A novel multi deposition multi room-temperature annealing technique via Ultraviolet-Ozone to improve high-K/metal (HfZrO/TiN) gate stack integrity for a gate-last process

International Electron Devices Meeting (2010)

Lei Wu K. S. Yew D. S. Ang W.J. Liu T. T. Le

ALD HfZrO high-K fabricated by novel multi deposition multi annealing (MDMA) technique at room temperature in Ultraviolet-Ozone (UVO) ambient is systematically investigated for the first time via both physical and electrical characterization. As compared to the reference gate stack treated by conventional rapid thermal annealing (RTA) @ 600°C for 30 s (with PVD TiN electrode), the devices receiving MDMA in UVO demonstrates: 1) more than one order of magnitude leakage reduction without EOT penalty at both room temperature and an elevated temperature of 125°C; 2) much improved stress induced degradation in term of leakage increase and flat band voltage shift (both room temperature and 125°C); 3) enhanced dielectrics break-down strength and time-dependent-dielectric-breakdown (TDDB) life time. The improvement strongly correlates with the cycle number of deposition and annealing (D&A, while keeping the total annealing time and total dielectrics thickness as the same). Scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS) analysis suggest both oxygen vacancies (V _o ) and grain boundaries suppression in the MDMA treated samples are likely responsible for the device improvement. The novel room temperature UVO annealing is promising for the gate stack technology in a gate last integration scheme.

An efficient and thermally stable Cr³⁺-activated Y₂GdSc₂Al₂GaO₁₂ garnet phosphor for NIR spectroscopy applications

Dalton Transactions (2023)

Jihuan Xie Junhang Tian Lipeng Jiang Min Cao Weidong Zhuang

Near-infrared (NIR) spectroscopy realized by an NIR phosphor-converted light-emitting diode (pc-LED) as a light source has aroused considerable interest due to its numerous merits and widespread application scenarios. Nevertheless, developing NIR emitting phosphors with high performance is still the top priority. Here, we report a new Y2GdSc2Al2GaO12:Cr3+ (YGSAG:Cr3+) garnet phosphor, which demonstrates a broadband emission peaking at 754 nm with a full width at half maximum (FWHM) of around 120 nm in the range of 650-1200 nm. The YGSAG:0.08Cr3+ sample irradiated by blue light exhibits the most intense emission intensity, leading to a high absorption efficiency of 49.54%. In addition, compared with room temperature, the integrated PL intensity of the sample can still be maintained at 90.97% at 423 K. Benefitting from the outstanding optical properties, the as-manufactured NIR pc-LED device driven by a 100 mA current represents a high NIR output power of 35.14 mW and a photoelectric efficiency of 12.51%. These results verify that the as-synthesized YGSAG:Cr3+ phosphor possesses great potential for the applications of NIR spectroscopy.

A Novel Methodology to Predict Process-Induced Warpage in Advanced BEOL Interconnects

2022 IEEE International Reliability Physics Symposium (IRPS) (2023)

Y.H. Lin Chang‐Chun Lee Chan-Yu Liao Ming‐Hsien Lin Wu‐Chun Tu

Process-induced warpage caused by high-density interconnects in the back-end of line (BEOL) structure, may affect the performance and the reliability of the product during the packaging process. In this paper, a BEOL structure is used to develop a process-oriented simulation methodology to optimize the design and predict warpage. To reduce simulation time and obtain accurate predictions, the equivalent material method and equivalent residual stress are used in our proposed method. The layer-by-layer warpage predictions matched the measurement data.

Scalable Compliant Graphene Fiber-Based Thermal Interface Material with Metal-Level Thermal Conductivity via Dual-Field Synergistic Alignment Engineering

ACS Nano (2024)

Jiahao Lu Xin Ming Min Cao Yingjun Liu Bo Wang

High-performance thermal interface materials (TIMs) are highly desired for high-power electronic devices to accelerate heat dissipation. However, the inherent trade-off conflict between achieving high thermal conductivity and excellent compliance of filler-enhanced TIMs results in the unsatisfactory interfacial heat transfer efficiency of existing TIM solutions. Here, we report the graphene fiber (GF)-based elastic TIM with metal-level thermal conductivity via mechanical-electric dual-field synergistic alignment engineering. Compared with state-of-the-art carbon fiber (CF), GF features both superb high thermal conductivity of ∼1200 W m

Biogenesis and regulatory hierarchy of phased small interfering RNAs in plants

Plant Biotechnology Journal (2018)

