A process for manufacturing a non-volatile memory structure, in particular
of a cross-point type provided with an array of memory cells, including
forming bottom electrodes on a substrate; forming areas of active
material on the bottom electrodes; and forming top electrodes on the
areas of active material. The memory cells are defined at the
intersection of the bottom electrode with the top electrode. At least one
from among the steps of forming bottom electrodes, forming areas of
active material, and forming top electrodes includes using
soft-lithography techniques, chosen from amongst "microtransfer molding",
"micromolding in capillary", and "microcontact printing". According to a
first type of structure, the step of forming areas of active material
includes forming strips of active material in a way self-aligned with
respect to the bottom electrodes or the top electrodes; according to a
different type of structure, the step of forming areas of active material
envisages forming monolayer or multilayer pads between the bottom
electrodes and the top electrodes.
