- a reactive gas such as oxygen or nitrogen is introduced together with an inert gas such as argon in order to perform sputtering in a vacuum chamber.
- an inert gas such as argon
- argon ions in the generated plasma collide with the target material, and target material particles are knocked out.
- the target material particles react with the reactive gas and are generated by the reaction.
- a film of a reactive substance is deposited on the substrate. If the concentration of the reactive gas is high, the surface of the target material reacts with the reactive gas to form a compound layer, which is sputtered to deposit a reactive material having a desired composition on the substrate.

Therefore, even if the reactive gas is supplied one after another, the reactive gas is first consumed by the reaction outside the plasma, so that a concentration gradient of the reactive gas may occur between the outside and the inside of the plasma. As a result, there may be a problem that the quality of the film deposited on the substrate is different between the central portion and the outer peripheral portion of the substrate.

A gas concentration gradient such as a reactive gas can be reduced by the gas supplied from the hole 13 to the film formation chamber. Therefore, as shown in FIG. 3, the arrangement of the plurality of holes 13 along the longitudinal direction of the gas introduction groove 5 can supply the gas uniformly in the region where the plasma is generated, thereby making the concentration gradient more uniform. This is preferable.
- the gas can be supplied into the generated plasma, so that the concentration gradient of the gas can be reduced accordingly.

That is, the backing plates 2a to 2c are positioned so that the gap 15 between each of the backing plates 2a to 2c and at least a part of the hole 13 overlap. Further, since the gas passing through the gap 15 needs to be introduced into the film forming chamber, the gap 14 between each of the targets 1 a to 1 c overlaps at least a part of the gap 15. By forming the gap 14 and the gap 15 in this way, the gas introduced from the gas introduction groove 5 can be supplied to the film forming chamber.

- the gas introduction mechanism 5 is connected to the atmosphere-side gas introduction pipe 11 ⁇ / b> B through a gas introduction groove provided in the partition plate 3. Accordingly, even when a gas introduction path is provided between the target 1 and the magnet 8 so as to supply gas into the generated plasma, the distance between the target 1 and the magnet 8 can be shortened. The magnetic field intensity on one surface can be increased.

- the targets 1a to 1c are arranged on the backing plates 2a to 2c so as to overlap at least part of the gap.
- the mixed gas is introduced through the first gas introduction mechanism introduced directly into the vacuum vessel, the gas introduction groove 5 inside the partition plate 3 and the gap included in the backing plate 2 and the target 1 from the gas outlet 4.

Note that power is supplied from the DC power source to the target 1 through the partition plate 3 through a power supply path that penetrates the insulating plate.
- the vacuum vessel is provided with the first gas introduction mechanism and the second gas introduction mechanism, and the mixed gas containing the inert gas and the reactive gas is supplied from each of them. It is not essential to introduce the mixed gas from both the gas introduction mechanism and the second gas introduction mechanism.
- the essence of the present invention is to make the concentration gradient of the reactive gas uniform in the region where the plasma is generated. In the present invention, if the reactive gas is supplied from the second gas introduction mechanism, the concentration gradient of the reactive gas can be reduced.
- the inert gas for sputtering the target may be introduced from the first gas introduction mechanism. That is, at least the reactive gas may be supplied from the second gas introduction mechanism, and at least the inert gas may be supplied from the first gas introduction mechanism.
- the plurality of backing plates 2a to 2c and the targets 1a to 1c are arranged with gaps, and the gas introduction grooves 5 connected to the gas introduction pipe 11B along the longitudinal direction of the gaps.
- the gaps 14 and 15 are formed so that the gas supplied from the gas introduction groove 5 can pass therethrough. Therefore, since the reactive gas can be supplied from the region in the target to the region between the cathode mechanism and the substrate 6, the concentration gradient of the reactive gas can be reduced in the generated plasma region. Therefore, the film quality formed on the substrate can be made uniform.
- the gap between the backing plates functions as a part of the gas introduction path. Therefore, accumulation of particles in the gap is suppressed, and generation of nodules and particles can be reduced.
- a plurality of backing plates and a plurality of targets are used, and a part of the gas introduction path is formed using a gap when these are arranged. Therefore, the gas can be supplied to the region between the cathode mechanism and the substrate without performing the process of making a hole in the target or the backing plate or the process of providing the insertion member as in Patent Document 1. Therefore, reactive sputtering can be performed with reduced costs. Further, it is not necessary to use the above processing, and the gas introduction path can be formed by arranging the backing plate and the target as described above. Therefore, the existing backing plate and target can be used without being processed, and the substrate and the target can be easily enlarged.
- the second gas introduction mechanism is a mechanism for supplying gas so that the concentration gradient of the reactive gas is reduced in the region between the cathode mechanism and the substrate 6 where the plasma is generated. Therefore, even if the first gas introduction mechanism including the gas introduction pipe 11A is not provided, the inert gas and the reactive gas are supplied to the region where the plasma is generated, and the concentration gradient of the reactive gas is made uniform. be able to.
