Method for manufacturing electronic device and method for removing impurity using same

A method for manufacturing an electronic device, comprising:

• placing a transfer film on a plurality of functional layers positioned apart from each other on a source substrate;
• applying pressure to a portion of the transfer film that corresponds to a first transfer object from among the plurality of functional layers through a probe to bring the first transfer target into close contact with a lower surface of the transfer film;
• applying pressure to a portion of the transfer film that corresponds to a second transfer object from among the plurality of functional layers through the probe to bring the second transfer target into close contact with the lower surface of the transfer film;
• separating the transfer film from the source substrate in a state in which the first transfer target and the second transfer target are in close contact with the lower surface of the transfer film;
• aligning the transfer film with respect to a target substrate in the state in which the first transfer target and the second transfer target are in close contact with the lower surface of the transfer film to place the transfer film on the target substrate;
• applying pressure to a portion of the transfer film corresponding to the first transfer target to place the first transfer target on the target substrate;
• separating the transfer film from the target substrate in a state in which the first transfer target is placed on the target substrate and the second transfer target is in close contact with the lower surface of the transfer film;
• aligning the transfer film with respect to the target substrate in the state in which the second transfer target is in close contact with the lower surface of the transfer film to place the transfer film on the target substrate;
• and
• applying pressure to a portion of the transfer film that corresponds to the second transfer target to place the second transfer target on the target substrate;
• and
• separating the transfer film from the target substrate in a state in which the first transfer target and the second transfer target are placed on the target substrate.

A method for removing an impurity, comprising:

• forming a functional layer on a substrate;
• placing a transfer film on a first impurity on the substrate;
• applying pressure to a portion of the transfer film that corresponds to the first impurity through a probe to bring the first impurity into close contact with a lower surface of the transfer film;
• separating the transfer film from the substrate in a state in which the first impurity is in close contact with the lower surface of the transfer film;
• placing the transfer film on a removal substrate in the state in which the first impurity is in close contact with the lower surface of the transfer film;
• applying pressure to a portion of the transfer film that corresponds to the first impurity to place the first impurity on the removal substrate;
• and
• separating the transfer film from the removal substrate in a state in which the first impurity is placed on the removal substrate.
