Abstract(in English) | The characteristics of metal induced lateral crystallization (MILC) of B(BF_2)- or P-doped a-Si thin films have been investigated. Lateral growth rate in B-doped films was increased compared with that in non-doped films (conventional MILC) at 590℃. It was also found that lateral growth rate is proportional to the B dose. At low annealing temperature, needle-like Si crystallites were observed to frequently change the growth direction and branching of the crystallite during growth frequently took place in B-doped films. Besides, B-doped a-Si was densely crystallized from Ni-supply region to growth front because the epitaxial growth of a-Si from needle-like Si crystallites was enhanced by the doping effect of B atoms. On the other hand, lateral growth rate in P-doped films was decreased when the P dose is 2×10^<15>cm^<-2>. This result indicates that P atoms introduced into a-Si interrupt the diffusion of Ni. It is noteworthy that the side of needle-like Si crystallites in P-doped films are covered with the epitaxially grown crystals and consequently straightly grow. This result suggests that "turn or branch" of NiSi_2 precipitate is prevented because the width of the crystallite broadens by the epitaxial growth as soon as the needle-like Si grows by MILC |
