An opposition section of the high-voltage junction terminating region, whose distance to an intermediate-potential region formed of a p-drain region is shorter than those of other sections, is provided with a resistance higher than those of the other sections.

As a result, an erroneous operation or destruction of a logic part of a high-side circuit can be prevented when the negative-voltage surge is applied to an H-VDD terminal or a Vs terminal.

Abstract: A dual gate extremely thin semiconductor-on-insulator transistor with asymmetric gate dielectrics is provided. This structure can improve the sensor detection limit and also relieve the drift effects. Detection is performed at a constant current mode while the species will be detected at a gate electrode with a thin equivalent oxide thickness (EOT) and the gate bias will be applied to the second gate electrode with thicker EOT to maintain current flow through the transistor.

This allows a reduction of the sensor dimension and therefore an increase in the array size. The dual gate structure further includes cavities, i.e., microwell arrays, for chemical sensing.
