A new P-type amorphous SnO thin-film transistor with high I_on/I_off ratio of >10⁴ is developed, for the first time, as a component to complement N-type IGZO transistors for on-chip voltage-bridging BEOL-CMOS I/Os on conventional Si-LSI Cu-interconnects (Fig. 1). Dedicated low-temperature (<;400°C) oxide-semiconductor processes are implemented to overcome several integration challenges (Fig. 2) with only one-mask addition using standard BEOL process tools (Fig. 3… Expand
