The proposed solution includes a planar near field antenna bonded to an RFID tag, which is printed on flexible foil using an organic complementary TFT technology. Thanks to an active envelope detector, ASK modulation with modulation depth as low as 20% can be adopted to increase the available input power for the rectifier. The RFID functionality is demonstrated at the internally generated supply voltage of 24 V, for a reading range of 2-5 cm and a bit-rate up to 50 bit/s. With more than 250 transistors on the same foil, this work represents the most complex circuit ever published in a printed organic complementary TFT technology.Index Terms-ASK modulation, active detection, mixed analog-digital circuits modulation index, organic circuits, pentacene, polyimide, radio frequency identification, sub...

The concept of microfluidics on foil opens up new opportunities for combining the advantages of having a flexible substrate with reel-to-reel processing, which has the potential to be the basis for extremely cheap micro products. To reach this goal, foil substrates must be combined with micro-manufacturing technologies that are well adapted to these substrates. Some technologies are already available, some are the subject of current research, and some still have to be conceived. In the current paper, technologies such as reel-to-reel embossing, reel-to-reel laminating, and laser ablation/cutting as well as laser welding will be discussed. The discussions include a brief review of the state of the art as well as a report on latest research results stemming from research by the present authors. Furthermore, this paper shows the vision of what can be achieved if foil-based technologies, such as polymer (opto-) electronics and microfluidics are combined. A polymer electronics-based alcohol sensor is presented as an example system

Ultra thin silicon ICs with a remaining thickness of less than 30 µm are investigated with respect to their manufacturing technology and mechanical behavior. Thin wafers which were diced using a standard sawing process reveal low fracture resistance when a bending force is applied to single chips. To eliminate influence of micro-cracks induced by sawing extremely thin wafers, the new concept "Dicing by Thinning" was developed and is explained in the paper. The concept allows manufacturing of 10 - 30 µm thin wafers and includes self-acting die separation during thinning procedure. Best results are achieved when dicing lines between chips are prepared at front side of wafer by dry etching methods. First results of analysing mechanical reliability of thin silicon samples are presented and discussed

The recent technological advances in micro/nanotechnology present new opportunities to combine microfluidics with microarray technology for the development of small, sensitive, single-use, point-of-care molecular diagnostic devices. As such, the integration of microarray and plastic microfluidic systems is an attractive low-cost alternative to glass based microarray systems. This paper presents the integration of a DNA microarray and an all-polymer microfluidic foil system with integrated thin film heaters, which demonstrate DNA analysis based on melting curve analysis (MCA). A novel micro-heater concept using semi-transparent copper heaters manufactured by roll-to-roll and lift-off on polyethylene naphthalate (PEN) foil has been developed. Using a mesh structure, heater surfaces have been realized in only one single metallization step, providing more efficient and homogenous heating characteristics than conventional meander heaters. A robust DNA microarray spotting protocol was adapted on Parylene C coated heater-foils, using co-polymer poly(DMA-NAS-MAPS) to enable covalent immobilization of DNA. The heaters were integrated in a microfluidic channel using lamination foils and MCA of the spotted DNA duplexes showed single based discrimination of mismatched over matched target DNA-probes. Finally, as a proof of principle, we perform MCA on PCR products to detect the Leu7Pro polymorphism of the neutropeptide Y related to increased risk of Type II diabetes, BMI and depression.

Cost effective and high quality processes are needed for further development of flexible electronic systems. Applications of these structures are e. g. in the field of high density interconnection foils or polymer electronics. In this paper a lithography process for patterning copper on flexible foils using reel-to-reel methods is presented. The process allows the fabrication of well defined copper structures with typical feature sizes from 15 to 40 µm using either etching or electro plating technology. Properties of the dry film photoresist used in the process as well as details of the technology are described. Influences of photol ithography and etching on dimensional accuracy and resolution are given and some consequences on design rules are shown
