| 20120056550 | DISPLAY DEVICE - The invention provides an active matrix EL display device which can perform a clear multi-gray scale color display. In particular, the invention provides a large active matrix EL display device at low cost by a manufacturing method which can selectively form a pattern. Power supply lines in a pixel portion are arranged in matrix by the manufacturing method which can selectively form a pattern. Further, capacitance between wirings is reduced by providing a longer distance between adjacent wirings by the manufacturing method which can selectively form a pattern. | 03-08-2012 |
| 20110236755 | ENERGY STORAGE DEVICE AND MANUFACTURING METHOD THEREOF - An electrode of an energy storage device with less deterioration by charge and discharge can be manufactured. In addition, an energy storage device which has large capacity and high endurance can be manufactured. A manufacturing method of an electrode of an energy storage device is provided in which a high-wettability regions and a low-wettability region are formed at a surface of a current collector, a composition containing silicon, germanium, or tin is discharged to the high-wettability regions and then baked to form separate active materials over a surface of the current collector. Thus, an electrode of an energy storage device with less deterioration due to charge and discharge can be manufactured. | 09-29-2011 |
| 20080283916 | Semiconductor substrate, semiconductor device and manufacturing method thereof - It is an object to provide a method for manufacturing a semiconductor substrate in which contamination of a semiconductor layer due to an impurity is prevented and the bonding strength between a support substrate and the semiconductor layer can be increased. An oxide film containing first halogen is formed on a surface of a semiconductor substrate, and the semiconductor substrate is irradiated with ions of second halogen, whereby a separation layer is formed and the second halogen is contained in a semiconductor substrate. Then, heat treatment is performed in a state in which the semiconductor substrate and the support substrate are superposed with an insulating surface containing hydrogen interposed therebetween, whereby part of the semiconductor substrate is separated along the separation layer, so that a semiconductor layer containing the second halogen is provided over the support substrate. | 11-20-2008 |
