  • The investigation of the substrate layer influence on the high-frequency parameters of silicon transistors

    In the present paper we propose a modified approximation of a silicon bipolar transistor, which takes into account the frequency relationship of electromagnetic signals propagation in the substrate. These modifications were implemented because the experimental investigations and crosstalk simulations in the metallization layers of a silicon substrate have showed that the commonly used approximations based on lumped elements are not able to describe properly the mutual influence of signals at gigahertz frequencies. It was shown that the proposed method is suitable for high-frequency analog circuits design and it is based on sparse distribution of circuit elements and additional shielding of high-frequency chains. The reproducibility and stability of the circuit’s parameters is achieved by secondary devices which are added for correction and stabilization.

    Keywords: heterostructure bipolar transistors, silicon-germanium base layer, ionizing radiation, simulation of analog cells using substrate influence effect, analog cells parameters stabilization and correction.

    Lean manufacturing of the most of Russian enterprises has a number of characteristics. Firstly, Russian companies are aiming for a prompt effect from the implementation of Lean manufacturing tools, which would neither bring fundamental changes to the situation of the enterprise nor require changes at the company`s senior management level. Secondly, companies are ready to invest significant resources in technology and equipment, which, according to the senior management, can make a considerable breakthrough, while the continuous and gradual improvement is a long process with uncertain economic effect. Thirdly, Russian industrial companies rush to implement Lean manufacturing tools and underestimate the importance of Lean manufacturing philosophy.
