A semiconductor device includes: a fin-type active area extending in a first direction protruding from a substrate; a plurality of nanosheet stacked structures; a blocking film covering a part of the upper surface and one sidewall of each of a pair of nanosheet stacked structures adjacent to both sides of the fin-type active area among the plurality of nanosheet stacked structures; a gate electrode extending in a second direction intersecting the first direction on the fin-type active area, the gate electrode including a real gate electrode surrounding the plurality of nanosheets and a dummy gate electrode disposed on the blocking film; and a gate dielectric layer between the real gate electrode and the plurality of nanosheets and between the dummy gate electrode and the blocking film.

Semiconductor devices

An optical recording/reproducing apparatus including a plurality of light sources emitting lights with different wavelengths for use in recording/reproducing information onto/from various types of optical recording media of different recording densities, in which at least two lights emitted from the light sources have polarization components orthogonal to each other; an objective lens for focusing a light from each of the light sources to a corresponding optical recording medium; a collimating lens disposed between the light sources and the objective lens for collimating lights from the light sources; a hologram element installed between the collimating lens and the objective lens for refracting a light emitted from one of the light sources, in which the light to be refracted is selected by wavelength and polarization components; and a photodetector receiving a light that is reflected from the corresponding optical recording medium after being focused by the objective lens.

Optical recording/reproducing apparatus capable of recording/reproducing information onto/from various types of optical recording media of different recording densities and different thicknesses
