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

Claim 12:
13. A semiconductor device, comprising:
a substrate;
a first active fin on the substrate, wherein the first active fin comprises a first side surface and a second side surface opposing the first side surface of the first active fin;
a first isolation layer on the first side surface of the first active fin and on the substrate;
a second isolation layer on the second side surface of the first active fin and on the substrate;
a first source/drain that extends from the first active fin;
a contact on and in contact with the first source/drain; and
wherein the first source/drain comprises:
a first portion vertically overlapping the first isolation layer;
a second portion vertically overlapping the first active fin; and
a third portion vertically overlapping the second isolation layer,

wherein the contact comprises a first contact portion vertically overlapping the first source/drain and a second contact portion not vertically overlapping the first source/drain,
wherein a lower end of the first portion of the first source/drain is at a lower level than a lower end of the second portion of the first source/drain,
wherein the second contact portion of the contact vertically overlaps the first isolation layer,
wherein a lower end of the first isolation layer is at a lower level than a lower end of the second isolation layer, and
wherein a portion of the first isolation layer vertically overlapping a side surface of the contact is at a lower level than an upper surface of the second isolation layer.
