[0048] Furthermore, the embodiments and features described herein can be combined with each other, unless otherwise specified.

[0049] refer to Figure 1 , Figure 1 This is a schematic diagram of a longitudinal cross-sectional structure of an embodiment of the cover according to the present disclosure.

[0050] like Figure 1 As shown, the upper cover 22 may include an upright portion 11.

[0051] The upright part 11 is a ring-shaped column and surrounds a receiving space 16. One end of the upright part 11 is provided with a first extension 12, and one end of the first extension 12 extends outward from the receiving space 16.

[0052] In this embodiment, the first extension 12, in conjunction with the outer wall of the upright portion 11, can be fitted with a waterproof rubber collar to achieve a waterproof effect. Furthermore, the first extension 12 can be formed by folding the tubular material forming the upright portion 11, simplifying the manufacturing process and reducing manufacturing costs.

[0053] In some alternative implementations, such as Figure 1 As shown, a second extension 13 is provided at one end of the first extension 12, and a turning part 15 is provided between the first extension 12 and the second extension 13.

[0054] The turning portion 15 includes a first turning angle 151 connecting the first extension portion 12, a third turning angle 153 connecting the second extension portion 13, and a second turning angle 152 disposed between the first turning angle 151 and the third turning angle 153. The first turning angle 151, the second turning angle 152 and the third turning angle 153 are arc-shaped.

[0055] In some alternative implementations, such as Figure 1 As shown, one end of the second extension 13 extends toward the axis 11a of the upright portion 11.

[0056] In some alternative implementations, such as Figure 1 As shown, the second extension 13 is provided with an opening 18, the width of which is smaller than the width of the accommodating space 16. Here, the width of the opening 18 is... Figure 1 The transverse cross-sectional diameter of the central opening 18 and the width of the accommodating space 16 are... Figure 1 The transverse cross-sectional diameter of the central accommodating space 16.

[0057] The opening 18, together with the accommodating space 16, forms a hole that can be used by the MEMS components located below the top cover 22 for sensing.

[0058] In some alternative implementations, such as Figure 1 As shown, the upper cover 22 also includes:

[0059] The base 14 is connected to the other end of the upright part 11, and one end of the base 14 extends outward from the accommodating space 16. The base 14 can be used to connect with the substrate when the upper cover 22 is set on the substrate.

[0060] In some alternative implementations, such as Figure 1 As shown, the axis 11a of the upright part 11 is perpendicular or approximately perpendicular to the plane where the first extension part 12 is located.

[0061] In some alternative implementations, such as Figure 1 As shown, the straight line containing the axis 11a of the upright portion 11 is perpendicular to the plane containing at least a portion of the upper surface of the second extension portion 13.

[0062] In some alternative embodiments, the cover 22 is made of metal to achieve electromagnetic interference shielding. The metal cover 22 can be adhered to the grounding requirement for electromagnetic shielding using an adhesive containing conductive material (e.g., metallic silver paste). Compared to plastic materials, the metal cover 22 provides a strong, rigid structure with a smaller thickness and reduces manufacturing costs.

[0063] In some alternative implementations, such as Figure 1 As shown, the side of the top cover 22 is provided with a groove 17.

[0064] It is understood that the groove 17 is composed of an upright portion 11, a first extension portion 12, and a base 14. The groove 17 is provided for a waterproof rubber collar to cooperate with the waterproof rubber sleeve to improve the waterproof sealing effect.

[0065] refer to Figure 2 , Figure 2 This is a longitudinal cross-sectional structural schematic diagram of one embodiment of the semiconductor packaging device according to the present invention.

[0066] like Figure 2 As shown, the semiconductor packaging device 200 may include:

[0067] The carrier 21 is provided with a receiving cavity 33.

[0068] The first electronic component 23 is disposed in the receiving cavity 33 and on the carrier 21.

[0069] The second electronic component 24 is stacked on top of the first electronic component 23.

[0070] Filler adhesive 34 covers the first electronic component 23 and the second electronic component 24.

[0071] The upper cover 22 is disposed on the carrier 21, corresponding to the receiving cavity. The upper cover 22 may include, for example, Figure 1 The specific structure of the upper cover 22 in any of the above embodiments is not described in detail here. Figure 2 For the specific structure of the unmarked upper cover 22, please refer to [the provided text]. Figure 1 As shown.

[0072] The first electronic component 23 may include an ASIC (Application Specific Integrated Circuit) chip.

[0073] The second electronic component 24 may include a MEMS component.

[0074] Here, the carrier 21 is not specifically limited, as long as the carrier 21 can provide the function of carrying the first electronic component 23 and the second electronic component 24.

[0075] In some alternative implementations, such as Figure 2 As shown, the carrier 21 may include a substrate 31 and a sidewall 32 disposed on the substrate 31, the sidewall 32 surrounding a receiving cavity 33.

[0076] The sidewall 32 can be a substrate, circuit layer, or redistribution layer disposed on the substrate 31, or other materials capable of providing support. Here, the sidewall 32 functions to enclose the receiving cavity 33, and the top cover 22 is disposed on the sidewall 32. In some alternative embodiments, the sidewall 32 can be made of a metallic material, or at least a portion of the surface of the sidewall 32 can be provided with a metallic material to further enhance the electromagnetic shielding effect in conjunction with the metallic top cover 22.

