Abstract: Disclosed is a variable inductor or inductor module with a varying inductance, wherein the variable inductor or inductor module changes inductor ring spacing and the distance between the inductor and a substrate using a MEMS driver, thereby enabling variances in the inductance.

Abstract: A resonator drive method is provided. The resonator drive method comprises: driving a third electrode that is higher than the first electrode and the second electrode based on an upper surface of the substrate, which are spaced apart from each other at a first interval on a substrate, to descend toward the substrate; and arranging the third electrode between the first electrode and the second electrode to be in contact with the upper surface of the substrate and arranging the first electrode, the second electrode, and the third electrode to be spaced apart from one another at a second interval, wherein the second interval is less than the first interval.

Abstract: Provided is an RF switch device and a method of manufacturing the same and, more particularly, to an RF switch device that improves the on-resistance (Ron) of the RF switch by including an integral or integrally formed P diode. The RF switch device includes a first active region on a first substrate as a first base, a second active region on the first substrate spaced apart from the first active region as a second base, and a gate electrode on the first active region and on the second active region.

Abstract: Provided is a method for coating an implant using heat, and more particularly to a method for coating only the surface of an implant with a biocompatible polymer by using heat while maintaining physical characteristics of the implant. The method for coating an implant using heat according to the present invention may effectively introduce a biocompatible polymer onto a three-dimensional material surface and thus may overcome the spatial limitations of light, and enables mass-coating and thus may be effectively used in the manufacture of an implant coated with a biocompatible polymer.
