    Abstract: Methods of filling gaps with tungsten are described. The methods include a tungsten dep-etch-dep sequence to enhance gapfilling yet avoid difficulty in restarting deposition after the intervening etch. The first tungsten deposition may have a nucleation layer or seeding layer to assist growth of the first tungsten deposition. Restarting deposition with a less-than-conductive nucleation layer would impact function of an integrated circuit, and therefore avoiding tungsten “poisoning” during the etch is desirable. The etching step may be performed using a plasma to excite a halogen-containing precursor while the substrate at relatively low temperature (near room temperature or less). The plasma may be local or remote. Another method may be used in combination or separately and involves the introduction of a source of oxygen into the plasma in combination with the halogen-containing precursor.

    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: A method of etching exposed silicon-and-nitrogen-containing material on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and an oxygen-containing precursor. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents react with the exposed regions of silicon-and-nitrogen-containing material. The plasmas effluents react with the patterned heterogeneous structures to selectively remove silicon-and-nitrogen-containing material from the exposed silicon-and-nitrogen-containing material regions while very slowly removing other exposed materials. The silicon-and-nitrogen-containing material selectivity results partly from the presence of an ion suppression element positioned between the remote plasma and the substrate processing region. The ion suppression element reduces or substantially eliminates the number of ionically-charged species that reach the substrate. The methods may be used to selectively remove silicon-and-nitrogen-containing material at more than twenty times the rate of silicon oxide.

    Abstract: A method of suppressing the etch rate for exposed silicon-and-nitrogen-containing material on patterned heterogeneous structures is described and includes a two stage remote plasma etch. The etch selectivity of silicon relative to silicon nitride and other silicon-and-nitrogen-containing material is increased using the method. The first stage of the remote plasma etch reacts plasma effluents with the patterned heterogeneous structures to form protective solid by-product on the silicon-and-nitrogen-containing material. The plasma effluents of the first stage are formed from a remote plasma of a combination of precursors, including nitrogen trifluoride and hydrogen (H2). The second stage of the remote plasma etch also reacts plasma effluents with the patterned heterogeneous structures to selectively remove material which lacks the protective solid by-product. The plasma effluents of the second stage are formed from a remote plasma of a fluorine-containing precursor.
