Methods for producing halosilazane comprise halogenating a hydrosilazane with a halogenating agent to produce the halosilazane, the halosilazane having a formula(SiH(NR)X)N(SiHX),wherein each a, b, c is independently 0 to 3; a+b+c=3; d is 0 to 2 and n&#x2265;1; wherein X is selected from a halogen atom selected from F, Cl, Br or I; each R is selected from H, a C-Clinear or branched, saturated or unsaturated hydrocarbyl group, or a silyl group [SiR']; further wherein each R&#x2032; of the [SiR&#x2032;] is independently selected from H, a halogen atom selected from F, Cl, Br or I, a C-Csaturated or unsaturated hydrocarbyl group, a C-Csaturated or unsaturated alkoxy group, or an amino group [&#x2014;NRR] with each Rand Rbeing further selected from H or a C-Clinear or branched, saturated or unsaturated hydrocarbyl group, provided that when c=0, d&#x2260;0; or d=0, c&#x2260;0.

Si-containing film forming precursors and methods of using the same

A Si-containing film forming composition comprising a catalyst and/or a polysilane and a N&#x2014;H free, C-free, and Si-rich perhydropolysilazane having a molecular weight ranging from approximately 332 dalton to approximately 100,000 dalton and comprising N&#x2014;H free repeating units having the formula [&#x2014;N(SiH3)x(SiH2-)y], wherein x=0, 1, or 2 and y=0, 1, or 2 with x+y=2; and x=0, 1 or 2 and y=1, 2, or 3 with x+y=3. Also disclosed are synthesis methods and applications for using the same.

Perhydropolysilazane compositions and methods for forming oxide films using same

Solid or liquid N&#x2014;H free, C-free, and Si-rich perhydropolysilazane compositions comprising units having the following formula [&#x2014;N(SiH)(SiH&#x2014;)], wherein x=0, 1, or 2 and y=0, 1, or 2 when x+y=2; and x=0, 1 or 2 and y=1, 2, or 3 when x+y=3 are disclosed. Also disclosed are synthesis methods and applications for the same.

N&#x2014;H free and Si-rich per-hydridopolysilzane compositions, their synthesis, and applications

Methods for halogenation of a hydrosilazane include contacting the hydrosilazane with a halogenating agent in a liquid phase to produce the halosilazane having a formula(SiH(NR)X)N(SiHX),wherein each a, b, c is independently 0 to 3; a+b+c=3; d is 0 to 2 and n&#x2265;1; wherein X is selected from a halogen atom selected from F, Cl, Br or I; each R is selected from H, a C-Clinear or branched, saturated or unsaturated hydrocarbyl group, or a silyl group [SiR']; further wherein each R&#x2032; of the [SiR&#x2032;] is independently selected from H, a halogen atom selected from F, Cl, Br or I, a C-Csaturated or unsaturated hydrocarbyl group, a C-Csaturated or unsaturated alkoxy group, or an amino group [&#x2014;NRR] with each Rand Rbeing further selected from H or a C-Clinear or branched, saturated or unsaturated hydrocarbyl group.
