Abstract
In order to form a cavity for a fusible link in a semiconductor device, an etchable material is applied over and around a portion of the fusible link and the etchable material is coated with a protection layer. The access abutting the etchable material is formed through the protection layer. After the removal of the etchable material, the access is partially filled with a refilling material to thereby form the cavity.
