Abstract: An advanced back-end-of-line (BEOL) metallization structure is disclosed. The structure includes a bilayer diffusion barrier or cap, where the first cap layer is formed of a dielectric material preferably deposited by a high density plasma chemical vapor deposition (HDP CVD) process, and the second cap layer is formed of a dielectric material preferably deposited by a plasma-enhanced chemical vapor deposition (PE CVD) process. A method for forming the BEOL metallization structure is also disclosed. The invention is particularly useful in interconnect structure comprising low-k dielectric material for the inter-layer dielectric (ILD) and copper for the conductors.

Abstract: In a BEOL process, UV radiation is used in a curing process of ultra low-k (ULK) dielectrics 100. This radiation penetrates through the ULK material and reaches the cap film underneath it. The interaction between the UV light and the film leads to a change the properties of the cap film. Of particular concern is the change in the stress state of the cap from compressive to tensile stress. This leads to a weaker dielectric-cap interface and mechanical failure of the ULK film. A layer of nanoparticles 120 is inserted between the cap 130 and the ULK film. The nanoparticles absorb the UV light before it can damage the cap film, thus maintaining the mechanical integrity of the ULK dielectric.

Abstract: A back end of the line (BEOL) fuse structure having a stack of vias (122, 132). The stacking of vias (122, 132) leads to high aspect ratios making liner and seed coverage inside the vias poorer. The weakness of the liner (124) and seed layers leads to a higher probability of electromigration (EM) failure. The fuse structure addresses failures due to poor liner and seed coverage. Design features permit determining where failures occur, determining the extent of the damaged region after fuse programming and preventing further propagation of the damaged dielectric region.

Abstract: Es wird eine BEOL-E-Sicherung offenbart, die zuverlässig im Durchkontakt durchbrennt und selbst in den BEOL-Schichten mit engsten Abständen gebildet werden kann. Die BEOL-E-Sicherung kann mit einem Line-First-Dual-Damascene-Prozess gebildet werden, um einen sublithografischen Durchkontakt zu ergeben, der das programmierbare Element der E-Sicherung ist. Der sublithografische Durchkontakt kann durch Standard-Lithografie strukturiert werden, und der Querschnitt des Durchkontakts kann dem Sollprogrammierstrom entsprechend abgestimmt werden.

Abstract: Bei einem BEOL-Prozess wird in einem Härtungsprozess von Ultra-low-k(ULK)-Dielektrika 100 UV-Strahlung verwendet. Diese Strahlung durchdringt das ULK-Material und erreicht die darunter liegende Deck-Dünnschicht. Die Wechselwirkung zwischen dem UV-Licht und der Dünnschicht führt zu einer Änderung der Eigenschaften der Deck-Dünnschicht. Von besonderer Bedeutung ist der Übergang des Spannungszustands der Deckschicht von Druckspannung zu Zugspannung. Das führt zu einer schwächeren Grenzfläche zwischen dem Dielektrikum und der Deckschicht und einer mechanischen Schädigung der ULK-Dünnschicht. Zwischen der Deckschicht 130 und der ULK-Dünnschicht wird eine Schicht Nanopartikel 120 eingefügt. Die Nanopartikel absorbieren das UV-Licht, bevor es die Deck-Dünnschicht schädigen kann, sodass die mechanische Stabilität des ULK-Dielektrikums erhalten bleibt.

Abstract: A BEOL e-fuse is disclosed which reliably blows in the via and can be formed even in the tightest pitch BEOL layers. The BEOL e-fuse can be formed utilizing a line first dual damascene process to create a sub-lithographic via to be the programmable link of the e-fuse. The sub-lithographic via can be patterned using standard lithography and the cross section of the via can be tuned to match the target programming current.
