The first metal-ferroelectric-insulator-semiconductor field effect transist
ors (MFIS FETs) using Pt/Pb5Ge3O11/ZrO2/Si structure has been successfully
fabricated. The integration process is simple and reliable, and it is fully
compatible with conventional complementary metal oxide semiconductor (CMOS
) process. The smallest working device obtained is 0.3 mum x 0.5 mum (L x W
). The memory window is as large as 3 V and it is not dependent on device s
ize. The endurance of the device is at least 10(8) cycles without degradati
on. The memory window decreased to 80% and 75% of initial values after 10(4
) seconds retention tests at room temperature and 100 degreesC respectively
