    Abstract: It is an object to provide a highly reliable semiconductor device, a semiconductor device with low power consumption, a semiconductor device with high productivity, and a method for manufacturing such a semiconductor device. Impurities left remaining in an oxide semiconductor layer are removed without generating oxygen deficiency, and the oxide semiconductor layer is purified to have an extremely high purity. Specifically, after oxygen is added to the oxide semiconductor layer, heat treatment is performed on the oxide semiconductor layer to remove the impurities. In order to add oxygen, it is preferable to use a method in which oxygen having high energy is added by an ion implantation method, an ion doping method, or the like.

    Abstract: A method of preventing toxic gas formation after an implantation process is disclosed. Certain dopants, when implanted into films disposed on a substrate, may react when exposed to moisture to form a toxic gas and/or a flammable gas. By in-situ exposing the doped film to an oxygen containing compound, dopant that is shallowly implanted into the layer stack reacts to form a dopant oxide, thereby reducing potential toxic gas and/or flammable gas formation. Alternatively, a capping layer may be formed in-situ over the implanted film to reduce the potential generation of toxic gas and/or flammable gas.

    Abstract: A method of manufacturing a semiconductor device includes providing semiconductor substrate having trenches and mesas. At least one mesa has first and second sidewalls. The method includes angularly implanting a dopant of a second conductivity into the first sidewall, and angularly implanting a dopant of a second conductivity into the second sidewall. The at least one mesa is converted to a pillar by diffusing the dopants into the at least one mesa. The pillar is then converted to a column by angularly implanting a dopant of the first conductivity into a first sidewall of the pillar, and by angularly implanting the dopant of the first conductivity type into a second sidewall of the pillar. The dopants are then diffused into the pillar to provide a P-N junction of the first and second doped regions located long the depth direction of the adjoining trench. Finally, the trenches are filled with an insulating material.
