An integrated circuit, a contact and a method of manufacture therefor. The integrated circuit has a silicon substrate with a recess formed therein that provides an environment within which the contact is formed. The contact includes: (1) an adhesion layer deposited on an inner surface of the recess, (2) an amorphous layer, deposited over the adhesion layer within the recess and (3) a central plug, composed of a conductive material, deposited at least partially within the recess, the silicide layer being amorphous to prevent the conductive material from passing through the amorphous silicide layer to contact the adhesion layer thereby to prevent junction leakage.
A method of manufacturing a contact in an integrated circuit, said integrated circuit having a silicon substrate with a recess formed therein, said method comprising the steps of:
