A digital computer automatically converts an input representation of a pattern of flip-chip integrated circuit interconnect bumps in a format suitable for a circuit design program into an output representation in a format suitable for a package design program. The system includes legal and technical control features to restrict access and use of private information over a network, such as the Internet. In some embodiments, the SNPs or RSNPs form conversion layers without a host matrix. To this end, a second row with additional electro-optical converters is provided which is configured to convert a second light wavelength that is different from the first light wavelength. The electrolyte includes a ring compound to which metal cations of an oxidation-reduction derivative are bound, so that the anions of the oxidation-reduction derivative can freely deliver electrons, thereby significantly improving the photoelectric conversion efficiency of the solar cells. The method includes directing light to the substrate during polishing of the substrate, receiving reflected light from the substrate, measuring an intensity of the reflected light at each wavelength, and producing a spectrum indicating a relationship between intensity and wavelength from measured values of the intensity.
