Classification: CPC H | IPC H

Claim 0:
1. A method of forming an electronic device, the method comprising:
forming an opening in a memory stack comprising alternating layers of a first material layer and a second material layer, the memory stack on a common source line;
recessing the second material layer through the opening to form a first recessed region adjacent a sidewall surface of the second material layer;
forming a deposition enabling layer (DEL) on in the first recessed region, the deposition enabling layer (DEL) comprising polysilicon and having a hydrogen-terminated surface;
recessing the deposition enabling layer (DEL) to remove a portion of the deposition enabling layer (DEL) and form a second recessed region adjacent the sidewall surface of the second material layer and to expose a sidewall surface of the common source line and a bottom surface of the opening; and
selectively depositing a trap layer in the second recessed region on the hydrogen-terminated surface of the deposition enabling layer (DEL), on the sidewall surface of the common source line, on the bottom surface of the opening in the memory stack, and not on a sidewall surface of the first material layer.
