Abstract:
This disclosure provides a method of fabricating a semiconductor stack and associated device, such as a capacitor and DRAM cell. In particular, a bottom electrode has a material selected for lattice matching characteristics. This material may be created from a relatively inexpensive metal oxide which is processed to adopt a conductive, but difficult-to-produce oxide state, with specific crystalline form; to provide one example, specific materials are disclosed that are compatible with the growth of rutile phase titanium dioxide (TiO2) for use as a dielectric, thereby leading to predictable and reproducible higher dielectric constant and lower effective oxide thickness and, thus, greater part density at lower cost.
