Abstract:
A packet analysis system captures packets propagating through a network, and analyzes the captured packets. The packet analysis has a plurality of terminal node type sensors and a server. Each of the terminal node type sensors captures packets propagating through the network, and classifies the captured packets. A server acquires classification information from at least one of the terminal node type sensors through the network, and generates a whole report of the packet analysis system based the acquired classification information.
Abstract:
In order to apply a predetermined voltage to a silicon layer (3) to control a threshold voltage, a second gate electrode (5) is provided on the surface of the silicon layer (3) with a gate oxide film (insulating layer) (4) interposed therebetween so as to fall within the same surface of the silicon layer (3) as a surface on which a source (7) and a drain (8) placed in the silicon layer (3) and a first gate electrode (6) are disposed.
Abstract:
A semiconductor device includes a source and a drain formed in a device region of a semiconductor substrate, and an electrode withdrawal portion having an impurity concentration higher than that of the device region. The electrode withdrawal portion is formed so as to adjoin either one of the source and drain. An electrode for the source or drain adjacent to the electrode withdrawal portion is used jointly as an electrode for the electrode withdrawal portion.
