Abstract: A surface-mounted transformer includes an adhesive layer and a winding product. The winding product is disposed inside the adhesive layer; the winding product includes an I-shaped magnetic core and a coil wound on a middle pillar of the I-shaped magnetic core; leading-out ends of the coil are connected to electrodes; the electrodes are exposed on the surface of the adhesive layer; and the adhesive layer is obtained through compression molding forming of a magnetic molding material. Compared with a surface-mounted transformer in the prior art, which has equal performance indexes, the surface-mounted transformer has a smaller size with a decrease proportion of over 50%; and a BOBBIN and an insulating rubber tape do not need to be used in processing. The winding product in the surface-mounted transformer is completely covered by the adhesive layer, so that the product is high in reliability and can support a PSIP plastic package environment.

Abstract: A microelectromechanical system includes a backplate and a diaphragm. The backplate includes spaced stator elements with voids formed therebetween. The stator element includes a first conductive element. The diaphragm includes a plurality of corrugations facing the voids respectively. Each corrugation includes a groove formed at a surface thereof away from the backplate. The corrugation includes a second conductive element. The diaphragm is moveable with respect to the backplate in response to a pressure exerted thereon to cause the corrugations to be moved into or out of the corresponding voids, thereby changing the capacitance formed between the first and second conductive elements. The corrugations are defined by grooves formed at surfaces away from the backplate, which facilitate to control the compliance of the diaphragm and reduce stiffness of the diaphragm. The corrugation can be formed with lower aspect ratios, which allows it to be formed using standard front side processes.
