Thin-film technologies and devices have made a tremendous progress over the past decades. However, the achievable cutoff frequency of thin-film transistors remains comparatively small, which presents a severe challenge towards the realization of flexible RF electronics. The 10by10.com main objective is to combine advanced metal-oxide thin-film technologies with advanced RF circuit design methodologies to realize a technology breakthrough in high-frequency flexible electronics for wireless communication systems. This technological breakthrough is enabled by a ten-fold improvement of fT through continued device optimization and scaling and yet another ten-fold speed-enhancement through innovative harmonic circuit design techniques beyond the device cutoff frequency. As a result of phase one, this double ten-fold (10by10) performance has been reached, (i) at the level of receiver components detecting signals beyond the GHz-barrier, and (ii) on the device-level reaching fTs as high as 324MHz. The aim of the second phase is to benefit from our achievements in phase one to progress on transmitters (high-power TFTs) and to further improve the device technology and circuits to enable wireless communication beyond the GHz-barrier at the end of year 6.
