抄録(英) High-dielectric BST capacitors for Giga-bit DRAM applications were fabricated in a concave-type integration structure. As an electrode material, Pt was deposited by a DC magnetron sputtering method on the patterned TiO_2/SiO_2/Si substrate. Thin BST films were deposited by both the sputtering and MOCVD method using the LDS system. The oxide storage holes were patterned by the reverse photo of normal stacked nodes. All as-deposited capacitors were annealed at 650℃ in a less oxygen atmosphere. Electrical properties such as capacitance, leakage current were measured. It was observed that there was the limitation of sputtered BST capacitors as the storage holes deepen. However, CVD BST capacitors had good step coverage and electrical properties regardless of the storage hole depths.
