Abstract
A small sized semiconductor device having a high insulating performance between a primary side circuit and a secondary side circuit is realized. A circuit region plural first and second terminal electrodes connected to the circuit region and an insulation-separation region for separating electrically the first terminal electrodes from the second terminal electrodes, and for transmitting signals between the first and the second terminal electrodes are formed onto a semiconductor chip and the insulation-separation region is provided between the first and second terminal electrodes. The interval between the first and the second terminal electrodes on the same semiconductor chip can be separated with high insulating performance.
