PURPOSE:To enable to easily reduce or eliminate the transinterference between electron circuits by a method wherein a part of earthing wirings only is connected to the earthing point of a semiconductor substrate. CONSTITUTION:Two sets of electron circuits 7 and 8 are electrically isolated each other by having isolation structure wherein isolated regions 2, 3, and 4 are contained. On the electron circuit 7, an earthing wiring 400 alone is connected by wiring to an isolation electrode 9 and said earthing wiring is also connected by wiring to the earthing electrode 14 for bonding. On the other hand, the grounding wiring 500 of the electron circuit 8 is not wired in the isolation region located in its vicinity, but instead directly connected to the grounding electrode 14 for bonding in that state. The optical conductive integrated circuit thus wired has a finite impedance on its electric route, but it does not contain R6, R7 and R9. |
