Patent ID: 7924547

Claim:
A structure, comprising: (a) a TiW oxygen plasma mask, the TiW oxygen plasma mask having a mask pattern; (b) a 2000 angstrom thick oxygen plasma vaporizable RuO 0.8 electrode layer partially under and in contact with the TiW oxygen plasma mask, the 2000 angstrom thick oxygen plasma vaporizable RuO 0.8 electrode layer not being completely covered by the mask pattern of the TiW oxygen plasma mask; (c) a PZT ferroelectric layer in contact with the 2000 angstrom thick oxygen plasma vaporizable RuO 0.8 electrode layer; (d) a second RuO 0.8 electrode layer in contact with the PZT ferroelectric layer; and (e) a photoresist mask above and in contact with the TiW oxygen plasma mask, the photoresist mask having a same size mask pattern as the mask pattern of the TiW oxygen plasma mask.
