Description of the invention (2) The porcelain substrate 61 is placed on a hard rubber layer 62, wherein the surface of the ceramic substrate 61 with the separation slit 64 faces the hard rubber layer 62 'and hits the ceramic substrate 61' with a hard rubber body 63. It is broken along the separation gap 64, but the hard rubber layer 62 is a plane so that the reverse force application point is not obvious and is too close to the impact point of the hard rubber body 63 in the forward direction, which makes the ceramic substrate 61 difficult to break or requires a comparative application. The large impact force 'makes the broken cross section of the ceramic substrate 61 quite uneven and even damaged', and if the ceramic substrate 61 has a semiconductor wafer or solder ball [solder bal 1] combined, it is easy to damage the package. The cutting method of the Tao Jing substrate is disclosed; f in the Japanese Patent Application Publication No. 7-4 0206 96 "the division method and division of the ceramic substrate" as shown in Figures 8a and 8b, It is to fix the substrate with separation gap 74 on both sides of the ceramic substrate 71 with the left fixture 72 and the right fixture 73, and use a hinge on the other side of the ceramic substrate 71 corresponding to the surface with the separation gap 74.

[Objective and summary of the invention] The main object of the present invention is to provide a method for fixing ceramic metopo by using an adhesive tape, and the ceramic substrate is divided along the separation seam, so that the ceramic ceramic substrate can be rectified and cleaned. Ground breaking: fast break the pottery effect. The second invention of this invention is to charge the ceramic substrate without knowing how to damage the ceramic substrate. The purpose is to deduct the manufacturing of a packaging structure that can be used every day. Page 6 V. Description of the invention (3) Process 'Among them, a plurality of flip-chip packaging structures use a ceramic substrate as a carrier, and use a tape to fix and fix one surface of a ceramic substrate with a wafer, and then bend the tape.' The ceramic substrate is broken along the separation gap to achieve a large number of rapid breaks. The effect of the ceramic substrate, cutting the ceramic substrate flatly and cleanly, and not damaging the flip-chip packaging structure. According to the method for breaking the ceramic substrate of the present invention, it at least includes: providing a ceramic substrate, It has a first surface, a second surface, and a plurality of separation seams; the first surface of the ceramic substrate is fixed with an adhesive tape; and the tape is bent to make the ceramic substrate break along the plurality of separation seams.

Explanation of the invention on page 7 (4) 1 4. In this embodiment, as shown in FIG. 2, the separation slits 14 are formed on the first surface 11 and the second surface 12 of the ceramic substrate 10, and each A wafer carrier 13 has a plurality of connecting pads 131 (connecting pads) formed on the second surface 12 of the ceramic substrate 10, and the connecting pads 131 are electrically connected to the corresponding connections on the first surface of the ceramic substrate and the first surface.塾 [not shown in the picture], it is used to receive solder ball 30 [solder ball]. Afterwards', as shown in FIG. 2, corresponding to the plurality of wafer carriers 3, there are a plurality of wafers 20 on the first surface 11 of the ceramic substrate 10 [flip_chip mounting], and a plurality of bumps 21 [bump ], Such as conductive solder such as gold, mechanically and electrically connect the first surface 11 of the ceramic substrate 10, and preferably each wafer 20 is sealed with an underfiH material 22 to protect the plurality of bumps 21 . -Next, as shown in FIG. 3, corresponding to the plurality of wafer carriers 13 on the second surface of the Z substrate 1 G! 2 Implanted with a plurality of solder balls 3 (), such as the solder of the wrong tin alloy, etc., to obtain a plurality of flip-chip packages I structure [fHp_chip ST The chip carrier 13 of each flip-chip package structure has not been cut off / integrated. The ground is formed on the ceramic substrate 10. To mention: the rear film H4 does not have a packaging structure with a first surface 41 and a second surface on the first surface 11 of the ceramic substrate 10, using the plurality of undivided ΑΜη々% l One surface 41 adheres and fixes the ceramic dual structure. “The glue is shown in the figure below” when the Taoman substrate 10 and the tape are 4 ° ii: = when at least-the driving wheel 50 is used to drive the lever 51, Bending the adhesive tape 40 'make the adhesive tape 40 five' Description of the invention (5) ^^ ----- -_- _ The side of the adhesive force = the adhesive Γ is pulled down and broken at the top, preferably, longitudinally first 4 f The ceramic substrate 10 is separated from the slit 14 along the separation slit 14 to make Tao Ziqi bend the tape 40, cut the longitudinal tape 40, cut the second tape into a strip shape, and then bend the knife horizontally for a second time. Break the slit 14 in the direction of 検, 佶: The 1n \ package is broken with + A ^ ^ θ to break the ceramic substrate 10 into individual breaks. Therefore, the separation slit 14 is used to break the Tao ridge flatly and completely. ί The ceramic substrate cutting method has a large amount of work to quickly study the substrate at a time. \ The knife-breaking ceramic is a complex of the substrate and the ceramic that does not damage the ceramic. It is shaped according to the cutting method of the ceramic substrate of the present invention. The crystal packaging structure is adhered to the tape, which is easy to store roses and transfer methods. The method of “5” of the ceramic substrate breaking method, “the bending tape 4” is a multi-knife. In the second embodiment, as shown in FIG. 6 The adhesive tape 40 does not move but moves the pressing rod 51, and the adhesive tape 40 makes the ceramic substrate 10 broken.
