The 3-D heterogeneous integration technology of microsystem is the best technical means to achieve higher integration, higher performance and higher working frequency of radio frequency ( RF) electronic *** microsystem integration technology is categorized into three main types based on the packaging substrate: silicon-based,ceramic-based,and resin-based. In this work, the principle of RF microsystem integration technology is demonstrated in detail, and the process routes and characteristics of different packaging structures are clarified. Moreover, through the multi-dimensional comparison of different packaging structures, the application conditions of specific packaging structures are obtained. According to the comprehensive evaluation, the resin-based embedded chip package shows outstanding potentials in RF performance, integration capability, batch production capability and process cost. However, there are three shortcomings that limit its application in RF microsystems: Firstly, in terms of the universality of RF chips, metal grounding on the back of RF chips cannot be realized by this packaging, and special design of RF chips is required. At present, however, the universal chip with gold back grounding on the market cannot meet the requirements of the packaging process. Secondly, because of the high cost of customized chips, this packaging process is not suitable for small-scale production. Thirdly, the resin-based package does not have the sealing function, thus reliability of the product still needs to be verified. Ceramic-based RF microsystems do not require customized chips and have advantages in chip versatility compared to resin-based systems, with integration capabilities comparable to resin-based systems. However, its batch production capacity is much lower than resin based. In contrast, the silicon-based embedded chip package is as excellent as the resin-based products in chip versatility, RF performance, integration capability, batch production

Cross-organizational process mining (coPM) with data from at least two organizations assists cooperating organizations in optimizing their operations by enabling an in-depth and continuous process analysis. As coPM faces unique challenges and is rarely applied, we followed a design science-based approach and developed a three-step extension to the PM project methodology to integrate data across organizational boundaries. Each organization first creates a local event data knowledge graph (KG). Second, a trusted third party integrates all local KGs into a global KG. Third, a federated event log and process knowledge are retrieved for coPM analysis. Overall, we present the first version of a methodology to support data integration for coPM, thereby assisting researchers and practitioners in unlocking value potentials from coPM analysis.

The rapid development of musical AI technologies has expanded the creative potential of various musical activities, ranging from music style transformation to music generation. However, little research has investigated how musical AIs can support music therapists, who urgently need new technology support. This study used a mixed method, including semi-structured interviews and a participatory design approach. By collaborating with music therapists, we explored design opportunities for musical AIs in music therapy. We presented the co-design outcomes involving the integration of musical AIs into a music therapy process, which was developed from a theoretical framework rooted in emotion-focused therapy. After that, we concluded the benefits and concerns surrounding music AIs from the perspective of music therapists. Based on our findings, we discussed the opportunities and design implications for applying musical AIs to music therapy. Our work offers valuable insights for developing human-AI collaborative music systems in therapy involving complex procedures and specific requirements.

This work describes two designed and fabricated circuits for power device integration in 650 V e-mode GaN-on-Si technology and gives their main measured characteristics. The first circuit is a voltage reference designed to compensate process, voltage and temperature (PVT). The advantage of this circuit over state-of-the-art circuits is its performance of regulation, low current consumption and surface required (only 100 mu m x 60 mu m in the first prototype built). The second circuit is a zero-crossing current detector that is also designed to be insensitive to process variations. It exhibits stable static characteristics and bandwidth observed in simulation of more than 10 MHz. The convenience of this circuit is its simplicity because no differential amplifier is used to make a comparison. Both circuits are designed to be integrated with power transistors in GaN technology to be used in ACF or other topologies capable of switching at 650 V.

This paper presents the design, simulation, analysis and characterization of a heterogenous 3D integration approach for miniaturization of RF front-end modules. The 3D integrated stack consists of two dies using different technologies. The first die is a low-noise amplifier (LNA), designed and fabricated in 130nm 8SW RF SOI Global Foundries technology. The second die is a duplexer built using Qorvo's BAW technology. The first die is used as a base on which the second die is mounted. To achieve this integration a redistribution layer (RDL) has been designed and built on the backside of the first die. through silicon vias (TSV) have also been designed and built to allow the top die to be routed and interconnected to the bottom die as well as to the outside world. The final size of the integrated module is 1x1.4x0.45 mm(3). This paper discusses in detail the designprocess of the module, the simulation models with the associated simulation results. It also presents measurement results obtained from a test vehicle design to extract the parasitics and equivalent circuit of the TSV through the SOI wafer. The signal losses measured through the test structures, that emulates the 3D stack environments, are below 0.2dB at 2GHz. These results are promising and give us confidence for the final functional module testing.

Chiplets integration offers a compelling value proposition for yield improvement, IP reuse, performance and cost optimization. Various advanced packaging technologies such as 2.5D Si TSV interposer, Fanout RDL organic interposer and 3D hybrid bonding have been deployed for chiplets and system heterogeneous integrations. Meanwhile, integrating multiple chiplets with diverse functions into a single package has also created a demand for advanced packages with higher den sity interconnects and larger footprint body sizes. How to optimize the layout to get the optimal performance among th e chiplets has become very critical. In addition, high density and complex connectivity in advanced packaging cause more challenges by using traditional EDA tools for packaging design and assembly manufacturing valid ation. Furthermore, the die-to-die interconnects for chiplets integration are usually proprietary links from different customers, thu s also create more design boundaries and limit the adoption of advanced packaging technology. In this paper, a new chip-to-package hybrid design platform for chiplets integration using advanced packaging technology was introduced. The design platform was utilized to complete the routings of ultra-high density I/O in 2.5D Si interposer and Fan-Out RDL organic interposer. Compared with the traditional package level design platform, the new hybrid design platform had reduced the design cycle time and improved design accuracy. Additionally, this platform had leveraged and validated the open standard Die-to-Die interconnects through the UCle (Universal Chiplet Interconnect Express) ecosystem. Good electrical performance was achieved and met the requirements under the pin speed of 32Gbps for both fanout RDL organic interposer and 2.5D Si TSV advanced packaging technologies. Furthermore, a new packaging processdesign kit (PDK) had been developed to provide IC and system designers with advanced packaging design rule s. Finally, this paper elaborated
