Abstract
A semiconductor device includes a film containing silicon as the main ingredient, and an aluminum alloy film, such as a source electrode and a drain electrode, that is directly connected to the film containing silicon as the main ingredient, such as an ohmic low-resistance Si film, and contains at least Al, Ni, and N in the vicinity of the bonding interface. The Aluminum alloy film has a good contact characteristic when directly connected to the film containing silicon as the main ingredient without having a barrier layer formed of high melting point metal.
