Fabricating the 25-micrometer-thick chip starts with a substrate made from polyethylene naphthalate—a plastic. ”You could compare it to the material that you use to wrap your sandwiches,” says Genoe. ”It’s very flexible.” On top, the team placed a 25-nanometer-thick layer of gold, patterned to make the circuit. Above that sits an organic dielectric, followed by a second patterned gold layer, and finally the organic semiconductor, made of pentacene.This breakthrough could lead to more thinner, cheaper, lighter and exciter mobile products in the future. There are numerous number of use cases from car dashboards, to heads up displays, environment monitors to mass consumer devices such as e-books and mobile phones.
