To enable transistor scaling into the 21st century, new solutions such as high dielectric constaConventional scaling of gate oxide thickness, source/drain extension (SDE), junction depths, and gate lengths have enabled MOS gate dimensions to be reduced from 10mm in the 1970’s to a present day size of 0.1mm. To enable transistor scaling into the 21st century, new solutions such as high dielectric constant materials for gate insulation and shallow, ultra low resistivity junctions need to be developed. In this paper, for the first time, key scaling limits are quantified for MOS transistorsnt materials for gate insulation and shallow, ultra low resistivity junctions need to be developed.

Powerful desktop multiprocessor systems based on the Intel Architecture (iA) offer a formidable alternative to traditional scientific/engineering workstations for commercial application developers at an attractive costperformance ratio. However, the lack of adequate compiler and runtime library support for multithreading and parallel processing on Windows NT* makes it difficult or impossible to fully exploit the performance advantage of these multiprocessor systems. In this paper we describe the design, development, and initial performance results of the Illinois-Intel Multithreading Library (IML), which aims at providing an efficient and powerful (in terms of types of parallelism it supports) API for multithreaded application developers.

Many Original Equipment Manufacturers, (OEM’s), struggle to continue shipping aging or obsolete electronic products. Electronic products designed five to ten years ago are still relevant in the marketplace. Often these venerable old products have gained particular acceptance amongst a select group of customers. In many cases these old products fulfill a need in a unique manner. Examples include: designs that are grandfathered into an application due to regulatory considerations; designs having unique form-fit-and-function; designs running special software ; designs subject to contractual support and service requirements; designs in which a new contract stipulates delivery of older gear as part of a larger system offering. Any one or all of these reasons can lead an OEM to continue the production of electronic equipment well into its end of useful component life

Bilayer graphene has been a subject of intense study in recent years. The interlayer registry between the layers can have dramatic effects on the electronic properties: for example, in the presence of a perpendicular electric field, a band gap appears in the electronic spectrum of so-called Bernal-stacked graphene. This band gap is intimately tied to a structural spontaneous symmetry breaking in bilayer graphene, where one of the graphene layers shifts by an atomic spacing with respect to the other. This shift can happen in multiple directions, resulting in multiple stacking domains with soliton-like structural boundaries between them

Understanding your process and how to minimize defects has always been important. Nowadays, its importance is increasing with the complexity of products and the customers demand for higher quality. Quality Management Solutions (QMS) that integrate real-time test and inspection results with engineering and production data, can allow the optimization of the entire manufacturing process. We will describe the cost and time benefits of a QMS system when integrated with engineering data and manufacturing processes. We will use real examples that can be derived from integrating this data. This paper also discusses the aspects of Quality Management Software that enables electronic manufacturers to efficiently deliver products while achieving higher quality, reduce manufacturing costs and cutting repair time. Key words: Quality Management Software, ICT, Repair workstations, First Pass Yield, Pareto analysis, Flying Probe, QMS.

Smart phones are complex, costly devices and therefore need to be reworked correctly the first time. In order to meet the ever-growing demand for performance, the complexity of mobile devices has increased immensely, with more than a 70% greater number of packages now found inside of them than just a few years ago. For instance, 1080P HD camera and video capabilities are now available on most high end smart phones or tablet computers, making their production more elaborate and expensive. The printed circuit boards for these devices are no longer considered disposable goods, and their bill of materials start from $150.00, with higher end smart phones going up to $238.00, and tablets well over $300.00.

Printed electronics is a familiar term that is taking on more meaning as the technology matures. Flexible electronics is sometimes referred to as a subset of this and the printing approach is one of the enabling factors for roll to roll processes. Printed electronics is improving in performance and has many applications that compete directly with printed circuit boards. The advantage of roll to roll is the speed of manufacturing, the large areas possible, and a reduction in costs. As this technology continues to mature, it is also merging with the high profile 3D printing. (...)This paper will show working demonstrations of printed circuit structures, the obstacles, and the potential future of 3D printed electronics.

Interconnect reliability especially in BGA solder joints and compliant pins are subjected to design parameters which are very critical to ensure product performance at pre-defined shipping condition and user environment. Plating thickness of compliant pin and damping mechanism of electronic system design are key successful factors for this purpose. In additional transportation and material handling process of a computer server system will be affected by shock under certain conditions. Many accessories devices in the server computer system tend to become loose resulting in poor contact or solder intermittent interconnect problems due to the shock load from the transportation and material handling processes.

The interfacing of soft and hard electronics is a key challenge for flexible hybrid electronics. Currently, a multisubstrate approach is employed, where soft and hard devices are fabricated or assembled on separate substrates, and bonded or interfaced using connectors; this hinders the flexibility of the device and is prone to interconnect issues. Here, a single substrate interfacing approach is reported, where soft devices, i.e., sensors, are directly printed on Kapton polyimide substrates that are widely used for fabricating flexible printed circuit boards (FPCBs).

The solderability of a nickel-palladium-gold (Ni-Pd-Au) finish on a Cu substrate was evaluated for the Pb-free solder, 95.5Sn-3.9Ag-0.6 Cu (wt.%, abbreviated Sn-Ag-Cu) and the eutectic 63Sn-37 Pb (Sn-Pb) alloy. The solder temperature was 245ºC. The flux was a rosin-based mildly activated (RMA) solution. The Ni-Pd-Au finish was tested in the as-fabricated condition as well as after exposure to one of the following accelerated storage (shelf life) regiments: (1) 33.6, 67.2, or 336 hours in the Battelle Class 2 flowing gas environment or (2) 5, 16, or 24 hours of steam aging (88ºC, 90%RH).
