[0017] As shown in Fig. 1, in an oscillator 10 of the related art, a single cavity is formed using a ceramic base 13, and a resonator 11 and an oscillation chip 12 are mounted on different layers. In general, the resonator 11 can be a quartz crystal resonator having piezoelectric properties, and is connected to the ceramic base 13 using a conductive medium such as conductive silver paste 15. In addition, since the oscillation chip 12 and the quartz crystal resonator 11 are electrically connected via the ceramic base 13, the pins of the oscillation chip 12 can be measured through the electrode structure 14 (e.g., solder pad) at the bottom of the ceramic base 13, and the progress of the frequency fine-tuning process can be ensured.
[0018] 2, in an oscillator 20 of another related art, a ceramic base 23 can form an H-shaped upper and lower double cavity for respectively mounting an oscillation chip 22 and a resonator 21. The advantage of the H-shape is that the arrangement spaces of the oscillation chip 22 and the resonator 21 are independent under a compact and tense space.
[0019] As shown in Figures 1 and 2, no matter how much it is compressed, the carrier substrate such as the ceramic substrate 13, 23 must have at least a boss for mounting the oscillator 11, 21, and the pins of the oscillator chip 12, 22 must be connected through the electrode structure 14 at the bottom of the ceramic substrate 13, 23. However, the inventors have found that there are some drawbacks when adopting the above-mentioned packaging method of Figures 1 and 2. Specifically, there is a certain limit to the miniaturization of the oscillator chip 12, 22, and the cavity space must be so large, and the wall thickness of the ceramic substrate 13, 23 can only be extruded more and more narrow, and the electrode structure 14, 24 is also relatively narrow. Even the most advanced products of some international head manufacturers have a technical bottleneck that the oscillator cannot be miniaturized.
[0020] According to the above-mentioned packaging method, it is difficult to miniaturize the oscillator chips 12, 22, which makes it difficult to miniaturize the cavities of the ceramic bases 13, 23, which leads to a stagnation in the progress of miniaturization of the entire oscillators 10, 20. In addition, in other related technologies, there is a technical problem that it is difficult to realize a miniaturized package for silicon-based oscillators as well.
[0021] In view of this, the present application further proposes an oscillator structure and its manufacturing method, which can achieve a miniaturized package and obtain an oscillator of smaller size.
[0022] Hereinafter, an oscillator provided according to an embodiment of the present invention and a method for manufacturing the same will be described in further detail with reference to FIGS.
[0023] <Example 1> As shown in Fig. 3 to Fig. 5, Fig. 3 is a schematic diagram of a cross-sectional structure of an oscillator 30 provided by Example 1 of the present application. Fig. 4 is a schematic top view of the oscillator 30 provided by Example 1 of the present application. Fig. 5 is a schematic bottom view of the oscillator 30 provided by Example 1 of the present application. The oscillator 30 includes a resonator 31, an oscillation chip 32, an insulating layer 33, and a first electrode structure 34.
[0024] The vibrator 31 includes a vibrating element 311 and an airtight sealing structure 312 sealed around the outer periphery of the vibrating element 311. The vibrator 31 is an already packaged vibrator element. In this embodiment, the vibrator 31 will be mainly described as a ceramic packaged crystal vibrator.
[0025] The oscillator chip 32 may be provided on one side of the hermetic sealing structure 312 and electrically connected to the hermetic sealing structure 312 .
[0026] The insulating layer 33 covers at least one side of the oscillation chip 32 and the airtight sealing structure 312, and has a first conductive hole 331. The first conductive hole 331 contains a conductive material. The first electrode structure 34 is provided on the insulating layer 33, and is electrically connected to the oscillation chip 32 through the conductive material in the first conductive hole 331. The first electrode structure 34 may be a pad structure such as a solder pad. The insulating layer 33 is a resin material. The first electrode structure 34 includes a plurality of first electrodes (i.e., a plurality of pads). The number of the first conductive holes 331 corresponds to the number of the first electrodes. This allows the first electrodes to be electrically connected to the conductive material in the corresponding first conductive hole 331. As shown in FIG. 3, in this embodiment, the number of first electrodes of the first electrode structure 34 is four, and they are provided at the four corners of the bottom of the oscillator 30, respectively.
