    摘要: A method of forming a cap layer over a dielectric layer on a substrate including forming a plasma from a process gas including oxygen and tetraethoxysilane, and depositing the cap layer on the dielectric layer, where the cap layer comprises a thickness of about 600 Å or less, and a compressive stress of about 200 MPa or more. Also, a method of forming a cap layer over a dielectric layer on a substrate including forming a process gas by flowing together about 200 mgm to about 8000 mgm of tetraethoxysilane, about 2000 to about 20000 sccm of oxygen (O2), and about 2000 sccm to about 20000 sccm of carrier gas, generating a plasma from the process gas, where one or more RF generators supply about 50 watts to about 100 watts of low frequency RF power to the plasma, and about 100 watts to about 600 watts of high frequency RF power to the plasma, and depositing the cap layer on the dielectric layer.

    摘要: A method for forming sidewall spacers on a gate stack by depositing one or more layers of silicon containing materials using PECVD process(es) on a gate structure to produce a spacer having an overall k value of about 3.0 to about 5.0. The silicon containing materials may be silicon carbide, oxygen doped silicon carbide, nitrogen doped silicon carbide, carbon doped silicon nitride, nitrogen doped silicon oxycarbide, or combinations thereof. The deposition is performed in a plasma enhanced chemical vapor deposition chamber and the deposition temperature is less than 450° C. The sidewall spacers so produced provide good capacity resistance, as well as excellent structural stability and hermeticity.
