The present invention is also directed to a method of grinding the back surface of an article prior to application of the film to a surface prior to application. The invention is also directed to a method of forming a semiconductor wafer, the method of forming a semiconductor wafer comprising the step of grinding the back surface of the wafer. [Prior Art] In the field of manufacturing a semiconductor integrated circuit, a method of manufacturing a plurality of semiconductor wafers is known, in which a protective film or a protective film is formed after a circuit is formed on a surface of a wafer of a predetermined thickness or In the case where a glass plate is applied to a surface on which a circuit pattern is formed (hereinafter referred to as a circuit side), the thickness of the wafer is uniformly reduced by grinding the surface of the wafer in the side opposite to the circuit side and cutting Thinned wafers (generally referred to as dicing) are divided to obtain a plurality of semiconductor wafers. For example, Japanese Unexamined Patent Publication (Kokai) No. 2005-1502W discloses a semiconductor surface protection method and a semiconductor surface protection sheet which permits back grinding of a semiconductor wafer to an ultra-thin wafer. . The semiconductor B has a high protrusion (such as a solder bump) on the side of the polishing circuit. The semiconductor surface protection method disclosed in Japanese Unexamined Patent Publication No. Hei No. Hei-5-150235 comprises the steps of: laminating a polymer film material to the circuit side of a semiconductor wafer via a surface protective layer 'The surface protective layer is Fluid at room temperature or fluidized by heating and hardened after exposure to radiant energy or by heating; and solidification of the protective sheet of the semiconductor I60620.doc 201246341. Regarding the method of using the surface protective sheet, there is a description that the surface protective sheet can be laminated by bringing the surface protective sheet into close contact with the circuit side of the semiconductor wafer after heating or during heating. The sheet can be brought into close contact with the circuit side of the wafer in the vacuum chamber. This method can be used to achieve a perfect laminate that does not include bubbles. In the case where the circuit side of the wafer is protected by the surface protective sheet, the wafer can be thinned by polishing the surface of the wafer opposite to the circuit side. After the wafer obtained by the back grinding step is fixed by bonding the finished abrasive surface to the dicing sheet, the obtained wafer is transferred onto the diced sheet by removing the surface protective sheet by peeling off' 'And send the obtained wafer to the dicing step. A method for effectively preventing the flattening in a dicing block in a method of manufacturing a semiconductor wafer, including a dicing step of a semiconductor wafer, is disclosed in Japanese Laid-Open Patent Publication No. 2005-159155.

The thickness of the bonding layer 18 after the liquid adhesive 16 is solidified is not particularly limited, but is preferably in a range permitting filling of the unevenness of the first surface 10a and flattening the film 12, for example, at 10 It is in the range of μηι to 15〇μηη, and more preferably in the range of 20 μm to 100 μηη. For the component group as described above, the liquid adhesive 16 is disposed on the first surface 10a of the article 10 or the film 12 in the next step of the method of coating the film (or the method of polishing the back surface). Before the surface 123. The liquid adhesive 16 can be disposed on the first surface 10a of the article 10 or the front surface 12& of the film 12 by dropping or coating the liquid adhesive 16 with a suitable device. In the configuration shown, the object 1 is placed on the stage 20 with the first surface 10a facing up (Fig. 4(a))' and a sufficient amount of the liquid adhesive 16 is disposed on the object 10 In the region of the center axis 1〇d of the first surface 10a (Fig. 4(b)). When the liquid adhesive 16 is disposed on the first surface of the object 1160160620.doc -18-201246341, the liquid can be liquidated by, for example, rotating the object 10 about its central axis 1〇d or vibrating the object The adhesive 16 is uniformly spread over the entire first surface 10a. On the other hand, the frame member 丨4 is firmly attached to the film 12 along the periphery 12c of the film bundle 2 (Fig. 3(b)). In the drawings, the frame member 14 is uniformly fixed to an annular region along the entire periphery 12c of the weir surface 12a of the film 12. The frame member 14 can be fixed by various bonding members such as an adhesive, double-sided adhesive bonding, fusion bonding, and the like. In the configuration shown, the same liquid adhesive as the liquid adhesive 16 is used as the bonding member, and the second surface Mb of the frame member 14 is firmly fixed by the bonding layer 22 formed by solidification of the liquid adhesive 16. To the front surface 12a of the film 12 (Fig. 3(b)). This liquid adhesive can be placed in a continuous line along the front surface of the membrane 藉2 by using a suitable nozzle! The annular region of the periphery 12c is disposed on the second surface 14b of the frame member 14. The liquid adhesive can be configured by using a stationary nozzle while rotating the membrane 12 or the frame member 14 about the central axis 12d or 14e, or by using an automated machine such as a robot. The circular track is moved to the stationary film 12 or the frame member 14. Next, the article 10 and the film 12 are disposed in opposite positions, wherein the first surface 10a and the front surface 12a are opposed to each other. The area of the film 12 along the periphery 12c (and therefore the frame member 14) extends outwardly from the article 1〇. Both the first surface i〇a and the front surface 12a are in contact with the liquid adhesive 16 (Fig. 4(c)). Next, the liquid adhesive 16 is widely spread between the first surface i〇a of the article 10 and the front surface 12a of the film 12 (圊4(d), Fig. 4(e)). Since the frame member is "fixed to the media 2" uniformly along the