Abstract. The possibility of applying a protective antireflective coating on semiconductor heterostructure surface in the UVА range is examined. It is shown that a specially prepared solution based on standard epoxy-54 EC makes it possible to obtain layers without a significant change in the volume (less than 1 %), as well as reduce losses of radiation generated by the semiconductor structure by 11 %.
