  • Publication number: 20130323435
    Abstract: Described herein are precursors and methods for forming silicon-containing films. In one aspect, there is provided a precursor of Formula I: wherein R1 is selected from linear or branched C3 to C10 alkyl group, linear or branched C3 to C10 alkenyl group, linear or branched C3 to C10 alkynyl group, C1 to C6 dialkylamino group, electron withdrawing group, and C6 to C10 aryl group; R2 is selected from hydrogen, linear or branched C1 to C10 alkyl group, linear or branched C3 to C6 alkenyl group, linear or branched C3 to C6 alkynyl group, C1 to C6 dialkylamino group, C6 to C10 aryl group, linear or branched C1 to C6 fluorinated alkyl group, electron withdrawing group, and C4 to C10 aryl group; optionally wherein R1 and R2 are linked together to form ring selected from substituted or unsubstituted aromatic ring or substituted or unsubstituted aliphatic ring; and n=1 or 2.

  • Publication number: 20130319290
    Abstract: Described herein are precursors and methods for forming silicon-containing films. In one aspect, there is a precursor of following Formula I: wherein R1 and R3 are independently selected from linear or branched C3 to C10 alkyl group, a linear or branched C3 to C10 alkenyl group, a linear or branched C3 to C10 alkynyl group, a C1 to C6 dialkylamino group, an electron withdrawing and a C6 to C10 aryl group; R2 and R4 are independently selected from hydrogen, a linear or branched C3 to C10 alkyl group, a linear or branched C3 to C10 alkenyl group, a linear or branched C3 to C10 alkynyl group, a C1 to C6 dialkylamino group, an electron withdrawing, and a C6 to C10 aryl group; and wherein any one, all, or none of R1 and R2, R3 and R4, R1 and R3, or R2 and R4 are linked to form a ring.

  • Publication number: 20130129940
    Abstract: Described herein are organoaminosilane precursors which can be used to deposit silicon containing films which contain silicon and methods for making these precursors. Also disclosed herein are deposition methods for making silicon-containing films or silicon containing films using the organoaminosilane precursors described herein. Also disclosed herein are the vessels that comprise the organoaminosilane precursors or a composition thereof that can be used, for example, to deliver the precursor to a reactor in order to deposit a silicon-containing film.
