Title:
METHOD FOR FORMATION OF DIELECTRIC FILM, NOVEL PRECURSOR, AND THEIR USE IN SEMICONDUCTOR PRODUCTION
Document Type and Number:
Japanese Patent JP2014039045
Kind Code:
A
Abstract:

To provide a method for depositing a film of metal-containing dielectric expressed by the formula (I):(Zr1-aM2a)ObNc (where "a" and "b" satisfy 0≤a<1 and 0<b≤3 and preferably 1.5≤b≤2.5 and 0≤c≤1; and M2 represents a metal atom.).

A method for depositing a metal-containing dielectric film comprises: the step a) of loading a substrate into a reaction chamber; the step b) of evaporating a Zr metal-containing precursor selected from a group consisting of Zr(MeCp)(NMe2)3, Zr(EtCp)(NMe2)3, ZrCp(NMe2)3, Zr(MeCp)(NEtMe)3, Zr(EtCp)(NEtMe)3, ZrCp(NEtMe)3, Zr(MeCp)(NEt2)3, Zr(EtCp)(NEt2)3, ZrCp(NEt2)3, Zr(iPr2Cp)(NMe2)3, and Zr(tBu2Cp)(NMe2)3; and the step of depositing, on the substrate, a metal-containing dielectric film including a compound of the formula (I) by use of the first gas-phase-metal source and the appropriate second gas-phase-metal source.