[0077] The filler 34 may include liquid and / or thin film organic materials, such as: non-conductive plastic (NCP), non-conductive film (NCF), anisotropic conductive adhesive film (ACF), anisotropic conductive adhesive plastic (ACP), polyimide (PI), epoxy resin, resin, PP (Prepreg, also known as prepreg or semi-cured resin, semi-cured sheet), ABF (Ajinomoto Build-up Film), glue, gel filling, etc.

[0078] The first electronic component 23 and the second electronic component 24 are protected by filler adhesive 34 to form a chemical and corrosion resistant protective layer, which can block dust particles and moisture, thus meeting the requirements for the use of sensing components in harsh environments.

[0079] In some alternative embodiments, the first electronic component 23 and the second electronic component 24 are stacked face up on the carrier 21. The first electronic component 23 is electrically connected to the second electronic component 24 via wire bonding, and the second electronic component 24 is electrically connected to the carrier 21 via wire bonding. The filler adhesive 34 covers the wire bonding area to provide protection for the wire bonding.

[0080] In some alternative implementations, such as Figure 2 As shown, the semiconductor packaging device 200 may further include: a waterproof rubber collar 26, which is fitted onto the side of the upper cover 22 corresponding to the groove 17 of the upper cover 22.

[0081] In some alternative embodiments, a sensor 25 is disposed on the second electronic component 24, with the sensor 25 at least partially exposed through the filler adhesive 34. The second electronic component 24 can sense the external environment through the sensor 25 through the opening 18 of the top cover 22 and the hole formed by the accommodating space 16.

[0082] Continue to refer to Figure 3 , Figure 3 This is a longitudinal cross-sectional structural schematic diagram of another embodiment of the semiconductor packaging device according to the present invention. Figure 3 The semiconductor packaging device 300 shown is similar to Figure 2 The semiconductor packaging device 200 shown is different in that the active surface of the second electronic element 24, on which the sensor 25 is disposed, is higher than the side wall 32. The end of the active surface of the second electronic element 24 is disposed in the accommodating space 16 of the upper cover 22. The surface of the second electronic element 24 is covered with a protective layer 35, and the surface on which the sensor 25 is disposed is exposed through the protective layer 35.

[0083] The protective layer 35 can be formed from various molding compounds. For example, molding compounds may include epoxy resin, filler, catalyst, pigment, release agent, flame retardant, coupling agent, hardener, low stress absorber, adhesion promoter, ion trapping agent, etc.

[0084] In this embodiment, the height of the second electronic component 24 exceeds the receiving cavity 33, and the filler adhesive 34 may not be able to adequately protect the second electronic component 24. By providing a protective layer 35, the waterproof effect of the part of the second electronic component 24 not covered by the filler adhesive 34 can be improved.

[0085] Figure 4 This is a schematic diagram of a semiconductor packaging manufacturing method flow 400 according to an embodiment of the present disclosure, as shown below. Figure 4 As shown, the manufacturing process 400 of a semiconductor packaging device may include the following steps:

[0090] Here, curing can be achieved by heating the adhesive.

[0091] Step 404: Attach the first electronic component 23.

[0092] Here, the non-active surface of the first electronic component 23 can be bonded to the substrate 31 using an adhesive.

[0093] The first electronic component 23 can be transmitted via, for example, Figure 4 Steps 501 to 504 shown herein yield the following results:

[0094] Step 501: Provide a wafer of the first electronic component 23.

[0095] Step 502: Grinding the wafer of the first electronic component 23.

[0096] It is understandable that, in order to correspond to the size of the semiconductor packaging device 300, the wafer can be ground to reduce the wafer thickness, thereby reducing the space occupied by the first electronic component 23 in the vertical direction.

[0097] Step 503: Install the wafer of the first electronic component 23.

[0098] Step 504: Mechanically cut the wafer of the first electronic component 23 to obtain the first electronic component 23.

[0105] Step 601, providing a wafer of the second electronic component 24.

[0106] Step 602: Grinding the wafer of the second electronic component 24.

[0107] It is understandable that, to accommodate the size of the semiconductor packaging device 300, the wafer can be ground to reduce the wafer thickness, thereby reducing the vertical space occupied by the second electronic component 24. Here, step 602 is an optional step, and can be performed according to the actual packaging size requirements.

[0108] Step 603: Install the wafer of the second electronic component 24.

[0112] Here, curing can be achieved by heating the adhesive.

[0113] Step 408, Plasma clean.

[0114] Step 409, connect the wires.

[0115] Here, the substrate 31 and the first electronic component 23, as well as the first electronic component 23 and the second electronic component 24, can be connected by wire bonding.

[0116] Step 410, Visual inspection.

[0117] Step 411, gel filling.

[0118] Here, the gel covers at least a portion of the first electronic component 23 and the second electronic component 24.

[0119] Step 412, gel solidification.

[0120] Here, the gel can be cured by heating to form filler 34.

[0121] Step 413: Wire bonding coating of the second electronic component 24.

[0122] In some embodiments, the portion of the wires connecting the second electronic component 24 is not fully covered in step 411. Therefore, the wires connected to the second electronic component 24 are coated here by coating the wires with a gel material.

[0123] Step 414: Curing of the coating material.

[0124] Here, the coating material can be cured by heating to form a shape such as Figure 3 The filler adhesive 34 structure is shown.

[0125] Step 415, connect the top cover 22.

[0126] Here, the top cover 22 can be glued to the side wall 32 using an adhesive.

[0127] Step 416, top cover 22 connection and curing.

[0128] Here, curing can be achieved by heating the adhesive.

[0129] Step 417, laser marking.
