摘要 |
The present invention is a method to increase the intrinsic compressive stress in plasma enhanced chemical vapor deposition (PECVD) silicon nitride (SiN) and silicon carbonitride (SiCN) thin films, comprising depositing the film from an amino vinylsilane-based precursor. More specifically the present invention uses the amino vinylsilane-based precursor selected from the formula: [RR1N]xSiR3y(R2)z, where x+y+z=4, x=1-3, y=0-2, and z=1-3; R, R1 and R3 can be hydrogen, C1 to C10 alkane, alkene, or C4 to C12 aromatic; each R2 is a vinyl, allyl or vinyl-containing functional group. |
