As several industry pundits have expressed in recent years: "the era of 'one test method fits all' seems well behind us." For most test managers with even a modest mix of products, trying to formulate a test policy/philosophy has become a tricky balancing act at the best of times. James Stanbridge, Sales Manager UK for JTAG Technologies, and Steve Lees Managing Director of ATE Solutions look at the options.

Boundary-scan (1149.1) technology was originally developed to provide a far easier method to perform digital DC testing to detect intra-IC interconnect assembly faults, such as solder shorts and opens. Today's advanced IC technology now includes high-speed differential interfaces that include AC or DC coupling components loaded on the printed circuit assembly. Simple stuck-at-high/low test methods are not sufficient to detect all assembly fault conditions, which includes shorts, opens and missing components. Improved diagnostics requires detailed circuit analysis, predictive assembly fault simulation and more complex testing to isolate and accurately detect all possible assembly faults...

In 1998, the International 300 mm Initiative (I300I) demonstration and characterization programs will focus on 180 nm technology capability. To support these activities, I300I and equipment supplier demonstration partners must use starting silicon wafers with key parameters specified at a level appropriate level for 180 nm processing, including contamination and lithographic patterning. This document describes I300I's silicon wafer specifications, as developed with the I300I Silicon Working Group (member company technical advisors) and SEMI Standards.

Surface plasmon polaritons (SPPs) are localized surface electromagnetic waves that propagate along the interface between a metal and a dielectric. Owing to their inherent subwavelength confinement, SPPs have a strong potential to become building blocks of a type of photonic circuitry built up on 2D metal surfaces; however, SPPs are difficult to control on curved surfaces conformably and flexibly to produce advanced functional devices. Here we propose the concept of conformal surface plasmons (CSPs), surface plasmon waves that can propagate on ultrathin and flexible films to long distances in a wide broadband range from microwave to mid-infrared frequencies.
