We present a quasi-delay-insensitive (QdI) circuit designed to provide a correct-by-construction cross-die link in a 3d augmented reality system-on-chip (SoC) in a 7nm hybrid-bonding face-to-face wafer bonded process. The circuit can operate at sub-threshold voltages, down to 0.235V, with a minimum energy point of 0.141pJ/B at 0.45V. Silicon measurements in 7nm technology demonstrate the circuit's ability to cope with delay variations, which are exacerbated in sub-threshold voltages, and to reach minimum energy voltage, which is not possible in equivalent synchronous links of the SoC.

3dintegration is increasingly gaining interest for a wide range of applications such as CMOS Image Sensor, dRAM and High Performance Computing. Low temperature hybrid bonding (< 250 degrees C) is more and more demanded by the industry to reduce the thermal budget of sensitive chips integration, or heterogeneous integrations with glass substrate for instance. This study investigates the effect of reducing the annealing temperature in direct hydrophilic wafer-to-wafer hybrid bonding on the morphology of the bonding interface in relation to the electrical results. This paper demonstrates the possibility of realizing a Cu-SiO2 hydrophilic direct wafer-to-wafer (W2W) hybrid bonding with a 5 mu m pitch interconnections, with a low temperature annealing (between 100 degrees C and300 degrees C).

Recent chip integration processes enable 3d stacking of multiple active dice in the same package, offering higher logic density, lower power consumption, and significant die-to-die bandwidth. Field-programmable gate arrays (FPGAs) can benefit from 3d chip integration either by stacking multiple homogeneous FPGA fabrics to increase logic capacity or by integrating with other heterogeneous application-specific integrated circuits (ASICs). This opens up a myriad of research questions and interrelateddesign choices. However, we lack the tools necessary to model these 3d reconfigurable devices and quantitatively explore their vast design space. In this work, we enhance existing FPGA architecture exploration tools and build new ones to address this gap, with a cross-stack focus on circuit-level fabric modeling, 3dintegration considerations, system-level architecture, and computer-aideddesign (CAd) tools. We extend the RAd-Gen framework by integrating an upgraded version of the COFFE automatic transistor sizing tool that supports 7 nm FinFETs with a more accurate, metal-aware area model for newer process technologies. We also implement new tools in RAd-Gen for modeling the inter-die connections and power distribution networks of 3d architectures. In addition, we introduce a new version of the Versatile Place & Route (VPR) tool that can model 3ddevices, with enhancements to its architecture description language and its placement and routing engines. Finally, we showcase the capabilities of our enhanced tools by modeling and evaluating both homogeneous and heterogeneous 3d reconfigurable devices.

This paper presents a novel copper pillar based microfluidic integration within a high performance SiGe BiCMOS technology. An embedded calorimetric thermal flow sensor as key microfluidic component has been implemented based on a standard BiCMOS BEOL metallization. The integration concept has been analyzed in terms of technological development as well as it has been established via microfluidic characterization of the designed flow meter sensor. The BiCMOS microfluidic technology platform will be utilized as a sensor platform for sub-THz microfluidic sensor applications.

Monocular 3d object detection plays a critical role for autonomous driving and robot navigation. The lack of depth information in a single 2d image, makes this task highly challenging, necessitating a substantial amount of data to achieve high performance. To minimize the annotation cost, active learning has been employed effectively in various vision tasks. Addressing this challenge, we propose a novel strategy calledintegration of Informativeness anddiversity for Active Learning (IIdAL) for monocular 3d object detection. In the first stage, the candidate samples are selected based on interaction of informativeness and image-level diversity. In the second stage, the final samples are selected based on the diversity between the candidate set and the labeled set to eliminate redundant samples. Furthermore, we introduce a novel initialization strategy to prevent "cold-start" problem. Our framework is model-agnostic requiring no modifications to the detector architecture, and can be seamlessly applied to other monocular 3d object detectors. Extensive experiments on the KITTI dataset demonstrate the effectiveness of IIdAL over baseline methods. Our approach achieves a 20% reduction in annotation costs and outstanding performance, particularly when using less than 50% of the data.

This paper presents a study of increased information storage capabilities of single memory cell of new 3ddesign. Memory was designed for integration with VeSTIC (Vertical Slit Transistor-based Integrated Circuits) technology, to increase the circuit density to effectively use available space. This memory operates in relative environment, with control voltage not exceeding 9 V. Test simulations of memory cell indicate, that it has the capability to hold even more than 2 bits of information data. This design opens new possibilities for integration of advanced integrated circuits with dedicated non-volatile memory in a single chip with maximum device density.

Open-vocabulary 3d instance segmentation transcends traditional closed-vocabulary methods by enabling the identification of both previously seen and unseen objects in real-world scenarios. It leverages a dual-modality approach, utilizing both 3d point clouds and 2d multi-view images to generate class-agnostic object mask proposals. Previous efforts predominantly focused on enhancing 3d mask proposal models;consequently, the information that could come from 2d association to 3d was not fully exploited. This bias towards 3ddata, while effective for familiar indoor objects, limits the system's adaptability to new and varied object types, where 2d models offer greater utility. Addressing this gap, we introduce Zero-Shot dual-Path integration Framework that equally values the contributions of both 3d and 2d modalities. Our framework comprises three components: 3d pathway, 2d pathway, anddual-Path integration. 3d pathway generates spatially accurate class-agnostic mask proposals of common indoor objects from 3d point clouddata using a pre-trained3d model, while 2d pathway utilizes pre-trained open-vocabulary instance segmentation model to identify a diverse array of object proposals from multi-view RGB-d images. In dual-Path integration, our Conditional integration process, which operates in two stages, filters and merges the proposals from both pathways adaptively. This process harmonizes output proposals to enhance segmentation capabilities. Our framework, utilizing pre-trained models in a zero-shot manner, is model-agnostic anddemonstrates superior performance on both seen and unseen data, as evidenced by comprehensive evaluations on the ScanNet200 and qualitative results on ARKitScenes datasets.

In recent years, automation technologies in the medical field, such as surgical robots and rehabilitation robots, have become commonly used. In the field of regenerative medicine, automation technologies are being developed to create the scaffolds for tissue formation and the organs. The challenges of implementing these technologies include high installation costs, hiring engineers, and installation space. The goal of this study is to develop 3d printing technology of a scaffold for the tissue formation in clinical sites, aiming to reduce medical doctors' workloads. In this paper, we report on the movement performance and cleanliness of our arm-type 3d printer. We analyze the vibration characteristics of the arm-type 3d printer to ensure stable 3d printing. We also designed a cover to eliminate dust emissions from the arm-type 3d printer and measure its cleanliness. Experimental results show our arm-type 3d printer is enough specification to be installed in a clean bench at a clinical site.

We propose the use of the USB protocol to increase the convenience and expandability of adding features to 3d printers. To implement this, we developed a Human Interface device (HId) and an Octoprint plug-in for feature addition. This approach has made it easier to add features to existing 3d printers via USB and has confirmed the improved expandability through compatibility with various 3d printers.
