Abstract

PROBLEM TO BE SOLVED: To obtain a sputtering device capable of forming a film good in the film thickness and characteristic distribution on a stationary or moving large- sized substrate. SOLUTION: A film is formed by sputtering on a stationary or moving substrate 1 opposed to a target 7 provided to a cathode 6 in a vacuum film forming chamber 2 with use of this device. A gridlike anode 12 is set between the target and substrate, and the opening degree of the anode is controlled to 80-97%. As a result, plasma is fixed, a film good in the film thickness and characteristic distribution is formed on a stationary or moving large-sized substrate with good reproducibility by the large-sized open-type target 7. Since the electron in the plasma is trapped by the anode 12, an abnormal discharge on the substrate 1 is prevented, and an undamaged film is formed.

To further explain this, in the above-mentioned single-wafer apparatus for forming a film on a stationary substrate, a target which is slightly larger than the substrate and is installed facing the substrate is used. The target is a permanent magnet on the back surface. Alternatively, it is attached to a magnetron cathode equipped with a magnetic circuit composed of electromagnets, and a magnetron discharge is generated in front of the target by energizing the cathode to form a film of the target material on the substrate. Usually, a permanent magnet or an electromagnet is swung to swing a magnetic field in front of the target so that the entire surface of the target is eroded and the film characteristics are made uniform. On the other hand, in the in-line type device, a magnetron cathode of a type in which a fixed magnetic circuit with a permanent magnet attached to the back surface of the cathode is provided to generate magnetron discharge is generally used, but the low efficiency of use of the target and the life of the target However, the magnetron cathode of the type that oscillates the magnetic circuit of the permanent magnet is used as the target because it has a problem that it cannot supply high power due to the heating of the erosion area due to discharge. ing. With this cathode, the use efficiency of the target is improved due to the swing of the magnetic circuit, the erosion area moves, the cooling efficiency improves, and it is possible to input high power. The effect is that the life of the target is significantly extended.

Example 1 As a target 7 of the apparatus shown in FIG.

Was applied, and the film thickness was adjusted to about 1000 angstroms by adjusting the energizing time. The substrate 1 used is 300 mm ×
A 400 mm glass substrate was used, and the film thickness distribution in the X-axis direction (400 mm direction of the substrate) indicated by the arrow in FIG. 1 was measured. The result was almost uniform as shown by the curve A in FIG. 4, and the film thickness at both ends of the substrate 1 increased like the curve B when the grid anode was not used. This is because, in the state where the lattice anode 12 is not present, the plasma is concentrated on the portion closer to the deposition shield plate 11 than the center portion of the target 7 because the surrounding deposition shield plate 11 functions as an anode. On the other hand, in the case of the present invention using the lattice anode 12, the target 7
Since the plasma was uniformly fixed above, a uniform film thickness distribution was obtained within the substrate 1.

Example 2 As a target 7 of the apparatus shown in FIG.
n 2 O 3 - with 10at% SnO 2 of ITO sintered body, a mixed gas of Ar-5at% O 2 as the sputtering gas was the gas pressure and 0.67 Pa. An ITO film was formed on the glass substrate 1 by changing the aperture ratio of the grid-like anode 12 with the direct current applied to the cathode 6 to be 1 Kw and 4 Kw. The substrate transfer speed was adjusted so that the film thickness was 1000 angstroms. The results are shown in Table 1 and 1Kw
If no grid anode is used (aperture ratio 100%),
An abnormal discharge occurred on the substrate, but when the aperture ratio of the lattice anode 12 was 97% or less, electrons in the plasma were trapped by the anode and no abnormal discharge on the substrate due to charge-up was observed. On the other hand, when 4 Kw was input, abnormal discharge was observed up to an aperture ratio of 85%, and the occurrence of abnormal discharge could be suppressed by reducing the aperture ratio to 80%. Therefore, the aperture ratio is 80 ~ depending on the input power.
It is desirable to set it in the range of 97%.

As described above, according to the present invention, since the grid-shaped anode is installed between the target of the sputtering apparatus and the substrate, the plasma can be fixed and the large substrate can be stationary or moving. With a large open target, a film with a good distribution of film thickness and film characteristics can be formed with good reproducibility. Since the anode traps electrons in plasma, abnormal discharge on the substrate can be prevented and no damage occurs. There is an effect that film formation can be performed, and this effect can increase the aperture ratio of the anode to 80
When the cathode is a magnetron cathode, it is not necessary to oscillate the magnetic circuit behind the cathode, and the structure of the cathode can be simplified.
