This paper reviews the state-of-the-art of superconducting microstrip single-­photon detectors and provides their comparison with the nanostrip detectors. The article describes the actual detection models required for understanding the SMSPD operating principles. We have analyzed the manufacturing materials of ultrathin films designed for SMSPD demonstrating the prospects for the use of X-ray amorphous materials with α-­Mn structure. As a result of methods study to improve the detector specifications, we have provided the following recommendations: to reduce DCR and increase SDE, CR and active area, it is necessary to use the SMSPDs based on the X-ray amorphous materials with a low diffusion coefficient, a topology with a high filling factor and the strip spreading at the turn based on a DBR structure.
