Claim 11:
12. A micro-light emitting diode (microLED) mass transfer stamping system comprising:
a fluidic assembly stamp substrate with a planar top surface;
an array of trap sites formed in the stamp substrate top surface having a first perimeter shape, a center section with a planar first depth, a distal end with a planar second depth less than the first depth, and a proximal end with the planar second depth;
a plurality of axial microLEDs, each occupying a corresponding trap site and having the first perimeter shape, a body interfaced with the trap site center section having a vertical plane body thickness greater than the trap site first depth, but less than 2× the trap site first depth, a distal electrode horizontally bisecting the body and interfaced with the trap site distal end, having a vertical plane electrode thickness greater than the trap site second depth, but less than 2× the trap site second depth, and a proximal electrode horizontally bisecting the body and interfaced with the trap site proximal end, having the electrode thickness.
