Title: Method of manufacturing silicon epitaxial wafer
Inventor: YOSHIDA CHISA
IPC: H01L21/205
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing silicon epitaxial wafer by which the growing speed of an epitaxial layer can be improved, while the occurrence of slipping dislocation formed on a silicon epitaxial wafer is suppressed. SOLUTION: This method of manufacturing silicon epitaxial wafer includes a step of gradually growing a silicon epitaxial layer on a single-crystal silicon substrate, by gradually increasing the heating power to the silicon substrate and also gradually increasing the feed rate of a gaseous starting material. Since the heating power to the silicon substrate and the feed rate of the gaseous starting material are gradually increased, the feed rate of the gaseous starting material can be increased gradually, while the quantity of heat that is taken by the gaseous starting material from the silicon substrate is supplemented gradually unlike the conventional manufacturing method, in which a large quantity of gaseous starting material suddenly starts to flow.  Consequently, the temperature drop of the silicon substrate hardly occurs, and the occurrence of slipping dislocation can be suppressed effectively.

Title: Detector of optical sensor signal current
Inventor: GEORGE JOHN BARRET
IPC: H04N17/04
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To eliminate mismatching of detection by providing a constitution, where the current supplied from a current source is branched in accordance with a 1st ratio and supplied to a detector to show an illumination off state when no illumination is secured via a trace image, the current is supplied from the current source in accordance with a 2nd ratio with dependence on the illumination intensity defined by the trace image put on a current sink and the detector, where no current is supplied shows an illumination on state. SOLUTION: A reference current Iref is supplied to a photosensitive sensor S1 and a sensor detector 275. When the sensor S1 is not illuminated, the sensor S1 shows a high impedance and branches a slight current Isen out of the current Iref. Most of the current Iref is supplied to the detector 275 as a current Isw. The current Isw biases the detector 275, to set the output state at a low level. This state shows that no light is emitted to the sensor S1, i.e., the sensor S1 is not illuminated. When the sensor S1 is illuminated, the current Isw is branched out of the detector 275.
