AFM studies of the initial stages of spin-coated prepolymer film growth on silicon wafers

Polymeric film growth on inorganic substrates plays an important role in the technology of sensors and microelectronics. A study of the film growth of a prepolymer of the dicyanate of bisphenol A (DCBA) spin‐coated onto silicon substrates is presented in which layer‐by‐layer growth is demonstrated. This mode of growth is thought to be related to an enrichment of the trimer (see Figure) including a triazine ring.
