Abstract
A fusible link and method for its fabrication. A polysilicon pad is formed on top of an insulating layer and covered with a second insulating layer. A trench is selectively etched into the second insulating layer exposing the top of the polysilicon pad. An fusible aluminum link is then formed over the second insulating layer and trench and conformal therewith. When a programming current is driven through the link, the aluminum melts and is absorbed by the polysilicon pad, thereby preventing the link's growback.
