Abstract

New ZrO₂/Al₂O₃/ZrO₂(ZAZ) dielectric film was theoretically designed and successfully demonstrated to be applicable to 45nm DRAM devices. ZAZ dielectric film is a combined structure from tetragonal ZrO₂ and amorphous Al₂O₃. Thus prepared ZAZ TIT capacitors showed very small Tox.eq value of 6.3Å and low leakage current less than 1fA/cell. It was also confirmed that ZAZ TIT capacitor was thermally robust during backend full thermal process by applying it to the final DRAM product in mass production.
