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

Claim 0:
1. A semiconductor device comprising:
a substrate;
a first insulating layer on the substrate;
a plurality of first metal patterns in the first insulating layer;
a second insulating layer on the first insulating layer;
a first via contact in the second insulating layer;
a second metal pattern on the second insulating layer, the second metal pattern electrically connected to one of the plurality of first metal patterns through the first via contact; and
a third insulating layer on the second metal pattern,
wherein the third insulating layer covers a top surface and a side surface of the second metal pattern,
the second metal pattern includes an aluminum (Al) metal pattern and a titanium oxide (TiO2) pattern on the aluminum (Al) metal pattern, and
a thickness of the aluminum (Al) metal pattern of the second metal pattern in a direction that is perpendicular to a top surface of the substrate is greater than a thickness of the one of the plurality of first metal patterns in the direction.
