Abstract(in English) This paper describes that, being based on 0.6μm SOI-CMOS process of X-FAB having an MOSFET structure with a high breakdown voltage using a long asymmetric LDD structure and thick gate oxide at the drain side, we design two kinds of the MOSFET channel lengths (i.e. the base widths of the parasitic lateral BJT which is inherent to the MOSFETs) and evaluate both current characteristics for the MOSFETs and the lateral BJTs. We measure the drain (collector)-source (emitter) currents for the fabricated MOSFETs as the following three cases: (1) the behavior of making the MOSFETs "on" while letting the lateral BJTs "inactive," (2) the behavior of making the lateral BJTs "active" while letting the MOSFETs "off," and (3) the most significant joint behavior of making the MOSFET "on" and the lateral BJT "active." Moreover, we analyze the above measured current data of the joint behavior compared to those of other two behaviors.
