Abstract
A technique comprising: producing an unencapsulated stack of layers defining one or more electronic devices including an organic semiconductor element; and then subjecting the unencapsulated stack of layers to a water removal treatment in a vacuum oven in the presence of an external water adsorbent; wherein the water removal treatment comprises heating the unencapsulated stack of layers in the vacuum oven for a time period longer than a control time period at which a spike in oven pressure attributable to the release of water from the stack of layers would occur with heating under the same treatment conditions but without the water absorbing material.
