A loader includes a pre-aligner and a transporter. The pre-aligner includes a base, a moving mechanism, a platform and a sensing unit. The moving mechanism includes an axle inserted in the base. The platform is coaxially connected to the axle and formed with a fetching face operable for generating an electrostatic field to attract a substrate. The sensing unit is located on the base and operable for sensing an orienting portion of the substrate. The transporter includes a fork formed with a fetching face operable for generating an electrostatic field to attract the substrate.

An adsorption device includes a substrate and a magnetic film on a surface of the substrate. The substrate has magnetic properties and is capable of generating magnetic field. The magnetic film partially covers the surface. The magnetic film generates a magnetic field having a direction that is opposite to a direction of the magnetic field generated by the substrate. Portions of the surface of the substrate not covered by the magnetic film form positions to attract and adsorb target objects, and other portion of the surface of the substrate covered by the magnetic film is not able to attract any target object.

A device to attract and hold microscopic items such as micro LEDs magnetically rather than by static electricity includes a substrate and a plurality of magnetic units on a surface of the substrate. The magnetic units are spaced apart from each other and are constrained in the size and direction of their individual magnetic fields. Each of the magnetic units includes a magnet and a cladding layer partially covering the magnet. The cladding layer is made of a magnetic material. A side of the magnet away from the substrate is exposed from the cladding layer to attract and hold one micro LED.
