Abstract:
The invention provides a process for the production of a multi-layer stack comprising alternating layers of a polymeric material and an inorganic material, the process comprising a first formation process for the formation of a polymeric material layer or an inorganic material layer followed by a second formation process for the formation of the inorganic material layer or the polymeric material layer; wherein the first formation process and the second formation process comprise a hot wire chemical vapour deposition process using a wire at a predetermined wire temperature and a target substrate at a predetermined substrate temperature; wherein when the formation process comprises the formation of the polymeric material layer, the predetermined wire temperature is at maximum 230 °C; and wherein when the formation process comprises formation of the inorganic material layer, the predetermined substrate temperature is at maximum 110 °C. The invention also provides a device with such multi-layer stack.
