In this paper features of formation of the alloyed area of the anode and its influence on the characteristics of a planar high-speed diode are considered. The effect of gold diffusion on the change in the current-voltage characteristic of a diode is studied experimentally. A technological model of a planar high-speed diode is proposed that allows selecting the optimal structure of the cathode and anode regions and taking into account the change in the current-voltage characteristics of the diode after the diffusion of gold.
