[Previous technology] During the wafer manufacturing process, metal, interlayer, and semiconductor thin film layers need to be repeatedly deposited on a substrate, for example, a silicon to gallium substrate is sputtered to a metal layer. The general deposition process is performed in a vacuum processing chamber. There are two common methods, physical vapor deposition and chemical vapor deposition, which can stack the film layers of insulating and non-insulating materials on the surface of the substrate. FIG. 1 is a schematic diagram of a conventional clamping ring. The clamping ring 10 is a metal ring-shaped object, and the contact surface 14 on the inner edge thereof abuts the peripheral edges of the active surface (surface of the substrate 12). A lip portion 16 adjacent to the contact surface 14 is provided on the innermost side of the clamping ring 10, and a further inclined surface 17 is embraced outside the contact surface 14. In the vacuum processing chamber of the Shenji process, the passive surface of the substrate 12 is fixed or adsorbed by a liftable support base 18, and the contact surface 14 of the clamping ring is pressed against the edge of the substrate 12, as shown in picture 2. ® 2 is a schematic cross-sectional view taken along the cross-section line. Since the contact surface 14 directly covers the active surface of the substrate 12, there are some problems in the deposition process. First of all, the clamping ring 10 and the surface of the substrate will also accept the deposited material. These deposits will form a bridging layer at the junction of the tight ring ^ and the substrate 12, so the substrate i2 will adhere to the clamping ring. . Although the inclined surface 17 extends outward at a slope, the bridging phenomenon is still unavoidable because the bottom portion is too close to the circumference of the substrate 12. Dang Shen

However, at this time, the edge of the substrate 12 is still adhered to the clamping ring, so it may be pulled and cause fragmentation. Secondly, the clamping ring 丨 0 covers the edge portion of the active surface of the substrate 12, so it will reduce the actual available surface of the substrate ι2, that is, the wafer edge will have more area or incomplete crystal grains. Knowing the above, 'the market urgently needs a clamping ring that can effectively hold the substrate but does not adhere to each other'. On the other hand, it is also necessary to increase the actual available area on the substrate to generate a larger number of grains. . [New content] The main purpose of this creation is to provide a clamping ring for semiconductor devices, which can effectively clamp the edge of the substrate during the wafer manufacturing process, and reduce the area where the circuit cannot be formed due to clamping. This creation is a clamping ring for semiconductor equipment, which can clamp and fix the edge of the substrate during the wafer manufacturing process. The clamping ring includes a ring-shaped body. The inner edge of the ring-shaped body has a plurality of first inclined surfaces. The diameter of the bottom of the first inclined surface is preferably at least 4 cm greater than the diameter of the substrate. The clamping ring additionally has a plurality of second inclined surfaces that are alternately arranged in a tooth shape with the plurality of first inclined surfaces. The diameter of the bottom of the second inclined surface is preferably at most greater than the diameter of the substrate. Another contact surface is adjacent to the first inclined surface and the second inclined surface at an obtuse angle, and the contact surface can be pressed just above the edge of the substrate. Another lip is located at the innermost edge of the clamping ring and is adjacent to the non-coplanar contact surface, so there is still a gap between the lip and the substrate. In addition, the inner edge of the ring body of the clamping ring can replace a continuous inclined cone surface H: \ HU \ LGC \ Ruiyun Technology \ 90529 \ 90529.〇〇〇-6- M256582 Two inclined surfaces, the diameter of the bottom of the inclined cone surface is at most larger than the diameter of the substrate 丨 cm. At least three contact surfaces are adjacent to the oblique cone surface at an obtuse angle, and the contact surfaces can be pressed just above the edge of the substrate. Another lip is located at the innermost edge of the clamping ring and is adjacent to the non-coplanar surface and the oblique cone surface, so there is still a gap between the lip and the substrate. [Embodiment] FIG. 3 (a) is a schematic diagram of a first preferred embodiment of the present clamping ring. The clamping ring 30 includes an annular body 3 and an inner edge of the annular body 31 connected to a plurality of first inclined surfaces 34. The bottom diameter of the first inclined surface 34 is preferably larger than the diameter of the substrate by 4 cm, and the plurality of second inclined surfaces 35 and the plurality of first inclined surfaces 34 are arranged in a staggered manner, and the diameter of the bottom of the second inclined surface is " It is preferably at most larger than the diameter of the substrate 丨 cm. A first-inclined ... second inclined surface 35 is adjacent to each other at a pure angle, and the contact surface is just pressed onto the edge of the substrate 12 'as shown in Fig. 3 (b ). A lip 32 is located at the innermost edge of the "30" and is adjacent to the non-coplanar miscellaneous contact surface 33, so there is still a gap between the lip 32 and the substrate 12. Figure 3 ( b) is a schematic cross-sectional view of fit 3⑷ along the 2-2 section line. From this figure, it can be clearly observed that only the second slope 35 is close to the periphery of the substrate 12 '. Therefore, the bridging phenomenon is limited to the second slope 35 and ⑽12. It will happen at the junction, that is, the problem of the sticking sheet on the side of the substrate 12 will be greatly improved. Assuming that the diameter of the substrate 12 is eight inches (200 mm), the diameter of the bottom of the first bevel μ is recommended to be 20 () .58 With, it is recommended to use 204.58 colors relative to the bottom diameter of the second slope. There are eight second slopes 35 in Figure 3, but the actual H: \ HU \ LGC \ Ruiyun Technology \ 90529 \ 90529.000 M256582 The second bevel 35 needs to be set at three places, so the substrate 12 can be accurately positioned. Figure 4 (a) is the creative folder Schematic diagram of the second preferred embodiment of the tightening ring. The refreshing ring 40 includes a ring-shaped body 41, and the inner edge of the ring-shaped body 41 has a continuous oblique tapered surface 43 instead of the first oblique surface 34 and the second oblique surface of the tooth arrangement of the previous example. 35. The diameter of the bottom of the inclined tapered surface 43 is preferably at most 1 meter larger than the diameter of the substrate. The clamping ring 40 has at least three contact surfaces 42 adjacent to the inclined tapered surface 43 at an obtuse angle. The contact surface 42 can be pressed on the edge of the substrate. Another lip 44 is provided on the innermost edge of the clamping ring 40 and is adjacent to the non-coplanar contact surface 42 and the oblique cone surface 43. In this way, there is still a gap between the lip 44 and the substrate 12, which can help the vapor deposition material pass through and make the film uniform. Figure 4 (b) is a view along Figure 4 (a). 3-4 is a schematic cross-sectional view of the section line, in which the lip shaw 44 and the contact surface 42 are shown in a step-like shape. The angle between the inclined tapered surface 43 and the horizontal plane (or the surface of the substrate 12) is preferably 80 degrees, and the bottom diameter thereof is recommended to be 200.58 mm. When the horse substrate 12 and the clamping ring 40 are close to each other, the contact surface 42 can be pressed together. At the edge of the substrate 12. As shown in FIG. 4 (d), the contact surface 42 'has an angle relationship with the horizontal plane instead of being parallel, and a preferred angle value is 4 degrees. The oblique cone surface 43, and the lip 44, The same size in the figure (c) can still be maintained, and the lip 44 can be changed to a bevel like the contact surface 42.
