HiSIM-SOTB: A Compact Model for SOI-MOSFET with Ultra-Thin Si-Layer and BOX

Miura-Mattausch M., Kikuchihara H., Feldmann U., Nakagawa T., Miyake M., Iizuka T., Mattausch H.J., Miura-Mattausch M., Hiroshima University, JP

The Silicon-On-Thin-Buried-Oxide (SOTB) transistor is a descendant of the conventional SOI MOSFET with thin Silicon and BOX layers. Many different structure and material variations are possible, where the choice of a thicker BOX may be [...]

Modeling of the impurity-gradient effect in high-voltage MOSFETs

Maekawa Y., Fukushima K., Tanaka A., Kikuchihara H., Miyake M., Mattausch H.J., Miura-Mattausch M., Miura-Mattausch M., Hiroshima University, JP

Two major high-voltage MOSFET types are commonly used by semiconductor industries. One has a symmetrical structure, and the other has a laterally-diffused asymmetric structure called LDMOS. Here our focus is the LDMOS structure, where an [...]

Computation Efficient yet Accurate Surface Potential Based Analytic Model for Symmetric DG MOSFETs to Predict Current-Voltage Characteristics

Song Y., Zhang J., Zhang L.N., Zhang J., Zhang L.N., Zhuang H., Che Y.C., He J., Chan M., Peking University, CN

A computation efficient yet accurate surface potential-based analytic model for the symmetric double-gate MOSFETs is proposed to simulate double-gate device current-voltage characteristics in this paper. This model consists of a surface potential versus voltage input [...]

A Complete Analytic Surface Potential-Based Core Model for Undoped Cylindrical Surrounding-Gate MOSFETs

He J., Zhang J., Zhang L., Zhang J., Zhang L., Ma C., Chan M., Peking University, CN

An analytic surface potential-based non-charge-sheet core model for cylindrical undoped surrounding-gate (SRG) MOSFETs is presented in this brief. Starting from the exact surface potential solution of the Poisson’s equation in the cylindric surrounding-gate (SRG) MOSFETs, [...]

Advanced Compact Models for MOSFETs

Watts J., McAndrew C., Enz C., Galup-Montoro C., Gildenblat G., Hu C., van Langevelde R., Miura-Mattausch M., Rios R., Sah C-T, Joint Paper, US

The combination of decreasing MOSFET dimensions and increasing use of MOSFETs for analog and RF application has created the need for advanced compact models for MOSFET circuit design. The first generation of MOSFET models rely [...]
