摘要:
An apparatus for transferring an upright tray at high speeds that can sense an entrance and discharge of the tray. The apparatus includes a transferring unit with pulleys driven by a driving source to form a transferring path. The pulleys contact a fixing member, which is attached to a lower edge of a substrate and mask fixed to the tray. The apparatus also includes a sensing unit with a sensor installed beneath the transferring path to detect the entrance and discharge of the tray. The apparatus may also include rollers disposed to contact both sides of the upper portion of the tray, and the rollers may be coupled with moveable members encased within rails along the transferring path so that the rollers can translate when a tray passes between two rollers. The rollers along both sides of the tray can be arranged symmetrically or alternately in a zigzag pattern.
摘要:
In a method of controlling an effusion cell in a deposition system, including a crucible, a guiding pathway and an injection nozzle, a guiding pathway and an injection nozzle are heated. The crucible is heated after heating the guiding pathway and the injection nozzle. In addition, in cooling the effusion cell including a crucible, a guiding pathway and an injection nozzle, the crucible is cooled. The guiding pathway and the injection nozzle are cooled after cooling the crucible. This method has an advantage of enhancing uniformity of the organic layer formed on the substrate by preventing the clogging of the injection nozzle by deposition material vaporized in the crucible or splashing.

摘要:
A deposition system and its method of control cancels the influence of noise occurring during measuring of a deposition rate using a noise canceller in order to exactly control the deposition rate, and obtains a film of a desired thickness. The deposition system includes a deposition device. A deposition rate sensor measures a deposition rate of the deposition device. A noise canceller cancels a noise component of the measured deposition rate. A power supply unit adjusts power supplied to the deposition device according to an output of the noise canceller.

摘要:
A device for manufacturing a display device includes a deposition source; a deposition thickness calculator for calculating a deposition thickness of a deposition material deposited on a substrate; and a controller for controlling a power of a heater which heats the deposition source by comparing the deposition thickness calculated with a reference thickness. The controller controls the power of the heater either at least one time for each substrate on which the thin film is to be deposited or at regular intervals while the deposition material is deposited. Influence of measurement noise that is included in a quartz crystal sensor for measuring a deposition speed may be minimized, and distribution of deposition thickness of an organic light emitting material may be reduced, thereby increasing the yield of the deposition process and producing quality display devices.

摘要:
An apparatus for depositing an organic material and a depositing method thereof, wherein a deposition process is performed with respect to a second substrate while transfer and alignment processes are performed with respect to a first substrate in a chamber, so that loss of an organic material wasted in the transfer and alignment processes can be reduced, thereby maximizing material efficiency and minimizing a processing tack time. The apparatus includes a chamber having an interior divided into a first substrate deposition area and a second substrate deposition area, an organic material deposition source transferred to within ones of the first and second substrate deposition areas to spray particles of an organic material onto respective ones of first and second substrates and a first transferring unit to rotate the organic material deposition source in a first direction from one of the first and second substrate deposition areas to an other of the first and second substrate deposition areas.
