Filing Date: 2000-06-06
Classification: G01R

Abstract:
A machine reable medium storing machine executable software procedure for estimating a lifetime of a floating SOI-MOSFET, causing a processor of the machine to perform the steps of:estimating a hole current Ih.sup.f of said floating SOI-MOSFET under a hot carrier stress condition based on an approximation equation:Ih.sup.f (Id.sup.f /Id.sup.t)Isubwhere Id.sup.f denotes a measured drain current in said floating SOI-MOSFET, and then Id.sup.t and Isub denote a measured drain current and a measured substrate current in a body-fixed SOI-MOSFET respectively; andestimating a lifetime of said floating SOI-MOSFET by using said estimated hole current Ih.sup.f.
