Technical Field
[0001]
[0001] This disclosure relates to semiconductor devices, and more particularly to semiconductor devices having a plurality of stacked passive devices.
Background Art
[0002]
[0002] Integrated circuit (IC) technology has achieved great progress in improving computing power through miniaturization of electrical components. An IC device can be implemented in the form of an IC chip having a set of circuits integrated thereon, including a plurality of active components (e.g., transistors) and passive components (e.g., diodes, capacitors, inductors, and / or resistors), and a layer of contacts and interconnects above the active and passive components. In some implementations, one or more IC chips can be physically carried and protected by an IC package based on a packaging substrate.
[0003]
[0003] In some implementations, embedded passive devices such as deep trench capacitors are incorporated into IC packaging for performance improvement and package size reduction. One factor driving the use of such embedded passive devices is the desire to obtain small form factor products with electrical performance equivalent to or better than that of their larger passive device counterparts. In some implementations, depending on the size and / or thickness of the packaging substrate and the process for embedding passive devices in the packaging substrate, the size of the passive device may need to match the thickness of the core of the packaging substrate, and the electrical characteristics of the passive device may be limited. In some implementations, passive devices embedded in the packaging substrate may not include an electrostatic discharge (ESD) protection circuit provided therein.
[0004]
[0004] Therefore, there is a need for a semiconductor device (which can be embedded in a packaging substrate as an embedded passive device) and a method for manufacturing such a semiconductor device. [Overview of the Initiative]

[0018]
[0029] Figure 1 is a cross-sectional view of an exemplary packaging substrate 100 in which a semiconductor device 106 is embedded, according to an aspect of the present disclosure. In this example, the packaging substrate 100 includes a core 102, the core 102 having a cavity 104 extending completely through the core 102. The semiconductor device 106 is disposed within the cavity 104. The semiconductor device 106 has a top surface 108 having metal terminals 110 that provide electrical connections to passive components (e.g., capacitors) configured within the semiconductor device 106.
[0019]
[0030] The packaging substrate 100 further includes a plurality of dielectric layers 112 covering the upper surface 116 of the core 102 and corresponding patterned metallization layers 114. The patterned metallization layers 118 are disposed on the upper surface 116 of the core 102 to provide electrical connections between the metal terminals 110 of the semiconductor device 106 and the patterned metallization layers 114. In one embodiment, the same dielectric resin material used to form the plurality of dielectric layers 112 may be used in the gap region 109 of the cavity 104, between the sidewall of the semiconductor device 106 and the sidewall of the cavity 104. Applying the dielectric resin to the semiconductor device 106 and into the gap region 109 helps to fix the semiconductor device 106 in the cavity 104 so that, once the dielectric resin has cured, the metal terminals 110 maintain electrical contact with the corresponding portions of the patterned metallization layers 118.
[0020]
[0031] In one embodiment, the uppermost patterned metallization layer 114 on the top surface 120 of the packaging substrate 100 is connected to a plurality of metal terminals 122. The patterned metallization layer 114 provides a conductive path between the metal terminals 110 and 122 of the semiconductor device 106. In one embodiment, the plurality of metal terminals 122 may be configured to connect to an electronic package of a surface mount device (not shown in Figure 1).
[0021]
[0032] In one embodiment, a further plurality of dielectric layers 132 and corresponding patterned metallization layers 134 cover the bottom surface 136 of the core 102. Here, a patterned metallization layer 138 is positioned on the bottom surface 136 of the core 102. The bottommost patterned metallization layer 134 on the bottom surface 140 of the packaging substrate 100 is connected to a plurality of metal terminals 142. The patterned metallization layer 134 provides a conductive path to the metal terminals 142. In one embodiment, the plurality of metal terminals 142 may be configured to connect to an electronic package of a further surface mount device (not shown in Figure 1) or to a circuit board for connection to other devices.
[0022]
[0033] In Figure 1, the semiconductor device 106 has a height H1 that is substantially the same as the thickness H2 of the core 102. During the manufacturing of the packaging substrate 100, the semiconductor device 106 is inserted into the cavity 104 before dielectric resin is injected to fill the gap region 109 between the cavity 104 and the semiconductor device 106. During insertion, the semiconductor device 106 is carefully aligned within the cavity 104 to ensure that the metal terminals 110 make proper contact with and electrically bond to the corresponding portions of the patterned metallization layer 118. In addition, the injection of dielectric resin into the gap region 109 should be carried out with care not to disturb the initial alignment of the semiconductor device 106. In one embodiment, once the dielectric resin has cured, it fixes the semiconductor device 106 in its proper position within the cavity 104.
