An object of the present invention is to provide a thin film transistor having a gate insulating film for suppressing a shift amount of a threshold voltage generated by use under a high temperature environment. In a thin film transistor having a channel layer made of microcrystalline silicon, a gate insulating film 140 is a film obtained by laminating a first silicon nitride film 141 having a nitrogen concentration of 6×1021 atoms / cc or less and a second silicon nitride film 142 having a nitrogen concentration higher than 6×1021 atoms / cc. Therefore, the second silicon nitride film 142 increases the blocking effect against mobile ions entering from a glass substrate 20 to make the mobile ions less likely to be stored in an interface with a channel layer 50. The first silicon nitride film 141 increases the dielectric breakdown voltage of the gate insulating film 140.

Semiconductor device

A first metal film and a second metal film, both of which are made of Ni or the like, are deposited on the upper surface of a substrate made of SiC. In such a state, the interface between the first metal film and the substrate and the interface between the second metal film and the substrate both form a Schottky contact. Next, laser light is irradiated from above the upper surface of the substrate only onto the first metal film on the substrate after the diameter of the top end of the laser light has been reduced. Thus, since the metal-semiconductor interface between the first metal film and the substrate is turned into an alloy owing to the energy of the laser light without heating the entire substrate, an ohmic contact can be formed in the interface between the first metal film and the substrate. As a result, an ohmic electrode can be constituted by the first metal film.
