T. Iwasaki et al., INFLUENCE OF COOLING CONDITION DURING CRYSTAL-GROWTH OF CZ-SI ON OXIDE BREAKDOWN PROPERTY (REPRINTED FROM OYO-BUTSURI, VOL 65, 1996), Journal of the Electrochemical Society, 143(10), 1996, pp. 3383-3388
In order to study the influence of the cooling condition of growing CZ
-Si crystals on gate oxide integrity (GOI) and the formation mechanism
of the defects that deteriorate GOI, we have conducted growth-halting
experiments and heat-treatment experiments to simulate the cooling pa
tterns of the growing crystals. We have found that GOI and the defect
formation are strongly affected by the cooling condition in a critical
temperature range around 1050 degrees C.
