Thus, the upper plate 220 may be movable on the plate rails 213 in the first direction D1.
Since the upper plate 220 is located on the lower plate 210, the upper plate 220 may be movable in the third direction D3 by the third motor 210m connected to the lower plate 210. The upper plate 220 may be movable in the first and third directions D1 and D3 by the third and fourth motors 210m and 220m.

For example, the magazine MZ before performing the semiconductor package process may be located in the first stage 30a. The magazine MZ after performing the semiconductor package process may be located in the second stage 30b. In other words, the magazine MZ located in the first stage 30a may include substrates. The magazine MZ located in the second stage 30b may be an empty magazine MZ not including substrates.
The stage 30 may include a first region R1, a second region R2 and a third region R3 which are arranged in the first direction D1. The second region R2 may be located between the first and third regions R1 and R3.
The sidewalls 310 of the stage 30 may include magazine guides 311 on the first region R1. The magazine guides 311 may be spaced apart from each other in the first direction D1. A distance between the magazine guides 311 spaced apart from each other in the first direction D1 may be substantially equal to or greater than the width of the magazine MZ in the first direction D1. Thus, the magazine MZ may be located between the magazine guides 311.
The magazine guides 311 may have shapes protruding from the bottom surface 320 of the stage 30 in the third direction D3. A width of an upper portion of each of the magazine guides 311 may be less than a width of a lower portion of each of the magazine guides 311. In other words, the upper portion of each of the magazine guides 311 may have a tapered shape. Thus, when the magazine MZ is placed by the pickup apparatus 10 in the third direction D3, the magazine MZ may not collide with the magazine guides 311 and may be aligned on the first region R1 of the stage 30.
The bottom surface 320 of the stage 30 may further include a conveyor belt 321 on the second and third regions R2 and R3. The conveyor belt 321 may have a shape extending in the first direction D1. The conveyor belt 321 may be located at a central portion of the bottom surface 320 of the stage 30. The conveyor belt 321 may include a conveyor motor. The conveyor motor may be located under the bottom surface 320 of the stage 30. The magazine MZ located on the second and third regions R2 and R3 of the stage 30 may be movable in the first direction D1 by the conveyor belt 321.
The bottom surface 320 of the stage 30 may further include a bump 323. The bump 323 may be located on the third region R3 of the stage 30. The bump 323 may have a shape protruding from the bottom surface 320 in the third direction D3. The magazine MZ moving in the first direction D1 may be stopped by the bump 323.
For example, the third region R3 of the stage 30 may be a work region. An operator may be positioned at a side of the stage 30, which is adjacent to the third region R3. The operator may manually provide/eject the magazine MZ onto/from the third region R3.
More particularly, the operator may provide the magazine MZ onto the third region R3 of the first stage 30a. The conveyor belt 321 of the first stage 30a may move the magazine MZ from the third region R3 to the second region R2. Thereafter, the magazine MZ may be transferred to the elevator 20 by the pickup apparatus 10.
The pickup apparatus 10 may transfer an empty magazine MZ from the elevator 20 to the second region R2 of the second stage 30b. The conveyor belt 321 of the second stage 30b may move the magazine MZ from the second region R2 to the third region R3. The operator may eject the magazine MZ from the third region R3 of the second stage 30b. Thus, the stage 30 may function as a port, in which the magazines MZ are transferred, while functioning as the buffer in which the magazines MZ temporarily wait.
Since the pickup apparatus 10 does not move onto the third region R3 of the stage 30, the operator may be spaced apart from the pickup apparatus 10. Thus, the operator may be safe from the pickup apparatus 10.

The preparing of the magazine MZ (S10) may include automatically providing the magazine MZ or manually providing the magazine MZ.
