Pinpointing the Dominant Component of Contact Resistance to Atomically Thin Semiconductors


Abstract "Achieving good electrical contacts is one of the major challenges in realizing devices based on atomically thin two-dimensional (2D) semiconductors. Several studies have examined this hurdle, but a universal understanding of the contact resistance and an underlying approach to its reduction are currently lacking. In this work we expose the shortcomings of the classical contact resist... » read more

Digging Much Deeper With Unit Retest


Keeping test costs flat in the face of product complexity continues to challenge both product and test engineers. Increased data collection at package-level test and the ability to respond to it in a never-before level of detail has prompted device makers and assembly and test houses to tighten up their retest processes. Test metrology, socket contamination, and mechanical alignment have alw... » read more

Managing Wafer Retest


Every wafer test touch-down requires a balance between a good electrical contact and preventing damage to the wafer and probe card. Done wrong, it can ruin a wafer and the customized probe card and result in poor yield, as well as failures in the field. Achieving this balance requires good wafer probing process procedures as well as monitoring of the resulting process parameters, much of it ... » read more
