摘要:
The invention relates to a backlight apparatus in use for an LCD, in which a plurality of bar-shaped first LED light sources are arranged on the reflective plate to laterally emit light. A plurality of light shades are arranged above the first light sources. A transparent plate is placed above the light shades. Scattering patterns are formed in the bottom of the transparent plate in positions corresponding to the light shades. A bar-shaped second LED light source is arranged at a side of the transparent plate to emit light into the transparent plate. The light source arranged at the side of the transparent plate prevents the formation of dark areas as a problem in the prior art, thereby enhancing the entire uniformity of light. Then, the backlight apparatus can be maintained thin even when applied to a large-sized LCD.

The invention relates to an LCD backlight apparatus, which includes a light guide plate placed under an LCD panel of the LCD to guide light to the LCD panel. The light guide plate has an even upper surface and a scattering pattern formed in a bottom surface. A plurality of monochromatic light sources are placed in line at a side of the light guide plate to radiate light along the plane direction of the light guide plate between the upper and bottom surfaces of the light guide plate. The light sources are adapted to radiate light beams in a predetermined beam angle so that the light beams reach the scattering pattern only after having propagated a predetermined reference length necessary for forming white light when mixed together. The LCD backlight apparatus can reduce the Bezel width without increasing the thickness of an LCD.

Disclosed herein is a device for driving a LED for a flash of a camera, such as a digital camera or a camera of a mobile phone, which is capable of driving the LED in two modes to reduce power consumption. The LED drive device comprises the LED, a continuous low current driver for continuously supplying current which is lower than or equal to rated current of the LED to the LED, a high-current pulse driver for supplying current which is higher than the rated current of the LED to the LED for a predetermined period of time, and a mode selector for selecting one of the continuous low current driver and the high-current pulse driver to drive the LED. According to the present invention, it is possible to prevent unnecessary power consumption and deterioration of reliability of the LED, and obtain an image of brighter picture quality.

The present invention relates to a method for forming a metal wire in a semiconductor device. The method comprises the steps of forming a lower metal wire on a semiconductor substrate, depositing an insulating film on the lower metal wire, forming a damascene etch pattern in the insulating film, depositing a conductive material on the insulating film so that the conductive material fills the damascene etch pattern, thus forming a conductive layer including step portions, depositing, on the conductive layer, a material having a high etch selective ratio against the conductive material, thus forming an anti-etch film, stripping a part of the anti-etch film by means of a CMP process until the conductive layer is exposed, striping a portion of the conductive layer by means of an etch process using the anti-etch film as an etch mask, and stripping the remaining anti-etch film and conductive layer by means of a CMP process, thus forming a conductive wire with which the damascene etch pattern is filled. Therefore, a large amount of slurry and the usage of a pad depending on a long-time polishing in a CMP process can be reduced. It is thus possible to save a process cost price in development and production of a semiconductor device.

Disclosure is a method for polishing a copper layer and a method for forming a copper layer wiring using the same. The method for polishing the copper layer is carried out through a CMP process by using slurry having a polishing rate of at least 10,000 Å/min. The method for forming the copper layer wiring includes a step of forming a sacrificial layer pattern having a trench on a substrate. Then, the copper layer is continuously formed on a sidewall of the trench, a bottom surface of the trench, and on the sacrificial layer pattern. Then, the copper layer is polished so as to expose a surface of the sacrificial layer pattern by using the method. The copper layer is effectively polished when the method is applied to a polishing process of the copper layer.