[0023]
[0034] In a scenario where the height H1 of the semiconductor device 106 and the thickness H2 of the core 102 are substantially the same, the insertion of the semiconductor device 106 into the cavity 104, and the subsequent injection and curing of the dielectric resin, can be achieved using processing techniques as described with reference to Figure 1.
[0024]
[0035] In some embodiments, the thickness H2 of the core 102 may be about 760 micrometers or less. In some embodiments, the recent trend is to have a thicker core to address issues such as substrate warping control, and the thickness H2 of the core 102 may be greater than about 760 micrometers (μm), and may even be in the range of 1.2 millimeters (mm) to 1.8 mm.
[0025]
[0036] However, according to some current designs, the height H1 of a semiconductor device 106 consisting of a single passive device can be in the range of 20 μm to 780 μm. In some embodiments, according to this application, a semiconductor device having a plurality of stacked passive devices may have a height that can be adjusted to match the thickness of the core for a particular packaging task.
[0026]
[0037] In some embodiments, the passive devices described herein may be capacitors, inductors, resistors, or combinations thereof. Figure 2 is a cross-sectional view of an exemplary deep trench capacitor 200 according to an embodiment of this disclosure. In some embodiments, the passive devices usable on the packaging substrate 100 of Figure 1 may be capacitors configured based on the deep trench capacitor 200.
[0027]
[0038] In Figure 2, the deep trench capacitive structure 210 is disposed in trenches 220 of an insulator 204 on a substrate 202. The deep trench capacitive structure 210 may include a conductive layer 212, a dielectric layer 214, and a conductive layer 216. The dielectric layer 214 separates the conductive layer 212 from the conductive layer 216. The conductive layers 212 and 216 of the deep trench capacitive structure 210 form electrodes of a capacitor 200, which may be connected, for example, to terminals on the surface of the resulting passive device (e.g., the top surface 108 with metal terminals 110 of the semiconductor device 106 shown in Figure 1). In some scenarios, multiple capacitive structures may be formed from an array of deep trenches in the substrate, with the spaces between the electrode layers filled with an electrical insulator (e.g., a dielectric).
[0028]
[0039] In some embodiments, the conductive layer 212 and / or conductive layer 216 may include copper, tungsten, aluminum, or a combination thereof. In some embodiments, the conductive layer 212 and / or conductive layer 216 may include polysilicon, doped silicon, or a combination thereof. In some embodiments, the dielectric layer 214 may include silicon oxide, a high-k material (having a relative permittivity (k) greater than that of silicon dioxide), or a combination thereof.
[0029]
[0040] Figure 3 is a cross-sectional view of an exemplary semiconductor device 300 configured without stacked passive devices, according to an aspect of the present disclosure. In some aspects, the semiconductor device 300 may be used as the semiconductor device 106 shown in Figure 1. The semiconductor device 300 includes a substrate portion 310, a passive device portion 320, and a metallization portion 330 arranged in a stacked configuration, with the passive device portion 320 disposed between the substrate portion 310 and the metallization portion 330.

In some embodiments, the electrical terminal structures 352, 354, 356, and 358 may include copper pillars, conductive pads, solder, or a combination thereof.
[0031]
[0042] In some embodiments, the substrate portion 310 may include silicon, germanium, and / or gallium arsenide. In some embodiments, the substrate portion 310 may correspond to the substrate 202 shown in Figure 2. In some embodiments, the passivation layer 340 may include an oxide material (e.g., silicon dioxide) or a nitride material (e.g., silicon nitride).
