摘要:
A system for fabricating an ultra-thin composite dielectric, usable for the capacitor in DRAM and in other integrated circuits, involving the deposition, a LPCVD tube, of a nitride (3) in situ on a very thin LPCVD oxide (2). By re-oxidizing the nitride (3) or depositing a LPCVD oxide layer (4, 4′) in situ thereon, a composite ONO dielectric, having very low defect density and good overall electric properties, of less than 10 nm in thickness and as low as 4.5 nm, may be formed.
