2. Description of the Related Art This type of matching device for a high frequency power supply for a process device is used for efficiently transmitting electric power by matching the output impedance of the high frequency power supply with the impedance of the load of the process device. As shown in FIG. 2 of the accompanying drawings, the structure is such that a matching circuit composed of a tuning capacitor C1, an inductance coil L, and a variable capacitor C2 is housed in a casing indicated by phantom lines, and this casing has a high frequency input terminal I. And a high-frequency output terminal O are provided, and the matching condition is matched by adjusting the capacitance of the capacitor or the inductance of the inductance coil. The inductance coil used in such a conventional matching device has a helical structure as shown in FIG. 3, and a short-circuiting copper plate S is used to short-circuit necessary windings to change the impedance.
Therefore, the adjustment of the inductance is performed in a winding unit.
In the case of vacuum process equipment, a fixed inductor is usually used for the matching circuit. There is a rolling inductor as a commercially available product, but the contactor is worn out and a large electric power load causes a large current, and the usable range is limited. Under normal operating conditions, the matching condition is adjusted with a variable capacitor, but the matching point is greatly deviated when the device is started up or the condition is changed. Have been changed and adjustments have been made.

By the way, in order to obtain the matching, it is necessary to make the inductor of the coil as fine as possible and easily. However, with a coil having a helical structure that is normally used, it is possible to adjust only one winding unit, and it is impossible to finely adjust the inductance. In addition, the coil with a helical structure is not only bulky in three dimensions, but in order to suppress heat generation by the coil, air cooling is usually used when the current is small, and air cooling is strengthened as the current increases, or the coil is water-cooled from the inside. Has been adopted.
Therefore, the size of the so-called matching box itself becomes large, which is a problem from the viewpoint of space saving.

In order to achieve the above object, a matching device for a high frequency power supply for a process device according to the present invention accommodates a matching circuit composed of a capacitor and a coil in a container and flattens the coil. It is configured in a spiral shape, and each winding of the coil is provided with a plurality of short-circuit taps, and the short-circuit plate is locked to the short-circuit taps in the adjacent windings so that the respective turns of the coil can be selectively short-circuited.

In the matching device of the high frequency power supply for process equipment according to the present invention, since the inductance coil is formed in a flat spiral shape, the length of each winding becomes shorter toward the center of the coil, and therefore the short-circuited position. Changes toward the center of the coil, the amount of change in inductance decreases. As a result, if the short circuit is made between the outer turns, the inductance can be greatly changed, while the short circuit is made between the inner turns. And, the inductance can be finely adjusted. Further, since the coil is flat, the contact surface between the short-circuit plate and the coil is in surface contact, and the high frequency loss can be extremely reduced. Further, by setting the mounting pitch of the short-circuit plate to be constant, the short-circuit plate having the same shape can be used at any position.
