A Novel SPICE Compatible Current Model for OLED Circuit Simulation

Li Y., Lee B-S, Lee J.W., Lee B-S, Lee J.W., Lu C-S, Chen W-H, National Chiao Tung University, TW

high quality, and low power consumption display [1-2]. It is known that the brightness of the OLED is controlled by the current density of the device; therefore, precisely controlling the current density of active matrix [...]

KMC Simple Model for BmIn Cluster Evolution during Boron Diffusion: Theoretical or Experimental Parameters of Point Defects

Yoo J-H, Hwang C-O, Seo J., Kwon O., Won T., Inha University, KR

In this paper, we discuss a model for investigating the KMC parameters for interstitial and vacancy and we propose a novel atomistic model to explain the evolution of interstitial clusters during boron diffusion for kinetic [...]

RLC Reduction Scheme for Modeling Interconnection Line Delay in nano-CMOS Circuits

Jung C., Yoon S., Won T., Inha University, KR

In this paper we propose a realizable RLC-in-RLC-out technique to reduce parasitic parameters. The proposed technique is an efficient MOR (Model Order Reduction) method, which makes it possible to control the rise and delay time [...]

Topography Simulation for Structural Analysis Using Cell Advancing Method

Lee J-G, Yoon S., Kwon O., Won T., Inha University, KR

We propose an cell advancing method which is different but stems from the traditional cell method for accurate topography simulation. It is considered that the cell advancing method is very suitable to figure out the [...]

2D Quantum Mechanical Device Modeling and Simulation: Single and Multi-fin FinFET

Kim K., Park I-S, Won T., Inha University, KR

We propose a novel device structure (Si1-xGex/Si/Si1-xGex hetero-structure), which is called “center-channel (CC) double-gate (DG) MOSFET, ”. The device performance of the proposed FET structure was investigated with our two-dimensional quantum-mechanical simulator which is based [...]

Monte Carlo Simulation of Transport in Two-Dimensional Electron Gas via Energy Relaxation

Zhao X., Nabet B., Drexel University, US

We simulate the process of energy relaxation in two-dimensional-electron-gas (2DEG) via electron-electron (e-e) scattering by Monte Carlo method. Results indicate a sub-picosecond energy relaxation response time to external perturbation. We suggest that carriers are subjected [...]

Random Dopant Induced Fluctuations of Characteristics in Deep Sub-micron MOSFETs

Chou H-M, Lo S-C, Tsai J-H, Li Y., NCHC, TW

As the gate length of MOSFET devices shrinks down below 100 nm, the fluctuation of major devices parameter, namely, threshold voltage (VTH), subthreshold swing, drain current (ID) and subthreshold leakage current duo to influences of [...]

Monte Carlo Transport Calculations of Strained SiGe Heterostructures from Ab-Initio Band-structures

Zorman B., Krishnan S., Vasileska D., Xu J., Van Schilfgaarde M., Arizona State University, US

The continued scaling of semiconductor devices creates numerous challenges which have to be overcome in order to achieve device behavior that satisfies speed and power constraints. Possible alternatives to conventional CMOS devices include strained-Si or [...]

Hole Transport Simulations in p-channel Si MOSFETs

Krishnan S., Vasileska D., Fischetti M.V., Arizona State University, US

We use a Monte Carlo method to investigate hole transport in ultrasmall p-channel MOSFETs with gate lengths of 25 nm. To model band-structure effects like warping, anisotropy and non-parabolicity on carrier transport, our device simulator [...]

SOS Gate Capacitance Modeling

Morris H.C., Cumberbatch E.C., Abebe H., San Jose State University, US

A gate capacitance model for the SOS structure has been developed. The spatial dependence of the potential defines the changes in the charge density as well as the boundary conditions between the layers. The SOS [...]
