摘要: Apparatuses, devices and methods for fabricating one or more vertically integrated single bit capacitor-based memory cells is disclosed. A single bit capacitor-based memory cell can include a vertically oriented transistor and a vertically oriented capacitor that is vertically integrated with the transistor, so as to form a memory cell. Aspects of the disclosure include process steps for forming the transistor and the capacitor, including a first metal part of a capacitor, a second metal part of a capacitor and an electrically insulating layer disposed between the two. The transistor and the capacitor also include an electrical contact between them and a layer that insulates the transistor from the base layer or the underlying substrate.

摘要: A method of fabricating a bottom electrode includes providing a dielectric layer. An atomic layer deposition is performed to form a bottom electrode material on the dielectric layer. Then, an oxidation process is performed to oxidize part of the bottom electrode material. The oxidized bottom electrode material transforms into an oxide layer. The bottom electrode material which is not oxidized becomes a bottom electrode. A top surface of the bottom electrode includes numerous hill-like profiles. Finally, the oxide layer is removed.
