Title (EN) PVD ALN FILM WITH OXYGEN DOPING FOR A LOW ETCH RATE HARDMASK FILM
(FR) FILM ALN PVD AVEC DOPAGE D'OXYGÈNE D'UN FILM DE MASQUE DUR À FAIBLE VITESSE DE GRAVURE
Abstract:
(EN) The present invention generally relates to a doped aluminum nitride hardmask and a method of making a doped aluminum nitride hardmask. By adding a small amount of dopant, such as oxygen, when forming the aluminum nitride hardmask, the wet etch rate of the hardmask can be significantly reduced. Additionally, due to the presence of the dopant, the grain size of the hardmask is reduced compared to a non-doped aluminum nitride hardmask. The reduced grain size leads to smoother features in the hardmask which leads to more precise etching of the underlying layer when utilizing the hardmask.
(FR) La présente invention concerne globalement un masque dur en nitrure d'aluminium dopé et un procédé de fabrication d'un masque dur en nitrure d'aluminium dopé. En ajoutant une petite quantité de dopant, comme de l'oxygène, lors de la formation du masque dur en nitrure d'aluminium, on peut significativement diminuer la vitesse de gravure humide du masque dur. De plus, du fait de la présence du dopant, la taille de grain du masque dur est diminuée par rapport à un masque dur en nitrure d'aluminium non dopé. La taille de grain réduite donne des caractéristiques plus lisses du masque dur, ce qui conduit à une gravure plus précise de la couche sous-jacente lors de l'utilisation du masque dur.
