Glass provides many opportunities for advanced packaging. The material properties give many opportunities. As an insulator, glass provides advantages in providing low electrical loss, particularly at high frequencies. The relatively high stiffness and ability to adjust coefficient of thermal expansion gives advantages to manage warp in glass core substrates and bonded stacks. Forming processes allow the potential to both form in panel format as well as to form at thicknesses as low as 100 um, giving opportunities to provide cost-effective solutions for the industry. Via fabrication technology development continues to advance providing via diameters < 20 um in size in production ready environment. [1–5] As the industry adopts glass solutions, significant advancements have been made in downstream processes such as glass handling and via/surface metallization. We will provide an update on advancements in these areas as well as handling techniques to achieve desired process flows. There also continues to be increasing amounts of data showing the ability to achieve electrical and thermo-mechanical reliability of substrates with TGV and latest data here will also be provided.

Ceramic Reactors

Ceramic reactors, which convert materials and energy electrochemically, are expected to solve various environmental problems, and the use of a microreactor design was shown to realize a high performance reactor with high thermal durability, operable at lower temperatures. Our research project, “Advanced Ceramic Reactor,” supported by the New Energy and Industrial Technology Development Organization, targets to develop new fabrication technology for such microreactors and modules using conventional, commercially available materials. In this study, fabrication technology of microtubular ceramic reactors have been investigated for aiming solid oxide fuel cell (SOFC) applications such as small distributed power generators, auxiliary power units for vehicles, and portable power sources. So far, microtubular SOFCs under a diameter of 1 mm using doped ceria electrolyte, and Ni–ceria based cermet for tubular support has been successfully developed and evaluated. The single microtubular SOFC showed a cell performance of 0.46 W/cm2 (at 0.7 V) at 550°C with H2 fuel. The bundle design for such tubular cell was also proposed and fabricated. The discussion will cover the fabrication technology of a single tubular SOFC and bundle, and the optimization of the cell and bundle design by considering gas pressure loss and current collecting loss.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

Circuits Vlsi

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.
