ABSTRACT:
A dynamic read/write memory cell of the one transistor type is made by a single-level polysilicon process in which the word lines and the gates of the access transistors are formed by the metal strips. No metal-to-silicon or metal-to-polysilicon contacts are needed. The access transistors are made by etching through polysilicon strips which are the capacitor bias plates. The size of the transistor is not determined by alignment accuracy.
