Abstract
An integrated circuit device including a link point for electrically connecting a plurality of metal layers, comprising a first metal layer, a link insulating layer and a second metal layer. Diffusion barrier may be employed between the link insulator layer and each of the first metal layer and the second metal layer. The metal layers are connected by exposing the link point to a low-power laser for a relatively long pulse width.
