【摘要】 本文报道了薄膜ＳＩＭＯＸ／ＳＯＩ材料上全耗尽ＭＯＳＦＥＴ的制备情况，并对不同硅膜厚度和不同背面栅压下的器件特性进行了分析和比较．实验结果表明，全耗尽器件完全消除了＂Ｋｉｎｋ＂效应，低场电子迁移率典型值为６２０ｃｍ２／Ｖ·ｓ，空穴迁移率为２１０ｃｍ２／Ｖ·ｓ，泄漏电流低于１０－１２Ａ；随着硅膜厚度的减簿，器件的驱动电流明显增加，亚阈值特性得到改善；全耗尽器件正、背栅之间有强烈的耦合作用，背表面状况可以对器件特性产生明显影响．该工作为以后薄膜全耗尽ＳＩＭＯＸ／ＳＯＩ电路的研制与分析奠定了基础．更多还原

【Abstract】 Abstract The fabrication of fully depletede MOSFET’s with high performance on thin film SIMOX/SOI material is presented. The experimental results show that electron and hole low field mobilities are 620cm2/V. s and largely increase the current drivability along with the decrease Of silicon film thichkness. The condition of the back surface can greatly influence the device characterristics by the coupling between front and back gates. This work lays a foundation of thin film fully depletde SIMOX/SOI circuit fabrication.更多还原
