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 Al 2 O 3 , and oxidising the Ti layer to form a TiO 2 layer 7. Subsequently, a layer of PZT 9 is formed over the TiO 2 layer 7. The PZT layer 9 is subjected to an annealing step in which, due to the presence of the TiO 2 layer 7 it crystallises to form a layer 11 with a high degree of (111)-texture.
