Abstract

Semiconductor devices and fabrication methods are presented, in which a hydrogen barrier is provided above a ferroelectric capacitor to prevent degradation of the ferroelectric material during back-end manufacturing processes employing hydrogen. The hydrogen barrier comprises silicon rich silicon oxide or amorphous silicon, which can be used in combination with an aluminum oxide layer to inhibit diffusion of process-related hydrogen into the ferroelectric capacitor layer.
