Description of the invention (1) Background of the invention 1. Field of the invention The present invention is related to the sputtering device * especially in the manufacture of semiconductor integrated circuits, etc. Related to the sputtering device used for thin film sinking. 2. Relevant technical description In the deposition of thin films using sputtering, especially in the manufacture of high-integrity semiconductor devices, it is extremely necessary to be used in the sputtering of thin film deposition steps. It is necessary to have a high orientation with excellent step coverage properties. A film is deposited at the bottom of the fine hole, that is, to improve the bottom coverage ratio. In keeping with this demand, improvements have been made so that a film can be deposited to allow sputtered particles to enter the fine hole at a small angle. One of the improvements is called aiming sputtering. Figure 10 shows a schematic diagram of the aiming sputtering device in the example of a conventional sputtering device. In the apparatus of FIG. 10, the cathode 2 and the substrate holder 3 are arranged so that they face each other in the vacuum chamber 1. The cathode 2 includes a magnet mechanism 4 and a landmark 5 located in front of the magnet mechanism 4 · a film deposited substrate 30 is placed in front of the substrate holder 3. A sight 6 is arranged in the space between the cathode 2 and the substrate holder 3. The structure of the sight 6 includes a plurality of small cylindrical components, forming a segment form, so that the height direction is perpendicular to the base 30 (hereinafter, this direction is referred to as the axial direction) * Therefore, the sputtering particles can be arranged in sections along the axial direction Multiple flow paths. This architecture is generally referred to as a "grid" or "honeycomb" architecture. Sputtered particles emitted from the landmark are distributed according to the law of cosine. Therefore, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm)] --------- ^ ----- --tr ------ m (Please read the precautions on the back before filling in this page) 32ι593 A7 __B7__ V. Description of the invention (2) Multiple sputtered particles enter the sight 6 at a large angle of incidence. However, 'most of these sputtered particles are formed on the wall surface of the fluid path of the sight 6'. The result is that the sputtered particles emitted from the sight 6 mainly contain particles with a small incident angle. As a result, only those with a small incident angle The sputtered particles collide on the substrate 30 'so the step coverage of the bottom of the fine hole formed in the surface of the substrate 30 is performed. In the above-mentioned aiming sputtering device, the sputtered particles deposited on the sight 6 reduce the cross-sectional area of the flow path of the sight 6 *. As a result, the number of sputtered particles that can pass through the sight 6 decreases with time. Therefore, the sputtering rate gradually decreases. Recently, it is called low-pressure long-distance sputtering, and the distance between the landmark and the substrate (hereinafter referred to as the TS distance) has increased (3 to 6 times more than the traditional device). This device has been developed as a sputtering Device, this device can prevent the above problems and has a high low pressure long distance sputtering. Park 1 1 shows a schematic diagram of low-pressure long-distance sputtering in another example of a sputtering system. In the apparatus of FIG. 11, the cathode 2 and the substrate holder 3 are arranged in the same manner as in FIG. 10. Opposite in the vacuum chamber 1, and place the substrate 30 in front of the substrate holder 3. Set this TS distance so that it becomes, for example, 150 to 360 mm. The pressure inside the vacuum tank 1 is set to be lower than the pressure in the conventional system to about lmTo r r or less. This reduced house force can be introduced, so that the average free diameter of the sputtered particles increases, and the sputtered particles are less scattered. Therefore, the sputtered sputtering of the sputtered particles is reduced, and many sputters on the substrate can be substantially perpendicular to the substrate The particles can collide, so the paper size can be changed to the Chinese National Standard (CNS) A4 specifications (210X297 mm) r —.1 ^ III, —installed IIII order-~ line-ί (please read the precautions on the back first (Fill in this page again) A7 B7_ printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. 5. Description of the invention (3) Coverage ratio at the bottom of the fine hole. In particular, for example, Japanese Patent Unexamined Case No. He i 7 -2 9 2 4 7 4 shows that when the diameter of the landmark is 2 5 Omm, the diameter of the base is 200 mm, the TS distance is 300 mm, and the When the force is 3 X 1 〇_2Pa, the bottom coverage ratio can be improved. As shown in Table 3 of this publication, when the TS distance increases, the film deposition rate can be greatly reduced, and the bottom coverage ratio is improved. As a result, for 256 rivers 1) 11; or greater (line width 0.25 / / 111, azimuth ratio 4: 6), the thin film deposition in the thin hole processing is more efficient, but it will cause problems for the throughput of low pressure and long distance sputtering. When the T S distance is reduced to increase the thin film deposition rate, the bottom coverage ratio is reduced, and it is difficult to apply this technique to 256Mbit or higher bit programs. In other words, in low-pressure long-distance sputtering, the film deposition rate and the bottom coverage ratio are in an exchange relationship, and they are not compatible with each other.