[0032]
[0043] In some embodiments, the passive device portion 320 includes deep trench capacitive structures 321, 323, 325, 327, and 329, each of which may have a configuration corresponding to the deep trench capacitive structure 210 shown in Figure 2. In some embodiments, the metallization portion 330 may include an interlayer dielectric layer and a conductive layer (unlabeled). In some embodiments, the metallization portion 330 may electrically couple the deep trench capacitive structures 321, 323, 325, 327, and 329 in series or parallel to electrical terminal structures 352, 354, 356, and 358 to form one or more passive components. In some embodiments, the deep trench capacitive structures 321, 323, 325, 327, and 329 may be configured as a single capacitor, and the electrical terminal structures 352, 354, 356, and 358 may be divided into two subsets as separate electrical terminals of the resulting capacitor. In some embodiments, the deep trench capacitive structures 321, 323, 325, 327, and 329 may be configured as two capacitors, two of the electrical terminal structures 352, 354, 356, and 358 may be configured as electrical terminals of a first resulting capacitor, and the other two of the electrical terminal structures 352, 354, 356, and 358 may be configured as electrical terminals of a second resulting capacitor.
[0033]
[0044] In some embodiments, the height H3 of a semiconductor device 300 consisting of a single passive device may be in the range of 20 μm to 780 μm. In some embodiments, when the core thickness of the packaging substrate is much greater than 780 μm, the semiconductor device 300 may not be embedded in such a packaging substrate based on the packaging scheme shown in Figure 1 (for example, it may be inserted into a through-cavity of the core).

In this scenario, the second conductive structure (e.g., electrical terminal structure 442a) to be bonded to the first layer passive device 410 is located on the underside of the second layer passive device 430a and adjacent to the metallization portion 436a of the second layer passive device 430a. In some embodiments, the passive device portion 434a of the second layer passive device 430a may be located on top of the substrate portion 432a of the second layer passive device 430a (e.g., by inverting the second layer passive device 430a upside down, as shown in Figure 4). In this scenario, the second conductive structure to be joined to the first layer passive device 410 (for example, the electrical terminal structure 456a after inverting the second layer passive device 430a shown in Figure 4) may be located on the underside of the second layer passive device 430a and connected to the set of TSVs 444a of the second layer passive device 430a.
[0045]
[0056] In some embodiments, the substrate portion 412 of the first layer passive device 410 may not be further trimmed, and thus the thickness of the wafer substrate for manufacturing the first layer passive device 410 can be substantially maintained. In some embodiments, the thickness H4 of the first layer passive device 410 may be similar to the thickness H3 of the semiconductor device 300, and may be in the range of 20 μm to 780 μm. In some embodiments, the substrate portions 432a / 432a of the second layer passive devices 430a / 430b may be further trimmed, and thus may have a thickness smaller than the thickness of the wafer substrate for manufacturing the second layer passive devices 430a / 430b. Therefore, the thickness of the substrate portion 412 of the first layer passive device 410 may be greater than the thickness of the substrate portions 432a / 432b of one or more second layer passive devices 430a / 430b. In some embodiments, the thickness H4a / H4b of the second layer passive device 430a / 430b may be in the range of 20 μm to 100 μm.
[0046]
[0057] In some embodiments, the total thickness of the semiconductor device 400 can be adjusted based on the number of second-layer passive devices and the thickness of the second-layer passive devices (one or more) to match the core thickness for a particular packaging task. For example, if the first-layer passive device 410 has a thickness H4 of 780 μm and each of the second-layer passive devices 430a / 430b has a thickness H5a / H5b of 50 μm, the total thickness of stacking N second-layer passive devices will be (780 + 50 × N) μm. In some embodiments, the overall thickness of the semiconductor device 400 may be in the range of 1.2 mm to 1.8 mm.
[0047]
[0058] Furthermore, the resulting passive components of the semiconductor device 400 may have electrical properties based on the combined effects of at least the passive device portions 414, 434a, and / or 434b. In one example, the resulting passive component may be a capacitor, and its capacitance may be a combination of the capacitive elements of the passive device portions 414, 434a, and / or 434b. In another example, the resulting passive component may be an inductor, and its inductance may be a combination of the inductive elements of the passive device portions 414, 434a, and / or 434b. Thus, by stacking multiple passive devices, larger capacitances or inductances can be implemented within the same footprint as the semiconductor device 300.
[0048]

[0049]
[0060] As shown in Figure 5A, a structure 500A is provided. Structure 500A includes a first layer passive device 410. In some embodiments, the first layer passive device 410 includes a substrate portion 412, a passive device portion 414, and a metallization portion 416 arranged in a stacked configuration. The first layer passive device 410 further includes a passivation layer 418 and an electrical terminal structure 422 on the metallization portion 416. In some embodiments, the first layer passive device 410 may further include one or more ESD protection circuits 424 and 426 disposed in the substrate portion 412 of the first layer passive device 410 and electrically coupled to the passive device portion 414 of the first layer passive device 410.
