The electronics packaging community strongly believes that Moore’s law will continue for another few years due to recent technological efforts to build heterogeneously integrated packages. Heterogeneous integration (HI) can be at the chip level (a single chip with multiple hotspots), in multi-chip modules, or in vertically stacked three-dimensional (3D) integrated circuits. Flux values have increased exponentially with a simultaneous reduction in chip size and a significant increase in performance, leading to increased heat dissipation. The electronics industry and the academic research community have examined various solutions to tackle skyrocketing thermal-management challenges. Embedded cooling eliminates most sequential conduction resistance from the chip to the ambient, unlike separable cold plates/heat sinks. Although embedding the cooling solution onto an electronic chip results in a high heat transfer potential, technological risks and complexity are still associated with the implementation of these technologies and with uncertainty regarding which technologies will be adopted. This manuscript discusses recent advances in embedded cooling, fluid selection considerations, and conventional, immersion, and additive manufacturing-based embedded cooling technologies.

Subwavelength manipulation of light waves with high precision can enable new and exciting applications in spectroscopy, sensing, and medical imaging. For these applications, miniaturized spectrometers are desirable to enable the on-chip analysis of spectral information. In particular, for imaging-based spectroscopic sensing mechanisms, the key challenge is to determine the spatial-shift information accurately (i.e., the spatial displacement introduced by wavelength shift or biological or chemical surface binding), which is similar to the challenge presented by super-resolution imaging. Here, we report a unique “rainbow” trapping metasurface for on-chip spectrometers and sensors. Combined with super-resolution image processing, the low-setting 4× optical microscope system resolves a displacement of the resonant position within 35 nm on the plasmonic rainbow trapping metasurface with a tiny area as small as 0.002 mm2. This unique feature of the spatial manipulation of efficiently coupled rainbow plasmonic resonances reveals a new platform for miniaturized on-chip spectroscopic analysis with a spectral resolution of 0.032 nm in wavelength shift. Using this low-setting 4× microscope imaging system, we demonstrate a biosensing resolution of 1.92 × 109 exosomes per milliliter for A549-derived exosomes and distinguish between patient samples and healthy controls using exosomal epidermal growth factor receptor (EGFR) expression values, thereby demonstrating a new on-chip sensing system for personalized accurate bio/chemical sensing applications.

The market demands to continuously reduce the feature size and increase the integrated circuits density towards the new century. For the economical and technical considerations, the major wafer sizes are shifting to 150mm and 200mm, and the mass production of 300mm diameter wafers is expected to begin in 2001 or 2002. Consequently, on one hand, the growth and manufacturing of large diameter crystals and wafers bring about a number of technological problems and on the other hand, impurities behavior, defects and surface mor-point defects and the extended defects, and their relations with crystal growth technology. New finding of metallic impurities such as copper and iron has been particularly described. The behavior of oxygen, carbon, hydrogen and nitrogen that impact material performance in multiple ways havs been also discussed. Interaction between points defects and oxygen precipitates has been treated to be of prime importance. Microroughness, hydrophilic surface state and surface chemical bonds have been investigated in current paper by novel and improved characterization techniques. Since silicon based materials as the alternative material systems have received strong growing interest, the manufacturing technologies and applications of SiGe, silicon-on-insulator (SOI) have been introduced and emphasized. Finally, the author outlooks the future scientific and engineering challenges and opportunities for silicon and silicon based materials envisioned for the sub quarter-micro and nanometer integrated circuits as we approach 21st century.

The high-accuracy measurement of complex airfoil surfaces is a critical issue in the inspection of blades. Aiming at this problem, a compound measuring principle is proposed in this paper. Using the principle, the airfoil surface and root datum of a blade are measured based on contact inductance method and non-contact laser triangular method, respectively. And a four-coordinate measuring system is designed and established. Then, on the basis of the mechanical structure of the measuring system, the geometric error of which is analyzed syste-matically. And a corresponding extraction and compensation method is proposed based on the laser interferometry. The experimental results show that the proposed error analysis and compensation methods can improve the accuracy of the four-coordinate measuring system effectively.

Study on Strengthening Technique with Prestressed PBO Fiber Sheets

The application of externally bonded fiber reinforced polymer (FRP) laminates to the exposed faces of concrete members provides an innovative and efficient rehabilitation method for strengthening and upgrading structurally inadequate or functionally obsolete concrete structures. However, FRP laminates unlike the cold worked steel exhibit elastic-rupture behavior and also the limited bond capacity of FRP-concrete interface often fails the retrofitted system in an undesirable brittle manner, which leaves FRP material unused with more reserves. Moreover, enhancements in cracking and yield load due to FRP bonding are not significant. To take full advantage of FRP laminates, more gains can be achieved by prestressing the fibers prior to bonding them. Traditional practice is to pretension fiber sheets impregnated with adhesive or FRP plate, which is time-consuming, difficult to apply in the field and ensure a perfect bond at the interface. A newly-developed PBO fiber possesses high modulus, high strength and higher energy absorption capability as compared to carbon and aramid fibers, and PBO fiber sheet can be pretensioned to over 70% of its tensile strength without being impregnated with adhesive. All these make such material suitable to be prestressed for strengthening concrete structures. Based on the experiments and theoretical studies, a comprehensive strengthening method with prestressed PBO sheet is established including concept, working principle and corresponding countermeasures, whose strengthening effect is validated by both laboratory and field experiments.
