B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers a installation for control the temperature fields of microwave monolithic integrated circuits with laser Raman spectroscopy method under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus manufactures installations, designed for temperature fields mapping using confocal microscopy of laser radiation Raman scattering in working semiconductor instrument structures of microwave monolithic integrated circuits (MMIC) with submicron spatial resolution.

The local temperature is determined according to the ratio of intensities of Stokes and anti-Stokes components of the scattered laser radiation, which allows the determination of local temperature without reference to a certain material or ratio of elements in solid solutions. This also allows one to determine local temperatures in LEDs and on the output mirrors of laser diodes.

In the developed installation, the local temperature is determined by the ratio of the intensities of the scattered light components, which makes it possible to exclude the contribution of varying mechanical stresses in the heterostructure resulting from uneven heating to the temperature determined by the spectral shift of the Stokes component (standard method).
