摘要:
A connection element in an integrated circuit having a layer structure disposed between two conductive structures. The layer structure is formed by an insulating layer, which can be destroyed by application of a predetermined voltage, and a silicon layer. The insulating layer adjoins a first conductive structure made of tungsten.
摘要:
An integrated circuit is formed by a method having the steps of providing a circuit substrate with a first metallized region, providing a first insulation layer covered by a silicon layer, patterning the first insulation layer and silicon layer to form a first insulation region and first silicon region, then forming a second metallized layer on the silicon region, heating the material so that the second metal layer diffuses into the silicon layer to form a metal silicide region, which is subsequently covered by a second insulating layer having a contact with an interconnect to enable contacting an antifuse formed by the metal silicide region.
摘要:
A dielectric antifuse structure is fabricated in an integrated circuit. The antifuse structure is incorporated in a contact hole in an oxide layer and has a dielectric layer arranged between a first conductive layer and a second conductive layer.
