Abstract: A precursor composition is disclosed for use in the chemical vapor deposition of a material selected from the group consisiting of silicon oxynitride, silicon nitride, and silicon oxide. The composition comprises a hydrazinosilane of the formula: [R12N—NH]nSi(R2)4-n where each R1 is independently selected from alkyl groups of C1 to C6; each R2 is independently selected from the group consisting of hydrogen, alkyl, vinyl, allyl, and phenyl; and n=1-4.

Abstract: Classes of liquid aminosilanes have been found which allow for the production of silicon carbo-nitride films of the general formula SixCyNz. These aminosilanes, in contrast, to some of the precursors employed heretofore, are liquid at room temperature and pressure allowing for convenient handling. In addition, the invention relates to a process for producing such films. The classes of compounds are generally represented by the formulas: and mixtures thereof, wherein R and R1 in the formulas represent aliphatic groups typically having from 2 to about 10 carbon atoms, e.g., alkyl, cycloalkyl with R and R1 in formula A also being combinable into a cyclic group, and R2 representing a single bond, (CH2)n, a ring, or SiH2.

Abstract: This invention relates to an improved process for producing ternary metal silicon nitride films by the cyclic deposition of the precursors. The improvement resides in the use of a metal amide and a silicon source having both NH and SiH functionality as the precursors leading to the formation of such metal-SiN films. The precursors are applied sequentially via cyclic deposition onto the surface of a substrate. Exemplary silicon sources are monoalkylamino silanes and hydrazinosilanes represented by the formulas: (R1NH)nSiR2mH4-n-m (n=1,2; m=0,1,2; n+m=<3); and (R32N—NH)xSiR4yH4-x-y (x=1,2; y=0,1,2; x+y=<3) wherein in the above formula R1-4 are same or different and independently selected from the group consisting of alkyl, vinyl, allyl, phenyl, cyclic alkyl, fluoroalkyl, silylalkyls.

Abstract: A process for the plasma enhanced chemical vapor deposition of silicon nitride films from nitrogen, argon, xenon, helium or ammonia and an aminosilane, preferably of the formula: (t-C4H9NH)2SiH2 that provides improved properties, particularly etch resistance and low hydrogen concentrations as well as stress control, of the resulting film for use in the semiconductor industry.

Abstract: Inorganic precursors, namely iodosilane precursors, for the low temperature, low pressure deposition of silicon-containing films is provided therein. In one aspect, there is provided a process for forming a silicon-containing film process comprising: introducing a substrate and gaseous reagents comprising an iodosilane precursor having three or less iodine atoms bound to the silicon atom and at least one reagent selected from an oxygen-containing reactive gas, a nitrogen-containing reactive gas, a hydrogen-containing reactive gas and mixtures thereof into a reaction chamber; heating the reaction chamber to one or more temperatures ranging from 200° C. to 900° C. to form the silicon containing film on the substrate, provided that if the iodosilane precursor has three iodine atoms bound to the silicon atom then the heating step is conducted at one or more pressures less than 600 Torr.

Abstract: Vessel and method for the production and delivery of a precursor-containing fluid stream comprising the gaseous phase of a precursor material are disclosed herein. In one aspect, there is provided an vessel comprising: an interior volume wherein the interior volume is segmented into an upper volume and a lower volume wherein the upper volume and the lower volume are in fluid communication; a lid comprising a fluid inlet, a fluid outlet, an optional fill port, and an internal recess wherein at least a portion of the upper volume resides within the internal recess; a sidewall interposed between the lid and a base; and at least one protrusion that extends into the lower volume wherein the precursor is in contact with the at least one protrusion and wherein at least one protrusion extends from at least one selected from the lid, the sidewall, the base, and combinations thereof.
