Further, a rotating shaft 26 that is rotatably mounted around the vertical axis X -11 - 1353647 - at a traveling end portion of the movable table 21 and a motor disposed on the movable table 21 via the two belts 28 27 is decelerated and interlocked, and by the action of the motor 27, the rotating shaft 26 is rotated at a low speed. Then, as shown in Fig. 3, the support arm 22 is slidably adjusted to support the lower portion of the support member 29 projecting downward from the rotary shaft 26. Thus, by the sliding adjustment of the support arm 22, the radius of rotation of the cutting edge 12 can be changed and adjusted corresponding to the radius of the wafer. The bracket 30 is fixed to the travel arm of the support arm 22, which is mounted to support the cutter unit 23. The cutter unit 23 is a rotation member 31 rotatably supported on the bracket 30 ® around the longitudinal axis Y, and a support bracket 32 connected to the vertical wall of the end portion of the 'rotation member 31, a cutter supporting member 33 coupled to the side surface of the support bracket 32, a movable bracket 34 slidably supported by the cutter supporting member 33, a cutter holding portion 35 attached to the movable bracket 34, and the like Composition. The cutting edge 12 is screwed to the side surface of the cutter holding portion 35 so that the back surface of the cutting edge is aligned with the longitudinal axis Y. Here, as shown in Fig. 4, the operation flange 38 which is integrally rotated with the rotation member 31 by the engagement of the long hole 36 and the two pins 37 is disposed above the rotation member 31. When the operation flange 38 is rotated by the air cylinder 39, the entire cutter unit 23 is disposed at a position around the longitudinal axis Y with respect to the support arm 22, that is, an angle with respect to the moving direction of the cutting edge 12 can be predetermined. Small range adjustment. Further, the bracket 30, the rotating member 31, the long hole 36, the operating flange 38, and the air cylinder 39' correspond to the moving angle adjusting mechanism of the present invention. As shown in Figs. 5 to 7, the cutter support member 33 is rotatably coupled to the support bracket 32 by the guide -12-1353647. The guide mechanism 40 is fitted with a partially arc-shaped sliding projection 42 projecting from the side surface of the support bracket 32 in a portion of the arc-shaped sliding guide groove 41 formed on the side surface of the support bracket 32. With the center of curvature of the sliding guide groove 41 and the sliding protrusion 42 as a fulcrum, the cutter supporting member 33 can be slidably rotated with respect to the support bracket 32 within a predetermined range (for example, 30°). Then, the curvature center P of the partial arc-shaped sliding guide groove 41 and the sliding protrusion 42 is set at the cutting position A of the cutting edge of the cutting edge 12, and the t-grain at the cutting edge 12 is adjusted by the sliding adjustment. The angle of intersection α in the radial direction (see Fig. 8) can be adjusted and adjusted with respect to the surface of the wafer. On the bottom surface of the concave sliding guide groove 41, a partial arc-shaped long hole 43 having the same curvature is formed, and from the back surface of the support bracket 32, the two bolts inserted into the long hole 43 are screwed to When the cutter supports the member 33, the cutter supporting member 33 can be fixed at an arbitrary sliding position. Further, a memory body (not shown) is engraved on the bottom surface of the slide guide groove 41 at a predetermined angular pitch (in this example, 2°), and the sliding position I of the sliding protrusion 42 embedded in the groove 41 can be confirmed. That is, as shown in Fig. 7, a mark 45 is attached to the bottom surface of the slide guide groove 41 and the surface of the opposite slide guide groove 41, and the mark 45 is referred to by the movement position as the slide protrusion 42 slides. And the memory of the sliding guide groove 41, the intersection angle of the wafer radial direction of the cutting edge 12 with respect to the wafer surface can be understood, and the cutter supporting member 33 is horizontally slidably coupled to the cutter supporting member. A tension spring 46 is stretched between the movable brackets 34, and the movable bracket 34 is slidably urged toward the center of rotation of the cutter. However, -13-1353647 • The tension spring 46 is equivalent to the elastic means of the present invention. Next, a series of basic operations of adhering the protective tape T to the surface of the wafer W using the apparatus of the above embodiment will be explained. When the attaching command is issued, first, the robot 2 of the wafer transport mechanism 3 moves toward the wafer cassette C mounted on the wafer supply/recovery unit 1, and the wafer holding unit 2a is inserted into the wafer. In the gap between the wafers W in the crucible C, the wafer W is sucked and held from the back surface (lower surface) at the wafer holding portion 2a, and the taken wafer W is transferred onto the alignment stage 4. The wafer W placed on the alignment stage 4 is aligned by a groove formed on the outer circumference of the wafer w', and the wafer W after the alignment is again carried out by the robot 2 and loaded. Placed on the clamping table 5. The wafer W placed on the chuck 5 is held in a state of being aligned so that its center is located at the center of the chuck 5. At this time, as shown in Fig. 9, the pasting unit 8 and the peeling unit 10 stand by at the initial position on the left side and the cutting edge 12 of the tape cutting mechanism 9 at the initial positions on the upper side. Next, as shown by the imaginary line in Fig. 9, the bonding roller® 17 of the pasting unit 8 is lowered, and the protective tape T is pressed downward by the bonding roller 17, and the wafer W is directed forward (9th) In the figure, it is the right side). By this rotation, the protective tape T is adhered to the entire surface of the wafer W (refer to Fig. 10). Next, when the pasting unit 8 reaches the end position, as shown in Fig. 1, the cutting blade 12 which stands by the upper portion descends and passes through the protective tape T which is inserted into the cutter moving groove 13 of the clamping table 5. When the cutting edge 12 is lowered to a predetermined cutting height and stopped, as shown in Fig. 12, the support arm 22 is rotated in a predetermined direction, and along with this, the cutting edge 14-1353474.12 is wound around the longitudinal axis X. The movement is moved so that the protective tape T is cut along the outer shape of the wafer. At this time, the cutting blade 12 is pressed against the outer circumference of the wafer w by the sliding force generated by the tension spring 46, and is moved along the outer shape of the wafer w. When the cutting of the outer shape of the wafer w is completed, as shown in Fig. 12, the cutting edge 12 is raised to the original standby position, and then the peeling unit 10 is moved toward the front side while being on the wafer W. The unnecessary tape 切断 that has been cut and left is wound and peeled off. When the peeling unit 1 〇 reaches the completion position of the peeling operation, the peeling unit 10 and the pasting unit 8 move in the opposite direction and return to the initial position. At this time, the unnecessary tape Τ' is wound around the take-up reel 20, and a certain amount of the protective tape 拉 is pulled out from the tape supply portion 6. When the sticking operation is completed, after the suction in the chuck 5 is released, the wafer W which has been pasted is transferred to the wafer holding portion 2a of the robot 2, and inserted into the wafer supply/recovery portion 1 It is recycled in the circle C. Using the above method, the tape processing is completed once, and then the above operation is repeated in sequence. However, the present invention can also be carried out using the following modes. (1) In the above-described guide mechanism 40, a slide protrusion 42 may be provided on the support bracket 32, and a slide countermeasure groove 41 may be provided in the cutter support member 33. (2) The guide mechanism 40 may be configured by using a slide guide rod that is bent in an arc shape with the cut portion of the cutting blade 12 as a center, and a member that is slidably fitted along the rod. -15- 1353647 The present invention may be embodied in other types of stomachs without departing from the spirit and essence of the invention, and the scope of the invention should be construed in reference to the appended claims.
