چکیده

Non-uniformity of the dielectric properties of highmaterial due to random grain orientation and phase separation will lead to variation in characteristics between different devices. Here we present a model for phase separated highdielectrics and investigate, by means of 3D numerical device simulation, the intrinsic parameter fluctuations which result from this structural non-uniformity.

Intrinsic Parameter Fluctuations due to Random Grain Orientations in High-κ Gate Stacks

As the scaling of MOSFETs continues the requirement to maintain electrostatic integrity dictates an aggressive reduction of the oxide thickness below 1 nm, introducing intolerably high gate leakage [1]. This has led to the introduction of high-κ materials in the gate stack offering the required SiO2 equivalent oxide thickness at increased physical thickness and reduced gate leakage. There are m...

A 3-D Atomistic Study of Archetypal Double Gate MOSFET Structures

The double gate MOSFET architecture has been proposed as a possible solution to allow the scaling of MOSFETs to the sub-30 nm regime, particularly due to its inherent resistance to short-channel effects. The use of lightly doped, or even undoped, channels means that such devices should be inherently resistant to random dopant induced fluctuations which will be one of the major obstacles to MOSF...

Analog and RF Performance Evaluation of Dual Metal Double Gate High-k Stack (DMDG-HKS) MOSFETs

Dual Metal Gate (DMG) technology was proposed to reduce the short channel effects (SCE’s) of double gate MOSFETs. But, DMG alone is not enough to rectify the problem of gate tunneling current due to thinning of oxide layer with device downscaling. So, the use of high-k dielectric as gate oxide is considered to overcome the gate tunneling effect. But, high gate dielectric thickness leads to high...

Intrinsic Fluctuations in Sub 10-nm Double-Gate MOSFETs Introduced by Discreteness of Charge and Matter

We study, using numerical simulation, the intrinsic parameter fluctuations in sub 10 nm gate length double gate MOSFETs introduced by discreteness of charge and atomicity of matter. The employed “atomistic” drift-diffusion simulation approach includes quantum corrections based on the density gradient formalism. The quantum confinement and source-to-drain tunnelling effects are carefully calibra...

Intrinsic Parameter Fluctuations in Decananometer MOSFETs Introduced by Gate Line Edge Roughness

In this paper, we use statistical three-dimensional (3-D) simulations to study the impact of the gate line edge roughness (LER) on the intrinsic parameters fluctuations in deep decananometer (sub 50 nm) gate MOSFETs. The line edge roughness is introduced using a Fourier synthesis technique based on the power spectrum of a Gaussian autocorrelation function. In carefully designed simulation exper...