In addition, the sputtering process is further The requirements can be adapted to large-sized substrates. In the manufacturing process of the semiconductor device as described above, the size of the substrate tends to increase, so that more devices can be manufactured from a substrate and the production facility is improved. Moreover, in the manufacture of liquid crystal display devices, a sputtering process can be introduced into the glass substrate, and the size of the substrate can be enlarged to widen the display area. The relationship between the increased size of the substrate and the TS distance factor and the film deposition rate in the low-pressure long-distance sputtering is quite complicated. First, the increased size of the substrate creates a problem that in low-pressure long-distance sputtering Insufficient coverage of the bottom of the part far away from the center of the base or the peripheral masses. This problem will be explained using Figures 12, 13 (A) and 13 (B).

In the thin 1 1 hole 3 0 1 formed corresponding to the base 30 and the center of the surrounding parts, different methods of 1 1 (1) t 1 3 (B) deposited film β in the vicinity of the center of the base 3 0 t As shown in Figure 1 3 (A), order I at the bottom of the fine hole 3 0 1 nfc application of excellent step coverage properties deposited film 3 0 2 1 1 I • For comparison, in the surrounding area of the substrate 30 (which On the outside of the part with the same diameter as the landmark 1 1 1), the splash from the side of the central axis of the large incident angle — 1 line 1 The number of plating particles increases, and therefore the state of the fine hole 3 0 1 is (as shown in the figure 1 3 (shown as B)): A film 1 1 3 0 2 is deposited on the wall surface on the peripheral end side facing the base 3 0, but no deposit is deposited on the wall surface on the central axis and bottom surface side. 1 | On the inner surface of the contact hole In the example of barrier metal deposition, this state leads to a major disadvantage. When using a large substrate 9 the size of the landmark will increase with the increase of 1 L plus. 1 1 The problem of increasing the size of the substrate is quite complicated 9 and is entangled with the above-mentioned thin film deposition 1 1 rate incompatibility problem 9 thus making the problem more tangible deterioration.

Invention description (6) In Figure 16, the logo 0 and the surrounding black circles indicate the indication The center of the base. Near the bottom coverage ratio. In the two data sets, the data is arranged on the same line. This shows that the bottom coverage ratio on the surface of the base is maintained fairly uniform. The thin film deposition rate is similar to the thin film deposition rate in the arc sputtering device method, or about 600 angstroms per minute. That is, the thin film deposition rate reduces the bottom coverage ratio of the traditionally required N device by 1/3 or 1/4 · In comparison, when the TS distance is reduced to 2 6 Omm, the film deposition rate can be improved to 1 000 angstroms per minute. • As shown in Fig. 17, however, when the orientation ratio = 2 the bottom coverage ratio is reduced to About 28 to 35 percent. Even in this example, the bottom coverage ratio is higher than that of the arc sputtering method or 15%. From these results, it can be seen that when the size of the substrate increases or the diameter is 300 mm, for example, the bottom coverage ratio and the film deposition rate will be described below. Figure 18 shows the results of studies on the effect of substrate size enlargement on the bottom coverage ratio and film sink rate. In Fig. 18, the oblique lines indicate the cross-sectional shape of the corrosion in the landmark 5. First, as shown by circle 17, when the diameter of the landmark is 269 mm and the TS distance is 340 mm (Figure 18 (a)), an excellent bottom coverage ratio can be obtained. This design can also be used when the base 30 is smaller than the landmark and its diameter is 8mm. When the base 30 is larger than the landmark 5 and the diameter is 300mm, the landmark 5 is enlarged to a size This size is smaller than the size of the above substrate 30. In this example, in order to obtain a small bottom coverage ratio, the TS distance needs to be further increased. The paper size is applicable to the Chinese National Standard (CNS) A4 format (210X297mm).

