  • Publication number: 20210300098
    Abstract: A micro-transfer structure comprises a stamp comprising a rigid support, only a single contiguous bulk layer disposed on the rigid support, and posts disposed on the bulk layer. Components are adhered to (e.g., disposed in contact with) some but not all of the posts. The posts can be substantially identical and disposed in a regular array on the bulk layer. Each component is adhered to (e.g., in contact with) two or more posts. Components can be disposed on a source wafer entirely over sacrificial portions of a sacrificial layer on or in the source wafer and attached to anchors disposed between sacrificial portions with a tether.

  • Patent number: 11127889
    Abstract: A method of making a display structure comprises providing a display substrate having a display surface, disposing components on and in contact with the display surface, uniformly blanket coating the display surface with a curable layer of uncured light-absorbing material, and curing the curable layer of uncured light-absorbing material to provide a layer of cured light-absorbing material so that the components project from the layer of cured light-absorbing material without having pattern-wise etched the layer of cured light-absorbing material after the light-absorbing material has been cured. The uniform blanket coating has a thickness greater than a thickness of the component, disposing the components comprises printing the components through the uniform blanket coating such that the components protrude from the uniform blanket coating, or the component is coated with a de-wetting material.

  • Publication number: 20210288235
    Abstract: A method of making a surface-mountable pixel engine package comprises providing an array of spaced-apart conductive pillars and an insulating mold compound laterally disposed between the conductive pillars on a substrate together defining a planarized surface. Pixel engines comprising connection posts are printed to the conductive pillars so that each of the connection posts is in electrical contact with one of the conductive pillars. The pixel engines are tested to determine known-good pixel engines. An optically clear mold compound is provided over the planarized surface and tested pixel engines. Optically clear mold compound is adhered to a tape and the substrate is removed. The optically clear mold compound, the insulating mold compound, the conductive pillars, the optically clear mold compound, and the tested pixel engines are singulated to provide pixel packages that comprise the pixel engines and the known-good pixel engines are transferred to a reel or tray.

  • Patent number: 11088121
    Abstract: A method of micro-transfer printing comprises providing a component source wafer and components disposed in, on, or over the component source wafer. A destination substrate and a stamp for transferring the components from the component source wafer to the destination substrate is provided. The component source wafer has an attribute or structure that varies across the component source wafer that affects the structure, operation, appearance, or performance of the components. A first array of components is transferred from the component source wafer to the destination substrate with a first orientation. A second array of components is transferred from the component source wafer to the destination substrate with a second orientation different from the first orientation. Components can be transferred by micro-transfer printing and different orientations can be a different rotation, overlap, interlacing, or offset.

  • Patent number: 10937679
    Abstract: An example of a printed structure comprises a target substrate and a structure protruding from a surface of the target substrate. A component comprising a component substrate separate and independent from the target substrate is disposed in alignment with the structure on the surface of the target substrate within 1 micron of the structure. An example method of making a printed structure comprises providing the target substrate with the structure protruding from the target substrate, a transfer element, and a component adhered to the transfer element. The component comprises a component substrate separate and independent from the target substrate. The transfer element and adhered component move vertically toward the surface of the target substrate and horizontally towards the structure until the component physically contacts the structure or is adhered to the surface of the target substrate. The transfer element is separated from the component.
