Orthogonal Photolithography is a patented technology, pioneered by Fraunhofer COMEDD group leader Dr. Alex Zakhidov. It takes advantage of the fact that the vast majority of organic materials are either oleophilic or hydrophilic and are hence orthogonal to highly fluorinated chemicals. Therefore, appropriate fluorinated photoresists can be used to pattern organic layers without compromising the performance of organic devices. The availability of such orthogonal photoresists promises to enable the fabrication of complex device structures, expanding the range of possibilities for organic electronics. Fraunhofer COMEDD established Orthogonal Photolithography in its clean room and incorporated it into a 200-mm wafer microdisplay pilot fabrication line.

Quantum-Dot Enhanced Film
Each sheet of Quantum Dot Enhancement Film (QDEF) contains trillions of tiny quantum dots. The dots produced are tuned to create better color by changing their size during fabrication to emit light at just the right wavelengths. Conventional light-emitting materials such as crystal phosphors have a broad fixed spectrum. Quantum dots can actually convert light to nearly any color in the visible spectrum. For the first time, display designers have the ability to tune and match the spectrum more accurately to color filters. This leads to LCDs with perfectly accurate color and power-sipping energy efficiency.

Gold-Plated Flat Flexible Cable
Nicomatic is now offering gold-plated flat flexible cable (FFC). Similar to tin-plated FFC, gold-plated FFC provides board-to-board interconnectivity. Additionally, it is also capable of mating with standard ZIF/LIF connectors. However, non-gold plating is more susceptible to corrosion from contaminants such as oils, chemicals, and water, whereas gold-plating prevents corrosion. In fact, gold-plated FFC mating to gold connectors will have no galvanic corrosion, even in harsh and demanding environments. Gold plating also prevents problems with whiskering and oxidation. Gold plating allows for a greater life cycle as well. While tin takes only 50 insertions/extractions, gold can do 10 times as many.
