LTPS produced by JIC (Joule-heating Induced Crystallization) for AMOLED TFT backplanes

  • Published : 2009.10.12

Abstract

As a Joule-heat source, a conductive Mo layer was used to crystallize amorphous silicon for AMOLED backplanes. This Joule-heating induced crystallization (JIC) process could produce poly-Si having a grain size ranging from tens of nanometers to greater than several micrometers. Here, the blanket (single-shot whole-plane) crystallization could be achieved on the $2^{nd}$ and the $4^{th}$ generation glass substrate.
