Transportation head for microchip transfer device, microchip transfer device having same, and transfer method thereby

A microchip transfer apparatus comprising:

• a transportation head;
• a transportation arm coupled to the transportation head;
• a driver that drives the transportation arm to move the transportation head coupled to the transportation arm;
• and
• a controller configured to control the driver to control a position to which the transportation head coupled to the transportation arm moves,
• wherein the transportation head includes:
• a head body having a plurality of pickup regions and a plurality of dummy regions being non-pickup regions and each pickup region disposed between two dummy regions;
• a plurality of first protruding pins disposed in each pickup region of the head body;
• one or more second protruding pins disposed to be spaced apart from each other in each dummy region of the head body;
• and
• a liquid droplet attached to the plurality of first protruding pins,
• wherein the liquid droplet is not attached to the one or more second protruding pins,
• wherein the plurality of first protruding pins arranged to be spaced apart from each other in a first direction and a second direction intersecting the first direction in a matrix form in each pickup region of the head body, and
• wherein the one or more second protruding pins have a same height as each of the plurality of first protruding pins.

A microchip transfer method comprising:

• (a) aligning a transportation head having and a liquid droplet attached thereto with a top of a chip support accommodating a microchip thereon;
• (b) contacting the liquid droplet attached to the transportation head with the microchip mounted on the chip support and picking up the microchip from the chip support;
• and
• (c) attaching the microchip picked up using the liquid droplet of the transportation head to a substrate and transferring the microchip thereto,
• wherein the transportation head includes:
• a head body having a plurality of pickup regions and a plurality of dummy regions being non-pickup regions and each pickup region disposed between two dummy regions;
• a plurality of first protruding pins disposed in each pickup region of the head body;
• one or more second protruding pins disposed in each dummy region of the head body;
• and
• a liquid droplet attached to the plurality of first protruding pins,
• wherein the liquid droplet is not attached to the one or more second protruding pins,
• wherein the plurality of first protruding pins arranged to be spaced apart from each other in a first direction and a second direction intersecting the first direction in a matrix form in each pickup region of the head body, and
• wherein the one or more second protruding pins have a same height as each of the plurality of first protruding pins.
