Abstract
A semiconductor device includes a substrate, a device layer, and a film. The substrate includes a first semiconductor element, and has a first surface, a second surface, and a side surface between the first surface and the second surface. The device layer includes a second semiconductor element electrically connected to the first semiconductor element, and is provided on the first surface of the substrate. The film includes a first film including a first region, a second region, and a third region. The substrate is positioned between the first region and the device layer in a first direction. The substrate is positioned between the second region and the third region in a second direction crossing the first direction. The first film fills the unevenness of the second surface and the side surface.
