Alignment module for transferring a magnetic light-emitting die and alignment method thereof

Abstract

An alignment module and alignment method for transferring magnetic light-emitting die are provided, including a backplane having at least one cavity, a magnetic pull device and magnetic light-emitting die. The magnetic pull device is located below the cavity and disposed correspondingly to the cavity. The magnetic light-emitting die includes a magnetic metallic substrate and a peripheral electrode formed on the magnetic metallic substrate. The peripheral electrode is surrounding on the magnetic metallic substrate and formed adjacent to an inner edge of the magnetic metallic substrate. Depth of the cavity is designed as equal to a thickness of the magnetic metallic substrate such that the die is accommodated and aligning transferred to the backplane by using the cavity and magnetic pull device. By employing the proposed die alignment techniques, accurate alignment result is achieved and thereby the present invention is applied perfectly for industrial mass transfer technology.
