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

Claim 0:
1. A semiconductor device, comprising:
a transistor on a substrate;
an interlayer insulating layer on the transistor;
a first metal-containing layer on the interlayer insulating layer; and
a second metal-containing layer on the first metal-containing layer,
wherein:
the second metal-containing layer includes a resistor,
the resistor includes:
a first insulating layer on the first metal-containing layer;
a resistor metal layer on the first insulating layer; and
a second insulating layer on the resistor metal layer, and

the resistor metal layer includes a curved concave recessed side surface such that a center portion of the side surface of the resistor metal layer extends along a curve and further inwardly in the resistor metal layer than a top portion of the side surface of the resistor metal layer and extends along a curve and further inwardly in the resistor metal layer than a bottom portion of the side surface of the resistor metal layer.
