In this paper a potential based model for monocrystalline silicon thin film transistor (TFT) systems on glass (SOG) substrate from the accumulation to the strong-inversion region is developed. By solving the complete dimensional (1D) Poisson's equation, the potential distribution in the channel is obtained. The analytic drain current is expressed accurately base on the potential solution. Compared...
ULTRA-SOI is a new generation of the channel-potential-based non-charge-sheet model for the dynamic depletion (DD) Silicon-On-Insulator (SOI) MOSFET, developed by TSRC group in EECS department of Peking University with many year efforts. The model is formulated with a fully physical derivation from the Poisson's equation to solve the potential along the vertical direction of the silicon film. The...
This paper presents a new and more accurate potential based model for bulk MOSFET compared to the traditional charge-sheet surface potential model. The channel potential of the bulk MOSFET is obtained by solving Poisson equation and an accurate current expression is obtained base on it. Taking Pao-Sah model as a standard, the relative errors of the charge-sheet model may be as large as 4% in the saturation...
An analytic surface potential based non-charge-sheet model for poly-silicon thin film transistors (poly-Si TFTs) is proposed in this paper with consideration of the substrate and film thickness effects. The 1-D Poissonpsilas equation with dopant, mobile, and the trap charge terms is first solved to obtain accurate yet continuous channel potentials physically. An analytic non-charge-sheet drain current...
