    • Method for manufacturing dynamic RAM one-transistor storage cells in a semiconductor chip with each cell having one integrated field effect transistor and one integrated capacitor. A semiconductor substrate surface is covered in part by a thin oxide layer and in part by a thick oxide structure. The thin oxide layer is subjected to a first ion implantation. A doped polycrystalline semiconductor material is deposited over the entire surface. The polycrystalline layer is structured by means of a photoresist mask and the underlying layers at the open places etched away to expose substrate surface. The mask is removed. A second thin oxide layer is created by oxidation over the entire surface. A second ion implantation implants ions in the second oxide layer. A second doped layer of polycrystalline material is deposited over the second layer. The second polycrystalline layer is structured by a suitable phototechnique to produce a polycrystalline structure semiconductor layer.
