    摘要: A semiconductor memory encompasses a memory cell matrix, which embraces device isolation films running along the column-direction, arranged alternatively between the cell columns; first conductive layers having top surfaces lower than the device isolation films; inter-electrode dielectrics arranged on the corresponding first conductive layers, the inter-electrode dielectric has a dielectric constant larger than that of silicon oxide; and second conductive layers running along the row-direction, each of the second conductive layers arranged on the inter-electrode dielectric and the device isolation films so that the second conductive layer can be shared by the memory cell transistors arranged along the row-direction belonging to different cell columns.

    摘要: A method of manufacturing a semiconductor storage device includes providing an opening portion in a plurality of positions in an insulating film formed on a silicon substrate, and thereafter forming an amorphous silicon film on the insulating film, in which the opening portions are formed, and in the opening portions. Then, trenches are formed to divide the amorphous silicon film, in the vicinity of a midpoint between adjacent opening portions, into a portion on one opening portion side and a portion on the other opening portion side. Next, the amorphous silicon film, in which the trenches are formed, is annealed and subjected to solid-phase crystallization to form a single crystal with the opening portions used as seeds, and thereby a silicon single-crystal layer is formed. Then, a memory cell array is formed on the silicon single-crystal layer.
