Abstract
A master-slice semiconductor integrated circuit device includes a substrate for an input/output circuit section, which is segmented into a plurality of segments during a master processing step. In a slice processing step, slice cells are formed, using different substrate segments. Input/output circuits are formed by respective slice cells so that desired different supply voltages can be applied to input/output circuits on different substrate segments.
