    Abstract: MOSFET (30) comprises an SiC film (11). The SiC film (11) has a facet on its surface. The length of one period of the facet is not less than 100 nm, and the facet functions as a channel (16). The process for producing MOSFET (30) comprises the steps of forming an SiC film (11), heat treating the SiC film (11) in such a state that Si is fed onto the surface of the SiC film (11), and bringing the facet provided on the surface of the SiC film (11) by the heat treatment step to a channel (16). According to the above constitution, the properties can be satisfactorily improved.

    Abstract: A method for manufacturing a surface emitting laser element (1) comprises a step of preparing conductive GaN composite region substrate including a high-dislocation density high-conductivity region (10a), a low-dislocation density high-conductivity region (10b), and low-dislocation density low-conductivity region (10c) as a conductive GaN substrate (10), a semiconductor layer multilayer-body fabricating step of fabricating III-V group compound semiconductor layer multilayer bodies (20) including a light-emitting layer (200) on the substrate, and an electrode forming step of forming a semiconductor-side electrode (15) and a substrate-side electrode (11). The method is characterized in that the semiconductor layer and the electrodes are so formed that the light-emitting region (200a) which is formed in the light-emitting layer (200) and into which carriers flows is in the upper portion of the low-dislocation density high-conductivity region (10b). Thus, a surface emitting laser element where light emission from the light-emitting region is uniform can be produced with high production yield.
