Title: Method of manufacturing semiconductor device
Inventor: WADA YUKIHISA
IPC: H01L21/28
Filed: 2001-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, which comprises an etching process which is unavoidable of the deterioration of an etching selection ratio of each oxide film, when the method of manufacturing the semiconductor device is accompanied by the formation of two kinds of oxide films or more, having etching characteristics different from each other. SOLUTION: The method of manufacturing a semiconductor device is performed by making a stacked film sidewall comprises a first oxide film, such as an NSG film or a TEOS film, and a second oxide film, such as a BPSG film or a PSG film, is formed on the side surface of a gate electrode. After that, after the laminated film sidewall has been used as an injection mask for source and drain formation of a MIS transistor, the sidewall is subjected to wet etching with a water solution containing a hydrofluoric acid and an acetic acid or an isopropyl alcohol, when the second oxide film is selectively removed. Hereby, the etching selection ratio of each oxide film is increased, and only the upper second oxide film is removed.

Title: Fuel cell system
Inventor: MIYAKUBO HIROSHI
IPC: H01M8/00
Filed: 2001-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a fuel cell system capable of detecting leakage of hydrogen during operation, with less detectors. SOLUTION: The hydrogen gas delivered from a tank 4 is measured for pressure and temperature with sensors 14 and 15, and its flow rate is adjusted by a restriction area A of a valve 5, so that it is supplied toward a stack 1 at the sound speed. The waste hydrogen gas in the stack 1 is repeatedly supplied to the stack 1 by a recirculation device 6. When the leakage of the hydrogen gas is detected, the fluctuation in the load amount of a drive motor 23 is canceled with a secondary cell 24, so that the normal operation of the stack 1 is forced. Since the hydrogen gas passes through the valve 5 at the sound speed, the condition of hydrogen gas in the lower stream of the valve 5 is not required to be considered when calculating the mass flow rate of the supplied hydrogen gas.  Whether hydrogen gas is leaking or not is known by comparing the calculated mass flow rate with the mass of the hydrogen gas actually consumed for power generation which is known from the current value of the stack 1.
