Abstract
A test probe structure having a planar surface and contact locations matched to test hardware is provided. The fabrication of the test probe structure addresses problems related to the possible deformation of base substrates during manufacture. Positional accuracy of contact locations and planarity of base substrates is achieved using dielectric layers, laser ablation, injection molded solder or redistribution layer wiring, and planarization techniques.
