Materials

A world record semiconductor platform

SmartKem has designed and delivered to market a new class of semiconductor. truFLEX® offers all the advantages of inorganic and organic semiconductors in one material system. SmartKem semiconductors are designed and developed with a new type of ‘dual material’ molecular framework that allows the manufacture of highly uniform, high mobility transistor arrays using standard low-temperature solution coat production techniques.

Superior electrical and thermal stability and a 10-fold increase in mobility over traditional materials, such as a-Si, is combined with true physical flexibility in transistor form. Our proprietary organic semiconductor platform offers the display industry a route to superior TFT backplane production with reduced manufacturing complexity and cost for the first time.

SmartKem offers full ‘molecule to market’ support including a unique intrinsic material model that allows full simulation of material performance in TFT form to establish design rules for manufacture.

SmartKem also supplies a full suite of materials and process of record for TFT stack manufacture, in addition to comprehensive on-site support during the technology transfer process.

Find out why truFLEX® is a world record-breaking material system under adoption by some of the world’s biggest display manufacturers today.
