Apparatus and methods for determining floating body effects in SOI devices

摘要

Methods and systems are described for determining floating body delay effects in an SOI wafer, wherein test apparatus is provided in a wafer comprising a plurality of floating body devices fabricated in series in the wafer, and a pulse generation circuit providing a pulse output corresponding to a delay time associated with the floating body chain according to an input pulse edge and a propagated pulse edge from the floating body devices.
