Description of the Invention: The present invention relates to a wafer interlaminar strength testing device, and more particularly to a testing device capable of accurately measuring the interlaminar strength between wafers. [Prior Art] With the miniaturization of the wafer process, the advancement of integrated circuit technology has become more and more extensive, and the level of wafer application has become wider and wider. Therefore, packaging the wafer to bury the plastic material is a step in the manufacturing process of the semiconductor device. In the process, the material itself and the interface between the materials need to be subjected to a number of heat treatment steps. Although the heat treatment process is not a direct pin-to-pair, the film itself, because of this, it is necessary to perform the precision measurement of the inter-layer strength of the wafer during the heat treatment. (4) The structure between the layers of the wafer is strong: it will indirectly cause the crystal (4) to be installed in the circuit, and the defects occur: many heat treatment procedures, such as the steps of the adhesive crystal, reflow and sealant, are necessary. Modulus or thermal expansion % pole: can cause stress between material and material, material and glue (especially in the dielectric layer or protective layer of the wafer, ancient, low yield and poor package reliability) Wait for the result. Therefore, it is necessary to perform the ground detection of the wafer phase intensity. Brother 1 is the conventional wafer strength test. No. 200520127, “耔#士1r毕民国公专利.

Thereby, the moment between the layers of the wafer 81, or the interface between the wafer and the potting molded product 82 is destroyed, that is, the inter-layer stress of the wafer 81 is measured or the shear stress of the glue is formed. size.曰

In the hall, another test, the wafer strength test device, is described in the Republic of China, No. 428263, "Testing Lead_〇n_Chip (L〇c) Wafers and Lead Frames." It is a fixture-clamp: the force is applied to the side of one of the wafers of the wire holder, and the far-acting force of the straight dragon wafer is continuously damaged, or it is separated from the wire holder. The bonding strength of the package structure to be tested is known. . In general, the above-mentioned practices have many disadvantages, such as measuring the seal, the σ s strength or the inaccurate adhesion, the vertical component in the detection process, and even the bending deformation of the detection platform. For the above reasons, the inter-wafer strength test of the wafer disclosed in the embodiment of the present invention can be accurately measured for the strength of the wafer package factory.

Referring to FIG. 2, the inter-wafer strength testing device of the embodiment includes a detecting platform 1, a first coating platform 2 and a second coating platform 3. The detecting platform 1 has a first surface η and a second surface 12, and the first surface 11 and the second surface 12 are parallel to each other, so that the two wafers to be tested 4 are respectively attached to the first surface 11 and The first coating platform 2 and the second coating platform 3 are respectively adjacent to the first surface 11 and the second surface 12 of the detecting platform 1, and the two coating platforms 2, 3 each have a surface parallel The first and second surfaces 11, 12 are disposed so that the two coating platforms 2, 3 are attached to the wafer 4 to be tested disposed on the two surfaces 11, 12. The two wafers to be tested 4 can be selected as a semiconductor material, for example, the same chip. In addition, a glue material 5 is disposed between each of the test wafers 4 and the surface of the detection platform 1, the first coating platform 2, and the second coating platform 3, and the glue is preferably selected as a liquid.

Therefore, when the detecting platform worker applies the damage external force to the coffin j, the stability can be further enhanced, so that the coating platform ^f, the coating table 3 and the detection platform i are stable and stable. Increase the measurement accuracy of the damage external force. Sincerely, the detection platform! Alternatively, the fixing hole 13 may be provided for a tensioning device (not shown) to provide a stable external force of the detecting platform 1. By dividing the measured external force of the damage by the coated area of the glue 5 on the wafer 4 to be tested, it is obtained that the shearing force of the wafer 4 to be tested is damaged. In general, with respect to the surface area of the test wafer 4, the coated area of the adhesive material 5 is preferably equal to the surface area of the wafer 4 to be tested, thereby further increasing the test accuracy of the shearing mechanical strength. It should be known to those skilled in the art that the design methods of the testing platform 1 and the first and second coating platforms 2 and 3 are different, and the adhesive 5 can be used according to various semiconductor processes. The choice, the curing, and the parts are therefore different, so the application of the invention should not be limited thereto. For example, the first coating platform 2 may not be provided with the fixing hole 21, and the first coating platform 3 may not be provided with the fixing hole 31, but directly integrated into the i-shaped and _ stable structure. For example, the chassis of the test machine is more than 疋. Similarly, the detecting platform 1 may not be provided with the fixing hole 13 but directly combined with the tensioning device. Of course, the tension device can be connected to a recorder (not shown, such as a personal computer and analysis software), PK10324 2007/6/7 10 - 200848730 in order to record the plating damage required for previous tests. In other words, the spirit of the present invention is that the detection platform 1 can simultaneously apply the two wafers to be tested 4 as long as the two coating platforms 2 仏 3 ^ ^ are placed on the symmetrical sides of the detection platform 1 . The same amount of damage is applied to minimize the positive component of the two phases 2 generated between the layers of the two wafers to be tested 4 or between the layers to more accurately measure the external force that is destroyed. Thanks to the detection platform of the invention! The first coating platform 2 and the second coating platform 3 are each formed by using only a plurality of simple planes, and the coffin 5 is manually or mechanically applied directly to the plane.

Therefore, for wafer packaging and wafer production, the finished product is processed and the related inspection of the wafer is performed. (4) The gate L j needs to meet its requirements, and can be directed to the strength of each layer of the wafer 4 = between: or the layers of the wafer 4 itself, or After the heat curing of the rubber material 5, the bonding strength between the crystals 4 is accurately measured.

Therefore, after the liquid or solid glue 10524 2007/6/7 200848730 is bonded and fixed to the wafer to be tested, the detecting platform can apply a same magnitude of destructive force to the interlayer structure of the two wafers to be tested, and can cause damage to the external force. The positive component force is minimized to measure and record the strength between the layers of the two crystal cells to be measured. If the interlayer structure of the crystal is good, when the glue is damaged, the wafer to be tested is not damaged, then the record is recorded.
