THREE-DIMENSIONAL MEMORY DEVICE CONTAINING ENGINEERED CHARGE STORAGE ELEMENTS AND METHODS FOR FORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18351205 titled 'THREE-DIMENSIONAL MEMORY DEVICE CONTAINING ENGINEERED CHARGE STORAGE ELEMENTS AND METHODS FOR FORMING THE SAME
Simplified Explanation
The semiconductor structure described in the abstract consists of an alternating stack of insulating layers and electrically conductive layers, with a memory opening that extends vertically through the stack. Within the memory opening, there is a memory opening fill structure containing a vertical semiconductor channel and a memory film. The memory film includes a tunneling dielectric layer, a continuous charge storage material layer that extends vertically through multiple electrically conductive layers, a vertical stack of discrete charge storage elements at different levels of the electrically conductive layers, and a vertical stack of discrete blocking dielectric material portions containing silicon and oxygen atoms.
