Abstract:
1. A method for transferring integrated circuits to a substrate moving in a first direction, the method comprising: (a) continuously rotating a rotary unit in-step and in a first rotational direction between a wafer bed and the substrate, the wafer bed including a membrane that supports the integrated circuits; (b) selecting one of the integrated circuits; (c) aligning the selected integrated circuit with the rotary unit having pickup members externally placed about the rotary unit; (d) piercing the membrane of the wafer bed adjacent the supported selected integrated circuit with one of the pickup members; (e) taking the selected integrated circuit from the wafer bed with the one of the pickup members through the membrane; (f) moving the selected integrated circuit about the rotating rotary unit in-step to the moving substrate; and (g) placing the selected integrated circuit on the substrate moving in the first direction.
