Patent number: 6483137Abstract: A ferroelectric Pb5Ge3O11 (PGO) thin film is provided with a metal organic vapor deposition (MOCVD) process and RTP (Rapid Thermal Process) annealing techniques. The PGO film is substantially crystallization with c-axis orientation at temperature between 450 and 650° C. The PGO film has an average grain size of about 0.5 microns, with a deviation in grain size uniformity of less than 10%. Good ferroelectric properties are-obtained for a 150 nm thick film with Ir electrodes. The films also show fatigue-free characteristics: no fatigue was observed up to 1×109 switching cycles. The leakage currents increase with increasing applied voltage, and are about 3.6×10−7 A/cm2 at 100 kV/cm. The dielectric constant shows a behavior similar to most ferroelectric materials, with a maximum dielectric constant of about 45. These high quality MOCVD Pb5Ge3O11 films can be used for high density single transistor ferroelectric memory applications because of the homogeneity of the PGO film grain size.Type: GrantFiled: August 29, 2001Date of Patent: November 19, 2002Inventors: Tingkai Li, Fengyan Zhang, Yoshi Ono, Sheng Tang Hsu

Patent number: 5423814Abstract: A bipolar coagulation device suitable for use in endoscopic surgery is disclosed which reduces the adhesion of tissue to the electrodes and enables the user to clean the electrodes during the procedure without removal from the body. Bipolar electrocautery forceps are located at the distal end of a sheath suitable for use in endoscopic surgery. The tips of the forceps are manipulated using controls located at the control end of the sheath which remains outside the patient's body. The tips of the forceps are made of material having phosphorous in combination with metals of high thermal conductivity, which reduces the adhesion of tissue during cauterization. In addition, the device has a cleaner which acts to free the forceps of any adhering debris. This cleaning can be done inside the patient's body, without the need for any additional instrumentation. In a preferred embodiment, the tips of the bipolar coagulation device can also be pivoted to an angularly disposed position.Type: GrantFiled: May 25, 1993Date of Patent: June 13, 1995Assignee: Loma Linda University Medical CenterInventors: Yong H.
