There is provided a communication system, comprising: a base station unit that is mounted on a flight vehicle, forms a wireless communication area by radiating a beam to a ground, and communicates wirelessly with a user terminal in the wireless communication area; a processing server unit that is communicatively connected to the base station unit and provides a service to the user terminal in the wireless communication area: a closed-network core unit that provides a mobile communication service of a closed-area network in the wireless communication area formed by the base station unit. The processing server unit may be mounted on the flight vehicle and the closed-network core unit may be arranged in a closed-network core apparatus arranged on the ground.

Communication system

In an LCD driver, in a high voltage resistant MISFET, end portions of a gate electrode run onto electric field relaxing insulation regions. Wires to become source wires or drain wires are formed on an interlayer insulation film of the first layer over the high voltage resistant MISFET. At this moment, when a distance from an interface between a semiconductor substrate and a gate insulation film to an upper portion of the gate electrode is defined as 'a', and a distance from the upper portion of the gate electrode to an upper portion of the interlayer insulation film on which the wires are formed is defined as 'b', a relation of a&#x3e;b is established. In such a high voltage resistant MISFET structured in this manner, the wires are arranged so as not to be overlapped planarly with the gate electrode of the high voltage resistant MISFET.