Invention description (7) This can be used to illustrate the flight path of the N device particles of the most deeply corroded parts. In many sputtering processes, on the landmark area during the corrosion of the deepest corrosion site (hereinafter referred to as the corrosion area), a specific location in the radial direction of the landmark tends to be further corroded (hereinafter, this location It is called the deepest corrosion site), and the sputtered particles emitted from this site have a profound influence on the state of thin film deposition. In the case of planar magnet sputtering etc. (its current users), the surrounding shape formed by the corrosion rate. In many cases, the deepest corroded site has a surrounding shape. Figure 19, 20 shows the shape of the deepest corroded area. Figure 19 is a schematic perspective view of the magnet mechanism used in the conventional device * and Figure 20 is a perspective view of the cathode in the conventional device. In the device shown in FIG. 10 or 1 1, the magnet mechanism 4 arranged on the back of the pawn landmark 5 includes a cylindrical central magnet 4 1 2 which is fixed on the dish-shaped yoke 4 1 1, and A cylindrical peripheral magnet 41 3 surrounds the central magnet 4 1 2 while leaving a gap therebetween. The front surface of the center magnet 412 shows different magnetic poles and corresponding surrounding magnets 4 1 3. For example, the center magnet 4 1 2 forms an S pole, and the surrounding magnet 4 13 forms an N pole. In this example, the magnetic lines of force are emitted from the surrounding magnets 4 1 3 through the landmark 5 and leak out from the center of the surface of the landmark 5. FIG. 19 and 20 show the arc winding into the surface of the landmark 5- Location, and then the landmark 5 reaches the center magnet. The magnetic flux leakage lines of these magnetic forces follow the gap between the center magnet 412 and the surrounding magnets 413, so that the surrounding magnetic fields shown in circles 19, 20 are formed. In the sputtering process using the magnetic field function (such as magnetron sputtering), the electrons are captured by the magnetic field, which improves the efficiency of ionizing gas molecules. As a result, please read the note on the back.% The paper size of the bound and bound book is applicable to the Chinese National Standard (CNS) A4 specification (210Χ2ί »7mm) -10-322593 A7 B7 Printed by the Central Labor Bureau of the Ministry of Economic Affairs Fifth, the description of the invention (8) The rate of the sassafras 5 of ion sputtering, that is, the shape of the corroded area 50 corresponds to the shape of the magnetic field. In the above example (where the magnetic field of the peripheral area has been set), this area has a surrounding shape. In magnetron sputtering, electrons perform the movement of magnetons in the area where the electric field and the magnetic field are orthogonal, and the ionization effect can be maximized in this reference. In the configuration of Fig. 19 and 20, the orthogonal relationship between the electric field and the magnetic field can be established in the part of the magnetic leakage line of the magnetic force, and strong corrosion tends to occur below the bearing part. In addition, the deepest corroded part shows a peripheral shape in the receiving part of the magnetic arc-shaped magnetic flux line. As described above, the shovel particles are emitted from the deepest corroded part. As a result, the geometry of the deepest etched site can have a large effect on the state of the film deposition on the substrate. When the landmark 5 and the substrate 30 are coaxially arranged, as shown in Figs. 10 and 11, the deepest corroded part of the half surrounding area or half of the landmark 5 affects the corresponding half-rate film deposition on the substrate 30 However, it will not affect the other half of the area. This is because the other half of the base 30 is affected by the corrosion of the surrounding half of the landmark 5. The sputtered particles emitted from the deepest corroded part of the half of the circle will be described below. Among the sputtered particles, the collision of the sputtered particles near the center of the substrate 30 has the largest incident angle corresponding to the substrate 30. When the radius of the deepest corroded part is not greater than half the radius of the landmark 5, the substrate Sputtered particles that are partially collided with the surrounding area of 3 0 have the smallest angle of incidence • However, this state rarely occurs. In the example of Figure 18 (a), where the landmark is 2 6 9mm in diameter, when the deepest corroded part is separated from the central axis 2 0 7 0, please read the back note first

