Abstract

There is provided a process for forming a layer of electroactive material having a substantially flat profile. The process includes: providing a workpiece having at least one active area; depositing a liquid composition including the electroactive material onto the workpiece in the active area, to form a wet layer; treating the wet layer on the workpiece at a controlled temperature in the range of −25 to 80° C. and under a vacuum in the range of 10−6 to 1,000 Torr, for a first period of 1-100 minutes, to form a partially dried layer; heating the partially dried layer to a temperature above 100° C. for a second period of 1-50 minutes to form a dried layer.
