Abstract

We propose a Thin-beam Directional X' tallization (TDX) method, based on a high power, high repetition rate XeF excimer laser source and special optics, to produce a long, narrow (∼ 5 micron) beam with sharp edge slope. We present experimental results from a prototype TDX system that demonstrates very uniform directional laterally grown poly-Si films without any grain boundary protrusions.
