Patent number: 7017430Abstract: After placing a sample in a heating vacuum chamber, a probe is climbed down to a position above a capacitor formed in the sample whose electrical characteristic is supposed to be measured. The probe is contacted with both electrodes of the capacitor, which is confirmed by electrical measurement. In order to measure capacitance loss, after filling N2 gas up in the heating vacuum chamber, a mixed gas is introduced from a line for 3 vol % H2+97 vol % N2 to the inside of the heating vacuum chamber. After pressure has been stabilized there, capacitance loss and lapsed time are measured at the same time. Concentrations of residual H2O and residual O2 in the heating vacuum chamber are measured by a quadrupole mass spectrometer QMS; and at the same time, concentrations of each of residual H2O and residual O2 in an exhaust gas are measured by sensors.Type: GrantFiled: May 15, 2003Date of Patent: March 28, 2006Assignee: Fujitsu LimitedInventors: Jeffrey S.

Patent number: 6674633Abstract: A method for the fabrication of a cap layer on a top electrode layer of a ferroelectric capacitor includes the steps of depositing an amorphous layer, usually made of Sr(x)Ru(y)O3, on the top electrode and then annealing the amorphous layer in two stages in order convert the amorphous layer into the cap layer. The first anneal is performed at 500° C. to 700° C. in a non-oxidizing atmosphere, such as nitrogen, and converts the amorphous layer into a crystallized layer of Sr(x)Ru(y)O3. The second anneal is performed at 300° C. to 500° C. in an oxidizing atmosphere, such as oxygen, and converts the crystallized layer into the cap layer. The method is applied to the formation of a ferroelectric capacitor element of an integrated semiconductor device.Type: GrantFiled: February 28, 2001Date of Patent: January 6, 2004Assignee: Fujitsu LimitedInventors: Shan Sun, George Hickert, Katsuyoshi Matsuura, Takeyasu Saito, Soichiro Ozawa, Naoyuki Satoh, Mitsushi Fujiki, Satoru Mihara, Jeffrey S.
