Abstract: PURPOSE: A method for fabricating a sound detection device is provided to reduce a fabricating cost by forming a metallic top electrode instead of a thick top electrode including polycrystalline silicon and a nitride oxide layer. CONSTITUTION: A silicon oxide layer(110) and a silicon nitride layer(120) are sequentially formed on a top part and a bottom part of a silicon substrate(100), respectively. A bottom electrode(131) is formed on a part of the silicon nitride layer. A first photoresist layer is formed on the silicon nitride layer and the lower electrode. A plurality of grooves are formed by etching the first photoresist layer. A seed layer is formed on the first photoresist layer and the grooves. The second photoresist layer is formed on the seed layer. A plurality of groove regions are formed by removing partially the second photoresist layer. A plurality of small grooves are formed on the bottom electrode. A metal layer is deposited on the grooves and the small grooves. A membrane is formed by etching sequentially the silicon nitride layer, the silicon oxide layer, and the silicon substrate. A top electrode(190) having a plurality of air holes(191) is formed by removing partially the first and the second photoresist layers and the seed layer.

Abstract: PURPOSE: A method for manufacturing a low temperature sintering piezoelectric composition is provided to improve a physical property of a piezoelectric material composed of a substituted piezoelectric composition and to decrease a sintering temperature. CONSTITUTION: Mass regarding a composition of either a substituted low temperature sintering PZT-based piezoelectric material or composite 3-component low temperature sintering PZT-based piezoelectric material, is measured. The low temperature sintering PZT-based piezoelectric compositions of which mass is measured, are mixed while calcined. Mass of BaO-CuO as a low temperature sintering agent is measured and mixed with the calcined low temperature sintering PZT-based piezoelectric composition. The low temperature piezoelectric composition is heated to a predetermined temperature and sintered. An electrode is formed on the sintered low temperature piezoelectric material, and an electric field is applied to perform a polarization process. Power is applied to the electrode to determine a physical property of the low temperature piezoelectric material.

Abstract: PURPOSE: A printer head is provided to reduce the size of the device a half when trying to obtain the same displacement since the displacement can be improved more than two times with the same material and driving voltage. CONSTITUTION: A printer head unit including an ink chamber and a nozzle is composed of a diaphragm covered with the ink chamber of the printer head unit, a piezoelectric film repeatedly arranged on the upper part of the diaphragm at a regular interval to form polarization in the same direction as a diaphragm face and an electrode repeatedly formed in a space between the both ends of the piezoelectric film. Herein, an electrode material(113) is sprayed in an empty space of a photo register by using a metal mask, and the remaining photo register is removed after spraying the electrode material. Then the electrode(113) is repeatedly formed in a series along with the piezoelectric film(107) and a silicon film(101).
