  • Patent number: 9515155
    Abstract: E-fuses are used in integrated circuits in order to permit real-time dynamic reprogramming of the circuit after manufacturing. An e-fuse is hereby proposed wherein the metal element adapted to be blown upon passage of a current is not comprised of a silicide layer but is rather a metal layer above which a semiconductor layer is formed. A dielectric layer is then formed on the semiconductor layer, in order to prevent metal silicide from forming over the metal layer. The process of manufacturing the e-fuse can be easily integrated in an HKMG manufacturing flow. In particular, fully silicided metal gates may be manufactured in conjunction with the e-fuse, without jeopardizing the correct functioning of the e-fuse.

  • Patent number: 9478434
    Abstract: A method of removing titanium nitride hardmask is described. The hardmask resides above a low-k dielectric layer prior to removal and the low-k dielectric layer retains a relatively low net dielectric constant after the removal process. The low-k dielectric layer may be part of a dual damascene structure having copper at the bottom of the vias. A non-porous carbon layer is deposited prior to the titanium nitride hardmask removal to protect the low-k dielectric layer and the copper. The titanium nitride hardmask is removed with a gas-phase etch using plasma effluents formed in a remote plasma from a chlorine-containing precursor. Plasma effluents within the remote plasma are flowed into a substrate processing region where the plasma effluents react with the titanium nitride.
