| 20090160034 | MESA SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - The invention provides a mesa semiconductor device and a method of manufacturing the same which minimize the manufacturing cost and prevents contamination and physical damage of the device. An N− type semiconductor layer is formed on a front surface of a semiconductor substrate, and a P type semiconductor layer is formed thereon. An anode electrode is further formed on the P type semiconductor layer so as to be connected to the P type semiconductor layer, and a mesa groove is formed from the front surface of the P type semiconductor layer deeper than the N− type semiconductor layer so as to surround the anode electrode. Then, a second insulation film is formed from inside the mesa groove onto the end portion of the anode electrode. The second insulation film is made of an organic insulator such as polyimide type resin or the like. The lamination body made of the semiconductor substrate and the layers laminated thereon is then diced along a scribe line. | 06-25-2009 |
| 20090160035 | MESA SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - The invention provides a mesa semiconductor device and a method of manufacturing the same which enhance the yield and productivity. An N− type semiconductor layer is formed on a front surface of a semiconductor substrate, and a P type semiconductor layer is formed thereon. An anode electrode is further formed on the P type semiconductor layer so as to be connected to the P type semiconductor layer, and a mesa groove is formed from the front surface of the P type semiconductor layer deeper than the N− type semiconductor layer so as to surround the anode electrode. Then, a second insulation film is formed from inside the mesa groove onto the P type semiconductor layer on the outside of the mesa groove.

| 20090309194 | MESA TYPE SEMICONDUCTOR DEVICE AND MAUFACTURING METHOD THEREOF - This invention is directed to solving problems with a mesa type semiconductor device, which are deterioration in a withstand voltage and occurrence of a leakage current caused by reduced thickness of a second insulation film on an inner wall of a mesa groove corresponding to a PN junction, and offers a mesa type semiconductor device of high withstand voltage and high reliability and its manufacturing method. After the mesa groove is formed by dry-etching, wet-etching with an etching solution including hydrofluoric acid and nitric acid is further applied to a sidewall of the mesa groove to form an overhang made of the first insulation film above an upper portion of the mesa groove. The overhang serves as a barrier to prevent the second insulation film formed in the mesa groove and on the first insulation film around the mesa groove beyond an area of the overhang from flowing toward a bottom of the mesa groove due to an increased fluidity resulting from a subsequent thermal treatment. As a result, the inner wall of the mesa groove corresponding to the PN junction is covered with the second insulation film thick enough to secure a desired withstand voltage and to reduce a leakage current. | 12-17-2009 |

| 20110101796 | VIBRATION ACTUATOR - A vibration actuator includes a coil that extends in a vibration direction and has a flat shape and a magnet that extends in the vibration direction and has a flat shape, so that a case can be made flat or low profile. A weight portion is supported by a shaft, so that, when a drop impact is applied, the weight portion can move along the shaft and the weight portion is not freely moved in the case. A coil spring is disposed between a spring receiving portion and a weight portion. Therefore there is no unnecessary space in the case, so that space can be saved and the vibration actuator can be made compact. | 05-05-2011 |