Therefore, the magnetic field of the second surrounding part above the surrounding area of the second S-pole magnet 4 2 4 • has a surrounding shape and does not intersect each other as shown in FIG. 3 The two corrosion areas 50 are formed by the magnetic fields of the two surrounding parts. The magnet mechanism 4 of this embodiment is rotated by the rotating mechanism 22, which will be described below. Actually, when the magnet mechanism 4 is static, the above-mentioned selective corrosion region 50 can be formed. When the magnet mechanism 4 rotates, the corrosion area 50 line rotates around the central axis, and thus the corrosion area 50 is distributed over substantially the entire surface of the landmark 5 (forming a single area). When the corrosion area 50 having the shape of the surrounding part is selected and formed on the landmark 5 without intersecting with each other as described above, the diameter of the deepest corrosion part of each corrosion zone 50 (when the deepest corrosion part is not circular, The shortest line connecting the two points on the surrounding parts) is always smaller than the diameter of the deepest corroded part caused by the Futong effect * wherein a single corrosion zone is formed in the traditional technology 50. When the diameter of the deepest corroded part is small, The incident angle of the sputtered particles is small without increasing the TS distance. Refer to Figure 4 for more details. Fig. 6 is a schematic cross-sectional diagram illustrating the function of the embodiment of Figs. 1-3 " In the shape of the corrosion area in the landmark 5 indicated by the hatched area in FIG. 4, when the substrate 30 is seen from the deepest corrosion position The position of the surface part of the substrate 30 that forms the maximum incidence angle can be made coaxial with the center part of the deepest corroded part of the peripheral part, as shown in FIG. 18. The incident angle 0 of the splashed ammonium particles from the deepest erosion site is obviously smaller than that shown in Fig. 18 '. A single etched area is formed in Fig. 18.

Description of the invention (i3) As described above, according to the configuration of the embodiment, the incident angle of the sputtered particles is relatively small. M does not increase the TS distance. As a result, the bottom coverage ratio can be improved to maintain the required thin film sink rate, and this embodiment is most suitable for making the actual thin film deposition technology, which is used for lower-substrate circuit with higher integration . When the gap between the two corrosion areas 50 is quite large, it can cause the maximum incidence angle to be reached at the position of the substrate 30 opposite to the gap. Therefore, the gap between the corrosion areas 50 can be set to a minimum. Theoretically, this gap does not More than half of the diameter of the deepest corroded part · In order to improve the bottom coverage ratio, the diameter of each deepest corroded part is preferably not greater than the diameter of the substrate · When the diameter of each deepest corroded part is equal to or greater than the diameter of the substrate 30, the incident angle of the sputtered particles The method is equal to or greater than this limit as described in the conventional technology. However, it can be considered that unless the landmark used is extremely larger than the base, or the base is extremely smaller than the landmark, this state will not occur. The diameter limit of the deepest corroded part corresponding to the TS distance depends on the azimuth ratio of the fine holes to be covered Figure 5 shows the relationship between the diameter of each of the deepest corroded parts and the azimuth ratio corresponding to the TS distance. As mentioned above, in the process of manufacturing an integrated circuit of 2 5 6Mb it or more, the azimuth can be 2 or higher. Introduce thin film sinking into the fine holes of the ratio * In the following, consider the film that sinks into the thin holes 30 in the azimuth ratio of 2 when the deepest corrosion site is equal to the TS distance • As shown in Figure 5, from the deepest corrosion site The sputtered particles pass through the opening end 303 of the hole to reach the end 304, which is at the bottom of the hole and is opposite to the end 303.

