Raman spectroscopy for thermal characterization of semiconductor devices

Research output: Contribution to journalConference articlepeer-review

Abstract

Raman spectroscopy was used to measure the temperature of semiconductor test structures. The structures consist of molybdenum microwires on a Si (100) substrate buried under a 270nm layer of aluminum nitride. The temperature-dependent Raman spectra of the examined materials were measured in a temperature range from 30 °C to 450 °C using a scientific grade temperature stage for calibration. The relationship between the structure’s temperature and its Raman peak position was modeled. This model was used to estimate the temperature distribution across the test structure at different operating powers with high spatial and temperature resolution.
