Organic light-emitting diodes integrated on silicon

08.03.2007
So far there is no technology capable in combining monolithic integration of highly efficient and stable light sources into standard silicon CMOS. For the first time OLED technology allows both large-area deposition and micro-patterning of light emitters on top of uppermost metal layers of CMOS chips.

Therefore CMOS active area space below the OLED electrode is available for additional circuitry in a System-on-Chip setup, including OLED driving (as minor part of it). OLED processing is performed by post-processing at wafer-level. return of the wafers into CMOS processes is not required. Major applications are expected for microdisplays and optoelectronics (organic microsystems).

Applications microdisplays:

- electronic viewfinder
- projection
- head mounted displays (mobile communication, consumer electronic, ...)
- optical inspection
- patterend illumination
Applications optoelectronics:
- light barriers (reflection type)
- opto-couplers
- optical sensors (chemical, medical --> fluorescence, photoplethysmography,...)
- communication (chip-to-chip, board-to-board, chip-to board)
Additonally the OLED fabrication technology offers firstly the possibility to integrate highly efficient light source into silicon to establish a new class of organic based microsystems. The Fraunhofer IPMS offers developments in this novel application area. At the Smart System Integration show 2007 in Paris the Fraunhofer IPMS is going to present highly efficient OLEDs integrated into silicon backplanes in the form of rows or arrays for opto electronic and microdisplay applications.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
