利用低温工艺在位置控制的大Si颗粒内形成tft是实现与大型玻璃基板上显示器的系统电路集成的一种有吸引力的方法。使用光刻技术的衬底局部结构变化允许在准激光结晶中精确定位控制大Si晶粒。采用μ-Czochraski法在a-Si薄膜的6 μm大晶粒内形成单晶Si tft。c-Si tft的场效应迁移率平均为450 cm2/Vs。本文将回顾和讨论TFT的结晶特性、扩散特性以及工艺参数的影响。
Formation of TFTs inside location-controlled large Si grains with a low temperature process is an attractive approach for realizing system-circuit integration with displays on a large glass substrate. Local structural variations of the substrate using photolithography allows an accurate location-control of the large Si grains in excimer-laser crystallization. Single-crystalline Si (c-Si) TFTs was formed inside a location-controlled large (6 μm) grain by μ-Czochraski process of a-Si film. The c-Si TFTs showed field effect mobility of 450 cm2/Vs on average. Crystallization characteristics, spread of the TFT characteristics and effects of process parameters will be reviewed and discussed.
