Compact Modeling of Doped Symmetric DG MOSFETs with Regional Approach

Chandrasekaran K., Zhu Z.M., Zhou X., Shangguan W., See G.H., Chiah S.B., Rustagi S.C., Singh N., Nanyang Technological University, SG

A compact model for the explicit surface potential equation of doped symmetric double-gate MOSFET from Poisson equation with regional approach is presented. It’s scalable for all doping and channel thicknesses and has been proved to [...]

Comprehensive Characterization and Analysis of RTS, 1/f, RF Noise and Power Performances of Schottky-Diode in Standard CMOS

Xiong Y.Z., Lo G.Q., Loh W.Y., Shi J.L., Yu M.B., Loh W.Y., Kwong D.L., Institute of Microelectronics, Singapore, SG

This study presents comprehensive characterization of Schottky-diode in standard CMOS on its DC, low-frequency and RF noise performance. Random-telegraph-signal (RTS) and 1/f noise have been characterized, along with RF noise, power performances analysis. Results showed [...]

Scalable MOSFET Short-channel Charge Model in All Regions

See G.H., Chiah S.B., Zhou X., Chandrasekaran K., Shangguan W., Zhu Z., Lim G.H., Pandey S.M., Cheng M., Chu S., Hsia L.-C., NTU, SG

Short-channel effects (SCEs) for both intrinsic chargesand extrinsic capacitances need to be modeled when theMOSFET channel is short. The intrinsic SCEs are modeled using bulk-charge sharing and quasi-two dimensional potential barrier loweirng; extrinsic overlap capacitances [...]

Unified Approach to Bulk/SOI/UTB/s-DG MOSFET Compact Modeling

Zhou X., Chandrasekaran K., Chiah S.B., Shangguan W., Zhu Z., See G.H., Mani Pandey S., Lim G.H., Rustagi S., Cheng M., Chu S., Hsia L.-C., Nanyang Technological University, SG

In this paper, we extend our unified regional approach to bulk-MOS charge modeling with non-pinned surface potential for various device structures such as PD/FD/UTB SOI and s-DG MOSFETs, including strained-Si channel. The regional solutions make [...]

Adaptive temperature estimation in 3D single-cell dielectrophoretic traps using the boundary Element Method

Rosales C., Institute of High Performance Computing, A*STAR, SG

Application of dielectrophoresis techniques to biological particles is limited by the temperature increase of the suspension due to Joule heating. This temperature increase can be obtained from a Poisson equation, but the presence of the [...]

Fabrication of Periodic Sub-100nm Patterns in SiO2 Template by Electron-beam Lithography

Chen A., Chen P., Chua S.J., Chen A., Chen P., Singapore-MIT Alliance, National University of Singapore (NUS), SG

We report on the fabrication process of SiO2 templates with periodic sub-100nm air hole patterns using electron beam (e-beam) lithography followed by reactive ion etching (RIE). Two-dimensional periodic air holes with sub-100nm dimensions were defined [...]

Interpretation of Anomalous Photoluminescence Peak in GaAs1-xNx Grown by Molecular Beam Epitaxy

Fan W.J., Cheah W.K., Yoon S.F., Zhang D.H., Liu R., Wee A.T.S., Nanyang Technological University, SG

Low-temperature (10K) photoluminescence (PL) measurements of GaAs1-xNx epitaxial layers grown on GaAs by solid-source molecular beam epitaxy (SSMBE) reveal an anomalous second peak. Rapid thermal annealing (RTA) of a specific GaAsN sample reveals a lower [...]

Facile Assembly of Nanoparticles into 2D Micro-structured Films by a Polymer-aided Self-organization Process

Nurmawati M.H., Ajikumar P.K., Renu R., Valiyaveettil S., National University of Singapore, SG

There have been many reported approaches for tailoring the properties of nanomaterials by manipulating the way in which they order on several different length scales. The self-assembly of micro- and nano-structures in periodic arrangement of [...]
