A method of forming an implantable electrode having electrode contacts on an electrode carrier having a coating includes providing a solution of silicone and dexamethasone dissolved in a solvent, applying the solution to the electrode carrier or to a substrate, and subjecting the solution to a two-step heat treatment process that includes a first heat treatment between about 50 and 90°C for about 1 to 3 hours and a second heat treatment at an elevated temperature between 90°C and 140°C for about 2 hours in order to form the coating.
