Title: Method of manufacturing ferroelectric capacitor
Inventor: TSUKADA MINEHARU
IPC: C23C16/40
Filed: 2003-01-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a ferroelectric capacitor capable of forming a ferroelectric film and an electrode film continuously in the same chamber.  <P>SOLUTION: Ru material is supplied into an MOCVD chamber together with nitrogen gas. The above state is maintained so as to form an Ru film. Then, the nitrogen gas is reduced to 20 vol.%, and 80 vol.% oxygen gas as reactive gas is started to be supplied. Moreover, Pb material is made to start feeding, and the Ru material is made to stop feeding immediately after the supply of the Pb material is started. As the result, Ru is reduced in volume as Pb increases in volume in the MOCVD chamber. During the above processes, a lower conductive compound film is formed. After the Ru material is made to stop fully introducing into the MOCVD chamber, Ti material and Zr material are made to start supplying as the Pb material is made to keep supplying. The above state is made to maintain so as to form a PZT film. Ru is restrained from diffusing into the PZT film by the lower conductive compound film, and a leakage current is prevented also from increasing by the lower conductive compound film.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for detecting the present location of a target article which has little possibility that a theft performer recognizes or invalidates the method when the article is stolen.  <P>SOLUTION: When an article owner 1 sends a research request for the target article 6 to a communication provider 2, the communication provider 2 periodically transmits a code corresponding to the serial number of the target article 6 to all base stations 3 to 5 and instructs the base stations 3 to 5 not to use an incoming communication channel for this invention for a second use for several mili-seconds after the transmission. A device for the invention built in the target article 6 transmits a prescribed pilot signal only for a very short period of time which is several mili-seconds upon the reception of a code of its own station. When the base station 3 notifies the communication provider 2 of the reception of the pilot signal, the communication provider 2 reports to the owner 1 that the target article 6 exists in the area of the base station 3. Unless the pilot signal is received even though the code is transmitted as many as the prescribed number of times, other communication providers that have introduced a system by the method of the invention are used to search the target article 6.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
