DETAILED DESCRIPTION
The advantages and features of the present disclosure and methods of achieving them will be apparent from the following exemplary embodiments that will be described in more detail with reference to the accompanying drawings. It should be noted, however, that the disclosed embodiments are not limited to the following examples, and may be implemented in various forms.
In the specification, it will be understood that when an element is referred to as being “connected,” “coupled to,” or “on” another layer or substrate, it can be directly connected to, coupled to, or on the other element, or intervening elements may also be present. In the drawings, thicknesses of elements are exaggerated for clarity of illustration.
Exemplary embodiments will be described below with reference to cross-sectional views, which are exemplary drawings. The exemplary drawings may be modified by manufacturing techniques and/or tolerances. Accordingly, the exemplary embodiments are not limited to specific configurations shown in the drawings, and may include modifications based on the method of manufacturing the semiconductor device. For example, an etched region shown at a right angle may be formed in a rounded shape or formed to have a predetermined curvature. Therefore, regions shown in the drawings have schematic characteristics. In addition, the shapes of the regions shown in the drawings exemplify specific shapes of regions in an element, and are not intended to limit the invention.
Though terms like a first, a second, and a third are used to describe various elements in various embodiments, the elements are not limited to these terms. Unless indicated otherwise, these terms are used only to tell one element from another element. An embodiment described and exemplified herein includes a complementary embodiment thereof. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terms used in the present specification are used to describe a particular embodiment and are not used to limit the present invention. As in the present specification, a singular form may include a plural form unless the singular form definitely indicates otherwise in the context. Also, in the present specification, the terms “include,” “including,” “comprise” and/or “comprising” specify existence of shapes, numbers, steps, operations, members, elements, and/or groups thereof, which are referred to, and do not exclude existence or addition of one or more different shapes, numbers, operations, members, elements, and/or groups thereof.
The various exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings.
FIG. 1A is a cross-sectional view of a semiconductor package according to certain exemplary embodiments, FIG. 1B is a partial enlarged view of the semiconductor package shown in FIG. 1A, and FIG. 1C is a top plan view of the semiconductor package shown in FIG. 1A, according to an exemplary embodiment. FIG. 1A is a cross-sectional view taken along the line I-I′ in FIG. 1C, and FIG. 1B is an enlarged view of an “A” portion of the semiconductor package shown in FIG. 1A.
FIG. 1D is a top plan view illustrating an arrangement structure of first and second connection patterns of a semiconductor package according to one embodiment, and FIG. 1E is a top plan view illustrating an arrangement structure of first and second connection patterns of a semiconductor package according to another embodiment.
Referring to FIGS. 1A through 1C, a semiconductor package 10 may include a package substrate 150, an intermediate substrate 102, a semiconductor chip 104, and connection structures 170 electrically connecting the semiconductor chip 104 to the package substrate 150.
The semiconductor chip 104 may be disposed on a top surface of the intermediate substrate 102. In an example embodiment, the semiconductor chip 104 is disposed in a central portion of the intermediate substrate 102. In another example embodiment, the semiconductor chip 104 is disposed at an edge portion of the intermediate substrate 102. The semiconductor chip 104 and the intermediate substrate 102 may be electrically connected through a conductive terminal such as, for example, a bonding wire 106. Although a single semiconductor chip and intermediate substrate is shown, a plurality of stacked chips may be mounted on the intermediate substrate 102, using one or more chip stack technologies (e.g., wire bonding, through vias, etc.). The chips may be memory chips or logic chips. The chips may be the same sizes or different sizes, and may be stacked in different configurations (e.g., edge-aligned, step-wise alignment, mesa arrangement, spiral arrangement, zig-zag arrangement, etc.). In addition, or alternatively, a plurality of intermediate substrates may be connected to each other in a stack above package substrate 150, each including one or more stacked chips, to form a package having a package-on-package structure.
