The dielectric function spectra of low dielectric constant (low-k) materials have been determined using high-precision four-zone null spectroscopic ellipsometry, near-normal incidence reflection spectrometry and Fourier transform infrared transmission spectroscopy. The optical functions over a wide spectral range from 0.03t o 5.4 eV (230 nm to 40.5 µm wavelength region) have been evaluated for representative low-k materials used in the semiconductor industry for inter-layer dielectrics: (1) FLARE – organic spin-on polymer, and (2) HOSP – spin-on hybrid organic-siloxane polymer from the Honeywell Electronic Materials Company.
