Electrostatic discharge failure characteristics of oxide vertical cavity surface emitting lasers
Fig. 1. Typical test circuit models of an ESD. (a) HBM; (b) MM; (c) CDM and (d) corresponding current waveforms
Fig. 2. (a) Comparison of L-I-V curve before and after forward HBM shock. Inset is an EMMI image under 700 V impulse voltage. (b) PV-TEM, the insert is an enlarged view of the white dotted part and (c) XS-TEM after forward HBM shock under 700 V impulse voltage, the insert is XS-TEM near the oxide tip of sample without an ESD shock
Fig. 3. (a) Comparison of L-I-V curve before and after reverse HBM shock. The insert is an EMMI image under 180 V impulse voltage. (b) PV-TEM and (c) XS-TEM after reverse HBM shock under 180 V impulse voltage
Fig. 4. (a) Comparison of L-I-V curve before and after forward/reverse HBM shock. The insert is an EMMI image under 160 V impulse voltage. (b) PV-TEM and (c) XS-TEM after forward/reverse HBM shock under an 160 V impulse voltage
Fig. 5. (a) Comparison of L-I-V curve before and after MM shock. The insert is an EMMI image under a damaging impulse voltage. (b) PV-TEM and (c) XS-TEM after MM shock
Fig. 6. (a) Comparison of L-I-V curve before and after CDM shock. The insert is an EMMI image under a 2000 V impulse voltage; (b) PV-TEM and (c) XS-TEM after CDM shock
Fig. 7. (a) Comparison of L-I-V curve before and after EOS shock. The inset is an EMMI image under a 45 mA 960 s surge; (b) PV-TEM and (c) XS-TEM after EOS shock under a 45 mA 960 s surge. The inserts are partial enlarged views.
