Description
The present invention relates to a braking device for dividing a wafer into individual chips.
A device such as IC or LSI is divided by the line to be divided and the wafer formed on the surface is divided along the line to be divided so as to be divided into individual chips to which the device is attached. As a method of dividing the wafer, a laser beam is irradiated from the surface side of the wafer along the line to be divided along the divided line to form a modified layer inside the wafer. Thereafter, a braking device having a blade is used, Thereafter, there is a method of dividing the wafer into individual chips starting from the modified layer by pressing the wafer with the blade (for example, refer to Patent Documents 1-3 below).
When dividing the wafer, a tape is attached to a ring-shaped ring frame having an opening at its center so as to prevent the individual chips from being scattered, and one side of the wafer is upwardly exposed to the tape exposed from the opening, So that the wafer is supported by the ring frame through the tape.
However, in order to divide the wafer along the line to be divided by pressing the blade, a line-shaped space is formed on the holding surface of the chuck table for holding the wafer so that the line to be divided of the wafer is not supported, Is pushed into the space to be widened. Therefore, it is not possible to perform the dividing process using the same chuck table for wafers having different intervals of the lines to be divided.
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to divide wafers having different spacings of lines to be divided by using the same chuck table in a breaking apparatus for dividing a wafer by pressing.
A first invention is a braking device for forming a chip by dividing a wafer along a line to be divided along a line to be divided, the braking device comprising: an adhesive tape in which the opening of the ring frame having an inner diameter larger than the outer diameter of the wafer is sealed, A chuck table for holding a workpiece formed by adhering a wafer having a dividing point of one line type formed thereon, a pressing member for pressing the wafer held by the chuck table along the line to be divided, A pressing means for pressing the wafer against the wafer held by the chuck table by the pressing member so as to approach and separate the pressing member in the vertical direction, And the chuck table is provided with a porous plate And a holding section for holding the ring frame. The workpiece set is held by the chuck table, and the wafer is pressed and divided by the pressing member along the line to be divided.
In the braking device, the top surface of the ring frame held by the holding portion and the tip end portion of the pressing member are pressed against the suction surface by pressing the wafer held on the suction surface through the porous plate with the pressing member It is preferable that the front end portion of the pressing member which is approached is a height which does not contact the upper surface of the ring frame.
A second aspect of the present invention is a chuck table used in the braking device, wherein the suction surface of the chuck table is provided with a porous layer formed so that at least a region holding the wafer is depressed by the pressing member, So that the wafer can be divided by pressing the wafer along the line to be divided by the pressing member.
The braking device of the present invention comprises a chuck table for holding a workpiece in which a ring frame and a wafer are integrated through an adhesive tape, a pressing member for pressing the wafer along the line to be divided of the wafer held by the chuck table, When the wafer held on the suction surface of the chuck table is pressed by the pressing member, the porous plate is recessed along the line to be divided along with the wafer to be pressed. Therefore, It is not necessary to form a line-shaped space along the planned line to be divided.
Therefore, the wafer can be surely divided along the line to be divided, and even if a wafer having a different spacing on the line to be divided is held on the suction surface through the porous plate, the wafer can be divided by the pressing member.
When the upper surface of the ring frame held by the holding portion and the tip of the pressing member are pressed by the pressing member against the wafer held on the suction surface through the porous plate, Since the tip portion of the member is a height that does not contact the upper surface of the ring frame, the pressing member does not contact the ring frame.
Therefore, it is not necessary to use a ring frame having a size larger than the size of the wafer, so that the apparatus can be prevented from becoming larger.
The chuck table of the present invention has a porous layer which is depressed by the pressure of the pressing member on the suction surface of the chuck table and the porous layer is recessed along the line to be divided by the pressing of the pressing member, Chip can be divided into individual pieces.
