Abstract

Northwestern University researchers have developed a hot pressing method for producing patterned transistors and circuits. These devices can then be integrated into flexible electronics with a wide range of applications- from wearable consumer products to implantable medical devices. One drawback of alternative methodologies is that they have never been used on patterned substrates. This innovative method from the Marks group will enable deposition of thin film dielectrics onto patterned substrates without loss of insulating characteristics, dielectric strength or smooth surface morphology. Importantly, this hot pressing method is inexpensive, scalable and utilizes low fabrication temperatures, which makes it compatible with plastic substrates. Due to these favorable characteristics, this novel technology could open new routes for fabricating printed electronics.
