An impact absorbing, modular helmet that prevents or reduces injury to the user and other parties in a collision is described. The substrate may include a cavity configured to mount the semiconductor light emitting device therein. At least between the source region and the gate electrode and between the drain region and the gate electrode, there is an oxide-nitride-oxide layer sequence. A second conductive layer is then fabricated over the organic layer such that the second conductive layer is in electrical contact with the first conductive layer during at least a portion of the step of depositing the second conductive layer.
