The main idea, which is discussed in this article, is the aspects of increasing the reliability of power semiconductors with 80 mm and more diameter semiconductor chip applying the technologies of low-temperature sintering of silicon wafers and molybdenum discs using the silver nanoparticles. In addition, the dependence between the joint weld porosity and cycling capability of an experimental sample is examined, as well as the optimal pressure and temperature range of sintering process is defined.
