20100233881	METHOD OF MANUFACTURING SUPPORTING STRUCTURES FOR STACK CAPACITOR IN SEMICONDUCTOR DEVICE - A method of manufacturing a supporting structure for a stack capacitor in a semiconductor device is provided. The method includes the following steps. The first step is providing a multi-layer structure including an etching stop layer, a silicon oxide layer and a silicon nitride layer. The second step is etching the silicon nitride layer and the silicon oxide layer to form a plurality of filling recesses in the silicon oxide layer, in which each the filling recess has a lateral surface and a bottom surface. The third step is forming a protecting layer at each the lateral surface. The fourth step is etching the silicon oxide layer to expose the etching stop layer. The fifth step is removing the protecting layer on the each lateral surface, thereby forming the supporting structure.	09-16-2010

20090185372	LED flat lamp - An LED flat lamp including a housing with a light-emitting area at the bottom thereof. The internal side thereof undergoes a reflexion treatment. At least one LED is disposed within the housing. A power connector is extended from the LED to the outside. The LED is installed on a circuit board. A light guide plate is installed at one side of the LED within the housing. The light exit side of the light guide plate is provided with a microstructure for a uniform light exit. Moreover, an optical film unit is attached to the bottom of the light guide plate such that the light-emitting area of the housing is covered with the optical film unit. The optical film unit consists of one or several brightness enhancement films and one or several diffusers. In this way, the problem of glaring light directly emitted by the prior art is resolved. The LED flat lamp in accordance with the invention can emit a non-glaring light and can be modularized into a standardized product.	07-23-2009
