Abstract

A semiconductor device includes an insulating substrate, a first semiconductor layer formed of silicon and positioned above the insulating substrate, a second semiconductor layer formed of a metal oxide and positioned above the first semiconductor layer, a first insulating film formed of a silicon nitride and positioned between the first semiconductor layer and the second semiconductor layer, and a block layer positioned between the first semiconductor film and the second semiconductor layer, the block layer hydrogen diffusion of which is lower than that of the first insulating film.
