Provided is a semiconductor device and a method of manufacturing a semiconductor device. In the semiconductor device, high-concentration n type impurity regions are formed respectively below gate electrodes. By setting a gate length to be smaller than a depth of channel regions, pn junction interfaces formed of adjacent side faces of the n type impurity regions and the channel regions can be substantially vertical to a top surface of a base. With this configuration, even when reduction in size is achieved in a super junction structure, a distance between the channel regions (i.e. a current path below the gate electrode) is not reduced unnecessarily. Accordingly, an increase in resistance can be prevented. In addition, depletion layers uniformly expand in the n type semiconductor regions, and impurity concentration of the regions can be increased consequently. Accordingly, reduction in resistance can be achieved.

Bar armor currently provides a means of providing partial protection of vehicles and structures against certain types of Rocket Propelled Grenades (RPGs). However, the individual bars must provide enough strength to cut through or deform the outer ogive of an RPG and cause electrical contact with the inner ogive. This in turn imposes constraints on the overall effectiveness of the system and how light it can be made. These constraints can be eased by providing cross-attachments for the bars, provided that the cross-attachments themselves are of low enough density and sufficient frangibility to avoid detonating the RPG when they are struck by the RPG nosepiece, which contains a piezoelectric element that causes the fuse of the RPG to function. Through this means, bar armor can be made lighter, more effective, and easier to see through.
