A method of fabricating a semiconductor light emitting device includes forming a first conductivity type semiconductor layer, forming an active layer by alternately forming a plurality of quantum well layers and a plurality of quantum barrier layers on the first conductivity type semiconductor layer, and forming a second conductivity type semiconductor layer on the active layer. The plurality of quantum barrier layers include at least one first quantum barrier layer adjacent to the first conductivity type semiconductor layer and at least one second quantum barrier layer adjacent to the second conductivity type semiconductor layer. The forming of the active layer includes allowing the at least one first quantum barrier layer to be grown at a first temperature and allowing the at least one second quantum barrier layer to be grown at a second temperature lower than the first temperature.

Disclosed herein are a coating solution for the formation of a dielectric thin film and a method for the formation of a dielectric thin film using the coating solution. The coating solution comprises a titanium alkoxide, a β-diketone or its derivative, and a benzoic acid derivative having an electron donating group. The method comprises spin coating the coating solution on a substrate to form a thin film and drying the thin film at a low temperature to crystallize the thin film. The titanium-containing coating solution is highly stable. In addition, the coating solution enables formation of a thin film, regardless of the kind of substrates, and can be used to form dielectric thin films in an in-line mode in the production processes of PCBs.

A method for manufacturing a semiconductor device. In one example embodiment, a method for manufacturing a semiconductor device includes various steps. First, a dielectric layer is formed on the whole surface of a semiconductor substrate that includes an upper surface of a transistor. Next, a trench and a contact hole are formed by etching the dielectric layer so that the upper surface of the transistor is exposed. Then, a contact is formed by embedding a first conductive layer in the contact hole. Next, an etching stop layer is selectively forming on an upper part of the contact. Then, the semiconductor device is blanket-etched such that the first conductive layer remains in the trench. Next, the etching stop layer is removed. Finally, a metal line is formed by embedding a second conductive layer in the trench.
