Printed electronics promises to enable new applications such as RFID tags, displays and various types of sensors. Critical to the development of printed electronics is the establishment of a manufacturable printing technique with high resolution and throughput. Gravure is a high-speed roll-to-roll printing technique that has many of the characteristics necessary for a viable printed electronics process...
We fabricate devices and circuit blocks using a novel, fully-printed transistor process that self-aligns source/drain electrodes to gates, resulting in improved overlap capacitance. These are used with a self-aligned interconnect to realize fully-printed transistor arrays and inverters showing performance suitable for use in a range of low-cost electronics applications.
The lack of self-alignment between the gate and the source/drain electrodes is significant problem for printed transistors, since alignment is typically limited by the layer-to-layer registration capabilities of the printer. This in turn necessitates the use of design rules specifying large gate-to-source/drain overlaps, resulting in degraded switching speed due to the large overall capacitance [1]...
In this paper we demonstrate the design and development of a small-size, sheet-fed gravure printer which can achieve 10 mum alignment of multiple layers and requires less than 200 muL of ink per print. Using this printer we demonstrate highly-scaled metallic silver lines, 20 mum wide, printed with nano-particle and precursor based inks. We describe some scaling trends which are specific to the printing...