Description of the invention (14) 2 in the fine hole The thin film deposition has been limited to: (diameter of the deepest corroded part) = (TS distance) "When the diameter of the deepest corroded part exceeds the limit, the bottom coverage ratio is extremely low. In the thin-film sinking technology used in next-generation devices (where the azimuth ratio is 2 or greater), it is best to set the diameter of the deepest etched portion to be equal to or less than the T S distance. Next, the arrangement and overall operation of other parts in this embodiment will be briefly described. A system that can achieve a vacuum degree of about 10_βτ〇r Γ is used. In the thin film deposition process, a discharge gas such as argon is introduced into the vacuum tank 1, and thus the vacuum degree of about 0.03 mTorr is maintained, so that the sputtering particles can be prevented from scattering in a manner similar to the above-mentioned low-pressure force long-distance sputtering. Attach a valve to the wall of the vacuum tank 1. A transfer system (not shown in the figure) that can enter and exit the substrate 30 via a gate valve is provided. A gap (not shown in the figure) is juxtaposed with the vacuum tank 1 via the gate valve. The cathode 2 is arranged in the above manner. In this embodiment, a rotating mechanism for rotating the cathode 2 about the central axis is added. The rotating mechanism is used to form uniform corrosion on the landmark 5 and includes a rotating shaft. This glaze is connected to the back of the yoke 4 2 1, and Coaxial with the central axis 2 0, the driving source 4 2 1 for rotating the rotating axis 2 2 1 · As mentioned above, the landmark 5 near the central axis 20 is included in the corrosion zone 50 • As a result, this The parts can prevent the remaining parts from corroding when the magnetic cone mechanism 4 rotates. Therefore, the use efficiency of the landmark 5 is further increased. The substrate holder 3 is provided with a mechanism that can absorb and hold the substrate 30 by electrostatic attraction, and a substrate 30 can be held during the film sinking process ---------- ^ --- --- 、 tT ----- ΊΦ (please read the precautions on the back & write this page first) A paper size is applicable to China National Standard (CNS) A4 specification (21〇X297mm) -17-52 ^ 593 A7 B7 5. Description of the invention (15) Heating mechanism heated to a fixed temperature. If necessary, the substrate 30 can be biased to the substrate holder 3 by biasing the power supply printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. The gas introduction system 7 introduces the gas that needs to be released into the vacuum tank 1 during sputtering, and this system includes a pipeline 7 1, which is connected to a gas graph column (not shown in the figure), and a flow controller that connects the pipeline, a Valves, etc. When introducing a reactive sputtering device, a reactive gas can be introduced to release gas mixture. Cathode power supply 21 adds a given negative DC voltage to the cathode 2, or a radio frequency voltage required for the sputtering device to discharge. Generally, when the landmark 5 is made of metal, a negative DC voltage is added, and when the landmark is made of a medium, etc., a radio frequency voltage is added. When there is no bias, the vacuum chamber and the substrate holder are grounded, so the voltage can be maintained at the ground level. The high voltage added to the cathode 2 generates an electric field between these components and the cathode 2, and this electric field can be discharged during sputtering. In the sputtering device configured by the present invention, the substrate 30 is transferred into the vacuum tank 1 via a gate valve (not shown in the figure) by a transfer system (not shown in the figure), and placed on the substrate holder 3 Secondly, the cathode power source 2 1 is applied so that the cathode 2 can be pressurized * and the gas introduction system 7 is operated so that the gas can be introduced into the vacuum chamber 1, so that the phenomenon of sputtering discharge can occur as described above. As a result, the sputtered particles radiate from the sassafras 5 and reach the substrate 30 to be deposited, where they are introduced into the thin film Shen Zhen. As described above, in this embodiment, because a small-diameter corrosion area is formed on the landmark 5 5 0, the angle of incidence through the center of the sputtering device of the substrate 30 is quite similar. Therefore, compared with the traditionally used system, the bottom coverage ratio of the fine hole can be significantly improved. ---------- ^ ------.

