Description

Technical Field

[0001] The present invention generally relates to semiconductor device packages and methods of manufacturing the same, and more particularly to semiconductor device packages including conductive pillar structures and methods of manufacturing the same. Background Art

[0002] In some existing processes for forming connection structures (e.g., fan-out structures) for semiconductor device packages, a circuit layer is placed on a carrier with fine-pitch conductive traces (e.g., line spacing (L / S) equal to or less than 7 micrometers (μm) / 7 μm) on one side of the circuit layer (e.g., the chip side), and then coarse-pitch conductive traces are formed on the other side of the circuit layer (e.g., the ball side). However, due to misalignment (x- and y-directions) and horizontal errors (z-direction), the conductive traces will not be accurately formed on the circuit layer, which will cause electrical problems (e.g., short circuits or open circuits).

[0003] In other existing processes for forming connection structures, coarse-pitch conductive traces can be formed on the ball side of the circuit layer, and then fine-pitch conductive traces are formed on the chip side of the circuit layer.

[0018] Figure 1A A cross-sectional view of a semiconductor device package 1 according to some embodiments of the present invention is illustrated. The semiconductor device package 1 includes dielectric layers 10 and 11, an electronic component 12, a package body 13, and electrical contacts 14.

[0019] The dielectric layer 10 has a surface 101 (also referred to as a "top surface"), a surface 102 opposite to the surface 101 (also referred to as a "bottom surface"), and a surface 103 extending between the surfaces 101 and 102 (also referred to as a "lateral surface"). One or more conductive layers 10r1 are disposed on the surface 101 of the dielectric layer 10. One or more conductive layers 10r2 are disposed on the surface 102 of the dielectric layer 10. In some embodiments, conductive vias 10v penetrate the dielectric layer 10 to provide electrical connections between the surfaces 101 and 102 of the dielectric layer 10. For example, the conductive vias 10v can electrically connect the conductive layers 10r1 to the conductive layers 10r2. In some embodiments, the conductive vias 10v taper from the surface 101 toward the surface 102 (or in a direction away from the electronic component 12). In some embodiments, conductive layer 10r1 includes a plurality of conductive traces, and the line spacing (L / S) of the conductive traces is equal to or less than 2 micrometers (μm) / 2 μm. In some embodiments, conductive layer 10r2 includes a plurality of conductive traces, and the L / S of the conductive traces is equal to or greater than 5 μm / 5 μm. In some embodiments, the thickness of dielectric layer 10 ranges from approximately 5 μm to approximately 10 μm. In some embodiments, dielectric layer 10, conductive layer 10r1, and conductive vias 10v may be collectively referred to as a circuit layer.

[0020] Dielectric layer 11 covers surface 102 of dielectric layer 10 and portions of surface 103 of dielectric layer 10. For example, dielectric layer 11 may cover a first portion of surface 103 of dielectric layer 10 and expose a second portion of surface 103 of dielectric layer 10. For example, surface 111 of dielectric layer 11 (also referred to as the "top surface") is not coplanar with surface 101 of dielectric layer 10. For example, surface 111 of dielectric layer 11 and surface 101 of dielectric layer 10 are discontinuous. One or more conductive layers 11r are disposed on surface 112 (also referred to as the "bottom surface") of dielectric layer 11. In some embodiments, conductive vias 11v penetrate dielectric layer 11 to electrically connect conductive layer 11r to conductive layer 10r2. In some embodiments, conductive vias 11v taper from surface 112 toward surface 111 (or in the direction of electronic component 12). In some embodiments, dielectric layer 11 has a thickness ranging from approximately 10 μm to approximately 30 μm. In some embodiments, the dielectric layer 11, the conductive layer 11r, and the conductive vias 11v may be collectively referred to as circuit layers. In some embodiments, the semiconductor device package 1 may include any number of circuit layers. For example, the semiconductor device package 1 may include N circuit layers, where N is an integer greater than 1.

