Comedd means Center for Organic Materials and Electronic Devices Dresden

This work is funded by European commission, the Federal Ministry for Education and Research (Bundesministerium
für Bildung und Forschung) of the German government and SMWK Saxony ministry within the framework for technology promotion by means of the European Fund for Regional Development (EFRE). On 30. October the Comedd opens the doors.

The Center for Organic Materials and Electronics Devices in Dresden (COMEDD) inside the Fraunhofer
Institute for Photonic Microsystems (IPMS) aims the customer- and application-specific research,
development and pilot fabrication of novel device concepts and manufacturing methods in the field of vacuum-processed organic materials. The activities cover three main application areas – organic-based lighting and signage technology, organic solar cell technology and OLED-on-CMOS applications. COMEDD offers research and developments on innovative fabrication equipment based on two prototype lines and three pilot-fabrication lines, a rigid / flexible substrate fabrication line (370 x 470 mm² substrates) for lighting and organic solar cell applications, an OLED-on-CMOS line on 200 mm wafer size and a roll-to-roll prototype line for flexible substrates.

The COMEDD infrastructure is located in a 900 m² class 10 state-of-the-art cleanroom inside the Fraunhofer IPMS. Based on this infrastructure COMEDD can offer product developments starting with the system concept up to pilot fabrication level.
The pilot fabrication line for 370 x 470 mm² (Gen. 2) substrates consists of a complete substrate
patterning line, an OLED deposition and encapsulation tool and necessary infrastructure. Two additional prototype deposition lines for 200 x 200 mm² substrates serve for developments and tests. Thus, complete OLED signage / lighting panels as well as organic solar cells can be manufactured.
Glass carriers laminated with the foil are used to handle flexible substrates. The whole line is dedicated for a three minute cycle time, which yields a capacity of over 80.000 panels a year.

The OLED-on-CMOS line is designed for the deposition of OLEDs on 150 mm and 200 mm wafer substrates. The line consists of an OLED deposition tool with transparent cathode deposition possibility and encapsulation system. Additional infrastructure regarding wafer test is also integrated into the concept.
The roll-to-roll fabrication line is designed as a prototype line for the development of OLED and organic solar cell processes on flexible metal foils. It consists of a substrate patterning line, an OLED / OPV deposition tool and a thin film encapsulation
system.

the field of organic-based lighting and organic solar cells, COMEDD offers customized technologies
up to pilot production level on substrate sizes up to 370 x 470 mm². The technology developments
cover substrate structuring, OLED deposition technology, encapsulation technology and system integration. COMEDD is the only service provider in Europe who can offer the complete technology setup for OLED-based lighting.

Within COMEDD a pilot roll-to-roll fabrication line will be installed till end of 2008. Using the roll-to-roll-concept, significantly lower coating costs are expected in comparison to cluster or inline concepts. Furthermore, the use of e. g. low-cost aluminium foils as substrates for the deposition of very efficient organic light-emitting diodes and solar cells is a further cost reducing step. COMEDD offers fabrication and integration technology research and development in this innovative market segment.

The OLED fabrication technology offers a new possibility to integrate highly efficient light source into silicon to establish a new class of organic based microsystems. COMEDD offers developments in this novel application area on 6” and 8” wafers. Including the driving circuitry and the integration technology, COMEDD is the only system supplier worldwide, offering product developments
starting from the system concept to the fabrication of OLED-on-CMOS devices.
