    摘要: The invention provides a method for fabricating a memory device having memory cells which are formed on a microstructured driving unit (100), in which method a shaping layer (104) is provided and is patterned in such a manner that vertical trench structures (105) are formed perpendicular to the surface of the driving unit (100). Deposition of a seed layer (106) on side walls (105a) of the trench structures (105) allows a crystallization agent (107) which has filled the trench structures (105), during crystallization, to have grain boundaries perpendicular to electrode surfaces that are to be formed. This provides memory cells based on vertical ferroelectric capacitors in a chain FeRAM structure.

    摘要: A method for fabricating a trench capacitor, that includes steps of: providing a silicon substrate; forming a trench, having a lower region and a surface, in the silicon substrate; and forming a doped layer in the silicon substrate in the lower region of the trench. In addition, a roughened silicon layer that has silicon grains with a diameter ranging from essentially 10 to 100 nm is produced in the lower region of the trench. A dielectric intermediate layer is applied on the roughened silicon layer, and the trench is filled with a doped layer.
