摘要
Two-dimensionally aligned and ultralarge Si grains were grown on a glassy substrate by phase-modulated excimer-laser annealing, for the first time. Grains as large as 7 mu m were grown at predetermined positions at 500 degrees C, and were expected to be aligned with less than 30 mu m pitch. Serious effects of the laser beam divergence, which is influenced by the optical system, are pointed out.
