  • Publication number: 20220352348
    Abstract: Embodiments provide a treatment process to a dielectric layer deposited in a source/drain recess. The treatment process alters the etch selectivity of the horizontal portions of the dielectric layer to cause the etch rate of the horizontal portions of the dielectric layer to have a lower etch rate than the vertical portions of the dielectric layer. The vertical portions are removed by a wet etch process to leave a portion of the dielectric layer at a bottom of the source/drain recess.
