Abstract

Electrical characteristics of Large-grain silicon with Ni-induced crystallization which gate insulator is made of 80 nm $SiO_2$ and 20 nm SiNx was fabricated and measured with different channel widths, channel length fixed $10{\mu}m$. Focusing on the changes of channel widths from $4{\mu}m$ to $40{\mu}m$. Field-effect mobility decreased from 111.30 to $94.10\;cm^2/V_s$ when the channel widths increased. Still threshold voltage was almost similar with -1.06V.
