A steady trend in improving gamma-ray telescopes is the creation of their 3D sensitive medium, trackers based on silicon position-sensitive detectors. Among them, planar double-sided silicon strip detectors (DSSDs) are planned to be used in space telescopes of international observatories and the Russian HERMES project. The characteristics of prototype DSSDs for the e-ASTROGAM and HERMES telescopes are presented, and critical elements of the detectors are discussed. The reality of creating silicon trackers based on the existing physical background and technologies for the development of silicon detectors existing in Russia is shown.
