Abstract

A new, physically-based model has been developed to successfully explain the roles of device structure and plasma nonuniformity on charge damage. The model includes an equivalent circuit for the charging of MOS antenna structures exposed to a nonuniform plasma, and the use of SPICE, a circuit simulator, to correlate plasma measurement to breakdown measurements. The model is applied to analyze thin oxide damage in an O2 magnetron plasma asher. The simulation results show good agreement with experimental damage data of “antenna” capacitors using ramp voltage breakdown measurements.
