Patent ID: 11908892
Assignee: NATIONAL TAIWAN UNIVERSITY
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 11:
12. A device comprising:
a source region;
a drain region separated from the source region along a first direction; and
a channel structure interposing the source region and the drain region, the channel structure comprising alternately stacking first semiconductor layers and second semiconductor layers, wherein when viewed in a cross section taken along a second direction perpendicular to the first direction, the first semiconductor layers have opposite first and second side surfaces, the second semiconductor layers have opposite third and fourth side surfaces, the third side surfaces of the second semiconductor layers are aligned with the first side surfaces of the first semiconductor layers, and the fourth side surfaces of the second semiconductor layers are laterally set back from the second side surfaces of the first semiconductor layers, wherein the second semiconductor layers of the channel structure electrically connect the source region to the drain region.
