Popis: We have fabricated large area integrated top-gate ${n}$ MISFETs with sputter-deposited-MoS2 film having n-type operation. A sputtering method enables us to form a large-area MoS2 thin film followed by H2S annealing to compensate sulfur vacancies. Two passivation films of ALD-Al2O3 enhance the process endurance of MoS2 channel. Therefore, we demonstrate TiN-top-gate ${n}$ MISFET, which is a substantial first step to realize industrial chip-level LSIs with MoS2-channel FETs.
