    摘要: An analytical furnace includes a predictive temperature control which is trained to model crucible temperature during analysis by employing a pair of temperature sensors, with one sensor being mounted in the furnace in fixed relationship and a second sensor which can be positioned within a crucible for training and tuning a crucible temperature profile, such that the crucible temperature in which a sample is placed is modeled and its response to the application of energy to the furnace in accordance with the furnace's dynamic thermal characteristics is known. By modeling the temperature profile within a crucible, the furnace can be controlled to provide a faster, more accurate analysis and prevent excessive overshooting of temperature as desired temperature plateaus are approached.

    摘要: In the CZ process using a cooling member surrounding a single crystal, the cooling member is permitted to effectively serve to increase a pulling speed. Cracks of the single crystal due to excessive cooling are prevented to occur. A high crystal quality is acquired. In order to realize these objects, the temperature of the inner peripheral surface of the cooling member 6 opposing to the outer peripheral surface of the single crystal 4 is restricted to 500null C. or below, even in the lower end, the temperature of which becomes the highest. To achieve this restriction, the thickness T of the cooling member 5 is 10 to 50 mm. The height H of the cooling member 6 is 0.1 to 1.5 times the diameter D of the single crystal 4.

    摘要: A rotational directional solidification crystal growth system includes a vertical furnace, a crucible, and a rotate support device. The vertical furnace contains a high-temperature portion and a low-temperature portion. The crucible has a seed well and a growth region. The seed well and the growth region contain a seed crystal and raw material, respectively. The crucible moves from the high-temperature portion of the furnace to the low-temperature portion of the furnace or the thermal profile moves related to a stationary crucible to proceed the crystal growth. The rotation support device supports and rotates the crucible, and the tangent velocity of the rotated crucible is no less than about 5null/3 cm/s.

    摘要: A fluid sealing system is provided for use in a crystal puller for growing a monocrystalline ingot. The crystal puller has a housing, a fluid flow path contained in the housing, and a fluid passage through a wall of the housing for passage of fluid. The fluid sealing system includes a fluid connector head adapted for connection to the fluid passage and to the fluid flow path to establish fluid communication between the fluid flow path and the outside of the housing. The head has a port adapted for fluid communication with the fluid passage through the wall of the housing. First and second seals around the port are adapted for sealing engagement with the head. A space is defined generally between the first and second seals, and a leak detector is arranged to monitor the space for detecting fluid leakage past at least one of the seals.

    摘要: At least one amorphous silicon island is formed on a substrate first. A first step and a second step laser crystallization processes are thereafter performed in sequence. The amorphous silicon island is irradiated with a laser pulse having a first energy density to re-crystallize an edge portion of the amorphous silicon island into a polysilicon structure. The amorphous silicon island is then irradiated with a laser pulse having a second energy density to re-crystallize a center portion of the amorphous silicon island into a polysilicon structure.
