Physical limitation of the cascoded snapback NMOS ESD protection capability due to the non-uniform turn-off

The nonlinear effects and physical failure mechanism in over-voltage protection NMOS snapback structures during ESD operation have been analyzed with the use of experimental test structures as well as process and device simulations. A phenomenological explanation has been provided to account for the effect due to substrate type and the use of a so-called ESD implant. A generic design solution for the cascoded snapback NMOS structure suitable for 5-V tolerant I/O applications is proposed, one that delivers robust operation and eliminates the requirement for an additional ESD implant.     

Selecting the Batch Composition in Briquetting

A new approach to selecting the optimal batch composition and properties in briquetting is proposed. To that end, the influence of the batch composition and properties on briquet production and applicability is analyzed. On that basis, four basic aspects of the stepwise optimization of batch composition and properties are considered. For each aspect, the conditions on the batch are formulated. Optimization criteria are developed and used to select the best batch composition.
