Currently, for the production of electronic devices on flexible plastic substrates taken to use materials based on organic substances. Scientists from the University of Wisconsin-Madison is considered that the potential of silicon in this case has not yet been exhausted, and the characteristics of silicon transistors on plastic basis will not be inferior to their counterparts on silicon substrates.
Daily publication on the University website reports that the technique is simple, cheap and rapid production of silicon circuits on a plastic base by roll printing.
To produce with 10 nm is used so-called nano-print lithography , when manufactured high strength stamped with subsequent cycles produce impression on the medium with the photosensitive layer. Instead of an expensive projection installation with its technological challenges, stamping simplifies a number of processes for the production of semiconductors, but also suffers from problems, for example - from the rapid wear.
stamp form is manufactured using high-precision, but very slow electron-beam projection, when the target is bombarded with a beam of electrons. Then, at the stage of forming, the manufacturing speed chip compensates for this "deficiency".
University scientists claim that obtained with the development of their transistors on a polyethylene substrate showed performance at a frequency of 38 GHz. Software process simulation suggests that this method is suitable for the creation of a 110-GHz transistors. This means that the method is suitable for the production of radio frequency chains wearable electronics. Related Products :
