摘要:
In a matrix-shaped configuration of memory transistors, word lines are disposed on a top side of a semiconductor body and are parallel to one another. Bit lines run transversely with respect thereto and are formed by polysilicon strips which are applied on the top side and are isolated from the semiconductor body by barrier layers functioning as diffusion barriers.
