Inventor: AOKI KATSUHIRO
IPC: H01L21/02
Filed: 1993-04-16
Abstract: PURPOSE:To prepare a ferroelectric thin film having perovskite crystal structure by blending an organometallic compound of a metal element constituting the ferroelectric film with a stabilizer made of alkanol amine and/or beta-diketone in a specific ratio, applying the blended raw material solution, drying and sintering at a relatively low temp. CONSTITUTION:At the time of forming the ferroelectric film by sol-gel method, the raw material solution containing the organometallic compound (e.g. lead fatty acid, titanium alkoxide and zirconium alkoxide) of the metal element constituting the ferroelectric film and the stabilizer made of alkanol amine and/or beta-diketon in the concentration of 10>= (stabilizer/total metallic atom) >=4 by molar ratio of alkanol amine per total metal atom is prepared and is applied and dried. The prepared dried film is oxidized and sintered at 450-700 deg.C to obtained the ferroelectric film (e.g. lead titanate zirconate). By utilizing this method, the oxidation and sintering temp is lowered at the time of forming the ferroelectric film.

Abstract: PURPOSE:To facilitate and shorten a test by providing a domino circuit with the output signal of a micro-ROM as a gate input and fetching its output as a checking signal. CONSTITUTION:When a test, by making a test signal T25 'H', gate signals 1e-1h all become 'H' and all transistors in a ROM 10 and a micro-RM 1 are turned on.

When there are disconnections in the lines of the gate signals 1e-1h, the ROM 10 does not become ON, the check signal C12 become 'H' and an error is shown. When there is a disconnection in a diffusion area, the output signals 3-9 becomes 'H' and an error is shown. When there is a disconnection in a diffusion area, the output signals 3-9 become 'L', in the same way, the check signal C12 becomes 'H' and an error is shown. Thus, by only making the test signal T 'H', the disconnections of the gate or diffusion wiring can be checked instant ly and the test can be facilitated and shortened.
