Abstract

The hardware and software for automating measurements and processing spectral characteristics of semiconductor structures using the SF-20 spectrophotometer have been optimized. An electrical interface circuit has been proposed. At the software level, a method of double filtering of measured signals has been implemented. The relative error of the electronic measurement path for optical parameters is less than 0.025%, and the full cycle time for measuring the optical transmission spectrum in the range of 0.19–2.5 μm does not exceed 20 minutes.
