Abstract
A chip-on-board electronic device includes an electronic device die affixed to a printed circuit board, and electrically interconnected thereto by wirebonds. The electronic device is protected by coating it with a layer of silicon oxynitride and, optionally, an overlying thin layer of a conformal coating such as parylene. Under some circumstances, a protective layer of an organic material may be used instead of the layer of silicon oxynitride. The chip-on-board electronic device may be protected with an overlying layer of the conformal coating.
