摘要:采用化学溶液沉积法,用价格低廉的原料成功地制备了Bi2Ti2O7介质膜.制膜过程简单,成本低廉,得到的薄膜具有良好的绝缘性和较高的介电常数.用其制备的绝缘栅场效应管与相同尺寸的SiO2绝缘栅场效应管相比,前者具有较高的跨导和较低的开启电压.

关键词: Bi2Ti2O7薄膜, 介电常数, 绝缘栅场效应管

Abstract: The Bi2Ti2O7 thin film was successfully prepared by chemical solution deposition technique on n-Si (100) using bismuth nitrate and titanium butoxide as the starting materials.The film presents very good insulating property and has relatively high dielectric constant.Compared with the SiO2 insulation gate field effect transistor of the same size,it  can greatly increase the transconductance and lower the   cut-in voltage.

Key words: Bi2Ti2O7thin film;dielectric constant, insulation gate field effect transistor
