摘要
To solve the mobility balance issue in nanosheet FETs (NSFETs) and complementary FETs (CFETs), the aggressive approach using hetero-oriented integration with Ge channels was demonstrated by low temperature hetero-layer bonding technology (LT-HBT). Good manufacturability of the hetero-oriented Ge platform was verified with XRD 2?-? scan, Raman spectra, Selected Area Diffraction (SAD), and Converged Beam Electron Diffraction (CBED). Balanced device performance in terms of C-V, ID-VG, ID-VD and ?c for Ge (111) nFET and Ge (100) pFET was achieved, leading to better VTCs and voltage gains. © 2022 IEEE.
