Breath Figure-Assisted Fabrication of Nanostructured Coating on Silicon Surface and Evaluation of Its Antireflection Power

Abstract: We report our recent results on the fabrication of nanostructured polymer layers aimed at developing efficient antireflection coating on silicon. The proposed manufacturing approach is based on self-assembly and relies on breath figure formation. By simple and straightforward operations, we are able to produce different nanostructured coatings: densely packed nanodomes, randomly distributed nanopores, and multilayered close-packed nanopores. By optical reflectivity measurements on coated silicon wafers, we sho… Show more

“…Various experimental techniques were successfully applied for breath-figure self-assembly, including drop-casting [ 66 , 67 , 68 , 69 , 70 , 71 ], spin-coating [ 72 , 73 , 74 , 75 , 76 , 77 , 78 ], the “doctor-blade” technique [ 79 , 80 ], and dip-coating [ 46 , 54 , 58 , 81 , 82 , 83 ]. When breath-figures-inspired patterns are formed under drop-casting, a drop of polymer solution is deposited by a precise micro-syringe (or micro-injector) on a solid substrate and exposed to air flow with a controlled humidity [ 66 , 67 , 68 , 69 , 70 , 71 ].…”

“…The substrate is then rotated at high speed in order to spread the evaporated polymer solution by centrifugal force. The whole process is performed under controlled humidity [ 72 , 73 , 74 , 75 , 76 , 77 , 78 ]. In the doctor-blade technique, an immobilized blade applies a unidirectional shear force to the polymer solution that passes through a small gap between the blade and the substrate [ 79 , 80 , 81 ].…”

“…The potentiality of this technology is extensive, especially in terms of production speed: fabricating a colloidal 2DPC takes tenths of minutes to hours; making a pattern by breath figures takes a few seconds to 2-3 min. Thanks to its extreme simplicity and fast realization, the breath figure process has been applied in materials science in a great number of studies and for different applications [64][65][66][67][68][69][70][71]. For nanofabrication purposes, breath figure arrays can also represent the starting structure from which different kinds of patterns can be developed by further fabrication steps such as electrodeposition [72], pyrolysis [73], or dry etching [74].…”
