Abstract:
A method for forming a dielectric layer on a semiconductor substrate comprising:placing the semiconductor substrate into a chemical vapor deposition chamber; flowing a metal-organic precursor into the chemical vapor deposition chamber, wherein the metal-organic precursor includes a moiety having a first metal atom, an oxygen atom, and a nitrogen atom said metal-organic precursor is characterized as an M(OCR3)xâˆ’yâˆ’z(ONR2)y(OSiR3)z molecule wherein M includes a metal atom selected from a group consisting of aluminum, yttrium, lanthanum, titanium, zirconium, hafnium, niobium, and tantalum and where x is an integer from 3 to 5, y is an integer between 1 and xâˆ’1, z is an integer from 0 to xâˆ’1 and (y+z) is less than or equal to x, wherein the oxygen is chemically bonded to the first metal atom and the nitrogen atom; and forming the dielectric layer on the semiconductor substrate.
