Oxide semiconductor field-effect transistors (OSFETs) can be stacked over silicon (Si) field-effect transistors (FETs). We used this technology to form Si–oxide semiconductor composite LSI and prototyped an OLED display in which Si FETs and OSFETs are monolithically stacked. This stacking enabled a larger screen and a lower power driver.