Pingchuan Deng Sajid Muhammad Min Cao Liang Wu

Several varieties of small RNAs including microRNAs (miRNAs) and small interfering RNAs (siRNAs) are generated in plants to regulate development, genome stability and response to adverse environments. Phased siRNA (phasiRNA) is a type of secondary siRNA that is processed from a miRNA-mediated cleavage of RNA transcripts, increasing silencing efficiency or simultaneously suppressing multiple target genes. Trans-acting siRNAs (ta-siRNAs) are a particular class of phasiRNA produced from noncoding transcripts that silence targets in trans. It was originally thought that 'one-hit' and 'two-hit' models were essential for processing distinct TAS precursors; however, a single hit event was recently shown to be sufficient at triggering all types of ta-siRNAs. This review discusses the findings about biogenesis, targeting modes and regulatory networks of plant ta-siRNAs. We also summarize recent advances in the generation of other phasiRNAs and their possible biological benefits to plants.

Monodomain Liquid Crystals of Two-Dimensional Sheets by Boundary-Free Sheargraphy

Nano-Micro Letters (2022)

Min Cao Senping Liu Qing Zhu Ya Wang Jingyu Ma

Eliminating topological defects to achieve monodomain liquid crystals is highly significant for the fundamental studies of soft matter and building long-range ordered materials. However, liquid crystals are metastable and sensitive to external stimuli, such as flow, confinement, and electromagnetic fields, which cause their intrinsic polycrystallinity and topological defects. Here, we achieve the monodomain liquid crystals of graphene oxide over 30 cm through boundary-free sheargraphy. The obtained monodomain liquid crystals exhibit large-area uniform alignment of sheets, which has the same optical polarized angle and intensity. The monodomain liquid crystals provide bidirectionally ordered skeletons, which can be applied as lightweight thermal management materials with bidirectionally high thermal and electrical conductivity. Furthermore, we extend the controllable topology of two-dimensional colloids by introducing singularities and disclinations in monodomain liquid crystals. Topological structures with defect strength from - 2 to + 2 were realized. This work provides a facile methodology to study the structural order of soft matter at a macroscopic level, facilitating the fabrication of metamaterials with tunable and highly anisotropic architectures.

Large photoelectric-gating effect of two-dimensional van-der-Waals organic/tungsten diselenide heterointerface

npj 2D Materials and Applications (2018)

Zhi Cai Min Cao Zhepeng Jin Kongyang Yi Xiaosong Chen

Abstract Photo- or photoelectric-gating modulation is a promising strategy for high-performance photodetectors, which amplifies photoresponsivity by long-lived trapped charges at the interface. However, the performance is normally limited by the uncontrollable trapping process. Here, we develop a large photoelectric-gating, which enhances interfacial charge trapping process by a van-der-Waals interface with an electric-gating tunable energy barrier in the band alignment. By synergy of photo-gating and electric-gating effects, responsivity and detectivity of 1,4-bis(4-methylstyryl)benzene/tungsten diselenide (WSe 2 ) increase by 25-fold and 3-fold to 3.6 × 10 6 A/W and 8.6 × 10 14 Jones. High-quality two-dimensional van-der-Waals interface is of great importance. Sufficient supply of gas-phase molecules in physical vapor deposition is pivotal to obtain such interface between organic crystal and WSe 2 . As an application, an electric-gating switchable photodetector has been developed, showing great potential of this strategy not only in high-performance photodetectors but also in new photoelectrical devices.

Intercalated Graphene as Next Generation Back-end-of-Line Conductors

2022 International Electron Devices Meeting (IEDM) (2023)

S. W. Li Y.C. Chan Chen Hsu Sen-Yeu Yang K. Y. Liao

Research on adopting graphene nanoribbons for conductor application has been at the forefront for over a decade. However, the exhibited high film and contact resistivities with metals have been prohibiting so far the practical realization of graphene conductors. In this work we propose a symbiotic graphene intercalation and edge-contact architecture to reduce both film and contact resistivities of graphene. Our results show two-fold achievements: 1) a film resistivity lower than Cu below 150 Å thickness, and 2) four orders reduction on specific contact resistivity. Furthermore, a comprehensive simulation workflow is proposed based on density functional theory to screen for novel intercalant materials not yet explored. The model points to the discovery of n-type metals as potentially promising candidates to further improve intercalated graphene's electrical properties.