[0027] In the oscillator 30 provided by the embodiment of the present application, the oscillation chip 32 is directly installed on one side of the hermetically sealed structure 312 of the already packaged oscillator 31, and furthermore, the oscillator 31 and the oscillation chip 32 are sealed via the insulating layer 33, and there is no need to install a carrier base and its cavity for packaging the oscillator 31 and the oscillation chip 32, and the problem that it is difficult to miniaturize the oscillator 30 due to the carrier base and its cavity can be avoided, and the packaging of a miniaturized oscillator can be realized. In addition, since the insulating layer 33 is covered by the oscillation chip 32, the oscillation chip 32 is not exposed, and the oscillation chip 32 can be better protected. In addition, the first electrode structure 34 is provided on the insulating layer 33, and can respond to stress generated from the client terminal side on which the oscillator 30 is placed on the circuit board, and has a role of buffering. This improves the reliability of the oscillator 30 and the circuit board having the oscillator 30.
[0028] Specifically, the hermetic sealing structure 312 includes a ceramic base 3121 having a cavity 3121a, a cover plate 3122 covered by the ceramic base 3121, and a second electrode structure 3123 provided on the ceramic base 3121. A conductor structure 3121b may be provided in the ceramic base 3121. The vibration element 311 may be provided in the cavity 3121a and electrically connected to the conductor structure 3121b via a conductive adhesive 3121c (e.g., a conductive adhesive). The second electrode structure 3123 is further electrically connected to the conductor structure 3121b and is also electrically connected to the oscillation chip 32 so that the oscillation chip 32 is electrically connected to the vibrator 31. The second electrode structure 3123 may be a welding pad structure and may include a plurality of second electrodes (i.e., a plurality of pads). The number of the conductor structures 3121b may correspond to the number of the second electrodes. This allows the second electrode to be electrically connected to the corresponding conductor structure 3121b. The vibration element 311 is made of a quartz crystal material.
[0029] Furthermore, in this embodiment, the insulating layer 33 further includes a second conductive hole 335. The second conductive hole 335 includes a conductive material. The second electrode structure 3123 is electrically connected to the oscillation chip 32 through the conductive material in the second conductive hole 335.
[0030] In this embodiment, the insulating layer 33 may be deposited on one side of the oscillation chip 32 and the hermetic sealing structure 312 by a first semiconductor deposition process. The first conductive hole 331 may be formed in the insulating layer 33 by a semiconductor etching process. A conductive material is formed in the first conductive hole 331 by a second semiconductor deposition process. The first electrode structure 34 is formed in the insulating layer 33 by a third semiconductor deposition process. The semiconductor etching process can realize the patterning of the material layer to be etched by sequentially depositing the material to be etched and a photosensitive etchant, and exposing them together with a patterned mask.
[0031] <Example 2> Fig. 6 is a cross-sectional view of an oscillator 40 provided by Example 2 of the present application. As shown in Fig. 6, the oscillator 40 in Example 2 is basically the same as the oscillator 30 in Example 1. That is, the above description of the oscillator 30 in Example 1 is basically applicable to the oscillator 40 in Example 2. The following mainly describes the differences between the oscillator 40 in Example 2 and the oscillator 30 in Example 1.
[0032] In the oscillator 40 of the second embodiment, the first seal member 4124, the second seal member 4125, and the vibration element 411 are all made of quartz crystal material. That is, the vibrator 41 is a fully quartz crystal packaged vibrator. The package structure 412 includes a first seal member 4124 provided on one side of the vibration element 411, a second seal member 4125 provided on the other side of the vibration element 411, and a second electrode structure 4123 provided on the first seal member 4124.

