CONSTITUTION: A back light unit includes a plurality of light-emitting diodes(36) for generating lights, a printed circuit board(32) for supporting the light-emitting diodes and controlling emission of lights from the light-emitting diodes, a diffusion plate(38) for diffusing the lights emitted from the light-emitting diodes, and a reflector(34). The reflector is formed in a manner that dispersion particles are mixed with acrylic solution on a portion of the surface of the printed circuit board other than the portion where the light-emitting diodes are formed for reflecting lights reflected by the diffusion plate and inputted to the printed circuit board.

Abstract: PURPOSE: A method for forming a contact of a semiconductor device is provided to be capable of preventing deformation of void by filling a conductive layer into the void. CONSTITUTION: After forming the first interlayer dielectric(14) on a semiconductor substrate(10), a contact hole(C1) is formed by selectively etching the first interlayer dielectric. The resultant structure is polished to expose a void. A conductive layer(30) is filled into the exposed void. After forming the second interlayer dielectric(22) on the resultant structure, a contact hole(C3) is formed by selectively etching the second interlayer dielectric. Then, a conductive layer is filled into the contact hole(C3).
