Abstract
The crystallinity of non-monocrystalline silicon necks that connect monocrystalline silicon hemispherical grains to an underlying electrode on an integrated circuit substrate is increased. Preferably, the non-monocrystalline silicon necks are crystallized. By crystallizing the non-monocrystalline silicon necks, the necks may be made more resistant to breaking and detaching during subsequent cleaning processes. The non-monocrystalline silicon necks preferably are crystallized by thermal annealing after fabrication of the hemispherical grain silicon.
