This work develops a broadband dual-component magnetic probe with a new structural design, tailored for electromagnetic interference (EMI) diagnostic applications. Unlike the conventional dual-component magnetic probes that measure the ${H} _{x}$ and ${H} _{y}$ field components, the proposed probe employs a new detection architecture capable of simultaneously measuring two orthogonal ${H} _{y}$ and ${H} _{z}$ field components. The probe structure comprises a new detection architecture, a pair of striplines, two ground planes, and a pair of SubMiniature version A (SMA) connectors. This configuration enables concurrent measurement of the ${H} _{y}$ and ${H} _{z}$ field components. To validate the design, the proposed probe was fabricated on a four-layer printed circuit board (PCB), evaluated through simulations using high-frequency electromagnetic simulation software, as well as measurements via a self-developed near-field measurement system with two distinct calibration kits (microstrip line and slot-line). Both simulated and experimental results demonstrate that the probe can not only have a wider operational bandwidth ($4sim 15$ GHz) but also realize simultaneous measurement of two orthogonal ${H} _{y}$ and ${H} _{z}$ field components.

This letter proposes a slow wave structure based on inductive-loading and applies it to the design of a miniaturized power divider. By adopting the capacitance and inductive-loading technology, the slow wave transmission line has a large slow wave coefficient. The proposed slow wave transmission line is based on the hybrid integrated suspended line (HISL) platform. The overall structure is a multilayer structure. The core layer slow wave structure is based on double-sided printed circuit board (PCB) circuit processing, and the remaining four layers are metal boards. The overall structure has good mechanical strength and the advantage of self-packaging based on multilayer. The designed slow wave power divider has a central operating frequency of 0.7 GHz and a circuit area of $13.49times 12.06$ mm, i.e., $0.036lambda $ g $times 0.033lambda $ g, where $lambda $ g is the guided wavelength at the center frequency.

This study explores the potential of SiCN films as a low-temperature alternative to SiO2 insulators for hybrid bonding in 3-D integration. SiCN films were deposited at $180~^{circ }$ C and $350~^{circ }$ C to investigate the effects of deposition temperature and composition on bonding performance. By optimizing precursor flow rates, we tailored the film properties, enhancing Si dangling bonds crucial for bonding. To achieve ultralow-temperature bonding below $100~^{circ }$ C, O2 plasma and potassium hydroxide (KOH) surface treatments were employed, significantly improving bonding interfaces by increasing Si-OH groups on the surface. Our results demonstrate that SiCN films deposited at low temperatures can achieve bonding characteristics comparable to those of high-temperature films. The enhanced bonding performance is attributed to surface treatments that mitigate hydrogen content and promote Si-OH formation. The low-temperature bonding capabilities of SiCN contribute to reducing thermal budgets, preventing device degradation, and advancing 3-D integration and hybrid bonding technologies for next-generation semiconductor applications.

A novel low-temperature wafer-level hybrid bonding technique using metal microbumps (Cu/SnAg) and nonphotosensitive dry films has been developed and investigated. The bonding process is conducted at low temperatures: $160~^{circ }$ C for the dry film and within the range of $260~^{circ }$ C–$280~^{circ }$ C for the microbumps. The microbumps are fabricated using conventional electroplating, while patterning of the nonphotosensitive dry film is achieved through laser ablation, bypassing the need for traditional lithography. Furthermore, optimizing the thickness of the microbumps, the opening dimensions of the dry film, the maximum bonding pressure, and the bonding temperature has enabled the development of a stepped control profile, which allows a seam-free bonding interface between the microbumps and the dry films. For demonstration, superior interconnect performance with an average tensile strength of approximately 8.11 MPa is achieved. The nonphotosensitive dry film exhibits low transmission loss when applied to glass packaging due to its low dielectric constant and dissipation factor. Consequently, the proposed hybrid bonding technique provides a highly cost-effective and promising approach for future multilayer glass/polyimide (PI) radio frequency (RF) 3-D integration.
研究了一种利用金属微凸点（Cu/SnAg）和非光敏干膜的低温晶圆级杂化键合技术。结合过程在低温下进行：$160~^{circ}$ C用于干膜，$260~^{circ}$ C - $280~^{circ}$ C用于微凸起。微凸起是用传统的电镀方法制造的，而非光敏干膜的图案是通过激光烧蚀来实现的，绕过了传统光刻的需要。此外，优化微凸点的厚度、干膜的开口尺寸、最大键合压力和键合温度，使微凸点和干膜之间形成无接缝的键合界面成为可能。作为验证，该材料具有优异的互连性能，平均抗拉强度约为8.11 MPa。非光敏干膜由于介电常数和耗散系数较低，应用于玻璃封装时具有较低的传输损耗。因此，所提出的混合键合技术为未来多层玻璃/聚酰亚胺（PI）射频（RF）三维集成提供了一种极具成本效益和前景的方法。

There is a critical need to understand the optimal process conditions and pad design for hybrid bonding at progressively finer pitches. The finite element method (FEM) analysis is a valuable approach for elucidating the bonding mechanism and predicting the bonded area. In this study, we investigated hybrid bonding using FEM analysis to study bonding mechanisms and suggest optimal design strategies. Models were constructed for sub-micrometer copper pads with silicon carbonitride (SiCN) as the dielectric film at the bonding interface, with variations in copper pad dimensions and dishing depth. The postbond annealing process was simulated with different annealing temperatures. The results show that high annealing temperatures and low chemical mechanical polishing (CMP) dishing depths promote sufficient pad expansion to achieve complete copper-to-copper bonding, which is consistent with established observations in the field. Furthermore, the study highlights a strong dependence of the bonded area on the copper pad dimensions, emphasizing the need for proper optimization of pad dimensions. In particular, copper bonding was highly sensitive to pad thickness and aspect ratio. As the pad thickness increased, thermal expansion increased, resulting in a larger bonded area. For all pad thicknesses, maximum thermal expansion occurred at an aspect ratio of approximately 0.4. Therefore, a specific diameter range was identified where the maximum bonded area could be achieved for a given pad thickness.