A first capacitor 108 may be disposed on the top surface of the intermediate substrate 102. According to certain embodiments, the first capacitor 108 is mounted on the top surface of the intermediate substrate 102 (surface mount technology; SMT). According to alternative embodiments, the first capacitor 108 may be embedded in the intermediate substrate 102. The intermediate substrate 102 may be, for example, a substrate that includes circuitry, through wires, and through vias for electrically connecting between the semiconductor chip 104 and the package substrate 150.
In one embodiment, the package substrate 150 includes a core portion C, a second capacitor 156 disposed within the core portion C, and buildup portions B disposed on a top surface and/or a rear surface of the core portion C. In FIG. 1A, it is exemplarily shown that the buildup portion B is disposed on the top surface of the core portion C.
Although not discussed in detail, the core portion C may include metal cores. An insulator may be disposed to fill a space between the metal cores. A second capacitor 156 may be disposed between the metal cores and electrically insulated from the metal cores by the insulator. For example, each of the metal cores may be made of stainless steel, aluminum, nickel, magnesium, zinc, tantalum or an alloy thereof. Circuit patterns 162 may be disposed in the buildup portions B, respectively. The circuit patterns 162 may be electrically connected to the metal cores. The circuit patterns 162 may be electrically connected to one another.
The second capacitor 156 may include a first electrode 152a, a second electrode 152b, and a dielectric film 154 disposed between the first and second electrodes 152a and 152b. The first and second electrodes 152a and 152b of the second capacitor 156 may be electrically connected to the circuit patterns 162 disposed in the buildup portion B, respectively. The circuit patterns 162 disposed in the buildup portion B may include a first wiring 160a connected to the first electrode 152a and a second wiring 160b connected to the second electrode 152b. The first wiring 160a and second wiring 160b may each be a conductive portion formed of a conductive material, and the first wiring 160a may be electrically separate from the second wiring 160b. The two wirings may be formed as a wiring pattern in the substrate, the wiring pattern including multiple separate wirings. As such, a first conductive portion (e.g., the first wiring 160a) of the circuit pattern 162 is electrically connected to the first electrode 152a, and a second conductive portion (e.g., the second wiring 160b) of the circuit pattern 162 is electrically connected to the second electrode 152b. Both the conductive portions and the electrodes may be positioned so that they are within the package substrate 150. For example, the conductive portions and electrodes may be disposed to have bottom surfaces that are raised above a bottom surface of the package substrate 150, and top surfaces that are disposed below a top surface the package substrate 150, such that they are entirely embedded in the package substrate 150.
In the package substrate 150, there may be at least one first via contact 158a electrically connected to the first wiring 160a and at least one second via contact 158b electrically connected to the second wiring 160b. The first and second via contacts 158a and 158b may electrically connect the internal connection patterns 166 with the first and second wirings 160a and 160b. The first and second via contacts 158a and 158b may be disposed vertically between the circuit patterns 162 and the internal connection patterns 166. This will be described in more detail below.
According to some embodiments, a first voltage may be applied to the first electrode 152a through the first wiring 160a, and a second voltage may be applied to the second electrode 152b through the second wiring 160b. The second voltage may be substantially different from the first voltage. For example, the first voltage may be a ground voltage, and the second voltage may be a power supply voltage applied to the package substrate 150.
Referring to FIGS. 1A through 1C, the top surface of the package substrate 150 may include a first region R1 in which the semiconductor chip 104 and the intermediate substrate 102 are disposed and a second region R2 formed to surround the first region R1. The top surface of the package substrate 150 may further include a separation region SR formed between the first and second regions R1 and R2. According to one embodiment, when the top surface of the package substrate 150 is viewed in plane, the first region R1 is disposed in a central portion to have a square shape, the separation region SR is disposed to surround the first region R1, and the second region R2 is disposed to surround the separation region SR.
The connection structures 170 may include internal connection patterns 166 (e.g., terminals, such as conductive balls or bumps) and external connection patterns 168 (e.g., terminals, such as conductive balls or bumps).
