Abstract
An electronic device includes a first electrode, a second electrode and an insulating layer between the first and second electrodes, which insulating layer may be susceptible to reduction by H. A gettering layer is provided on and in contact with the first electrode, the gettering layer acting as a protective layer for substantially avoiding reduction of the insulating layer by capturing and immobilizing H. A glue layer may be provided between the gettering layer and first electrode. An additional gettering layer may be provided on and in contact with the second electrode, and a glue layer may be provided between the second electrode and additional gettering layer.
