Temperature Dependence of Ni-InGaAs Reaction Previous Study: • Fix RTA annealing temperature at 250 ‘C • Fin width Dependent (50nm, 80nm, 100nm, 120nm, 150nm, 250nm, 550nm) • Time Dependent (5min, 20min, 40min, 60min, 90min) Plan:
in-situ HRTEM Study of Ni-InGaAs Ni Ni Directly fabricate Fins on top InP InGaAs InP Deposit Ni PMMA Spin-coating & InP etching Ni Ni Ni Ni Transfer to TEM grid InP Cu TEM grid with lace carbon
Copper Mesa Grid Different size/pitch available: http://www.tedpella.com/grids_html/gilder.htm#anchor1540234 1. To avoid Cu influence on the Ni-InGaAs reaction study, Cu grid can be pre-coated with HfO2 in ALD. 2. For better transfer, Cu grid can be embedded into PMMA during spin-coating.