Description of the invention (16) Next, the second embodiment of the present invention is explained below. Fig. 6 is a schematic plan view showing the configuration of the cathode in the second embodiment of the present invention. In the second embodiment, three surrounding magnetic fields are set, as shown in FIG. 6. In particular, in the second embodiment, the magnet mechanism 4 constituting the cathode 2 includes an N-pole magnet 432 and an S-pole magnet 433, and the S-pole magnet 433 is fixed to a yoke 4 3 1. The shape of the N-pole magnet 4 3 2 includes a ring-shaped outer peripheral part, which can be extended along the peripheral end of the yoke 4 3 1, and two extendable linear parts, so the internal space surrounded by the outer peripheral part becomes three Spaces. The S-pole magnets 4 3 and 3 are located in the center of the three spaces inside the outer peripheral parts. The magnetic fields of the three surrounding parts form three corrosion areas 50 on the landmark 5 without intersecting each other, as shown in FIG. 6. Therefore, in the second embodiment, the diameter of the deepest corrosion part is reduced, so it can be as the first One embodiment completes the effect of reducing the incident angle. In comparison with the first embodiment, in this embodiment where three surrounding magnetic fields are set, the diameter of the corrosion zone 50 can be made smaller than that with two surrounding magnetic fields.

V. Invention description (20), the current level of the field coil 447 on 455, 456, 457 and 458 can be controlled so that the current level can be increased considerably. The current regulator 4 4 9 such as the use of a thyristor can turn on and off the current supply during a fixed period, and the on / off period can be adjusted according to the signal from the programmable controller 4 5 0. The supply of eight field coils 4 4 7 wound on the auxiliary core components 451, 452, 453, 454, 455, 456, 457 and 458 has a period of current comparable to the four fields wound on the coil component 4 4 1 in the coil 7 The current cycle on the coil 4 4 7 is longer. This makes the magnetic flux density of the magnetic flux leakage lines due to the magnetic force generated by the auxiliary core components 451, 452, 453, 454, 455, 4 5 6, 4 5 7 and 4 5 8 quite high, thus increasing the corrosion around the landmark 5 Sex. As a result, the deposition rate of the thin film around the substrate 30 is improved, and the uniformity of the slab with a thick distribution of thin film deposition is increased. The independent control of the supply current level can be introduced according to the following methods: the two electromagnet groups that set the magnetic field around the two parts are independently controlled, or all the electromagnets are independently controlled. As long as at least two groups can be controlled independently, it is possible to add any kind of magnetic field adjustment function. In the above embodiment, the number of magnetic fields in the surrounding area is two or three. In addition, the number can be four or 5. When the number of magnetic fields in the surrounding parts is large, the incident angle of the sputtered particles at the same T S distance is generally small. Therefore, it is better for the magnetic field around Da Dong to improve the bottom coverage ratio. The rotating mechanism 22 can rotate the landmark 5 on the magnet mechanism 4. The central axis 20 of the magnet mechanism 4 can deviate from the landmark 5 by a certain distance, so that the magnet please read the note on the back.

Description of Invention (2l) Institution 4 can revolve around the central axis of landmark 5 Turn. In this manual: the term " surrounding shape " has a broad meaning, and has a round shape, an oval shape, an oval shape, a polygonal shape, and unevenness (such as a wave shape). There is no need to form a complete circuit around it, and it may contain any incomplete parts. Even those with a partial interruption in the surrounding magnetic field in the surrounding corrosion blue 50 can still be used, such as uneven thickness in the deposited film. The deepest corroded site does not necessarily require a linear profile, and can be band-shaped or a substantial broad side. The best from the highest part to the shallowest part can be used as the deepest corroded part. The deepest corroded part is a conceptual part that can be used as a part to determine the corroded area, which has the deepest influence on the film deposition and is suitable for The degree of influence is determined. Corrosion is placed at a location where it can be corroded by the magnetic field. A very small number of ions can diffuse to the outside of the corroded area and reach a substrate that can penetrate a landmark. Over time, therefore, extremely shallow corrosion can be performed on the outside of the corrosion area • However, this corrosion does not affect the state of the film sinking, so it can be judged that this corrosion is not a substantial corrosion • When it is assumed to be in the corrosion area When the average corrosion rate is 100%, the area with a corrosion rate of 5% or less is considered not to be an actual corrosion area.
