Abstract
In an interface device in which by means of a buried insulation film and a region insulation portion an SOI substrate is divided into a semiconductor support substrate region a controller side region and a network side region and a part of isolator circuits and making use of a static capacitance are formed in the network side region the semiconductor support substrate region and the network side region are connected to a network power source to always keep these regions at a same potential, thereby, an interface device using a dielectric isolation substrate which suppresses erroneous operations due to noises and characteristic deterioration, and a system using the same are provided.
