20080231345 | Silicon Wafer For Semiconductor With Powersupply System on the Backside of Wafer - Disclosed is a semiconductor silicon wafer having an electric power supply affixed to the backside of the wafer. By fabricating the electric power supply onto the backside of the wafer that has been left unused, the semiconductor chip can have a self-supplied power, realizing the self-powered semiconductor chip with an increased efficiency. Further, since the electric power supply is installed on the wafer, not the semiconductor chip, the fabrication procedure becomes very simple, and the battery can be mounted on any type of chip. | 09-25-2008 |
20090071577 | PROCESS FOR MAKING TI-NI BASED FUNCTIONALLY GRADED ALLOYS AND TI-NI BASED FUNCTIONALLY GRADED ALLOYS PRODUCED THEREBY - The present invention relates to Ti—Ni based functionally graded alloys easy in proportional control, which are made by cold working and annealing Ti—Ni based alloys under a predetermined temperature gradient. The thus processed Ti—Ni based functionally graded alloys have a shape memory effect and an ultra elasticity and at the same time, have a consecutive variation of shape depending on a temperature variation. | 03-19-2009 |
20110193238 | SILICON WAFER FOR SEMICONDUCTOR WITH POWERSUPPLY SYSTEM ON THE BACKSIDE OF WAFER - A battery mounted semiconductor device is provided. A battery mounted semiconductor device comprises a semiconductor silicon wafer, an electric power supply formed on a backside of the semiconductor silicon wafer and a circuit pattern formed on a front side of the semiconductor silicon wafer. | 08-11-2011 |
20120264012 | ELECTRODE AND A PRODUCTION METHOD THEREFOR - Disclosed is an electrode. The electrode comprises an active material in the form of a powder, and an electrically conductive material based on a shape-memory alloy. Consequently, damage to the electrode can be minimised and electrode life is improved. | 10-18-2012 |
20120291864 | SOLAR CELL AND SOLAR CELL FABRICATION METHOD - A solar cell is provided. The solar cell includes a substrate which converts light energy into electric energy, a hole which penetrates through the substrate in a vertical direction, and an upper electrode which has a radial pattern with reference to the hole on a surface of the substrate. | 11-22-2012 |
