As transistors continue to shrink, complex physical effects, such as quantum effects intensify, making the design process increasingly costly, whether based on experiments or technology computer-assisted design (TCAD) simulations. To reduce the experimental and simulation resources consumed during the design process, we propose a device optimization framework based on neural network-enhanced Bayesian Optimization (BO). We target two Figures of Merit (FoMs) of Nanowire field-effect transistor (NWFET) devices as optimization objectives: subthreshold swing (SS) and on-state current (Ion). By improving the neural network to better fit the nonlinear mapping between the objective functions and input parameters, we effectively optimize device parameters while reducing the number of TCAD simulations. Experimental results show that compared to Bayesian optimization frameworks based on Gaussian Process (GP), Random Forest (RF) and Deep Networks for Global Optimization (DNGO), our neural network-based Bayesian optimization framework reduced the number of iterations by 19.3%, 42.7% and 60.3%, respectively.","PeriodicalId":13210,"journal":{"name":"IEEE Journal of the Electron Devices Society","volume":"13 ","pages":"456-463"},"PeriodicalIF":2.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11003089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A coupling phenomenon between hot-carrier injection (HCI) and negative bias temperature instability (NBTI) effects has been found at elevated temperatures, where HCI-induced self-heating effect (SHE) exacerbated the NBTI effects. Device degradation was found to be closely related to the waveform, frequency, and operating temperature. The quasi-static-approximation (QSA) model built with DC stress test data, was employed for device and circuit degradation predictions, and its limitations and applicability were discussed. Additionally, based on AC test data, the QSA model was used to simulate corrections for device and circuit degradation at corresponding frequencies. The results revealed over-predictions of degradation level by a time factor over 10.","PeriodicalId":13210,"journal":{"name":"IEEE Journal of the Electron Devices Society","volume":"13 ","pages":"270-277"},"PeriodicalIF":2.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10918946","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The period and width of the metal grating were adjusted at each pixel position according to CRAs, thereby improving the NIR sensitivity at sensor edges. The plasmonically diffracted light with angled chief ray was confined within the pixel photodiode. The photon confinement resulted in a significant improvement in absorption of approximately 37% or more, within an incident angle range of 30 degrees at a NIR wavelength of 940 nm and a silicon thickness of 3 μm.

The maximum lattice temperature (<inline-formula> <tex-math>$T_{max}$ </tex-math></inline-formula>) in the hafnium oxide (HfO2)/SiO2 structure is 391.953 K under the same current condition, whereas <inline-formula> <tex-math>$T_{max}$ </tex-math></inline-formula> is reduced to 360.941 K in the HfO2/Al2O3 structure, indicating improved thermal management.
