    Abstract: A process for the fabrication of a ferroelectric capacitor comprising depositing a layer of Ti (5) over an insulating layer (3) of AI 2 0 3 , and oxidising the Ti layer to form a Ti0 2 layer (7). Subsequently, a layer of PZT (9) is formed over the Ti0 2 layer (7). The PZT layer (9) is subjected to an annealing step in which, due to the presence of the Ti0 2 layer (7) it crystallises to form a layer (11) with a high degree of (111)-texture.
