Abstract: An image device includes a first active region and a second active region disposed on a substrate. Each of the first active region and the second active region includes a gate insulating layer disposed on the substrate and a gate electrode disposed on the gate insulating layer. At least one of the first active region and the second active region further includes a first passivation layer containing fluorine (F) disposed between the gate insulating layer and the gate electrode. A concentration of fluorine in the gate insulating layer is higher than a concentration of fluorine in the gate electrode.

Abstract: Methods of forming semiconductor devices may be provided. A method of forming a semiconductor device may include patterning first and second material layers to form a first through region exposing a substrate. The method may include forming a first semiconductor layer in the first through region on the substrate and on sidewalls of the first and second material layers. In some embodiments, the method may include forming a buried layer filling the first through region on the first semiconductor layer. In some embodiments, the method may include removing a portion of the buried layer to form a second through region between the sidewalls of the first and second material layers. Moreover, the method may include forming a second semiconductor layer in the second through region.
