Thermal Load Influence during the Formation of Al-Al Contacts on the Electrical Parameters of the Integrated Circuits with Aluminum-Polysilicon Contacts by V. A. Pilipenko, V. A. Solodukha, N. S. Kovalchuk, J. A. Solovjov, D. V. Shestovski, D. V. Zhyhulin

“…An analysis of the currentvoltage characteristics showed that they are all identical, except for the course of the direct branch of the base current value from the emitter-base voltage. The deviation of the linear nature of this dependence in the region of their low voltage values (£ 200 mV) in the case of the formation of ohmic Al-Si and Al-Al contacts with the use of long-term heat treatments is due to the predominance of the generation-recombination current in this region associated with an increased density of traps in the depleted region and on the surface of the semiconductor. …”
