C. Russ et al., Non-uniform triggering of gg-nMOSt investigated by combined emission microscopy and transmission line pulsing, MICROEL REL, 39(11), 1999, pp. 1551-1561
The triggering of grounded-gate nMOS transistors and field-oxide devices, e
ssential for optimized protection design, is addressed by transmission line
pulser (TLP)-pulsed emission microscopy. Current non-uniformity and instab
ility effects in snapback operation under DC and TLP conditions are demonst
rated. The comprehensive correlation of emission and electrical behavior al
lows an improved interpretation of device operation. Technological influenc
es on the trigger uniformity are discussed. (C) 1999 Elsevier Science Ltd.
