This paper presents the details of an optimum nickel electroforming process for MEMS applications. Electrochemical deposition of nickel microstructures in thick resist moulds from a standard process using a sulphamate electrlyte gives most of the time poor quality deposits: non uniform, sometimes with pitting and without adherence on the substrate. As in MEMS devices the features to be electroplated are of micron size (which creates a big disproportion in the surface area between the two electrodes involved in the plating bath), an optimisation of the standard electroplating rocess was developed.
