    The problems encountered when using the existing SPICE diode model to represent the I-V characteristics of a Zener diode in the reverse region are examined. A Zener diode macro model that has accurate I-V simulation characteristics and can be easily constructed using SPICE-provided primitives is presented. The static I-V characteristics and temperature response of the diode are reviewed. The perfo... View full abstract»

    Laser post-ionization (PI), a technique that overcomes the greatest handicap of secondary-ion mass spectroscopy (SIMS), namely, its susceptibility to matrix effects is discussed. The SIMS matrix effect is the often unknown relationship between the chemical composition of a solid and the secondary ion yield of an analyte in the sample, which is unpredictable and can vary as much as seven orders of ...

    Progress in automating very-small-scale mechanical processes is reviewed. The special requirements of microautomation are identified, and three applications are examined. They are positioning, electrical probing, and mechanical probing. The architecture and design of a microautomation system are described. Microsensors and microactuators are discussed. The use of magnetics technology for driving t... View full abstract»
