An additive free electrolyte containing aurochloric acid, sodium sulphite and sodium thiosulphate has been used to electrodeposit gold. The electrolyte is stable at near neutral conditions and was stable on storage after formulation. Laboratory scale experiments showed that the electrolyte was compatible with positive photoresists. UV-Vis spectroscopy and cyclic voltammetry indicate that gold is discharged from a thiosulphate ligand. Industrial scale piloting experiments showed that high quality gold could be deposited from the electrolyte.
