Abstract

Disclosed is an etching fluid for electronic devices, comprising: a transition metal and/or a transition metal salt; and a hydrofluoric acid and/or a fluoride salt. The etchant selectively etches an intrinsic semiconductor layer, in an electronic device which has a doped semiconductor layer situated between metal electrodes and said intrinsic semiconductor layer.
