Abstract
A contact structure having silicide layers, a semiconductor device employing the same, and methods of fabricating the contact structure and semiconductor device are provided. The contact structure includes a first conductive region and a second conductive region on a substrate. An insulating layer covers the first and second conductive regions. A first contact hole and a second contact hole are formed through the insulating layer and expose the first and second conductive regions, respectively. A first silicide layer having a first thickness is on the first conductive region exposed by the first contact hole. A second silicide layer having a second thickness different than the first thickness is on the second conductive region exposed by the second contact hole.
