XDI-DCS Dielectric Ink Product

Product Summary

The thin film transistor package combines a novel dielectric ink developed at the XRCC, with a high purity, single-walled carbon nanotube ink developed by NanoIntegris. The materials package improves the overall performance of printed high-mobility p-type transistors..

Printing transistors, the next frontier in wearable and flexible electronics, offers manufacturers a low-cost way to add intelligence or computing power to a wide range of surfaces, such as plastic or fabric. Printable semiconducting and dielectric materials enable flexible tags, sensors and displays. Compatibility between semiconducting and dielectric materials is critical for reliable processing and device performance.

One of the challenges that has limited the implementation of single-walled, carbon nanotube-based thin film transistors is that they exhibit considerable hysteresis. The thin film transistor package overcomes this issue by using Xerox ink as a dielectric and encapsulant, ensuring compatibility between semiconducting and dielectric materials, and enabling reliable processing and device performance. The article, "Hysteresis free carbon nanotube thin film transistors comprising hydrophobic dielectrics" in the Journal of Applied Physics Letters discloses how this new materials package addresses these performance issues

“XRCC and NanoIntegris are providing a materials package that enables fabrication of highly functional printed electronic components,” said Brynn Dooley, manager of XRCC’s Electronic Materials Business. “This new materials solution will help our clients with their innovation mandates.”

Product Applications

The IsoSol-S100 product has been a featured material within numerous research efforts. The primary usage for the IsoSol-S100 material is for the creation of thin film transistors. What makes this material extremely appealing is that its usage enables the creation of thin film transistors that are fully printed, high-performing, flexible, stable, scalable, and low cost, with the capacity to span large areas. The addition of the dielectric promotes device stability and minimizes hysteresis.

TFT/ Logic Circuit Building Blocks [1]

The IsoSol-S100 material was ink-jet printed at 93 mg/L onto silicon test chips using <20µm drop spacing. The transistors had dense uniform network spanning the source and drain with an average hole mobilities of ~30 cm2/Vs, and on-state current densities greater than 0.75 mA/mm, with on/off ratios of 106.

Transistors were generated on flexible polyethylene terephthalate (PET) substrate with silver gate electrodes and high-k BaTiO3 dilelectric layers, printed via a R2R gravure printing process. The IsoSol-S100 was inkjet printed at 50 mg/L along with silver source/ drain contacts, defining a channel of 1000 µm x 150 µm. The on/off ratios were determined to be 7x104 with a subthreshold swing of 1.8V/decade, a transconductance of 0.26 µS/V, a threshold voltage of -2.5V, a calculated capacitance of 6.5 nF/cm2, and a mobility of 6cm2/Vs.

When the the XDI-DCS dielectric is printed as a layer atop the TFT, stability is increased, as transfer curves remain unchanged for months, and the encapsulated device exhibits minimal hysteresis (<0.2V) for voltage sweeps of ± 10V. Such encapsulated TFTs were utilized to create an inverter that maintained a constant level of output digital signal during a continuous operation time of 140 minutes and was intended to be used as building blocks for logic circuits.
