A thermally-grown oxygen-containing layer is formed over a control gate in an NVM region, and a high-k dielectric layer and barrier layer are formed in a logic region. A return path is provided for supplying a magnetic flux to the main pole, and an conductive coil for excitation of the main pole and return path. 006, wherein the dielectric composite material comprises: a polymer resin; and about 10 to about 70 volume percent of cenospheres having a ferric oxide content of less than or equal to 3 weight percent. Advantageously, the inventive particles of cactaceae cladodes are in the form of granules coated with an acid-resistant film soluble in the intestine andor with prolonged release. Since the slit is formed on the passive element, a resonance circuit having a resonance frequency dependant on the shape of the slit is formed on the passive element in the vicinity of the slit, whereby the radiation of the frequency component from the feed element is prevented.
