1.3.ESDprecautions

Certainsemiconductordevicescanbeeasilydamagedbystaticelectricity.Suchcomponentsarecommonlycalled

“ElectrostaticallySensitive(ES)Devices”orESDs.ExamplesoftypicalESDsare:integratedcircuits,someeldeffect

transistors,andsemiconductor“chip”components.Thetechniquesoutlinedbelowshouldbefollowedtohelpreducethe
