I-V Tracer simulates this functionality by providing direct control over the output level, letting failure analysis engineers slowly ramp up to an I-V curve anomaly then seamlessly creep into the behavior, with a minimum of 500 nV (or 500 fA) resolution on the sourced output.

PLASMA CLEANER FOR TEM SAMPLE HOLDER MAINTENANCE The SPI Supplies Plasma Prep III Plasma Cleaner is a compact benchtop plasma cleaner that uses a dry plasma process for the removal of contamination on the TEM specimen holder. The unit can also be used to clean the sample itself or to expose the sample to a glow discharge process. The unit features a barrel-type design for isotropic plasma cleaning, which is the ideal geometry to get into the various nooks and crannies of the specimen holder and contact areas between the specimen itself and the holder assembly. The Plasma Prep III has a compact, efficient design and small footprint, with room inside to process samples in batch quantities. It is also highly portable, weighing only 32 lbs not including a separately installed vacuum pump. For more information, visit 2spi.com. THERMALLY CONDUCTIVE EPOXY COMBINES STRONG BONDING WITH ROBUST THERMAL PERFORMANCE Loctite Ablestik TE 3530 is a highly thermally conductive epoxy adhesive for bonding heat sensitive components. This one-part, low viscosity, thermally conductive epoxy adhesive is specially formulated to bond heat dissipating components and can be applied using automatic syringe dispensing. This high dielectric, low-viscosity adhesive cures at low temperatures, making it perfect for use in sensor attach and die attach applications. It can be applied using an automatic syringe dispensing method. Ablestik TE 3530 has high thermal conductivity (2.3 W/m-K), high dielectric value, and high electrical re- sistivity. TE 3530 should be stored at temperatures be- tween -25 and -18°C. For more information, visit henkel-adhesives.com. Epoxy provides robust thermal performance. The SPI Supplies Plasma Prep III is a compact benchtop plasma cleaner. The unit uses the same plasma cleaner design as was used by Dr. Nestor Zaluzec leading to the discovery that if this kind of contamination is removed, the contamination rates on samples are greatly reduced. Therefore, one sees a significant increase in the contrast and overall quality of the final TEM image. SPI Supplies manufactures and offers such plasma cleaning equipment according to the terms of a license agreement granted by Argonne National Laboratory. The Plasma Prep III is capable of 1 to 100 W operation with most applications using the 1 to 10 W range. This low wattage allows operation with argon without having a deleterious impact on either the specimen holder, rod, or the specimen itself. This low power is enough to dis- lodge surface-held contamination but not enough to etch the sample, rod, or holder assembly.