[0050]
[0061] In some embodiments, the electrical terminal structure 422 may be a conductive structure in the form of a conductive pad and may contain copper. In some embodiments, after forming the electrical terminal structure 422 on the metallization portion 416, a passivation layer 418 may be formed by depositing a passivation material (e.g., an oxide material or a nitride material), and the upper surface of the first layer passive device 410 may be prepared based on a chemical-mechanical polishing (CMP) process followed by a surface cleaning process (e.g., a surface plasma cleaning process).
[0051]
[0062] As shown in Figure 5B, the second layer passive device 530a is added to the first layer passive device 410 to form structure 500B based on structure 500A. The second layer passive device 530a may include a substrate portion 532a, a passive device portion 434a, and a metallization portion 436a arranged in a stacked configuration. The second layer passive device 530a may include a set of TSVs 534a connected to the metallization portion 436a and extending into the substrate portion 532a. The second layer passive device 530a may further include a passivation layer 438a and an electrical terminal structure 442a adjacent to the metallization portion 436a.
[0052]
[0063] In some embodiments, the second layer passive device 530a may be manufactured in a similar manner to the first layer passive device 410 (except for the formation of TSVs in the substrate portion and the absence of ESD protection circuits), and then inverted upside down. The electrical terminal structure 442a may be a conductive structure in the form of a conductive pad, and the electrical terminal structures 422 and 442a may be joined by performing a fusion bonding process or a hybrid bonding process. In some embodiments, the electrical terminal structures 422 and 442a may be joined by other bonding processes, such as those based on soldering.
[0053]
[0064] As shown in Figure 5C, structure 500C is formed based on structure 500B by forming a second layer passive device 540a based on a second layer passive device 530a. In some embodiments, a portion of the substrate portion 532a of the second layer passive device 530a may be concave (e.g., based on a CMP process) to become a trimmed substrate portion 432a. A layer of etch-stop material (e.g., silicon nitride) may be deposited on the substrate portion 432a (e.g., based on a chemical vapor deposition (CVD) process), followed by a polishing process (e.g., based on a CMP process) to reduce the thickness of the etch-stop material layer to become an etch-stop layer 452a, and a set of TSV 534a is trimmed and exposed to become a set of TSV 444a.
[0054]
[0065] As shown in Figure 5D, structure 500D is formed based on structure 500C by forming a second layer passive device 430a based on a second layer passive device 540a. In some embodiments, a passivation layer 454a and an electrical terminal structure 456a may be formed above the etch stop layer 452a.
[0055]
[0066] As shown in Figure 5E, structure 500E is formed based on structure 500D by stacking another second-layer passive device 430b on top of the second-layer passive device 430a, based on the same operation as described with reference to Figures 5B and 5C.
[0056]
[0067] As shown in Figure 5F, structure 500F is formed based on structure 500E by forming electrical terminal structures 462, 464, 466, and 468 on the upper surface of the uppermost second layer passive device 430b. In some embodiments, the electrical terminal structures 462, 464, 466, and 468 may include copper pillars, conductive pads, solder, or a combination thereof.

[0064]
[0075] Various parts of the second layer passive devices 630a and 630b are shown as non-limiting examples. In some embodiments, different parts within each of the second layer passive devices 630a / 630b may be individually configured to be stacked in the same or reverse order as shown in Figure 6.
[0065]
[0076] In some embodiments, the semiconductor device 600 includes a passive component, which further includes a metallization portion 616 of a first-layer passive device 610, one or more sets of TSVs 644a / 644b of one or more second-layer passive devices 630a / 630b, and a passive component 614 of a first-layer passive device 610 electrically coupled to one or more passive device portions 634a / 634b of one or more second-layer passive devices 630a / 630b through one or more metallization portions 636a / 636b of one or more second-layer passive devices 630a / 630b.

In some embodiments, the electrical terminal structure 656a may be a third conductive structure in the form of a conductive pad, and the electrical terminal structure 642b may be a fourth conductive structure in the form of a conductive pillar bonded to the third conductive structure. In some embodiments, the third conductive structure may be connected to the fourth conductive structure by a solder joint (for example, the solder joint may not be labeled and shown as a block connecting the electrical terminal structures 656a and 642b, respectively).
