Japan's Teijin Ltd has announced its acquisition of NanoGram Corp. which will function as it's the former's US base for the R&D and production of silicon inks with semiconductor properties.

As a wholly owned subsidiary of Teijin, NanoGram will continue its work in expanding the development of silicon-based nanoparticles, working closely with the Teijin Group's Integrative Technology Research Institute. Meanwhile, for Teijin, the capital tie-up also will enhance the Teijin Group's penetration into the market for flexible devices developed with silicon-on-plastic technologies that are integrated with Teijin Group materials such as polycarbonate resin, polyester resin and bioplastics. Samples of silicon inks will be provided to makers of LCD TFTs, solar cells and other devices, with a goal to mass produce these materials for use in the printable electronics of these manufacturers.

Printable electronics, which are electronic components manufactured through the use of various printing methods, have great promise for their ability to significantly reduce the cost of products such as thin-film transistors for liquid crystal displays (LCD TFTs) and solar cells. The market for silicon materials used these products is expected to grow to approximately $ 11 billion by 2018. The Teijin Group has been aggressively developing technologies for silicon inks with semiconductor properties, aiming to commercialize products by 2017 and eventually acquire 80 percent of the market for these materials.

The Teijin Group has placed information/electronics and environment/energy as two of its four high-growth fields going forward. In February 2009, Teijin formed a technology development agreement with NanoGram and as a result, Teijin has successfully sintered silicon nanoparticle film on a polycarbonate resin from the Teijin Group to fabricate the world's first such semiconductor device exhibiting superior transistor characteristics. The technology also can likewise be adapted for sintering on various substrates, creating a wide range of possible applications. Furthermore, the technology is expected to help reduce the weight of LCD TFTs and solar cells by over 50 percent, which would help to reduce CO2 emissions when transporting these products.
