Counterbore Pocket Structure for Fluidic Assembly

摘要

A fluidic assembly method is provided that uses a counterbore pocket structure. The method is based upon the use of a substrate with a plurality of counterbore pocket structures formed in the top surface, with each counterbore pocket structure having a through-hole to the substrate bottom surface. The method flows an ink with a plurality of objects over the substrate top surface. As noted above, the objects may be micro-objects in the shape of a disk. For example, the substrate may be a transparent substrate and the disks may be light emitting diode (LED) disks. Simultaneously, a suction pressure is created at the substrate bottom surface. In response to the suction pressure from the through-holes, the objects are drawn into the counterbore pocket structures. Also provided is a related fluidic substrate assembly.

1. A fluidic assembly method using a counterbore pocket structure, the method comprising:
providing a substrate comprising a top surface and a bottom surface, with a plurality of counterbore pocket structures formed in the top surface, with each counterbore pocket structure having a through-hole to the substrate bottom surface; flowing an ink comprising a plurality of objects over the substrate top surface; creating a suction pressure at the substrate bottom surface; and, in response to the suction pressure from the through-holes, drawing the objects into the counterbore pocket structures.
