摘要: Crystallization employing an N-(2-aminoethyl)-3-aminopropyltrimethoxysilane self-assembled monolayer (AEAPS-SAM) to coordinate Ni metal catalyst was found to produce large grain poly-Si. A small concentration of Ni could be deposited controllably onto an AEAPS-SAM covered with Si by immersing it in Ni solution for 1-60 min. Larger grains and a lower Ni concentration in the poly-Si could be obtained by shorter immersion. Immersion for 1 min produced grains, as large as 47 mu m and a Ni concentration as low as 7.4 x 10(18) atoms/cm(3). A poly-Si thin-film transistor fabricated with AEAPS-SAMpoly-Si of 1 min immersion had a field-effect mobility of 98 cm(2)/(V s), which is one order of magnitude higher than that of a thin-film transistor fabricated without the AEAPS-SAM treatment.
