  • Publication number: 20140103482
    Abstract: A method of manufacturing a semiconductor device which can prevent leakage current caused by gate electrodes intersecting element isolation layers in a major axis of an active region, and which further has vertical channels to provide a sufficient overlap margin, and a semiconductor device manufactured using the above method. The device includes gate electrodes formed on element isolation layers that are disposed between active regions and have top surfaces that are higher than the top surfaces of the active regions. Since the gate electrodes are formed on the element isolation layers, leakage current in a semiconductor substrate is prevented. In addition, the gate electrodes are formed using a striped shape mask pattern, thereby obtaining a sufficient overlap margin compared to a contact shape or bar shape pattern.

Below a pickup electrode disposed in the high-voltage junction terminating region, a universal contact region in Ohmic contact with the pickup electrode can be disposed. The universal contact region has a p+ region and an n+ region that can be disposed in alternating contact along a surface of the p semiconductor substrate. By disposing the universal contact region in this way, the quantity of carriers flowing into the low-side circuit portion can be reduced when a negative surge voltage is input.
