Patent ID: 11908941
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a semiconductor substrate having isolation regions formed therein;
a fin structure disposed over the semiconductor substrate protruding vertically above the isolation regions and extending laterally in a first direction;
a gate structure disposed over the fin structure, the gate structure including a gate electrode and a gate dielectric; and
a channel region of the fin structure interposed in the first direction between a source region and a drain region,
wherein the channel region comprises an undoped volume inversion region having a shape such that no surface inversion occurs therein when an inversion bias is applied to the gate electrode, wherein the inversion bias is sufficient to form a surface inversion layer when applied to a bulk semiconductor material of the fin structure.
