Abstract
Embodiments of the invention relate generally to directed self-assembly (DSA) and, more particularly, to the DSA of electronic components using diamagnetic levitation.
Claims20
A method of assembling a plurality of diamagnetic components, the method comprising:
- depositing a plurality of diamagnetic components onto a magnetic stage, the magnetic stage comprising a plurality of magnets arranged in an array;
- and
- applying a vibratory force to the magnetic stage,
- wherein, applying the vibratory force moves at least one of the plurality of diamagnetic components to a stable levitation node of the magnetic stage.
1 more element
A system for directed self-assembly of diamagnetic components, the system comprising:
- a magnetic stage comprising:
- a plurality of magnetic devices arranged in an array with alternating and opposite magnetic orientations;
- and
- a surface disposed above the plurality of magnetic devices;
- and
- at least one device operable to deliver a vibratory force to the magnetic stage,
- wherein the vibratory force is sufficient to move a diamagnetic component on the surface of the magnetic stage to a stable levitation node of the magnetic stage.

A method of assembling a plurality of diamagnetic components, the method comprising:
- depositing a plurality of diamagnetic components onto a magnetic stage, the magnetic stage comprising a plurality of magnets arranged in an array;
- and
- repeatedly applying a vibratory force to the magnetic stage to move at least one of the plurality of diamagnetic components to one of a plurality of stable levitation nodes of the magnetic stage but no more than one diamagnetic component to each of the plurality of stable levitation nodes,
- wherein the plurality of magnets are arranged in an array selected from a group consisting of:
- a checkerboard array with alternating north and south poles and a two-dimensional Halbach array and applying the vibratory force causes each of the stable levitation nodes to be filled by no more than one diamagnetic component.
