The inventive concepts provide semiconductor devices and methods for manufacturing the same in which the method includes forming a capacitor including a bottom electrode, a dielectric layer and a top electrode sequentially stacked on a substrate, and also where formation of the top electrode includes forming a first metal nitride layer on the dielectric layer, and forming a second metal nitride layer on the first metal nitride layer, in which the first metal nitride layer is disposed between the dielectric layer and the second metal nitride layer, and the first metal nitride layer is formed at a temperature lower than a temperature at which the second metal nitride layer is formed.

A trialkylsilane-based silicon precursor compound may be expressed by Si(R)X, i=1-3, where each of 'R', 'R', and &#x201c;R&#x201d; is a hydrogen or an alkyl having 1-5 carbon(s), all of &#x201c;R&#x201d;, &#x201c;R&#x201d;, and &#x201c;R&#x201d; are not hydrogen, &#x201c;X&#x201d; is one of hydrogen, a hydroxyl group, an amide group, an alkoxide group, a halide group, or Si(R*), and &#x201c;R*&#x201d; is a hydrogen or an alkyl group having 1&#x2dc;5 carbon(s).

Disclosed herein is a light-responsive photocatalyst composition, which is a composite oxide semiconductor containing tungsten, and which can efficiently absorb visible light emitted from the sun and light emitted from interior lamps, such as fluorescent lamps, etc., and a method of preparing the light-responsive photocatalyst composition. The visible light-responsive photocatalyst composition can decompose volatile organic compounds or harmful organic matter causing sick house syndrome, even indoors, because it can be activated by visible light outdoors and can respond to light emitted from interior lamps, such as fluorescent lamps, etc.