The internal connection patterns 166 may be disposed in the first region R1 of the package substrate 150. According to one embodiment, the internal connection patterns 166 electrically connect the package substrate 150 to the intermediate substrate 102 (e.g., by connecting to the embedded first or second wiring through the via contacts or other conductive contacts). According to one embodiment, the internal connection patterns 166 include nodes, such as balls or bumps, that directly connect to the package substrate 150 and to the intermediate substrate 102.
The external connection patterns 168 may be disposed in the second region R2 of the package substrate 150. In one embodiment, no connection terminals are included in separation region SR, so that the connection structure 170 is not disposed in the separation region SR.
According to some embodiments, the internal connection patterns 166 and the external connection patterns 168 may each include a plurality of terminals, or nodes, such as a plurality of solder bumps. For example, a plurality of solder bumps may be arranged and spaced at regular intervals in a Y-axis direction to constitute a string. Strings in the Y-axis direction may be arranged and spaced in an X-axis direction. Solder bumps arranged and spaced in the X-axis direction may be arranged zigzag. In the X-axis direction, a solder bump may be arranged at a space between two solder bumps arranged in the Y-axis direction to be adjacent to each other. For example, as shown in FIG. 1C, if the Y-axis is in the direction of a first edge of the package substrate 150 and the X-axis is in the direction of a second edge of the package substrate 150 perpendicular to the first edge, external connection terminals may be arranged in rows (or columns) in the Y-direction, wherein terminals in a first row are offset from terminals in an immediately adjacent second row such that a closest terminal in the first row to a given terminal in the second row is disposed diagonally from the given terminal with respect to the X and Y directions. However, this is only one exemplary embodiment, and other arrangements of the terminals may be used.
Exemplary arrangements of the internal connection patterns 166 will now be described below in detail.
The internal connection patterns 166 may include first and second connection patterns 164a and 164b (e.g., first and second sets, or groupings, of connection terminals). In one embodiment, the first connection pattern 164a is electrically connected to the first wiring 160a, and the second connection pattern 164b is electrically connected to the second wiring 160b. For example, in one embodiment, the first electrode 152a laterally covers the space of fewer than the total number of terminals in the first group of terminals 164a (e.g., it may vertically overlap only 1 or 2 terminals, or only a first and second row of terminals), but the first wiring 160a laterally covers the space (i.e. vertically overlaps) of all of the terminals in the first group of terminals 164a. Similarly, the second electrode 152b may laterally cover the space of fewer than the total number of terminals in the second group of terminals 164a (e.g., it may vertically overlap only 1 or 2 terminals, or only a first and second row of terminals), but the second wiring 160b may laterally cover the space (i.e. vertically overlap) all of the terminals in the second group of terminals 164b. The other electrodes shown but not labeled in FIG. 1C may include similar connections to terminals and wirings. As such, the capacitor electrodes can have a smaller size and cover a smaller area than the wirings and connection terminals, but can still electrically connect to all of the terminals in a group of terminals
In some embodiments, the first connection pattern 164a may be electrically connected to the first via contacts 158a and may be electrically connected to the first wiring 160a via the first via contacts 158a. For example, in the case that a plurality of the first via contacts 158a are provided, each of the first via contacts 158a may be electrically connected to a corresponding terminal of the first connection pattern 164a. The second connection patterns 164b may be electrically connected to the second via contact 158b and may be electrically connected to the second wiring 160b via the second via contacts 158b. For example, in the case that a plurality of the second via contacts 158b are provided, each of the second via contacts 158b may be electrically connected to a corresponding terminal of the second connection pattern 164b. As such, the first connection pattern 164a, first via contacts 158a, and first electrode 152a may all be considered a first node, and the second connection pattern 164b, second via contacts 158b, and second electrode 152b may all be considered a second node. The via contacts may be, for example, small sized through vias partially passing through the package substrate 150, for example disposed the buildup portion B between the wirings 160a and 160b. Alternatively, the via contacts may be wires embedded in the buildup portion B of the package substrate. Each via contact may be separated and electrically insulated from other via contacts by, for example, an insulating material in the buildup portion B of the package substrate.
