Abstract
A memory cell array has memory cells in which there is an electrical connection between a polycrystalline semiconductor material of a capacitor electrode and a monocrystalline semiconductor region. Islands made of an amorphous material are disposed in a vicinity of the electrical connection between the polycrystalline semiconductor material and the monocrystalline semiconductor region. The islands are produced in particular by thermally breaking up an amorphous layer which has been formed by thermal oxidation. The memory cell array is in particular a DRAM array with a trench capacitor.
