Abstract
A double-gated MOS type semiconductor memory device having a pair of inverters each of which comprises a bulk MOS transistor formed in a semiconductor substrate and having a first gate electrode on the substrate, and a complementary type MOS transistor stacked over and connected with the bulk MOS transistor, the complementary tyupe MOS transistor being composed of a first insulating film, a semiconductor active layer, a second insulating film and a second gate electrode, laminated upwardly in this order on the first gate electrode, and a process for preparing the double-gated MOS type semiconductor memory device.
