摘要:
In order to form a plurality of semiconductor elements over an insulating surface, in one continuous semiconductor layer, an element region serving as a semiconductor element and an element isolation region having a function to electrically isolate element regions from each other by repetition of PN junctions. The element isolation region is formed by selective addition of an impurity element of at least one or more kinds of oxygen, nitrogen, and carbon and an impurity element that imparts an opposite conductivity type to that of the adjacent element region in order to electrically isolate elements from each other in one continuous semiconductor layer.

Although an organic resin substrate is highly effective at reducing the weight and improving the shock resistance of a display device, it is required to improve the moisture resistance of the organic resin substrate for the sake of maintaining the reliability of an EL element. Hard carbon films are formed to cover a surface of the organic resin substrate and outer surfaces of a sealing member. Typically, DLC (Diamond like Carbon) films are used as the carbon films. The DLC films have a construction where carbon atoms are bonded into an SP3 bond in terms of a short-distance order, although the films have an amorphous construction from a macroscopic viewpoint. The DLC films contain 95 to 70 atomic % carbon and 5 to 30 atomic % hydrogen, so that the DLC films are very hard and minute and have a superior gas barrier property and insulation performance.

A photovoltaic device uses a single crystal or polycrystalline semiconductor layer which is separated from a single crystal or polycrystalline semiconductor substrate as a photoelectric conversion layer and has a SOI structure in which the semiconductor layer is bonded to a substrate having an insulating surface or an insulating substrate. A single crystal semiconductor layer which is a separated surface layer part of a single crystal semiconductor substrate and is transferred is used as a photoelectric conversion layer and includes an impurity semiconductor layer to which hydrogen or halogen is added on a light incidence surface or on an opposite surface. The semiconductor layer is fixed to a substrate having an insulating surface or an insulating substrate.
