Abstract
A method of manufacturing a semiconductor device. The method comprises fabricating a ferroelectric capacitor. The capacitor's fabrication includes forming conductive and ferroelectric material layers on a semiconductor substrate, forming a hardmask layer on the conductive and ferroelectric material layers, forming an organic bottom antireflective coating layer on the hardmask layer, and, patterning the organic bottom antireflective coating layer. Seasoning in a hardmask etching chamber is substantially unaffected by the patterning.
