Post-growth annealing of the capacitor structure in oxygen deficient atmosphere exhibits the formation of vacancy type defects in all layers. A significant increase in open volume defects was found in the top and bottom electrode. The changes in the bottom electrode were studied more closely by etching off the top layer.}, year = {2000}, journal = {Materials Research Society Symposium - Proceedings}, volume = {596}, pages = {393-397}, publisher = {Materials Research Society, Warrendale, PA, United States}, issn = {02729172}, note = {cited By 2}, language = {eng}, }
