    摘要: Manufacturing yield of integrated circuits having differentiated areas such as array and support areas of a memory is improved by reducing height/step height difference between structures in the respective differentiated areas and is particularly effective in conjunction with top-oxide-early (TOE) and top-oxide-late processes. A novel planarization technique avoids damage of active devices, isolation structures and the like due to scratching, chipping or dishing which is particularly effective to improve manufacturing yield using TON processes and also using TOE and TOL processes when average height/step height is substantially equalized. Alternative mask materials such as polysilicon may also be used to simplify and/or improve control of processes.

    摘要: The present invention provides a semiconductor structure that includes an active wordline located above a semiconductor memory device and a passive wordline located adjacent to said active wordline and above an active area of a substrate. In accordance with the present invention, the passive wordline is separated from the active area by a pad nitride. The present invention also provides methods that are capable of forming the inventive semiconductor structure.
