the upper layer on the top side of the lower layer having the prominence and depression parts.
