Abstract

Micro pick-and-bond heads, assembly methods, and device assemblies. In, embodiments, micro pick-and-bond heads transfer micro device elements, such as (micro) LEDs, en masse from a source substrate to a target substrate, such as a LED display substrate. Anchor and release structures on the source substrate enable device elements to be separated from a source substrate, while pressure sensitive adhesive (PSA) enables device elements to be temporarily affixed to pedestals of a micro pick-and-bond head. Once the device elements are permanently affixed to a target substrate, the PSA interface may be defeated through peeling and/or thermal decomposition of an interface layer.