[0021] In some embodiments, conductive layer 10r1, 10r2, or 11r is formed of or includes gold (Au), silver (Ag), copper (Cu), platinum (Pt), palladium (Pd), other metals or alloys, or a combination of two or more thereof. In some embodiments, dielectric layer 10 or dielectric layer 11 may include molding compound, pre-impregnated composite fiber (e.g., prepreg), borophosphosilicate glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, undoped silicate glass (USG), glass, ceramic, any combination of two or more thereof, or the like. Examples of molding compound include, but are not limited to, epoxy resin (including fillers dispersed therein). Examples of prepreg material include, but are not limited to, a multilayer structure formed by stacking or laminating multiple prepreg materials / sheets. In some embodiments, dielectric layer 10 and dielectric layer 11 include the same material. Alternatively, dielectric layer 10 and dielectric layer 11 may comprise different materials. In some embodiments, dielectric layer 10 comprises a photosensitive material. In some embodiments, conductive layer 10r1 may be formed by photolithography.

[0022] Electronic component 12 is disposed on surface 101 of dielectric layer 10 and is electrically connected to a conductive layer (or conductive pad) 10r1 on surface 101 of dielectric layer 10 via conductive contacts 12c (e.g., microbumps). In some embodiments, a chip backside layer (not shown) may be disposed on backside surface 122. In some embodiments, the chip backside layer may comprise Cu, Ni, Ti, W, or Pt, other metals or alloys, or a combination of two or more thereof. In other embodiments, the chip backside layer may comprise PI, ABF, epoxy, CPD, or solder mask. Electronic component 12 may comprise a chip or die, including a semiconductor substrate, one or more integrated circuit devices, and / or one or more overlying interconnect structures disposed therein. The integrated circuit devices may comprise active devices such as transistors and / or passive devices such as resistors, capacitors, inductors, or a combination of two or more thereof. In some embodiments, any number of electronic components may be disposed on surface 101 of dielectric layer 10, depending on the design specifications.

[0023] The package body 13 is disposed on the dielectric layer 10 and the dielectric layer 11. The package body 13 covers the surface 101, the portion (e.g., the second portion) of the surface 103 of the dielectric layer 10 exposed from the dielectric layer 11, the surface 111 of the dielectric layer 11, and the electronic component 12. For example, the interface between the package body 13 and the dielectric layer 11 is located on or adjacent to the surface 103 of the dielectric layer 10, which will avoid cracking or delamination at the interface. In some embodiments, the surface 131 of the package body 13 is substantially coplanar with the backside surface 122 of the electronic component 12. For example, the backside surface 122 of the electronic component 12 is exposed from the package body 13. Alternatively, the package body 13 may cover the backside surface 122 of the electronic component 12. In some embodiments, the surface 133 of the package body 13 is substantially coplanar with the surface 113 of the dielectric layer 11. In some embodiments, package body 13 includes, for example, an organic material (e.g., molding compound, bismaleimide triazine (BT), PI, polybenzoxazole (PBO), solder resist, ABF, polypropylene (PP), epoxy-based materials, or a combination of two or more thereof), an inorganic material (e.g., silicon, glass, ceramic, quartz, or a combination of two or more thereof), a liquid film material, or a dry film material, or a combination of two or more thereof. In some embodiments, package body 13 may be a coating gel. In some embodiments, solder layer 13 has a thickness ranging from approximately 100 μm to approximately 350 μm.

[0024] Electrical contacts 14 are disposed on surface 112 of dielectric layer 11 and electrically connected to conductive layer 11r or conductive vias 11v. In some embodiments, electrical contacts 14 are controlled collapse chip connections (C4), ball grid arrays (BGAs), land grid arrays (LGAs), or bumps. In some embodiments, electrical contacts 14 can be used in fan-in structures, fan-out structures, or a combination of fan-in and fan-out structures. In some embodiments, the diameter of electrical contacts 14 ranges from approximately 0.2 millimeters (mm) to approximately 0.3 mm.

