- Terminal electrodes 15a and 15b are provided on the first main surface 13a.

- FIG. 1B on the first main surface 13a of the first piezoelectric substrate 13, six first Au bumps 16a to 16f are arranged. That is, the first acoustic wave element 11 is mounted on the package substrate 2 using the first Au bumps 16a to 16f in a face-down manner.

- the sealing resin layer 5 does not reach the area surrounded by the plurality of first Au bumps 16a to 16f and the area surrounded by the plurality of second Au bumps 26a to 26f. This is to form the hollow spaces A and B.
- the feature of the acoustic wave device 1 is that the first Au bumps 16a to 16f as the first metal bumps are larger than the second Au bumps 26a to 26f as the second metal bumps. That is, in the relatively large first elastic wave element 11, the first Au bumps 16a to 16f used are the second metal bumps used in the relatively small second elastic wave element 12. Larger than the second Au bumps 26a to 26f. As a result, even if a thermal shock is applied during reflow, heat shock testing, or actual use, the first Au bumps 16a to 16f and the second Au bumps 26a to 26f are unlikely to peel off due to thermal stress. This will be described with reference to FIGS.
- the size of the first Au bumps 16a to 16f and the second Au bumps 26a to 26f is the same as that of the first Au bumps 16a to 16f when seen in plan view and the second Au bumps 26a to 26f. It is determined by the plane area of the Au bumps 26a to 26f. Therefore, the size of the Au bumps may be determined by the size of the diameters of the Au bumps 16a to 16f and 26a to 26f proportional to the plane area.
- the inventors of the present application have used the relatively large first Au bumps 16a to 16f on the first elastic wave element 11 side having a relatively large size. For example, it has been found that the peeling of the first Au bumps 16a to 16f can be effectively suppressed.
- FIG. 2 is a diagram showing the relationship between the diameter of the Au bump, the number of cycles in the heat shock (HS) test, and the failure rate Ft (%).
- HS heat shock
- Ft failure rate
- the failure rate increases as the number of heat shock test cycles increases. It can be seen that the heat shock resistance increases as the diameter of the Au bump increases from 100 ⁇ m to 120 ⁇ m and 150 ⁇ m.
- the failure rate Ft (%) is the ratio of the acoustic wave device in which the filter characteristics are reduced after the heat shock test and the filter characteristics are worse than before the test.
- the first and second acoustic wave elements 11 and 12 were mounted on the package substrate 2 at a temperature of 250 ° C. according to the flip chip bonding method. Thereafter, the maximum principal stress on the upper surface of the Au bump on the second acoustic wave element 12 side when cooled to ⁇ 40 ° C. and maintained for 30 minutes was measured by a stress analysis simulation. In this case, the following Experimental Examples 1 to 4 were performed.
- Experimental example 2 Size of second elastic wave element 12: large. Specifically, the second piezoelectric substrate 23 having a size of 0.85 mm ⁇ 1.32 mm ⁇ 0.2 mm was used. The size of the second Au bumps 26a to 26f: large. Specifically, the diameters of the second Au bumps 26a to 26f were 150 ⁇ m.
- Experimental example 4 Size of second elastic wave element 12: small. Specifically, the second piezoelectric substrate 23 having a size of 0.81 mm ⁇ 1.11 mm ⁇ 0.2 mm was used. The size of the second Au bumps 26a to 26f: large. Specifically, the diameters of the second Au bumps 26a to 26f were 150 ⁇ m.
- FIG. 4 is a schematic plan view showing the positional relationship between the second Au bumps 26a to 26f joining the second acoustic wave element 12 in Experimental Example 1 and the electrode land.
- FIG. 3 is a diagram showing the relationship between the element size and bump size of the acoustic wave elements of Experimental Examples 1 to 4 and the maximum principal stress on the bump upper surface at ⁇ 40 ° C. after mounting.
- the vertical axis represents the maximum principal stress on the upper surface of the second Au bump 26e.
- the maximum principal stress applied to the second Au bump 26e varies greatly depending on the size of the plane area of the second acoustic wave element 12 and the size of the second Au bump 26e. Recognize. In FIG. 3, only the maximum principal stress on the second Au bump 26e is shown, but it has been confirmed that the same tendency exists in the other second Au bumps 26a to 26d and 26f.
- the first Au bumps 16a to 16f on the first acoustic wave element 11 side to which a larger thermal stress is applied are made larger than the second Au bumps 26a to 26f. This makes it difficult for the first Au bumps 16a to 16f and the second Au bumps 26a to 26f to peel off when heat shock is applied.
- the second Au bumps 26a to 26f are relatively small. Therefore, downsizing can be promoted.
- FIG. 5 (a) shows the initial state, which is under a temperature of about 25 ° C.
