摘要： Methods of forming a dielectric layer are described. The methods include the steps of mixing a silicon-containing precursor with a plasma effluent, and depositing a silicon-and-nitrogen-containing layer on a substrate. The silicon-and-nitrogen-containing layer is converted to a silicon-and-oxygen-containing layer by curing in an ozone-containing atmosphere in the same substrate processing region used for depositing the silicon-and-nitrogen-containing layer. Another silicon-and-nitrogen-containing layer may be deposited on the silicon-and-oxygen-containing layer and the stack of layers may again be cured in ozone all without removing the substrate from the substrate processing region. After an integral multiple of dep-cure cycles, the conversion of the stack of silicon-and-oxygen-containing layers may be annealed at a higher temperature in an oxygen-containing environment.

摘要： A method of forming a silicon oxide layer is described. The method first deposits a silicon-nitrogen-and-hydrogen-containing (polysilazane) film by radical-component chemical vapor deposition (CVD). The silicon-nitrogen-and-hydrogen-containing film is formed by combining a radical precursor (excited in a remote plasma) with an unexcited carbon-free silicon precursor. A capping layer is formed over the silicon-nitrogen-and-hydrogen-containing film to avoid time-evolution of underlying film properties prior to conversion into silicon oxide. The capping layer is formed by combining a radical oxygen precursor (excited in a remote plasma) with an unexcited silicon-and-carbon-containing-precursor. The films are converted to silicon oxide by exposure to oxygen-containing environments. The two films may be deposited within the same substrate processing chamber and may be deposited without breaking vacuum.

摘要： Methods of forming dielectric layers are described. The methods may include forming a silicon-nitrogen-and-hydrogen-containing layer on a substrate. The methods include ozone curing the silicon-nitrogen-and-hydrogen-containing layer to turn the silicon-nitrogen-and-hydrogen-containing layer into a silicon-and-oxygen-containing layer. Following ozone curing, the layer is exposed to an amine-water combination at low temperature before an anneal. The presence of the amine cure allows the conversion to silicon-and-oxygen-containing layer to occur more rapidly and completely at a lower temperature during the anneal. The amine cure also enables the anneal to use a less oxidative environment to effect the conversion to the silicon-and-oxygen-containing layer.

Described are chemical vapor deposition methods of forming films (e.g., silicon-containing films) as photoresists using a plasma which may be exposed to radiation to form a pattern. The deposition methods utilize precursors with cross- linkable moieties that will cross-link upon exposure to radiation. Radiation may be carried out in the with or without the presence of oxygen. Exposed or unexposed areas may then be developed in an aqueous base developer.

摘要： Methods of forming silicon oxide layers are described. The methods include the steps of concurrently combining both a radical precursor and a radical-oxygen precursor with a carbon-free silicon-containing precursor. One of the radical precursor and the silicon-containing precursor contain nitrogen. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain very little nitrogen. The radical-oxygen precursor and the radical precursor may be produced in separate plasmas or the same plasma. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.

摘要： A method of forming a silicon oxide layer is described. The method may include the steps of mixing a carbon-free silicon-containing precursor with a radical-nitrogen precursor, and depositing a silicon-and-nitrogen-containing layer on a substrate. The radical-nitrogen precursor is formed in a plasma by flowing ammonia and nitrogen (N2) and/or hydrogen (H2) into the plasma in order to allow adjustment of the nitrogen/hydrogen ratio. The silicon-and-nitrogen-containing layer may be converted to a silicon-and-oxygen-containing layer by curing and annealing the film.

摘要： A method of etching a recess in a semiconductor substrate is described. The method may include forming a dielectric liner layer in a trench of the substrate where the liner layer has a first density. The method may also include depositing a second dielectric layer at least partially in the trench on the liner layer. The second dielectric layer may initially be flowable following the deposition, and have a second density that is less than the first density of the liner. The method may further include exposing the substrate to a dry etchant, where the etchant removes a portion of the first liner layer and the second dielectric layer to form a recess, where the dry etchant includes a fluorine-containing compound and molecular hydrogen, and where the etch rate ratio for removing the first dielectric liner layer to removing the second dielectric layer is about 1:1.2 to about 1:1.
