  • Publication number: 20110306207
    Abstract: A method of fabricating metal-bearing structures in an integrated circuit such as metal-polysilicon capacitors using conductive metal compounds. Defects due to organometallic polymers formed during the etch of a hard mask material are minimized by using a process that includes a plasma etch for the hard mask that achieves a predominantly chemical character using a fluorine-based etch chemistry. Using a low-temperature liquid-phase strip of the hard mask photoresist instead of an ash prevents further cross-linking of polymers formed during the plasma etch. Etching the metal-bearing material using a hot fully-concentrated mixture of ammonium hydroxide and hydrogen peroxide allows short etch times that are particularly shortened for tantalum nitride films deposited with a nitrogen concentration of about 30 percent or greater.

    Abstract: The described embodiments of methods of bottom-up metal deposition to fill interconnect and replacement gate structures enable gap-filling of fine features with high aspect ratios without voids and provide metal films with good film quality. In-situ pretreatment of metal film(s) deposited by gas cluster ion beam (GCIB) allows removal of surface impurities and surface oxide to improve adhesion between an underlying layer with the deposited metal film(s). Metal films deposited by photo-induced chemical vapor deposition (PI-CVD) using high energy of low-frequency light source(s) at relatively low temperature exhibit liquid-like nature, which allows the metal films to fill fine feature from bottom up. The post deposition annealing of metal film(s) deposited by PI-CVD densifies the metal film(s) and removes residual gaseous species from the metal film(s). For advanced manufacturing, such bottom-up metal deposition methods address the challenges of gap-filling of fine features with high aspect ratios.

  • Patent number: 7972959
    Abstract: Embodiments of the present invention pertain to methods of forming features on a substrate using a self-aligned double patterning (SADP) process. A conformal layer of non-sacrificial material is formed over features of sacrificial structural material patterned near the optical resolution of a photolithography system using a high-resolution photomask. An anisotropic etch of the non-sacrificial layer leaves non-sacrificial ribs above a substrate. A gapfill layer deposited thereon may be etched or polished back to form alternating fill and non-sacrificial features. No hard mask is needed to form the non-sacrificial ribs, reducing the number of processing steps involved.

    Abstract: Some embodiments include methods of forming charge storage transistor gates and standard FET gates in which common processing is utilized for fabrication of at least some portions of the different types of gates. FET and charge storage transistor gate stacks may be formed. The gate stacks may each include a gate material, an insulative material, and a sacrificial material. The sacrificial material is removed from the FET and charge storage transistor gate stacks. The insulative material of the FET gate stacks is etched through. A conductive material is formed over the FET gate stacks and over the charge storage transistor gate stacks. The conductive material physically contacts the gate material of the FET gate stacks, and is separated from the gate material of the charge storage transistor gate stacks by the insulative material remaining in the charge storage transistor gate stacks. Some embodiments include gate structures.
