ABSTRACT:
A semiconductor memory device of a one-transistor type is manufactured by using a so-called double-layer technology. The device comprises a buried-channel type transistor having normally-off characteristics and a capacitor having normally-on characteristics to provide high integrated density. An insulating layer between two conductive layers for forming the transistor and the capacitor is relatively thick to provide increased breakdown voltage and reduced parasitic capacitance.
