Title: Ferroelectric body capacitor and its manufacturing method
Inventor: INOMATA DAISUKE
IPC: H01L21/822
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a ferroelectric capacitor with superior hysteresis, residual polarization saturation, fatigue, and anti-reduction characteristics, and its manufacturing method. SOLUTION: A ferroelectric body capacitor 1 is composed of an Si substrate 100, an SiO2 layer 200, an IrO2 layer 10, a Ti layer 20, a Pt layer 30, a PZT(lead zirconate titanate) layer 35, and an IrO2 layer 40. When the Pt layer 30 is formed, heat treatment is made at approximately 350 deg.C for approximately 15 minutes in an electric oven. Due to the heat treatment, Ti for composing the Ti layer 20 is thermally diffused to the surface of the Pt layer 30, namely, a surface where the PZT layer 35 is formed later. The Ti being diffused on the surface of the Pt layer 30 reacts to surplus Pd in the PZT layer 35 for forming lead titanate PbTiO3 with relatively low crystallization temperature.

Filed: 1985-02-13
Abstract: PURPOSE:To enhance painting quality, by interposing a combustion gas generating burner in a hot air recirculation path and directly recirculating and convecting the combustion gas generated from said burner in a drying oven to directly heat said oven. CONSTITUTION:The operation of a drying oven 1 is started and the recirculation fan 9 interposed to a hot air recirculation path N is operated when the oven is preheated to rise in its temp. while a burner 7 is ignited and air in the oven is sucked from a return duct 4 to raise the temp. of the oven to high temp. by the combustion gas of the burner 7 and introduced into the oven from a supply duct 6 along with the combustion gas to be recirculated and convected and the temp. in the oven is rapidly raised by direct heating. When the oven reaches predetermined temp., an operation signal is emitted from a control apparatus 15 to stop the combustion of the burner 7 and the operation of a blower 10. Because hot air is recirculated and convected in the oven to directly heat the oven, the yellowing of the paint film on an article to be painted heated in the oven or the formation of a resinous substance causing the generation of interlayer delamination can be prevented.
