thinfilm_printedmemoryThin Film Electronics and InkTec say that they have produced fully functional printed nonvolatile memory products in a high-volume roll-to-roll printing process. The collaboration between the Norwegian and Korean companies has been successfully completed to demonstrate fully R2R printed memories with a layout and device structure developed by Thinfilm, targeting applications such as game cards and toys.

The work has been conducted under a joint development agreement between Thinfilm and InkTec that began in June 2008.

The companies say the R2R production-worthy printing process can achieve yields of 96-97% on the printed memory cells for the best device structure. Several rolls, each with more than 100m of printed memory, have been produced with a total of five printing steps, according to the partners. The printed memory film thickness is about 200nm.

Much of the JDA work has been focused on developing inks suitable for the realization of the desired target. The electrodes' ink compositions are based on InkTec’s proprietary transparent non-particle-based silver complex compound, while the memory ink uses a proprietary functional ferroelectric polymer jointly developed by Thinfilm and Solvay Solexis.

"This is to our knowledge one of the world first established R2R processes capable of producing electronic components other than conductors and antennas with high yield," said Thinfilm CEO Johan Carlsson. "This also confirms to us that InkTec’s new factory is ideally suited for volume production of our memories and that the InkTec’s staff has the right skills to achieve quality results. In addition, their market presence in more han 100 countries will help us in commercializing our technology on a broader scale."

"We are very proud of our unique electronic ink as well as our printing facilities in our second factory in Pyungtaek-city where this work has been conducted," stated InkTec CEO Kwang-Choon Chung. "These results enable us to add yet another application to our successful print services business, as we now will be able to offer fully printed Thinfilm memories to our own, as well as Thinfilm’s customers. In the future, we see Thinfilm's memory technology as an important and integral part of printed RFID products."

Ok, they talk about the thickness of printed layer, but they nothing to say about the density of the elements (TFT as I think) in the single memory chip