The first wiring 160a (and thus the first node) may be connected to a first voltage (e.g., ground voltage) to receive the applied first voltage, and the second wiring 160b (and thus the second node) may be connected to a second voltage (e.g., power supply voltage) to receive the applied second voltage, wherein the first and second voltages are applied to the package substrate 150.
Referring to FIG. 1D, the first connection pattern 164a may constitute a first group structure G1 (i.e., a first terminal group). The first group structure G1 may include a plurality of first unit structures U1 (i.e., first terminal sub-groups). At least one of the first unit structures U1 may include, for example, one of the terminals of first connection pattern 164a and another four terminals of the first connection pattern 164a arranged therearound. The four outer connection terminals may be arranged equidistant from the inner connection terminal disposed in the center, and may thus form an X shape with minimal spacing between terminals.
The second connection patterns 164b may constitute a second group structure G2 (i.e., a second terminal group). The second group structure G2 may be disposed in a region that is spatially separated from the first group structure G1. For example, the first group structure G1 and second group structure G2 may be arranged in separate regions that do not overlap in a particular direction (e.g., the X-direction). The second group structure G2 may include a plurality of second unit structures U2 (i.e., second terminal sub-groups). At least one of the second unit structures U2 may include, for example, one of the terminals of second connection pattern 164b and other four of the second connection terminals arranged therearound. The four outer connection terminals may be arranged equidistant from the inner connection terminal disposed in the center, and may thus form an X shape with minimal spacing between terminals. As such, in one embodiment, each of the first group structure and the second group structure includes at least four connection terminals, each connection terminal adjacent to at least one connection terminal of that group structure in a first direction and also adjacent to at least a second connection terminal of that group structure in a second direction not parallel to the first direction.
According to some embodiments, the first group structure G1 may have a linear shape extending in the Y-axis direction. The second group structure G2 may also have a linear shape extending in the Y-axis direction. A plurality of first group structures G1 and a plurality of second group structures G2 may be provided, respectively, and may be arranged in an alternating manner. The first group structure G1 may be connected, for example, to a first voltage through a conductive portion (e.g., wiring), and the second group structures G2 may be connected, for example, to a second voltage through a second conductive portion (e.g., wiring). In one embodiment, each of the separate first group structures G1 connects separately from the other first group structures G1 to the first voltage (i.e., a power voltage source or ground), for example, through separate lines connected to the first voltage, and each of the separate second group structures G2 connects separately from the other second group structures G2 to the second voltage source (i.e., a power voltage source or ground), for example, through separate lines connected to the second voltage. According to one embodiment, it is assumed that a left side of the first region R1 is referred to as a first side L1, and the other sides are clockwise referred to as a second side L2, a third side L3, and a fourth side L4, respectively. Ends in a lengthwise direction of the respective first group structures G1 may extend to the second side L2 and the fourth side L4. In addition, ends in a lengthwise direction of the respective second group structures G2 may also extend to the second side L2 and the fourth side L4.
As another embodiment, as shown in FIG. 1E, a plurality of first group structures G1 may be provided. A second group structure G2 may be disposed between the first group structures G1 and may surround the first group structures G1. As such, only one second group structure G2 may be provided. Both lengthwise ends of each respective first group structure G1 may be spaced apart from the second side L2 and the fourth side L4 of the first region R1 by the second group structure G2.
As set forth above, the terminals of the first connection pattern 164a, which are electrically connected to each other via the first wiring 160a and the first via contacts 158a, may constitute the first group structure G1. And the terminals of the second connection pattern 164b, which are electrically connected to each other via the second wiring 160b and the second via contacts 158b, may constitute the second group structure G2. Thus, the first and second electrodes 152a and 152b of the second capacitor 156 may be more efficiently applied with a predetermined voltage. As a result, electrical characteristics of the semiconductor package 10 may be improved. Furthermore, stable electric pathways can be established by virtue of the plurality of the first and second via contacts. For example, a single voltage can be applied to a group of connection terminals in a single continuous region (e.g., the region covered by a unit structure) to supply voltage to those terminals.
FIGS. 2A and 2B are top plan views illustrating an arrangement structure of first and second connection patterns of a semiconductor package according to one exemplary embodiment.
