Compared to the conventional double-trench MOSFET (DT-MOS), simulation results indicate that the nHJ-TMOS significantly reduces the reverse on-state voltage drop <inline-formula> <tex-math>$(V_{mathrm { R_on}})$ </tex-math></inline-formula> from 3.7 to 1.6 V, due to the integration of the N+-PolySi/SiC heterojunction diode (nHJD), which features a low barrier height of ~0.70 eV. By reducing the depth of the gate trench, nHJ-TMOS effectively mitigates the electric field crowding effect at the corners of the gate oxide, obtaining a low electric field of only 2.1 MV/cm. Besides, this shallow gate trench reduces the gate-to-drain capacitance <inline-formula> <tex-math>$(C_{mathrm { GD}})$ </tex-math></inline-formula> by 30.9%. Moreover, due to unipolar conductivity of the nHJD, the reverse recovery charges <inline-formula> <tex-math>$(Q_{mathrm { rr}})$ </tex-math></inline-formula> of nHJD is reduced by 26.7% and 59.5% under 25°C and 175°C, respectively.

This paper studies how different aspects of measurement data can be used best. Specifically, the reliability of the solder joint of LED packages is predicted based on Transient Thermal Analysis and Scanning Acoustic Microscopy data from a large measurement campaign. The impact of using full temporal information vs measurements at individual datapoints is investigated as well as the benefit of including the SAM data, and different ways of presenting the TTA information, either as a full curve or as expert-selected features. The impact of formatting categorical information of solder and LED package type as one-hot encoding or using embeddings is considered. Finally, the performance for Pass/Fail predictions of the best identified model with a model architecture developed on a similar dataset is compared. We identified the most relevant sources of information for predicting the behavior and the best format for the data, which helps guide the choice for future model architectures.","PeriodicalId":448,"journal":{"name":"IEEE Transactions on Device and Materials Reliability","volume":"26 1","pages":"157-166"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11250977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148511508","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}

Over the last decade, electron beam induced resistance change (EBIRCH) has been the primary nanoProbing method for isolating shorts in circuits and device structures. However, its material-dependent thermal sensitivity, dual-probe requirement, and biasing-induced failure risks compromise reliability during root cause analysis. This study demonstrates how electron beam induced current (EBIC) significantly improves failure analysis (FA) reliability in logic devices through superior spatial resolution and predictable signal generation. By leveraging its reliance on electron-hole pair generation in a pn junction, EBIC eliminates uncontrolled Seebeck effects, reduces sample blowout risks, and enables single-probe operation without biasing. EBIC is versatile and more easily controlled by the e-beam parameters. The method was reproduced on several different samples with improved FA success rate and quality, and reduced turnaround time compared to EBIRCH.","PeriodicalId":448,"journal":{"name":"IEEE Transactions on Device and Materials Reliability","volume":"26 1","pages":"194-200"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148511917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, further scaling is constrained by the limitations of planar high-voltage (HV) pass transistors used for WL drivers, which suffer from gate-induced drain leakage (GIDL), punch-through, and poor short-channel control. In this work, we propose the buried channel array transistor (BCAT) as a scalable alternative. While widely adopted in DRAM, its application as an HV pass transistor in NAND Flash remains unexplored. After calibration with measured planar HV transistor data, the same physical parameters were applied to BCAT structures in TCAD simulation to isolate geometry-dependent effects. Through physics-based TCAD analysis, we evaluate the structural and electrostatic suitability of BCAT for HV pass transistor applications. BCAT shows improved off-state robustness due to its extended effective channel and confined electric field distribution, but suffers from increased threshold voltage (<inline-formula> <tex-math>$V_{mathrm {T}}$ </tex-math></inline-formula>) shift induced by body effect. To mitigate the body effect, we propose vertical channel length and body doping concentration as a design knob to balance leakage suppression and <inline-formula> <tex-math>$V_{mathrm {T}}$ </tex-math></inline-formula> control.

By eliminating PTS doping, the LTG avoids drawbacks such as increased band-to-band tunneling and random dopant fluctuations while maintaining strong gate-to-channel electrostatics through a layered trench design. We benchmark the LTG against conventional leakage control methods—PTS, bottom dielectric isolation (BDI), local BDI (LBDI), and trench gate (TG)—under realistic fabrication variations, particularly a 6 nm source/drain over-etch. Under these conditions, the PTS structure suffers a 2,840-fold increase in off-current and a <inline-formula> <tex-math>$3.84times 10^{{-3}}$ </tex-math></inline-formula>-fold reduction in on/off ratio, whereas the LTG shows only 21.5-fold and <inline-formula> <tex-math>$4.69times 10^{{-2}}$ </tex-math></inline-formula>-fold changes, respectively, demonstrating significantly improved robustness. A 3-stage ring oscillator simulation reveals that the LTG achieves 1.9% shorter delay and 2.4% lower dynamic power under identical conditions.
