    • 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.
    • 提供包括在天线的平面图中基本上是直的天线的等离子体处理。 天线包括沿着基板的表面设置在同一平面上的两个矩形导体板,使得两个矩形导体板之间具有间隔彼此平行。 两个矩形导体板中的每一个的纵向方向上的一端通过导体连接,以便形成回流导体,其中高频电流在两个矩形导体板中以相反的方向流动。 在与间隔相邻的两个矩形导体板的侧面形成有凹口,并且彼此面对的凹口限定开口。 凹口形成开口。 开口沿天线的纵向分开设置。

    • An inductively-coupled-plasma (ICP) type plasma processing apparatus is provided. The plasma processing includes an antenna which is substantially straight in a plan view of the antenna. A plasma is generated for performing a plasma treatment to a substrate when a high frequency current is applied to the antenna to form an electric field in a vacuum container. The antenna includes two go-and-return conductors closely disposed to each other in an up-down direction, wherein the up-down direction is perpendicular to a surface of the substrate, and the high frequency current is applied to flow in opposite directions between the two go-and-return conductors. An interval is defined by a distance between the two go-and-return conductors in the up-down direction, varies in a longitudinal direction of the antenna.
    • 提供了一种电感耦合等离子体(ICP)型等离子体处理装置。 等离子体处理包括在天线的平面图中基本上是直的天线。 当对天线施加高频电流以在真空容器中形成电场时,产生等离子体,以对衬底进行等离子体处理。 该天线包括在上下方向上彼此紧密配置的两个去耦导体,其中上下方向垂直于衬底的表面,并且施加高频电流以在相对方向之间流动 两个回归导体。 间隔由上下方向上的两个去导体之间的距离限定,在天线的纵向方向上变化。
