    摘要: Methods for quantitatively measuring the performance of a plasma immersion process are provided herein. In some embodiments, a method of quantitatively measuring the performance of a plasma immersion process, using a first substrate comprising an oxide layer deposited atop a silicon layer, may include subjecting the first substrate to a plasma immersion process in a first plasma immersion chamber to form a doped oxide layer atop the first substrate; and determining a thickness of the doped oxide layer by shining a beam of light upon a reflective surface of the doped oxide layer; detecting reflected beams of light off of the reflective surface of the doped oxide layer; and analyzing the reflected beams of light to determine the thickness of the doped oxide layer on the first substrate.