- the Au bump 101 joins the terminal electrode 102 of the acoustic wave element 104 and the electrode land 103 on the package substrate 106.
- the temperature is first maintained at 125 ° C. for 30 minutes.
- the upper portion of the Au bump 101 is the X direction that is the outer direction of the package. Try to move to.
- the thermal stress can be reduced by providing relatively large first Au bumps 16a to 16f on the side of the first acoustic wave element 11 having a large plane area. Therefore, the first Au bumps 16a to 16f are hardly peeled off. In addition, the second Au bumps 26a to 26f are not easily subjected to a large thermal stress, and thus are unlikely to peel off.
- the second sealing by the sealing resin layer 5 in the second acoustic wave element 12 described below is performed. It is desirable to make the width W2 larger than the first sealing width W1 by the sealing resin layer 5 of the first acoustic wave element 11.
- the first and second sealing widths W1 and W2 are the side surfaces 13c to 13f and 23c to 23c of the first and second piezoelectric substrates 13 and 23 of the first and second acoustic wave elements 11 and 12, respectively.
- the sealing width W1 in the first acoustic wave element 11 is shown in FIGS. 1 (a) and 1 (b).
- the second sealing width W2 of the second acoustic wave element 12 is also shown in FIGS. 1 (a) and 1 (b). That is, the first sealing width W1 is defined between the side surface 13d of the first piezoelectric substrate 13 closest to the first Au bump 16a and the outer side surface 5a of the sealing resin layer 5 facing the side surface 13d. Is the distance between.
- the second sealing width W2 is between the side surface 23f of the second piezoelectric substrate 23 closest to the second Au bump 26b and the outer surface 5b of the sealing resin layer 5 facing the side surface 23f. Is the distance.
- FIG. 6 is a diagram showing the relationship between the sealing width and the maximum principal stress applied to the upper surface of the Au bump.
- This maximum principal stress is a stress applied to the upper surface of the second Au bump after being maintained at ⁇ 40 ° C. for 30 minutes after mounting the package substrate.
- the monitor in FIG. 6 is a sealing resin layer having a size of 2.1 mm ⁇ 1.6 mm ⁇ 0.4 mm, the size of the second acoustic wave element 12 is a planar shape of 0.75 mm ⁇ 1.32 mm, the first This is the result when the planar shape of the elastic wave element 11 is 0.85 mm ⁇ 1.32 mm and the sealing width of the second elastic wave element 12 is 150 ⁇ m. As is apparent from FIG.
- the thermal stress increases when the sealing width is narrowed by 50 ⁇ m or 100 ⁇ m than the sealing width of the monitor. Therefore, it is desirable to increase the second sealing width on the relatively small second acoustic wave element 12 side, where the influence of the sealing width is relatively large. Therefore, it is preferable that the second sealing width W2 is wider than the first sealing width W1 on the second acoustic wave element 12 side where the change in thermal stress greatly affects.
- the sealing width means the outer surface of the sealing resin layer covering the first and second acoustic wave elements themselves and the first and second acoustic wave elements. It is defined by the distance between the side surfaces of the second piezoelectric substrate. Therefore, for example, in the module component 31 as in the modification shown in FIG. 7, the resin layer 34 located on the outermost side of the module component 31 may not be considered. In the module component 31 shown in FIG. 7, not only the acoustic wave device 1 of the above embodiment but also other electronic components 33 are mounted on the module substrate 32. The elastic wave device 1 and the electronic component 33 are covered with a resin layer 34. The resin layer 34 does not correspond to a sealing resin layer that directly covers the first and second acoustic wave elements 11 and 12. Also in the module component 31, the sealing width may be defined on the basis of the outermost surface of the sealing resin layer 5.
- the first and second Au bumps 16a to 16f and 26a to 26f are used as the first and second metal bumps.
- solder bumps may be used.
- the HS test was performed when the bump diameter was 80 ⁇ m and when the bump diameter was 100 ⁇ m. That is, the number of times of failure was measured by setting the above-mentioned step of maintaining at ⁇ 40 ° C. for 30 minutes and the step of maintaining at 125 ° C. for 30 minutes as one cycle. The results are shown in Table 1 below.

- a semiconductor element that is electrically connected to at least one of the first and second acoustic wave elements may be provided.
- the semiconductor element may be mounted on the package substrate.
- the material for the substrate of the acoustic wave device or the semiconductor device is not particularly limited.
- a piezoelectric single crystal such as LiTaO 3 or LiNbO 3 or a piezoelectric material such as piezoelectric ceramics, or a semiconductor such as Si or GaAs can be given.
