Patent ID: 11894298
Assignee: SANDISK TECHNOLOGIES, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A semiconductor structure comprising:
an alternating stack of insulating layers and electrically conductive layers located over a substrate;
memory openings vertically extending through the alternating stack;
memory opening fill structures located in the memory openings, wherein each of the memory opening fill structures comprises a memory film and a vertical semiconductor channel that extend vertically, and each memory film comprises a blocking dielectric metal oxide layer and a vertical stack of silicon oxide liners that are vertically spaced apart, contact a respective one of the insulating layers, and laterally surround the blocking dielectric metal oxide layer; and
dielectric metal oxide layers located between each of the vertically neighboring electrically conductive layers and insulating layers, and located between each of the blocking dielectric metal oxide layers and each of the electrically conductive layers, wherein each of the electrically conductive layers is in direct contact with a respective one of the dielectric metal oxide layers.
