Realizing the tremendous demand and commercialization potential of flexible electronic components for modern systems, Omega Optics, Inc., together with the University of Texas at Austin, propose Low-Cost, High Throughput, Roll-to-Roll Ink-Jet Manufacturing of Hybrid Electronic Systems on Flexible Substrates. In the Phase I program, using an ink-jet developed 2-bit 1x4 Phased Array Antenna (PAA) system, beam steering of 3GHz signal from 0 to 13.6 degrees was demonstrated on a flexible substrate. Bottom illuminated organic solar cells were fabricated, and using a new type of copolymer, diketopyrrolopyrolecopolymers, a high PCE of 4.7% was achieved. In the Phase II program, high-rate roll-to-roll manufacturing of organic and inorganic electronic devices on flexible substrates will be investigated. Key manufacturing related issues such as in-line alignment control, quality assurance, etc, will be addressed. Using a customized ink-jet print engine, high-rate development of electronic components will be performed. Gaining vital information from a single ink-jet printer, a two-stage continuous high-rate roll-to-roll ink-jet printing system with print speeds of 20-30m/min at throughput of 150m^2/hr will be developed. As a proof of concept of this enabling technology, high throughput manufacturing of solar cell powered flexible PAA communication system on a Kapton substrate, a common material used for PC board, is proposed. These objectives are targeted at developing unique multifunctional inorganic, organic and bio-inspired hybrid electronic system architectures on flexible substrates that can only be achieved with printing.
