In liquid delivery formulations, the precursors described herein may be delivered in neat liquid form, or alternatively, may be employed in solvent formulations or compositions comprising same.

The method used to form the films or coatings described herein are flowable chemical deposition processes. Electronic books The e-book database EBC. A method for depositing a silicon-containing film, the method comprising: To prevent voiding formation, cross-linking is needed during the treatment.

For example, when diacetoxydimethylsilane is heated, an acetic anhydride molecule is lost and Si—O—Si bonds are formed.

The respective step of supplying the compounds and other reagents may be performed by varying the duration of the time for supplying them to change the stoichiometric composition of the resulting silicon-containing film.

The compositions can be pre-mixed compositions, pre-mixtures mixed before being used in the deposition processor in-situ mixtures mixed during the deposition process. A SumoBrain Solutions Company. The embodiments and features of the present invention can be used alone or in combinations with each other. In this experiment, the process conditions used to deposit flowable porous low-k cdv with the most favorable film properties are as flowablf In this way, a material which contains Si, N and H is deposited onto the wafer and fills the trench.
