    摘要： Provided are an interdigitated electrode (IDE) for an electronic device, which includes a plurality of anodes and a plurality of cathodes arranged radially in an alternating fashion for electrical insulation from one another, and an electronic device using the same. The IDE in which the anodes and the cathodes are arranged radially in an alternating fashion is fabricated and applied to the electronic device, so that the entire fabrication process can be simplified compared to that of a typical electronic device in which an upper electrode is different from a lower electrode. Also, circular or polygonal IDEs can be applied to systems that are driven or measure values on their central axes, thereby enhancing the performance and efficiency of the systems. Furthermore, the circular or polygonal IDEs can be employed in systems such as acoustic sensors, pressure sensors, micro-speakers, biological sensors, and acceleration sensors, so that the structure and operation of the systems can be simplified.

    摘要： A micromini condenser microphone having a flexure hinge-shaped upper diaphragm and a back plate, and a method of manufacturing the same are provided.The method includes the steps of: forming a lower silicon layer and a first insulating layer; forming an upper silicon layer to be used as a back plate on the first insulating layer; forming a plurality of sound holes by patterning the upper silicon layer; forming a second insulating layer on the upper silicon layer; forming a conductive layer on the upper silicon layer having the sound holes, and forming a passivation layer on the conductive layer; forming a sacrificial layer on the passivation layer; depositing a diaphragm on the sacrificial layer, and forming a plurality of air holes passing through the diaphragm; forming electrode pads on the passivation layer and a region of the diaphragm; and etching the sacrificial layer, the passivation layer, the conductive layer, the upper silicon layer, the first insulating layer and the lower silicon layer to form an air gap between the diaphragm and the upper silicon layer.Consequently, due to the flexible diaphragm, a manufacturing process using semiconductor MEMS technology may improve the sensitivity of the condenser microphone and reduce the size of the condenser microphone, thereby enabling integration into a portable terminal.

    摘要： Provided is a forced acoustic dipole capable of regulating phases and acoustic pressures of first and second acoustic signals output from first and second pole speakers to freely steer the direction of an acoustic lobe. In addition, a forced acoustic multipole array is constituted by a plurality of forced acoustic dipoles. When the phases and acoustic pressures of the first and second acoustic signals output from the forced acoustic dipoles are regulated to steer an acoustic lobe in a specific direction, sound can be heard from a desired direction only without disturbing others.
