Abstract:
1. A method of printing transferable components, the method comprising: forming a photo-sensitive adhesive layer on a process side of a source substrate including active components or on a patterned side of a transparent intermediate substrate; contacting the transparent intermediate substrate with the source substrate to adhere the active components on the process side to the patterned side of the transparent intermediate substrate via the photo-sensitive adhesive layer therebetween; removing portions of the source substrate opposite the process side to singulate the active components; selectively exposing portions of the photo-sensitive adhesive layer to electromagnetic radiation through the transparent intermediate substrate to alter an adhesive strength thereof; and then selectively removing portions of the photo-sensitive adhesive layer having a weaker adhesive strength to define breakable tethers comprising portions of the adhesive layer having a stronger adhesive strength, wherein the breakable tethers physically secure the active components to the transparent intermediate substrate.
