摘要:
A method and an apparatus for pulling a compound single crystal from a raw material molten solution is constructed to cause the solution to flow into a second crucible provided in a first crucible containing the raw material molten solution which is continuously synthesized from a plurality of raw materials, through a communicating hole formed in the bottom portion of the second crucible. The single crystal is pulled while the raw material molten solution is continuously synthesized from the plurality of raw materials, whereby it is possible to pull a long single compound crystal through a single pulling step from the raw material molten solution which is contained in the second crucible. An excellent state of a solid-liquid interface is maintained to obtain a quality single crystal.

A liquid processing apparatus is provided which can reduce the amount of liquids used and reduce the difference of the process level between objects to-be-processed. The liquid processing apparatus includes a main pipe, a liquid supply device, a main valve, a plurality of branch pipes, and a plurality of processing units. The liquid supply device includes a mixer, a first liquid supply pipe, and a second liquid source supplying a second liquid and supplies a mixed liquid prepared by mixing the first and second liquids in the mixer to one end of the main pipe. The main valve is configured to close the other end of the main pipe opposite to the liquid supply device when the object to-be-processed is processed in the processing unit.

The present invention provides a substrate processing system in which a processing liquid is supplied to a substrate W from a processing nozzle 50a situated above the substrate W so as to process the substrate W, and which makes it possible to prevent unintended dripping of the processing liquid from the processing nozzle. A substrate processing system 20 comprises a processing nozzle 50a capable of supplying a processing liquid to a substrate to be processed, an arm 54 supporting the processing nozzle, and droplet removing nozzles 60, 62 capable of blowing a gas to the processing nozzle. The arm is movable between a processing position and a waiting position, the processing nozzle being above a substrate when the arm is in the waiting position and being outside a substrate when the arm is in the processing position. The droplet removing nozzles are so situated that they are in the vicinity of the processing nozzle when the arm is in the waiting position.
