▎ 摘　　要

NOVELTY - Semiconductor device comprises a metal layer, a semiconductor layer in electrical contact with the metal layer, a two-dimensional (2D) material layer between the metal layer and the semiconductor layer and having a 2D crystal structure, and a metal compound layer between the 2D material layer and the semiconductor layer. USE - Semiconductor device. ADVANTAGE - The semiconductor device inhibits or reduces the likelihood of a portion of a reaction source from reacting with a material of the semiconductor layer in the manufacturing process, and prevents or reduces or mitigates an increase in contact resistivity due to a semiconductor oxide film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the structure of a semiconductor device.