In this embodiment, except for an arrangement structure of first and second connection patterns 164a and 164b, first and second via contacts 158a and 158b, first and second wirings 160a and 160b, and the number of second capacitors 156, a package substrate 150, an intermediate substrate 102, and a semiconductor chip 104 may be substantially identical to the package substrate 150, the intermediate substrate 102, and the semiconductor chip 104 described in the above embodiment with reference to FIGS. 1A and 1B and will not be described in further detail. The arrangement shown in FIG. 2A may include, for example, a greater number of capacitors (e.g., a greater number of first and second electrodes), and a greater number of separate wirings, than the arrangement shown in FIG. 1D, to provide different voltages or signals to the different group structures.
Referring to FIGS. 2A and 2B, when viewed in plane, a first group structure G1 may have a rectangular shape extending lengthwise in a Y-axis direction. A plurality of first group structures G1 may be provided. The plurality of first group structures G1 may be arranged in a matrix in X-axis and Y-axis directions. A second group structure G2 may be disposed between the first group structures G1. In one embodiment, only one second group structure G2 is provided.
As one embodiment, as shown in FIG. 2B, first group structures G1 disposed on the edge of a first region R1 may be in contact with a second side L2 and a fourth side L4, respectively and may be spaced apart from first and third sides L1 and L3 by a second group structure G2.
As another embodiment, as depicted in FIG. 2A, first group structures G1 disposed on the edge of a first region R1 may be spaced apart from first through fourth sides L1, L2, L3, and L4 by a second group structure G2, such that the second group structure G2 surrounds the first group structures G1.
FIGS. 3A and 3B are top plan views illustrating an arrangement structure of first and second connection patterns of a semiconductor package according to another exemplary embodiment.
In this embodiment, except for an arrangement structure of first and second connection patterns 164a and 164b, first and second via contacts 158a and 158b, first and second wirings 160a and 160b, and the number of second capacitors 156, a package substrate 150, an intermediate substrate 102, and a semiconductor chip 104, may be substantially identical to the package substrate 150, the intermediate substrate 102, the semiconductor chip 104 described in above embodiment with reference to FIGS. 1A and 1B and will not be described in further detail. The arrangement shown in FIG. 3A may include, for example, a smaller number of capacitors (e.g., a smaller number of first and second electrodes), and a smaller number of separate wirings, than the arrangement shown in FIG. 1D, to provide different voltages or signals to the different group structures
Referring to FIGS. 3A and 3B, a first group structure G1 may have a rectangular shape, or more particularly a square shape when viewed in plane. A plurality of first group structures G1 may be provided. More specifically, a first region R1 maybe divided into four sub-regions by virtual X-axis and Y-axis passing therethrough. Of the four sub-regions, a right upper region is referred to as a first quadrant Q1, and the other sub-regions are clockwise referred to as a second quadrant Q2, a third quadrant Q3, and a fourth quadrant Q4. Four first group structures G1 may be provided. The four first group structures G1 may be disposed in the first through fourth quadrants Q1, Q2, Q3, and Q4, respectively. A second group structure G2 may be disposed between the first group structures G1 to spatially separate the first group structures from each other, and may also surround the first group structures G1.
As one embodiment, as shown in FIG. 3A, first group structures G1 disposed on the edge of a first region R1 may be spaced apart from first through fourth sides L1, L2, L3, and L4 by a second group structure G2.
As another embodiment, as shown in FIG. 3B, first group structures G1 disposed in respective quadrants Q1, Q2, Q3, and Q4 may each have an L-shaped structure. More specifically, the first group structure G1 may be a structure in which a portion of a corner disposed adjacent to the center of the first region R1 is part of the second group structure G2. The first group structure G1 disposed in the third quadrant Q3 may have a shape of right “L”. The first group structure G1 disposed in the fourth quadrant Q4 may have a shape of “L” that is bilaterally symmetrical to the right “L”, and the first group structure G1 disposed in the second quadrant Q2 may have a shape of “L” that is vertically symmetrical to the right “L”.
