    摘要: A system for improving substrate critical dimension uniformity is described. The system includes an exposing means for exposing a plurality of mask patterns on a first plurality of substrates at predetermined locations with common splits of focus ({Fj}) and exposure dose ({Ek}) for each of the first plurality of substrates to form a plurality of perturbed wafers. A measuring means is provided for measuring a critical dimension of the plurality of mask patterns at each of the predetermined locations for each of the plurality of perturbed wafers. An averaging means is provided for averaging the critical dimension measured at each of the predetermined locations over the plurality of perturbed wafers to form a perturbed critical dimension map. A second measuring means is provided for measuring a sidewall angle of the plurality of mask patterns at each of the predetermined locations for each of the plurality of perturbed wafers. A second averaging means is provided for averaging the sidewall angle measured at each of the predetermined locations over the plurality of perturbed wafers to form a perturbed sidewall angle map. The perturbed critical dimension map and the perturbed sidewall angle map can then be provided to an exposure tool.

    摘要: A method for improving accuracy of optical critical dimension measurement of a substrate is provided. A process parameter that influences the refractive index and extinction coefficient of a thin film in the substrate is identified. A refractive index and extinction coefficient across a plurality of wavelengths as a function of the process parameter is identified. During the regression modeling of the optical critical dimension measurement, the refractive index and extinction coefficient across the plurality of wavelengths is adjusted through the function via the process parameter.

    摘要: A system for overlay offset measurement in semiconductor manufacturing including a radiation source, a detector, and a calculation unit. The radiation source is operable to irradiate an overlay offset measurement target. The detector is operable to detect a first reflectivity and a second reflectivity of the irradiated overlay offset measurement target. The calculation unit is operable to determine an overlay offset using the detected first and second reflectivity by determining a predetermined overlay offset amount which provides an actual offset of zero.