[0025] Figure 1B A top view of a semiconductor device package 1 according to some embodiments of the present invention is illustrated. In some embodiments, due to process limitations of photolithography, the lateral surface of dielectric layer 10 (e.g., surface 103) may not be parallel to the lateral surface of dielectric layer 11 (e.g., surface 113). For example, the distance between surface 103 of dielectric layer 10 and surface 113 of dielectric layer 11 may vary. In some embodiments, the distance between surface 103 of dielectric layer 10 and surface 113 of dielectric layer 11 satisfies the following inequality:

[0026] 0<|D11-D12|≦1μm,

[0027] Wherein D11 is the maximum distance between the surface 103 of the dielectric layer 10 and the surface 113 of the dielectric layer 11 , and D12 is the minimum distance between the surface 103 of the dielectric layer 10 and the surface 113 of the dielectric layer 11 .

[0028] In some existing processes for forming connection structures (e.g., fan-out structures) of semiconductor device packages, a circuit layer is placed on a carrier, with fine-pitch conductive traces (e.g., line spacing (L / S) equal to or less than 7 micrometers (μm) / 7 μm) on one side of the circuit layer (e.g., the chip side), and then coarse-pitch conductive traces are formed on the other side of the circuit layer (e.g., the ball side). However, due to the accuracy limitations of the bonder (or bonding machine), misalignment in the x-direction and / or y-direction will be greater than 2 μm, which will cause electrical problems (e.g., short circuits or opens) in the conductive traces, especially when the pitch of the conductive traces is scaled down (e.g., L / S equal to or less than 7 μm / 7 μm). According to Figure 1A and Figure 1B In the embodiment, since the conductive traces (eg, conductive layer 10r1) are formed by photolithography, the maximum misalignment in the x-direction and / or the y-direction is equal to or less than 1 μm, which facilitates the formation of the conductive traces with a large pitch.

[0029] Figure 2A A cross-sectional view illustrating a semiconductor device package 2A according to some embodiments of the present invention. The semiconductor device package 2A is similar to Figure 1A The semiconductor device package 1 in FIG. 2A further includes an underfill material 23 between the electronic component 12 and the dielectric layers 10 and 11. In some embodiments, the underfill material 23 includes an epoxy resin, a molding compound (e.g., epoxy molding compound or other molding compound), a polyimide, a phenolic compound or material, a material containing silicone dispersed therein, or a combination of two or more thereof. In some embodiments, depending on the specifications of different embodiments, the underfill material 23 may be a capillary underfill (CUF), a molded underfill (MUF), or an applied gel.

The semiconductor device package 2C is similar to Figure 1A 1 , except that semiconductor device package 2C further includes an electronic component 22 disposed on surface 112 of dielectric layer 11 and electrically connected to the conductive traces on the surface of dielectric layer 11. In some embodiments, semiconductor device package 2C may further include an underfill 22u between electronic component 22 and dielectric layer 11.

[0032] Figure 4E The cross-sectional view of a plurality of semiconductor device packages including a semiconductor device package 4 according to some embodiments of the present invention is illustrated. The semiconductor device package 4 includes a circuit layer 40, an electronic component 42, and a package body 43.

[0033] Circuit layer 40 may include conductive layers 40r1, 40r2, and 41r for providing electrical connections, and dielectric layers 40d and 41d covering portions of conductive layers 40r1, 40r2, and 41r. In some embodiments, dielectric layer 40d and / or dielectric layer 41d include a photosensitive material. In some embodiments, top surface 40d1 of dielectric layer 40d is lower than top surface 41d1 of dielectric layer 41d. For example, top surface 40d1 of dielectric layer 40d is recessed into top surface 41d1 of dielectric layer 41d.

[0034] Electronic component 42 is disposed on circuit layer 40 and contacts the portion of conductive layer 40r1 exposed from dielectric layer 40d. For example, electronic component 42 is disposed within a recess defined by dielectric layers 40d and 41d. Package body 43 is disposed on dielectric layers 40d and 41d to cover conductive layer 40r1 and electronic component 42.

