Abstract:
Methods and systems for performing spectroscopic measurements of semiconductor structures including ultraviolet, visible, and infrared wavelengths greater than two micrometers are presented herein. A spectroscopic measurement system includes a combined illumination source including a first illumination source that generates ultraviolet, visible, and near infrared wavelengths (wavelengths less than two micrometers) and a second illumination source that generates mid infrared and long infrared wavelengths (wavelengths of two micrometers and greater). Furthermore, the spectroscopic measurement system includes one or more measurement channels spanning the range of illumination wavelengths employed to perform measurements of semiconductor structures. In some embodiments, the one or more measurement channels simultaneously measure the sample throughout the wavelength range. In some other embodiments, the one or more measurement channels sequentially measure the sample throughout the wavelength range.

Claim (Index 1):
A spectroscopic metrology system comprising:\n a combined illumination source including a first illumination source configured to generate a first amount of illumination light including wavelengths less than two micrometers and a second illumination source configured to generate a second amount of illumination light including wavelengths greater than two micrometers; an illumination optics subsystem configured to direct the first and second amounts of illumination light from the combined illumination source to a measurement spot on a surface of a specimen under measurement at one or more angles of incidence, one or more azimuth angles, or a combination thereof; a collection optics subsystem configured to collect an amount of collected light from the measurement spot on the surface of the specimen; at least one detector having a planar, two-dimensional surface sensitive to incident light, wherein the at least one detector includes two or more different surface areas each having different photosensitivity, wherein the two or more different surface areas are aligned with a direction of wavelength dispersion across the surface of the at least one detector, the at least one detector configured to detect the incident light and generate output indicative of the detected incident light; and a computing system configured to generate an estimated value of a parameter of interest of the specimen under measurement based on an analysis of the output of the at least one detector.
