There is provided a method and apparatus for assessing in-situ crystal formation in a test sample. Both optical imaging and X-ray diffraction techniques are utilized, with the results of these processes being combined in such a way as to produce an overall score relating to the aptness of crystalline material for harvesting and subsequent X-ray crystallography.
摘要:
Die Erfindung betrifft eine Einrichtung und ein Verfahren für die Bestimmung von Durchmessern eines Kristalls, der aus einer Schmelze gezogen wird. Es sind hierbei mehrere Videokameras vorgesehen, von denen jede einen eigenen Abschnitt entlang der vertikalen Achse des Kristalls oder in eine Richtung senkrecht hierzu abbildet. Die Bildwinkel der Kameras sind so ausgelegt, daß der abzubildende Gegenstand die gesamte Bildebene - wenigstens in einer Richtung - vollständig ausfüllt. Für Gegenstände mit kleinem Durchmesser - z. B. den Kristallhals - wird eine Kamera mit kleinem Bildwinkel verwendet, während für Gegenstände mit großem Durchmesser - z. B. den Kristall-Body - eine Kamera mit großem Bildwinkel verwendet wird.
摘要:
This invention relates to a system and a method for liquid silicon containment, such as during the casting of high purity silicon used in solar cells or solar modules. The containment apparatus includes a shielding member adapted to prevent breaching molten silicon from contacting structural elements or cooling elements of a casting device, and a volume adapted to hold a quantity of breaching molten silicon with the volume formed by a bottom and one or more sides.

A vapor phase epitaxial apparatus comprises a sealable reaction furnace, a wafer accommodation body which is installed in the reaction furnace to dispose a wafer at a predetermined position, a gas feeding means for feeding raw gas toward the wafer, and a heating means for heating the wafer. An epitaxial film is formed on a surface of the wafer by feeding the raw gas into the reaction furnace in a high-temperature state while heating the wafer via the wafer accommodation body by the heating means in the reaction furnace. The wafer accommodation body comprises a heat flow control unit having a cavity formed for accommodating the wafer, and a heat flow transmission unit which is joined to the heat flow control unit to transfer the heat to the wafer accommodated in the cavity. The contact thermal resistance of the heat flow control unit with the heat flow transfer unit is set to be not lower than 1.0 x 10 m K/W and not greater than 5.0 x 10 m K/W, and the heat flow control unit is formed of a material having the thermal conductivity of not smaller than 0.5 times and not greater than 5 times of the thermal conductivity of the wafer disposed on the heat flow transfer unit.