More particularly, the automatic providing of the magazine MZ may be performed by the distribution apparatus. The distribution apparatus may automatically place the magazine MZ on the distribution port 50. Thereafter, the pickup apparatus 10 may transfer the magazine MZ from the distribution port 50. The manual providing of the magazine MZ may be performed by an operator. The operator may place or locate the magazine MZ on the third region R3 of the stage 30. The conveyor belt 321 of the stage 30 may move the magazine MZ from the third region R3 to the second region R2. Thereafter, the pickup apparatus 10 may transfer the magazine MZ from the stage 30.
The transferring of the magazine MZ to the elevator (S20) may include fixing the magazine MZ by the pickup apparatus 10, raising the magazine MZ in the third direction D3 by the pickup apparatus 10, reading information (or data) of the magazine MZ using the sensor unit 150 by the pickup apparatus 10, transferring the magazine MZ in the first and second directions D1 and D2 by the pickup apparatus 10, and lowering the magazine MZ on the elevator 20 in parallel to the third direction D3 by the pickup apparatus 10.
More particularly, the fixing of the magazine MZ may be performed by the fixing unit 120 of the pickup apparatus 10. The magazine MZ may be fixed in the first and second directions D1 and D2 by the fixing unit 120 of the pickup apparatus 10. The raising of the magazine MZ in the third direction D3 and the lowering of the magazine MZ in parallel to the third direction D3 may be performed by the driving unit 110 of the pickup apparatus 10. The reading of the information of the magazine MZ may include transmitting the information of the magazine MZ to the control box 1000 by the sensor unit 150. The transferring of the magazine MZ in the first and second directions D1 and D2 may be performed by the first and second rails 10a and 10b of the upper apparatus TF.
The magazine MZ may be transferred from the distribution port 50 or the stage 30 to the elevator 20. For example, when the waiting space 220s of the elevator 20 is empty, the magazine MZ may be transferred from the distribution port 50 to the elevator 20 by the pickup apparatus 10.
The providing of the substrate in the magazine into the unit process equipment (S30) may include selecting the magazine MZ and selecting the substrate.
More particularly, the magazine MZ may be located in each of the plurality of waiting spaces 220s of the elevator 20. The magazine MZ on the upper plate 220 of the elevator 20 may be moved in the first direction D1 by the fourth motor 220m and then may be aligned with the insert apparatus 40 in the second direction D2. Since the magazine MZ is aligned with the insert apparatus 40, the magazine MZ on which the package process (i.e., the semiconductor package process) will be performed may be selected.
A plurality of the substrates may be located in the magazine MZ. A substrate may be located at the same or substantially the same level as the supply robot of the insert apparatus to come in contact with the robot, and thus the substrate may be moved toward the unit process equipment 3 in the second direction D2. In other words, one of the substrates may be located at the same or substantially the same level as the supply robot of the insert apparatus and thus the substrate on which the semiconductor package process will be performed may be selected.
The unit process equipment 3 may perform the semiconductor package process (S40). The semiconductor package process may include a molding process, a marking process, an external terminal attaching process, and/or a sawing process, but example embodiments are not limited thereto.
The ejecting of the magazine (S50) may include automatically ejecting the magazine or manually ejecting the magazine.
More particularly, the automatic ejecting of the magazine MZ may be performed by the distribution apparatus. The distribution apparatus may automatically move an empty magazine MZ located on the distribution port 50 to other unit process equipment. The manual ejecting of the magazine MZ may be performed by an operator. The empty magazine MZ may be located on the second region R2 of the stage 30 by the pickup apparatus 10. The magazine MZ may be moved from the second region R2 of the stage 30 to the third region R3 of the stage 30 by the conveyor belt 321 of the stage 30. Thereafter, the operator may manually eject the magazine from the third region R3 of the stage 30.
The substrate loading apparatus according to the inventive concepts may include the elevator capable of receiving a plurality of the magazines, and the pickup apparatus. Thus, providing the substrate in the magazine into the unit process equipment and replacing the magazine may be performed at the same time by the pickup apparatus. As a result, a total time of the semiconductor package process may be reduced.
The substrate loading apparatus according to the inventive concepts may include the stage including the conveyor belt.
