Local Variability Evaluation on Effective Channel Length

Extracted with Shift-and-Ratio Method

IEEE TED, vol. 67, no. 11, pp. 4662-4666, Nov. 2020

doi: 10.1109/TED.2020.3017178

Abstract: In this study, the local variation of the effective channel reduction parameter (ΔL=Lm−Leff) of a MOSFET is extracted by means of the traditional shift-and-ratio (SAR) method. ΔL is then correlated with the threshold voltage difference (ΔVTH) between the device under test (DUT) and the reference device. It is demonstrated that there exists an optimal VG range for extracting reliable values of L through the SAR method. Statistical data analysis shows that for R≈ (Llong/Lshort)≈25, better results are achieved since the value of σ(ΔL) varies typically as the reciprocal 1/√ W. The test structure used in this work is a Kelvin-based 2-D addressable MOSFET matrix implemented in 180-nm bulk CMOS technology. The sample space is of 2304 devices divided into nine subgroups of 256 same size closely placed nMOSFETs.

ASCENT project

Applications and Systems-driven Center for Energy-Efficient integrated Nano Technologies

The Mission of the ASCENT Center is to transcend the current limitations of high-performance transistors confined to a single planar layer of integrated circuit by pioneering vertical monolithic integration of multiple interleaved layers of logic and memory, by demonstrating beyond-CMOS device concepts that combine processing and memory functions, heterogeneously integrating functionally diverse nano-components into integrated microsystems and by demonstrating in-memory compute kernels to accelerate future data-intensive at-scale cognitive workloads.

Researchers at ASCENT pursue four areas of technology including three-dimensional integration of device technologies beyond a single planar layer (vertical CMOS); spin-based device concepts that combine processing and memory functions (beyond CMOS); heterogeneous integration of functionally diverse nano-components into integrated microsystems (heterogeneous integration fabric); and hardware accelerators for data intensive cognitive workloads (merged logic-memory fabric).

ASCENT is one of six research centers funded by the SRC’s Joint University Microelectronics Program (JUMP), which represents a consortium of industrial participants and the Defense Advanced Research Projects Agency (DARPA). Information about the SRC can be found at https://www.src.org/.

ASCENT is a collaboration of the following Universities:
