PolyIC: high-resolution, conductive structures on transparent film

A prime example for the innovation potential of printed electronics is the most recent development of PolyIC: high-resolution, conductive structures on transparent film that are produced in a roll-to-roll production process. These conductive structures can be used as an alternative to ITO (Indium Tin Oxide) films in display, touch sensor or electric heating element applications.
Foremost regarding the limited resources of for example indium sources the development of new technologies for the production of conductive layers is a goal that numerous research and development institutes pursuit.
The new PolyIC technology is to produce transparent, conductive layers with structured and thin conductive paths made of metal with high conductivity and transparency. These conductive structures are applied on a thin and flexible film in a roll-to-roll process and can be used for example for displays, touch sensors or electric heating elements. Currently, for these applications, ITO films or thinly integrated metal wires are used.
The conductive structures by PolyIC have a resolution of 15 µm. They itself do not have to be transparent as the necessary translucence will be reached through the high-resolution structure i.e. that the conductive structures only occupy a fraction of the film (<10%). By the use of the high-resolution structure it is possible to apply light-tight, highly conductive materials such as metals. Through well-directed positioning of the process parameters it is possible to reach a conductivity of 0.4 - 1 Ω/m2 for metal. The sheet resistance of the transparent film can be adjusted to e.g. typical values of ITO films.
Compared to ITO technology, the new PolyIC process offers various essential advantages: individual layouts due to customer requirements in high-resolution will replace cost-consuming structuring methods that are necessary when using ITO films, high transparency in a huge wavelength range and an individual, customer-specific sheet resistance can be realized.
The PolyIC films can be produced in a roll-to-roll mass production process in high volume and are cost-effective in their applications. Especially the expense factor as well as limited resources asks for new technologies that can meet the demand of a steadily growing market primarily for displays and touch sensors. With this newly developed technology, PolyIC presents an attractive alternative for transparent conductive layers.

PolyIC GmbH & Co. KG

PolyIC is a leading developer of polymer electronics technology and moreover a future supplier of printed electronic products and components. The two product lines are called PolyID® and PolyLogo®. The activities are focused on providing innovative low cost electronics for mass markets.
PolyIC focuses on its expertise in materials, new adapted chip design methods as well as mature mass production processes (roll-to-roll printing) for the development of printed electronics and the goal of large-volume production.
The leading application for PolyIC is RFID (radio frequency identification). The wireless data transfer technology has the potential to be used in various electronics applications being thin, flexible, robust and low-cost.
PolyIC is a member of EPCglobal - an organization for standardizing the use of RFID in the industries as well as a founding member of the OE-A (Organic Electronics Association), a working group under the umbrella of the VDMA (Verband Deutscher Maschinen- und Anlagenbau). The OE-A promotes organic electronics internationally. Furthermore, since 2008 PolyIC is a member of AIM-D e.V., an association for automatic identification and mobile data capture.
PolyIC GmbH & Co. KG was set up in November 2003 as a joint venture between Leonhard Kurz (51%, hot stamping and coating) and Siemens (49%, electronics) for the development and production of printed polymer electronics. PolyIC is headquartered within the Nuremberg Metropolitan Region in Fuerth on the premises of Leonhard Kurz Stiftung & Co. KG.
