Semiconductor integrated memory manufacturing method and device

摘要

A method of manufacturing a semiconductor integrated memory device including a plurality of a memory cells, and the semiconductor memory device, wherein each memory cell includes a transistor and a capacitor. The capacitor is formed of first and second electrodes and a dielectric layer. The first electrode and the dielectric layer are successively formed on a main surface of a semiconductor substrate by epitaxial growth. A region of the capacitor is removed to expose a region of the main surface of the substrate under the capacitor. A single crystal semiconductor layer is formed on the exposed region of the substrate by epitaxial growth, and the transistor is formed on the single crystal semiconductor layer, thereby to obtain a device having high integration density integration and preferred performance with high yield.
