As a result, a column of picked-up semiconductor chips can be flipped-over while simultaneously changing the alignment direction thereof with a simple constitution.

A system for performing a direct transfer of a plurality of semiconductor die from a first substrate to a second substrate based on map data of the location of the semiconductor die. A first conveyance mechanism conveys the first substrate. A second conveyance mechanism conveys the second substrate. A transfer mechanism is disposed adjacent to the first conveyance mechanism to effectuate the direct transfer. A controller causes one or more processors to perform operations including: determining positions of the plurality of semiconductor die based at least in part on map data, conveying at least one of the first substrate or the second substrate such that the first substrate, the second substrate, and the transfer mechanism are in a direct transfer position, and activating the transfer mechanism to perform the direct transfer of the plurality of semiconductor die.

Embodiments relate to forming an elastomeric interface layer (elayer) with a flap over multiple light emitting diode (LED) dies by forming materials across multiple LED dies and removing the materials between the LED dies. The formed flap of the elayer provides a large surface area for adhesion between each LED and a pick-up surface. For example, the flap may have a surface area that is larger than the light emitting surface of the LED die, or larger than the surface area of an elastomeric interface layer without the flap. As such, the elayer allows each LED to be picked up by a pick-up surface and placed onto a display substrate including control circuits for sub-pixels of an electronic display. In some embodiments, the LED dies are micro-LED (?LED) dies.

A display apparatus includes a substrate and a plurality of LEDs. Each LED is attached to the substrate via conductive pads on a side of the LED. A diffuser having light diffusing characteristics is aligned with the plurality LEDs against a surface of the substrate. The diffuser is aligned so as to nest around at least one LED of the plurality of LEDs.

The invention relates to an apparatus and a method for mounting components on a substrate. The apparatus comprises a bond head with a component gripper, a first drive system for moving a carrier over relatively long distances, a second drive system which is attached to the carrier for moving the bond head back and forth between a nominal working position and a stand-by position, a drive attached to the bond head for rotating the component gripper or a rotary drive for rotating the substrate about an axis, at least one substrate camera attached to the carrier and at least one component camera.
