A pilot-type water discharging/stopping and flow regulating valve device capable of performing both the discharging/stopping of water and the regulation of flow by light operations, and capable of, once the flow is regulated, discharging the water at a pre-regulated specified flow in the next water discharge even if the water is stopped.The pilot type water discharging/stopping and flow regulating valve device has a main valve, a back pressure chamber, an introducing small hole, a pilot channel and a flow regulating mechanism. The flow of the main channel is regulated by advancing and retreating the main valve following the advance/retreat of a pilot valve. The valve device further has a water discharging/stopping switching mechanism that switches between the discharging and stopping of water by advancing and retreating the pilot valve between a water discharge position and a water stop position. Furthermore, the flow regulating mechanism is configured to maintain the flow regulating position of the pilot valve at a previously regulated flow regulating position when the water discharging/stopping switching mechanism causes the pilot valve to perform water discharging operation after causing the pilot valve to perform water stopping operation.

A drain diffusion layer 11b includes a low impurity concentration region 5a and a high impurity concentration region 5b, and the low impurity concentration region 5a is located on the channel region side. An impurity layer 7 having an opposite conductivity type to the drain diffusion layer 11b is formed in the channel region, at a position away from the low impurity concentration region 5a by a distance T. Alternatively, the low impurity concentration region 5a and the impurity layer 7 are located so as to contact each other. Still alternatively, a border impurity layer is provided between the low impurity concentration region 5a and the impurity layer 7. Thus, a semiconductor device including a high voltage transistor capable of suppressing the reduction of the electric current driving capability and performing stable driving, and a method for fabricating the same, can be provided.
