Abstract
The invention provides a microelectronic device comprising at least two memory cells each comprising a so-called selection transistor and a memory element associated with said selection transistor, each transistor comprising a channel in the form of a wire extending in a first direction (x), a gate bordering said channel, a source extending in a second direction (y), and a drain connected to the memory element, said transistors being stacked in a third direction (z) and each occupying a given altitude level in the third direction (z), the microelectronic device wherein the source and the drain are entirely covered by spacers projecting in the third direction (z) in a plane (xy). The invention also provides a method for manufacturing such a device.
