The antenna has a structure that the high frequency electrode is received in a dielectric case. The high frequency electrode has a go-and-return conductor structure that two electrode conductors are disposed close to and in parallel to each other with a gap therebetween to form a rectangular plate shape as a whole, and the two electrode conductors are connected by a conductor at an end in the longitudinal direction. A high frequency current flows in the two electrode conductors in opposite directions. A plurality of openings are formed on edges of the two electrode conductors on the side of the gap, and the openings are dispersed and arranged in the longitudinal direction of the high frequency electrode. The antenna is disposed in a vacuum container in a direction that a main surface of the high frequency electrode and a surface of the substrate are substantially perpendicular to each other.


A plasma device including a vacuum container, an arc-type evaporation source, a negative electrode member, a shutter, a power source, and a trigger electrode is described. The arc-type evaporation source is fixed to the side wall of the vacuum container so as to face the substrate. The negative electrode member is made from vitreous carbon having a protrusion and is mounted on the arc-type evaporation source. The power source applies a negative voltage to the arc-type evaporation source. The trigger electrode comes into contact with or separates away from the protrusion on the negative electrode member. A negative voltage is applied to the arc-type evaporation source, the trigger electrode is brought into contact with the protrusion on the negative electrode member, an arc discharge is generated, the shutter is opened, and a carbon thin film is formed on the substrate.

A method for fabricating a thin-film transistor is described. A structure is provided, including a substrate transmitting an excimer laser light, a diffusion prevention film on the substrate, a gate electrode and a gate insulating film on the diffusion prevention film, and an oxide semiconductor layer on the gate insulating film.

The plasma processing including an antenna which is substantially straight in a plan view of the antenna is provided. The antenna includes two rectangular conductor plates disposed on a same plane along a surface of a substrate in a manner that the two rectangular conductor plates are parallel to each other with an interval therebetween. An end of a side in a longitudinal direction of each of the two rectangular conductor plates is connected through a conductor so as to form a go-and-return conductor, wherein the high frequency current flows in the two rectangular conductor plates in opposite directions. Notches are formed at the sides of the two rectangular conductor plates adjacent to the interval and the notches facing each other define an opening. The notches form the openings. The openings are separately arranged in the longitudinal direction of the antenna.
