Light emitting element transfer system and method thereof

A light emitting element transfer system comprising:

• a vacuum chamber configured to create a vacuum atmosphere or remove the vacuum atmosphere therein;
• an alignment portion configured to align a first substrate and a second substrate inside the vacuum chamber;
• a bonding portion configured to apply heat and pressure to the aligned first substrate and second substrate and which is disposed adjacent to the alignment portion in a an arrangement direction and inside the vacuum chamber;
• and
• a stage module movably disposed between the alignment portion and the bonding portion, and including a stage including a heater, and a stage driving portion for driving the stage.

A transfer method for light emitting elements comprising:

• loading a first tray on which a first substrate is disposed and a second tray on which a plurality of second substrates are disposed, into a vacuum chamber by a second transfer portion;
• making an inside of the vacuum chamber into a vacuum state;
• transferring the first tray and the second tray to an alignment portion;
• aligning and bonding the plurality of second substrates disposed on the second tray one by one to the first substrate disposed on the first tray in the alignment portion;
• transferring the first tray on which the first substrate bonded to the second substrates is disposed, to a bonding portion by a first transfer portion;
• applying heat and pressure to the first substrate bonded to the second substrates in the bonding portion to bond the light emitting elements disposed on the second substrates to the first substrate;
• and
• removing the vacuum atmosphere from the vacuum chamber.
