The paper “Fine-Line Conductor Manufacturing Using Advanced Drop-On-Demand PZT Printing Technology,” written by J. B. Szczech, C. M. Megaridis, D. R. Gamota and J. Zhang, has been published in the January 2002 issue of IEEE Transactions on Electronics Packaging Manufacturing.

The cover of this issue (left) shows an illustration of the selective metallization process developed by Ph.D. student John Szczech, in collaboration with Drs. D. Gamota and J. Zhang of Motorola. The process utilizes drop-on-demand ink jet printing and recent developments in non-particle fluid suspensions to fabricate file-line circuit interconnects. On the left of the shown image is an optimized jetting condition and an example (bottom left) of a trace it is capable of fabricating. The condition on the right depicts a non-optimized setting with an example of an unacceptable trace it fabricates (bottom right).

The project was funded by Motorola through the Manufacturing Research Center directed by Professor Sabri M. Cetin.
Dr. Cetin said, “The mission of the Manufacturing Research Center is to support industry-driven research in developing new technologies. Motorola has been the industry partner for this project for over four years Now, that the technology has been developed to a mature stage in close collaboration with Motorola engineers, it can be handed over to our industrial partners for commercial implementation. As University researchers, we move on to new things, like nanotechnology. This is exactly the type of project MRC is proud to support”.
