    摘要: An integrated filter including a film bulk acoustic resonator (FBAR) and a surface acoustic wave (SAW) resonator and a method of fabricating the integrated filter. The integrated filter includes: a substrate; a first electrode positioned in a predetermined first area on an upper surface of the substrate; a first piezoelectric layer positioned on the first electrode; a second electrode positioned on the first piezoelectric layer; a second piezoelectric layer positioned in a predetermined second area on the upper surface of the substrate; and at least one inter-digital transducer (IDT) electrode positioned on the second piezoelectric layer. The IDT electrode includes: a first IDT electrode formed in a comb structure on the second piezoelectric layer; and a second IDT electrode formed in a comb structure on the second piezoelectric layer so as to mesh with the first IDT electrode. The first and second piezoelectric layers are formed of an identical material. Thus, an integrated filter which operates in various frequency bands can be made compact.

    摘要: A fluxgate sensor is integrated in a semiconductor substrate. The fluxgate sensor has two bar type soft magnetic cores, or a rectangular-ring type soft magnetic core to form a closed magnetic path on the semiconductor substrate, with an excitation coil formed of a metal layer either of the united structure winding the two bar-type cores or two longer sides of the rectangular-ring type core altogether and substantially in a figure of 8 pattern, or of a separated structure winding the two bar type cores or two longer sides of the rectangular-ring type core in series. Also, a pick-up coil is formed on the two bar-type cores or two longer sides of the rectangular-ring type core, either of the united structure winding the two bar-type cores or two longer sides of the rectangular-type core altogether in a solenoid pattern, or of the separated structure winding the two bar type cores or two longer sides of the rectangular-ring type core in series in a solenoid.
