发明名称 Semiconductor structures, DRAM cells and electronic systems
摘要 The invention includes a method of forming a rugged semiconductor-containing surface. A first semiconductor layer is formed over a substrate, and a second semiconductor layer is formed over the first semiconductor layer. Subsequently, a third semiconductor layer is formed over the second semiconductor layer, and semiconductor-containing seeds are formed over the third semiconductor layer. The seeds are annealed to form the rugged semiconductor-containing surface. The first, second and third semiconductor layers are part of a common stack, and can be together utilized within a storage node of a capacitor construction. The invention also includes semiconductor structures comprising rugged surfaces. The rugged surfaces can be, for example, rugged silicon.
