    摘要: Memory devices and methods for forming a device are disclosed. A substrate prepared with a lower electrode level with bottom electrodes is provided. Fin stack layers are formed on the lower electrode level. Spacers are formed on top of the fin stack layers. The spacers have a width which is less than a lithographic resolution. The fin stack layers are patterned using the spacers as a mask to form fin stacks. The fin stacks contact the bottom electrodes. An interlevel dielectric (ILD) layer is formed on the substrate. The ILD layer fills spaces around the fin stacks. An upper electrode level is formed on the ILD layer. The upper electrode level has top electrodes in contact with the fin stacks. The electrodes and fin stacks form fin-type memory cells.
