Abstract :
An antenna test element group (TEG), used for the evaluation of wafer charging in semiconductor fabrication, is applied to ion milling in the fabrication of GMR heads. The antenna TEG can quantitatively evaluate the potential for ESD damage to the GMR heads. The differences between thermal electron and microwave plasma neutralization are discussed.
