Abstract:
1. Passive stamp alignment system comprising: a stamp supported by a stamp holder; a top platform including three non-collinear balls on a surface thereof and including an opening through which the stamp slidingly extends below the top platform for subsequent contact with a substrate as the stamp holder rests on the three balls on the surface of the top platform; a bottom platform located below the stamp supporting the substrate to be aligned parallel to, and for conformal contact with, the stamp; and wherein the system is capable of moving the top and bottom platforms towards one another so as to contact the substrate with the stamp whereby the stamp holder is lifted away from each of the balls in sequence as the substrate makes contact with the stamp resulting in alignment of the stamp and substrate parallel to each other and also resulting in the stamp and substrate being in conformal contact once the stamp holder is lifted from the last ball.