[0033] Specifically, in this embodiment, the oscillation chip 42 is provided on the first sealing member 4124 and is electrically connected to the second electrode structure 4123. The insulating layer 33 covers the oscillation chip 42 and the first sealing member 4124. Basically the same as in the first embodiment, the oscillation chip 42 is directly installed on one side of the package structure 412 of the already packaged oscillator 41, and furthermore, the insulating layer 43 realizes the sealing protection of the oscillator 41 and the oscillation chip 42, and there is no need to install a carrier base and a cavity for packaging the oscillator 41 and the oscillation chip 42, and the problem that the size of the oscillator 40 is difficult to reduce due to the carrier base and the cavity can be avoided, and the packaging of the miniaturized oscillator can be realized. In addition, since the insulating layer 43 is covered on the oscillation chip 42, the oscillation chip 42 is not exposed, and the oscillation chip 42 can be better protected. In addition, the first electrode structure 44 is provided on the insulating layer 43, and can withstand stress generated from the client terminal side on which the oscillator 40 is arranged on the circuit board, and has a buffering role, thereby improving the reliability of the oscillator 40 and the circuit board having the oscillator 40.
[0034] <Example 3> Fig. 7 is a cross-sectional view of an oscillator 50 provided by Example 3 of the present application. As shown in Fig. 7, the oscillator 50 in Example 3 is basically the same as the oscillator 30 in Example 1. That is, the above description of the oscillator 30 in Example 1 can also be basically applied to the oscillator 50 in Example 3. The following mainly describes the differences between the oscillator 50 in Example 3 and the oscillator 30 in Example 1.
[0035] In the oscillator 50 of the third embodiment, the vibrator 51 is a silicon-based vibrator sealed entirely with silicon. The position of the insulating layer 53 is different from that of the first and second embodiments. Specifically, in the vibrator 51, the airtight sealing structure 512 includes a first seal member 5124 provided on one side of the vibrating element 511, a second seal member 5125 provided on the other side of the vibrating element 511, and a second electrode structure 5123 provided on the first seal member 5124. The first seal member 5124, the vibrating element 511, and the second seal member 5125 all include silicon material. The second electrode structure 5123 is electrically connected to the oscillation chip 52. The second electrode structure 5123 is further electrically connected to the oscillation chip 52 via the conductive material in the second conductive hole 535.
[0036] The vibrator 51 is provided on a first surface of the oscillation chip 52. The insulating layer 53 covers the vibrator 51, the first surface 521 of the oscillation chip 52, the second surface 522 facing the opposite side to the first surface 521 of the oscillation chip 52, and the side surface 523 connected between the first surface 521 and the second surface 522. Specifically, the insulating layer 53 has a base portion 530 and a covering portion 532. The first surface of the oscillation chip 52 is disposed on the base portion 530. The covering portion 532 is provided on the second surface 522 facing the opposite side to the first surface 521 of the oscillation chip 52, the side surface 523 connected between the first surface 521 and the second surface 522, and the vibrator 11. Here, the base portion 530 and the covering portion 532 may be formed sequentially by different semiconductor deposition processes.
[0037] In the oscillator 50 of the third embodiment, the insulating layer 53 covers and protects both the resonator 51 and the oscillation chip 52, which not only avoids the problem of the carrier substrate and its cavity making it difficult to reduce the size of the oscillator 50, but also responds to the stress generated in the client terminal in which the oscillator 50 is placed on the circuit board, and plays a buffering role. This further improves the reliability of the oscillator 50 and the circuit board having the oscillator 50. In addition, the resonator 51 is a silicon-based resonator that is fully sealed with silicon, and its size is smaller, so that the size of the finally obtained oscillator 50 is also smaller. In addition, the structural position design of the insulating layer 53 also improves the airtightness of the oscillator 50.
