System and method for selectively applying electrical energy to structures within or on the surface of a patient’s body and controlling the flow of an electrically conductive fluid from the application site to provide or maintain a desired operating condition of the electrosurgical device. A logical condition decider 13 decides whether the combination of the logical comparison results satisfies a predetermined condition. A silicon layer, SiGe layer, silicon layer, and insulating layer are sequentially formed on the resultant structure to prepare a first substrate. Orifices are inserted at the base ends of the cylinders 86 to provide optimum breakoff pressure for the check valves. A verification process is then executed to verify that the clock unit operates at a precision falling within a predetermined range by confirming that, in the time of the units equal to or larger than the predetermined unit, the acquired time and the received reference time coincide with each other.
