Performance Analysis of Gate Stack DG-MOSFET for Biosensor Applications Saradiya Kishor Parija, Sanjit Kumar Swain, Sudhansu Mohan Biswal, Sarosij Adak, Pradipta Dutta Silicon, 2022 In this paper the performance of gate stack metal oxide semiconductor field effect transistor (MOSFET) is investigated with respect to different bio molecules for application as biosensor device. In order to beat the limits of short channel effects (SCEs) the double gate stack MOSFET has been preferred as the proposed device. For biosensor application, dielectric modulation technique has been chosen and effect of different bio molecules like protein, biotin, streptavidin, APTES, etc. are studied to verify the sensitivity as a biosensor for this proposed device. The sensitivity parameter and analog/Rf parameter have been studied for different bio-molecules and a comparative result has been established. The sensitivity of bimolecules located in the cavity side by the oxide region is observed in the variation of threshold voltage and also different analog and RF parameters which can be used for future application in the area of medical science. Two oxide layer one is high k(HfO 2 ) and low k(SiO 2 ) has been used for stacking. For simulations, 2D Sentrausu TCAD simulator has been used.
Comparison Study of DG-MOSFET with and without Gate Stack Configuration for Biosensor Applications Saradiya Kishor Parija, Sanjit Kumar Swain, Sarosij Adak, Sudhansu Mohan Biswal, Pradipta Dutta Silicon, 2022 In this Paper, we have studied and compared the performance of two different configurations of simulation model advanced MOSFET devices which can be used for biosensor application. The bio-molecules like protein, biotin, streptavidin, APTES, etc., undergo label free electrical detection with the help of dielectrical modulation technique in order to overcome the limitations of short channel effect in a more efficient way. The bio-molecules trapped inside the cavity region change the electrical parameters of the MOSFET. Biosensors based on MOSFETs have certain issues, like short channel effects (SCEs) and problems related to scaling and power supply. Therefore the proposed device is better withstand to SCEs and can be consider as an alternative for biosensing applications. For channel material, silicon is used for both the configurations i.e. with stack and without stack model and we have also studied the performance of the device based on the analog as well as RF parameters by considering the protein as bio-molecule in the cavity. Two different oxide materials are used to design the device structure such as HfO2 (K = 25) and SiO2 (K = 3.9) and for simulation purpose the 2D Sentrausu TCAD simulator has been used. The sensing capability of this proposed dielectric modulated device can be applicable for IOT based applications. They can also be uses in health IOT systems for medical research applications and as bio chip sensor in wearable device so as to study the protein content of the human body.
Comparative study on Analog RF Parameter of InAlN/AlN/GaN Normally off HEMTs with and without AlGaN back barrier Nisarga Chand, Sanjit Kumar Swain, Sudhansu Mohan Biswal, Angsuman Sarkar, Sarosij Adak Proceedings of 4th International Conference on 2021 Devices for Integrated Circuit Devic 2021, 2021 In this work, we have made a relative assessment of lattice-matched In0.17Al0.83N/AlN/GaN normally off HEMT device with AlGaN back-barrier (BB) and without back-barrier by using device simulator. The utility of AlGaN BB on the said E-HEMT relaxes the channel, which reduces the short channel effects. It also reduces the total gate capacitance and simultaneously improves the cut- off frequency. The numerical modelings are done by the 2Dimenssional TCAD by means of HD mobility and matched with the previously accepted experimental result. Different device parameters are analyzed and compared with BB and without BB with the help of the numerical modeling. AlGaN back-barrier has further benefits in device parameters with comparison to without back-barrier i.e. less total gate capacitance and higher cut-off frequency. These outcomes prove the utility of proposed BB in such E-Mode GaN HEMTs can be a substitute way out in support of high power along with high-frequency purposes.
Study of Linearity Performance of Graded Channel Gate Stacks Double Gate MOSFET with Respect to High-K Oxide Thickness Sanjit Kumar Swain, Satish Kumar Das, Sarosij Adak Silicon, 2020 In this paper a double gate MOSFET having non uniform channel doping with gate stack structure is explored to study the linearity analysis. The extractions of linearity parameters confirm the novelty of the device and also enable us to achieve better the analog/RF applications. This promising device has an advantage of showing higher cut-off frequency, reduced DIBL, better gate oxide reliability and limiting the effects of parasitic bipolar phenomenon. In this paper we have studied the detail analysis of important linearity parameters of this proposed device with respect to change in high K oxide thickness (t oxh ) to have clear ideas on different linearity parameters like VIP2, VIP3, IIP3 and IMD3 and their variations. The simulated results validate that the change in t oxh of this device plays a significant role on improving the linearity performance and there by careful optimization of this parameters can infer achieving better and reliable analog/linearity performances for SOC applications.

Result:: The simulation results revealed that the performances of the device are sensitive to both the oxide materials and it was also inferred that gate stack technology gave a better performance over SiO2 oxide layer. Conclusion:: These results have significant effects in analog, RF and linearity operations. In this work, computer aided design (TCAD) simulations by 2D ATLAS, Silvaco International have been used.
Impact of high-K dielectric materials on performance analysis of underlap in 0. 1 7 Al 0. 8 3 N/GaN DG-MOSHEMTs Sarosij Adak, Sanjit Kumar Swain Nano, 2019 This work systematically investigated the effect of high-[Formula: see text] oxide materials on the performance of InAlN/GaN heterostructure underlap double gate (DG) MOS-HEMTs by considering 2D Sentaurus TCAD simulation. During the course of simulation, hydrodynamic mobility model was implemented and the obtained results were used for validating the model with the previously published experimental results. Different device performance parameters are thoroughly studied for different high-[Formula: see text] oxide materials by performing extensive simulations. It is verified that short channel effects (SCEs), key analog and RF figures of merits parameters and [Formula: see text]th improved with an increase in the value of high-[Formula: see text] oxide material. Moreover, it is also revealed that there is a significant growth in the values of key analog and RF figures of merits with respect to high-[Formula: see text] values. This analysis suggested that use of a suitable value of high-[Formula: see text]-valued oxide material in InAlN/GaN heterostructure underlap DG MOS-HEMTs can be one of the alternatives for future high speed and microwave applications.
Effect of AlGaN Back Barrier on InAlN/AlN/GaN E-Mode HEMTs Sarosij Adak, Nisarga Chand, Sanjit Kumar Swain, Angsuman Sarkar Proceedings of 3rd International Conference on 2019 Devices for Integrated Circuit Devic 2019, 2019 This paper reports the effect of AlGaN back barrier on the performance of lattice matched In0.17Al0.83N/AlN/GaN Recess Gate E HEMT Device. The use of AlGaN back barrier on this device relaxes the GaN channel, which in turn limits the SCEs. Moreover reduced the leakage current through gate (Ig) and simultaneously improves carrier confinement and off state breakdown voltage. The numerical modeling are carried out with the help of 2D Sentaurus TCAD simulator using Hydrodynamic model, which is standardized with respect to already published fabricated results. Different performance parameters are studied using the simulations and a wide comparison was done with and without considering AlGaN back barrier (BB). Addition of AlGaN BB has added benefits in performance parameters w.r.t without BB i.e. threshold voltage raised to 0.93 volt with respect to 0.75 volt, drop in DIBL from 100mv/V to 36mv/V and substantial reduction in gate leakage current. These results reveal that use of AlGaN BB in such devices can be an alternative solution for high power and high frequency switching applications.
