Abstract :
The substrate resistivity has a serious impact on the behaviour of ESD protection devices. TLP characterisation and failure analysis show that different failure mechanisms occur, depending on the substrate resistivity. The mechanisms leading to these phenomena are explained and the consequences for porting IO designs to other substrate types are discussed.
