ABSTRACT

Raman microprobe techniques are used for the first time as a real-time probe during local direct laser writing and also as an in situ probe after writing. The Stokes–Raman emission observed during pyrolytic deposition of micron-dimension structures of silicon on germanium and vitreous carbon substrates is found to be weaker, more asymmetric, and to peak at a smaller Raman shift than the corresponding spectrum of the same structure similarly probed in situ after deposition. Results of detailed post-deposition Raman analysis of these silicon microstructures are presented and compared to the Raman spectra of oven-heated silicon. Potential applications of these techniques are discussed.
