Process for fabrication of a ferroelectric capacitor
摘要:
A process for the fabrication of a ferroelectric capacitor comprising depositing a layer of Ti 5 over an insulating layer 3 of Al2O3, and oxidising the Ti layer to form a TiO2 layer 7. Subsequently, a layer of PZT 9 is formed over the TiO2 layer 7. The PZT layer 9 is subjected to an annealing step in which, due to the presence of the TiO2 layer 7 it crystallises to form a layer 11 with a high degree of (111)-texture.