In some embodiments, the dielectric layer 31 may have a Figure 1A The conductive layer 30r2 may have the same or similar properties as the dielectric layer 11 in the conductive layer 30r2. In some embodiments, the conductive layer 30r2 may be formed by: (i) removing the seed layer 30s by, for example, an etching process to expose the metal layer 30m; (ii) disposing a photoresist (e.g., a mask) on the metal layer 30m by, for example, coating; and (iv) performing an exposure, development, and etching process to form a plurality of openings in the photoresist to expose portions of the metal layer 30m; (v) removing the exposed portions of the metal layer 30m by, for example, an etching process; and (vi) removing the photoresist.

[0052] Figure 5A and 5B Different types of semiconductor device packages according to some embodiments of the present invention are described.

[0053] As in Figure 5A , a plurality of chips 50 and / or dies are disposed on a square carrier 51. In some embodiments, at least one of the chips 50 may include a semiconductor device package 1, 2A, 2B, 2C, or 4, as shown in FIG. Figure 1A 、 2A , 2B, 2C, or 4E. In some embodiments, the carrier 51 may include an organic material (e.g., molding compound, BT, PI, PBO, solder resist, ABF, PP, epoxy-based material, or a combination of two or more thereof) or an inorganic material (e.g., silicon, glass, ceramic, quartz, or a combination of two or more thereof).

[0054] As in Figure 5B , a plurality of chips 50 and / or dies are disposed on a circular carrier 52. In some embodiments, at least one of the chips 50 may include a semiconductor device package 1, 2A, 2B, 2C, or 4, as shown in FIG. Figure 1A 、 2A , 2B, 2C, or 4E. In some embodiments, carrier 52 may include an organic material (e.g., molding compound, BT, PI, PBO, solder resist, ABF, PP, epoxy-based material, or a combination of two or more thereof) or an inorganic material (e.g., silicon, glass, ceramic, quartz, or a combination of two or more thereof).

[0055] As used herein, the terms "approximately," "substantially," "substantially," and "about" are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms may refer to instances in which the event or circumstance occurred exactly as well as instances in which the event or circumstance occurred approximately. For example, when used in conjunction with a numerical value, the terms may refer to a range of variation of less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two values ​​is less than or equal to ±10% of the mean of the values ​​(e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), then the values ​​may be considered to be "substantially" or "approximately" the same. For example, "substantially" parallel may refer to an angular variation of less than or equal to ±10° relative to 0°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" perpendicular may refer to an angular variation of less than or equal to ±10° relative to 90°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

[0056] Two surfaces may be considered coplanar or substantially coplanar if the displacement between the two surfaces is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm.

[0057] As used herein, the terms "conductive," "electrically conductive," and "conductivity" refer to the ability to transmit an electric current. Conductive materials generally refer to those materials that exhibit little or no resistance to the flow of electric current. One measure of conductivity is Siemens per meter (S / m). Typically, a conductive material is one having a conductivity greater than about 10 4 S / m conductivity of the material, for example at least 10 5 S / m or at least 10 6 S / m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

[0058] As used herein, the singular terms "a," "an," and "the" may include plural referents unless the context clearly indicates otherwise. In the description of some embodiments, providing that a component is "on" or "over" another component may encompass situations where the latter component is directly on (e.g., physically contacting) the former component, as well as situations where one or more intervening components may be located between the former and latter components.

[0059] Although the present invention has been described and illustrated with reference to specific embodiments of the present invention, these descriptions and illustrations do not limit the present invention. It will be clearly understood by those skilled in the art that various changes may be made and equivalent components may be substituted within the embodiments without departing from the true spirit and scope of the present invention as defined by the accompanying claims. The descriptions may not necessarily be drawn to scale. Due to variables in the manufacturing process, etc., there may be differences between the exquisite presentation of the present invention and the actual device. There may be other embodiments of the present invention that are not specifically described. The description and drawings should be regarded as illustrative rather than restrictive. Modifications may be made to adapt specific circumstances, materials, compositions of matter, methods or processes to the purpose, spirit and scope of the present invention. All such modifications are intended to fall within the scope of the appended claims. Although the methods disclosed herein have been described with reference to specific operations performed in a specific order, it will be understood that these operations may be combined, subdivided or reordered to form equivalent methods without departing from the teachings of the present invention. Therefore, unless otherwise specified herein, the order and grouping of operations are not limitations of the present invention.