[0067]
[0078] In some embodiments, the substrate portion 612 of the first layer passive device 610 may not be further trimmed, and thus the thickness of the wafer substrate for manufacturing the first layer passive device 610 can be substantially maintained. In some embodiments, the substrate portions 632a / 632a of the second layer passive devices 630a / 630b may be further trimmed, and thus they may have a thickness smaller than the thickness of the wafer substrate for manufacturing the second layer passive devices 630a / 630b. Therefore, the thickness of the substrate portion 612 of the first layer passive device 610 may be greater than the thickness of the substrate portions 632a / 632b of one or more second layer passive devices 630a / 630b.
[0068]
[0079] In some embodiments, similar to semiconductor device 400, the total thickness of semiconductor device 600 may be adjusted based on adjusting the number of second-layer passive devices and the thickness of the second-layer passive devices (one or more) to match the core thickness for a particular packaging task. In some embodiments, the overall thickness of semiconductor device 600 may be in the range of 1.2 mm to 1.8 mm. Furthermore, similar to semiconductor device 400, the resulting passive components of semiconductor device 600 may have electrical properties based on the combined effect of at least the passive device portions 614, 634a, and / or 634b. Thus, by stacking multiple passive devices, greater capacitance or inductance can be implemented within the same footprint as semiconductor device 300.
[0069]

Among the elements shown in Figures 7A to 7F, elements that are the same as or similar to those in the semiconductor device 600 of Figure 6 are given the same reference numerals, and their detailed descriptions may be omitted.
[0070]

In some embodiments, the first-layer passive device 610 includes a substrate portion 612, a passive device portion 614, and a metallization portion 616 arranged in a stacked configuration. The first-layer passive device 610 further includes a passivation layer 618 and an electrical terminal structure 622 on the metallization portion 616.

In some embodiments, structure 700A further includes a soldering structure 702 formed on the electrical terminal structure 622.
[0071]
[0082] In some embodiments, the electrical terminal structure 622 may be a conductive pad and may contain copper. In some embodiments, after forming the electrical terminal structure 622 on the metallization portion 616, a passivation layer 618 may be formed by depositing a passivation material (e.g., an oxide material or a nitride material), and the upper surface of the first layer passive device 610 may be prepared based on a chemical mechanical polishing (CMP) process followed by a surface cleaning process (e.g., a surface plasma cleaning process). Soldering material may then be deposited on the electrical terminal structure 622 to form a soldering structure 702.
[0072]
[0083] As shown in Figure 7B, structure 700B is formed based on structure 700A by attaching the second layer passive device 630a to the first layer passive device 610. The second layer passive device 630a may be a die manufactured and prepared to be stacked according to the present disclosure. In some embodiments, the electrical terminal structures 622 and 642a may be joined based on solder joints by solder joint structures 702. In some embodiments, if the second layer passive device 630a is not the top second layer passive device, the electrical terminal structure 656a may have a solder joint structure 704 stacked on top of it.
[0073]
[0084] As shown in Figure 7C, structure 700C is formed based on structure 700B by stacking all other second-layer passive devices (e.g., second-layer passive devices 630b) on the second-layer passive device 630a, based on the same operation as described with reference to Figure 7B.
[0074]
[0085] As shown in Figure 7D, structure 700D is formed based on structure 700C by arranging a molding material 710 on a first layer passive device 610 and surrounding one or more second layer passive devices 630a / 630b. In some embodiments, the molding material may include a resin. In some embodiments, the molding material may be deposited based on a molded underfill (MUF) process.
[0075]
[0086] As shown in Figure 7E, structure 700E is formed based on structure 700D by grinding the molding material 710 so that it becomes a sealing structure 670 and exposes the electrical terminal structures 662, 664, 666, and 668. In some embodiments, if the first layer passive device 610 in Figure 7A is an independent die, structure 700E may correspond to the semiconductor device 600.
[0076]
[0087] As shown in Figure 7F, if the first layer passive device 610 in Figure 7A is not a standalone die but part of the bottom wafer, a wafer dicing process can be performed, as shown in Figure 7F, which includes mounting the bottom wafer onto a dicing tape 720 and then cutting the bottom wafer based on a dicing saw or dicing laser 730 to separate structures 700F and 700F'. Each of structures 700F and 700F' may correspond to structure 700E.