periphery 12, the central portion 12e of the film 12 located inside the frame 14 of the frame 160620.doc • 19· 201246341 can be maintained by the frame member 14 (Fig. 3(b) )) is in a fully extended state (i.e., no twisted state). Therefore, the first surface 10a of the article and the front surface 12a of the film 12 can be placed in contact with the liquid adhesive 16 in substantially parallel relationship with each other. The agent 16 solidifies to firmly adhere the film 12 to the first surface 10a of the article 10 (Fig. 4(f)). For example, if the liquid adhesive 16 is a UV curable adhesive, it is from the side of the back surface 12b. The film 12 is irradiated with UV radiation to solidify the liquid adhesive 16. Since the liquid adhesive 16 has the material properties as described above, the liquid adhesive 丨6 fills the convex portion formed on the first surface 10a of the article 丨a gap between the turns or a linear groove (not shown) for the "cutting and re-polishing process", and a bonding layer 18 not including bubbles is formed between the object (wafer) 1 and the film 12 ( The bonding layer 18 stabilizes the front surface 12a of the film 12. Attached to the entire first surface 10a' of the object 1〇 so that the object 10 and the film 12 can stably support each other. In the illustrated construction, when the liquid adhesive 16 is solidified, the object 1〇, the film 12 and The frame members 14 are disposed substantially coaxially with each other. Further, an annular gap having a substantially uniform size is formed between the periphery 1 〇c of the article 1 与 and the inner circumference 14c of the frame member 丨 4 (Fig. 2, Fig. 3 (b In the configuration as described above, the fixing of the frame member 14 to the film 12 may be performed before the first surface 10a of the article 1 and the front surface na of the film 12 are brought into contact with the liquid adhesive 16. Alternatively, the fixing step may be performed at the same time as or after the first surface 10a of the article 1a and the surface i2a before the film i2a is contacted with the liquid adhesive 16. The same liquid adhesive 16 is used. The frame member 14 is fixed to the structure of the film 12, and the liquid adhesive 16 can be disposed on, for example, the entire front surface 12a of the film 12 by coating or the like, 160620.doc -20 201204641. The first surface 10a is in contact with both the front surface 12a of the film 12. The body adhesive 16 can also contact the second surface 14b of the frame member 14 with the liquid adhesive 16 at the same time or a little before or after the step. In this state, the entire liquid adhesive 丨6 can be solidified. The bonding layers 18, 22 are formed to adhere the film 12 to both the article 1 and the frame member 4. In this case, it is necessary to perform the following steps in a vacuum environment: bringing the article 10, the film 12 and the frame member 14 into contact with the liquid The step of adhering '丨6' and the step of solidifying the liquid adhesive 16. All of the above steps (including the steps of contact and solidification) can be performed in a vacuum environment. In the method having the configuration of the coating film as described above, since the frame member 14 having rigidity higher than the rigidity of the film 12 is fixed to the film 12' along the periphery i2c, the film located inside the frame member 丨4 can be maintained The central region 12e of the crucible 2 is in a substantially undistorted state. Therefore, the first surface 10a of the article 1 and the front surface 12a of the film 12 can be disposed substantially parallel to each other and can contact the liquid adhesive 16. Since the liquid adhesive 16 is used as a bonding member for bonding the film 12 to the object 1 , various irregularities of the first surface 10a of the article 10 can be filled by the liquid adhesive 16 to achieve the liquid. The flatness of the film 12 after the adhesive 16 is solidified. Further, a bonding layer 8 substantially free of air bubbles can be formed between the object 10 and the film 12. This bonding layer 18 can stably maintain a high adhesion strength for a long period of time. Regarding the method of coating a film as described above, the film 12 can be accurately applied to the article 1 by using a simple technique. In the case where the film 12 is firmly attached to the first surface 10a of the article 10 by using a method of coating a film as described above, in the method of polishing the back surface, The article 10 and the film 12 are picked up from the table 20 together with the frame member 14. After the combination is reversed, the combination is placed on the other stationary platform 24 with the second surface l〇b of the article facing up (Fig. 3(b)). The object 10 and the film 12 are fixedly supported on the stationary stage 24 inside the frame member 14 by using a holding member such as a vacuum suction device. In order to eliminate unnecessary stress applied from the frame member 14 to the film 12 and to maintain the flat form of the film 12, the frame member 14 can be held in a state where the frame member 14 is fixed to the article 1 and the film 2. In this state, the entire second surface 10b of the article (7) is ground by a grinding device (not shown) to form a flat machined surface 23(c)). In the method of polishing the back surface having the configuration described above, since the first surface 10a of the article 10 is protected by the film 12, it can be reduced as compared with the method of using a glass plate for protection. cost. Since the frame member 14 having rigidity higher than the rigidity of the film 12 is fixed to the film 12 along the periphery i2c, the central portion 12e of the film 12 located inside the frame member 14 can be kept substantially free of distortion. The first surface i〇a of the object 1〇 and the front surface 12a of the film opening may be disposed substantially parallel to each other, and may contact the liquid adhesive 16 and may be quickly performed by the treatment frame member “for the abrasive article 10 The first surface-preparation of the surface l〇b (for example, reversing it, placing it on a stationary platform, etc.).
