Abstract:In this study, in order to achieve high‐yield Micro‐LED chip bonding and thus further advance the breakthrough of Micro‐LED interconnect technology. In this study, an electroless plating method is used to achieve the highly uniform nickel bump arrays on thin film transistor (TFT) driver substrate. Initially, the photoresists AZ4620 and AZ2070 are chosen for the experiments, which can cover the step structure uniformly of TFT substrate. Subsequently, the morphology of bumps on the TFT substrate influenced by th… Show more
