FIELD: microelectronics. SUBSTANCE: method involves coating metallized integrated circuit surface with layer of silicon dioxide by plasma-chemical method followed by application of film-forming alcohol solution of tetraethoxysilane, annealing at 100-150 C while heating on substrate side to form planarizing layer of silicon dioxide, plasma-chemical etching of this layer, applying second layer of silicon dioxide; novelty is that film-forming solution is applied at substrate temperature of 40-60 C and annealing is carried out while heating at a rate of 0.2-0.3 c/min. EFFECT: improved planarization quality due to eliminating cracks and exfoliation of silicon dioxide layers.
