Kl. Yeh et al., Fluorinated thin gate oxides prepared by room temperature deposition followed by furnace oxidation, SOL ST ELEC, 43(3), 1999, pp. 671-676
Room temperature deposition in H2SiF6 solution, i.e., liquid phase depositi
on (LPD), followed by furnace oxidation (FO) is first used to prepare fluor
inated thin oxides (LPD/FO). The amount of fluorine existing in the gate ox
ide is controlled by varying the LPD time in this work. A turnaround breakd
own behavior is observed for LPD/FO oxides with various LPD conditions. The
oxide with an optimized fluorine concentration shows a significant improve
ment in oxide breakdown characteristics. (C) 1999 Elsevier Science Ltd. All
