    Abstract: Easily removable heteroatom-doped carbon-containing layers are deposited. The carbon-containing layers may be used as hardmasks. The heteroatom-doped carbon-containing hardmasks have high etch selectivity and density and also a low compressive stress, which will reduce or eliminate problems with wafer bow. Heteroatoms incorporated into the hardmask include sulfur, phosphorous, nitrogen, oxygen, and fluorine, all of which have low reactivity towards commonly used etchants. When sulfur is used as the heteroatom, the hardmask is easily removed, which simplifies the fabrication of NAND devices, DRAM devices, and other devices.

    Abstract: Methods are described for forming a dielectric layer on a patterned substrate. The methods may include combining a silicon-and-carbon-containing precursor and a radical oxygen precursor in a plasma free substrate processing region within a chemical vapor deposition chamber. The silicon-and-carbon-containing precursor and the radical oxygen precursor react to deposit a flowable silicon-carbon-oxygen layer on the patterned substrate. The resulting film possesses a low wet etch rate ratio relative to thermal silicon oxide and other standard dielectrics.

    Abstract: A method of forming and controlling air gaps between adjacent raised features on a substrate includes forming a silicon-containing film in a bottom region between the adjacent raised features using a flowable deposition process. The method also includes forming carbon-containing material on top of the silicon-containing film and forming a second film over the carbon-containing material using a flowable deposition process. The second film fills an upper region between the adjacent raised features. The method also includes curing the materials at an elevated temperature for a period of time to form the air gaps between the adjacent raised features. The thickness and number layers of films can be used to control the thickness, vertical position and number of air gaps.

    Abstract: Methods of depositing initially flowable dielectric films on substrates are described. The methods include introducing silicon-containing precursor to a deposition chamber that contains the substrate. The methods further include generating at least one excited precursor, such as radical nitrogen or oxygen precursor, with a remote plasma system located outside the deposition chamber. The excited precursor is also introduced to the deposition chamber, where it reacts with the silicon-containing precursor in a reaction zone deposits the initially flowable film on the substrate. The flowable film may be treated in, for example, a steam environment to form a silicon oxide film.
