An Accurate and Versatile ED- and LD-MOS Model for High-Voltage CMOS IC Spice Simulation

Tudor B., Wang J.W., Hu B.P., Liu W., Lee F., Synopsys, Inc., US

The paper presents a high-voltage compact MOSFET model that has been proven physically accurate and numerically robust for various and generations of high-voltage ED (extended drain) and LD (laterally double diffused) production CMOS process technologies. [...]

Compact Model Methodology for Dual-Stress Nitride Liner Films in a 90nm SOI ULSI Technology

Williams R.Q., Chidambarrao D., McCullen J.H., Narasimha S., Mitchell T.G., Onsongo D., IBM Corporation, US

This work presents a novel methodology for a physically-based, layout-dependent nitride liner stress model that works with readily-available compact models. The methodology includes a data-calibrated, semi-empricial model and is tightly-coupled to circuit netlist extraction for [...]

TCAD-based Process Dependant HSPICE Model Parameter Extraction

Mahotin Y., Tirumala S., Lin X-W, Pramanik D., Synopsys, Inc., US

This paper describes the methodology for global extraction of HSPICE compact model parameters as explicit polynomial functions of process parameter variations (halo dosage, gate oxidation temperature etc). Electrical data required for extraction is obtained from [...]

DNA Extraction with Parallel Electrodes on Microfluidic System

Parng S.H., Shia T.K., Yang H.J., Kuo C.H., Microsystem Technology Common Laboratory, TW

DNA trapping was demonstrated between an electrical field across two parallel integrated electrodes on chip fabricated by the MEMS techniques. The method to release the trapped DNA molecules using reversed voltage control electrical field was [...]

New Guidelines for Selecting Best Extraction Methods of EPS Using Atomic Force Microscopy

Kang S., Ahn Y., Choi H., Elimelech M., Yale University, US

In this study, we applied AFM to develop the guideline during the selection of best extraction methods for exocellular polymeric substances (EPS). A single cell of S. cerevisiae was glued at the end of the [...]

Unambiguous Extraction of Threshold Voltage Based on the Transconductance-to-Current Ratio

Cunha A.I.A., Schneider M.C., Galup-Montoro C., Caetano C.D.C., Machado M.B., Federal University of Santa Catarina, BR

This paper presents a very simple methodology for determining the threshold voltage. The procedure is based on the expressions of the Advanced Compact MOSFET (ACM) model, valid in all regimes of operation, which assures physical [...]

Extraction of Mosfet Effective Channel Length and Width Based on the Transconductance-To-Current Ratio

Cunha A.I.A., Schneider M.C., Galup-Montoro C., Caetano C.D.C., Machado M.B., Federal University of Santa Catarina, BR

This paper presents a very simple methodology for determining the effective channel length and width, which is independent of the determination of the threshold voltage. The procedure is based on measurement of the transconductance-to-current ratio [...]
