Abstract
An alignment system arranges a plurality of micro-elements at positions on a mounting substrate, the micro-elements are equal in dimension and shape. The alignment system encompasses a rough alignment-apparatus including a picker having capturing-probes, each of which having a capturing-face and a magnetic-force applying portion provided on the capturing-face, and a base-plate on which the capturing-probes are arrayed with an array-pattern. In the alignment system, each of the magnetic-force applying portions applies magnetic lines on the magnetic-force receptor to capture one of the micro-elements.
Claims11
A micro-element comprising:
- a functional face:
- a bottom face parallel to the functional face:
- a plurality of circumscribing-ridges connecting the functional and bottom faces;
- and
- a magnetic-force receptor allocated at a limited site on the functional face,
- wherein positions of a particular circumscribing-ridge elected among the plurality of circumscribing-ridges and the functional face are identified by the magnetic-force receptor.
An alignment system configured to arrange a plurality of micro-elements at scheduled positions on a mounting substrate, each of the micro-elements including a functional face, a bottom face parallel to the functional face, a plurality of circumscribing-ridges connecting the functional and bottom faces, and a magnetic-force receptor allocated at a limited site on the functional face, the micro-elements are equal in dimension and shape, the system comprising a rough alignment-apparatus including a picker having:
- a plurality of capturing-probes, each of which having a capturing-face made of flat plane and a magnetic-force applying portion provided on the capturing-face;
- and
- a base-plate on which the plurality of capturing-probes is arrayed with a predetermined array-pattern,
- wherein each of the magnetic-force applying portions applies magnetic lines on the magnetic-force receptor to capture one of the micro-elements, respectively, and positions of a particular circumscribing-ridge elected among the plurality of circumscribing-ridges and the functional face are identified by the magnetic-force receptor.
An assembling method including:
- shuffling a group of a plurality of micro-elements, which are equal in dimension and shape, each of which has a functional face, a bottom face parallel to the functional face and circumscribing-ridges connecting the functional and bottom faces:
- inserting a plurality of capturing-probes, each of which having a magnetic-force applying portion provided on each of capturing-faces made of flat planes, into the group of the plurality of micro-elements, and applying magnetic lines spreading from each of the magnetic-force applying portions to a magnetic-force receptor provided at a particular position of the functional face, and thereby picking up the micro-elements, whose number is equal to a number of the capturing-probes;
- and
- arraying the micro-elements picked up by the capturing-probes on a mounting substrate and assembling the micro-elements on the mounting substrate.