[0077]
[0088] As shown in Figure 7G, structure 700G can be formed based on structure 700E or semiconductor device 600 by forming bump structures 742, 744, 746, and 748 on electrical terminal structures 662, 664, 666, and 668. In some embodiments, the bump structures 742, 744, 746, and 748 may be copper pillar bumps, solder bumps, or solder balls. In some embodiments, structure 700G may be an optional variation of structure 700E. In some embodiments, if the resulting semiconductor device is used inside a substrate core region, larger copper pads (e.g., electrical terminal structures 662, 664, 666, and 668) may be used for routing and connecting the substrate, and bump structures 742, 744, 746, and 748 as shown in Figure 7G may not be necessary.
[0078]
[0089] Figure 8 shows a method 800 for manufacturing semiconductor devices (such as semiconductor devices 400 and 600) according to an aspect of the present disclosure.
[0079]
[0090] In operation 810, a first layer passive device (e.g., first layer passive device 410 or 610) is provided. In some embodiments, the first layer passive device may include a substrate portion (e.g., substrate portion 412 or 612), a passive device portion (e.g., passive device portion 414 or 614), and a metallization portion (e.g., metallization portion 416 or 616), arranged in a stacked configuration. In some embodiments, the passive device portion may be disposed between the substrate portion and the metallization portion.
[0080]
[0091] In operation 820, one or more second-layer passive devices (e.g., second-layer passive devices 430a / 430b or 630a / 630b) may be stacked on top of a first-layer passive device (e.g., first-layer passive device 410 or 610) to form a semiconductor device (e.g., semiconductor device 400 or 600). In some embodiments, each of the one or more second-layer passive devices may include a substrate portion (e.g., substrate portions 432a / 432b or 632a / 632b), a passive device portion (e.g., passive device portion 434a / 434b or 634a / 634b), and a metallization portion (e.g., passive device portion 436a / 436b or 636a / 636b) arranged in a stacked configuration, wherein the passive device portion may be disposed between the substrate portion and the metallization portion.
[0081]
[0092] In operation 830, a passive component may be formed, the passive component including a metallization portion of a first layer passive device, one or more sets of TSVs of one or more second layer passive devices, and a passive component of a first layer passive device electrically coupled to one or more passive component portions of one or more second layer passive devices through one or more metallization portions of one or more second layer passive devices.
[0082]
[0093] In some embodiments, operation 820 may include mounting a first second layer passive device (e.g., second layer passive device 430a or 630a) of one or more second layer passive devices onto the upper surface of a first layer passive device (e.g., first layer passive device 410 or 610). In some embodiments, the first layer passive device may further include a first conductive structure disposed on the upper surface of the first layer passive device, the first second layer passive device may include a second conductive structure, and the first conductive structure may be bonded to the second conductive structure.
[0083]
[0094] In some embodiments, operation 820 may include performing a fusion bond or hybrid bond to connect the first conductive structure to the second conductive structure. In some embodiments, operation 820 may include forming a soldered structure that connects the first conductive structure to the second conductive structure.
[0084]
[0095] In some embodiments, operation 820 may include making a portion of the substrate of the first second layer passive device concave, and the substrate portion of the first second layer passive device may be disposed on top of the passive device portion of the first second layer passive device. In some embodiments, operation 820 may include forming a third conductive structure disposed on the upper surface of the first second layer passive device and connected to a set of TSVs of the first second layer passive device.
[0085]
[0096] In some embodiments, Method 800 may further include forming electrically coupled ESD protection circuits (e.g., ESD protection circuits 424 / 426 or 624 / 626) in the substrate portion of the first layer passive device, or in the passive device portion of the first layer passive device. In some embodiments, Method 800 may further include forming at least two electrical terminal structures (e.g., electrical terminal structures 462, 464, 466, and 468, or 662, 664, 666, and 668) on the upper surface of the uppermost second layer passive device (e.g., second layer passive device 430b or 630b) of one or more second layer passive devices, wherein at least two electrical terminal structures may be configured as electrical terminals of the passive components.
[0086]
[0097] In some embodiments, method 800 may further include arranging a molding material on a first layer passive device to form a sealing structure, surrounding one or more second layer passive devices.
[0087]
[0098] In some embodiments, Method 800 may further include forming a passive device portion of a first layer passive device and one or more passive device portions of one or more second layer passive devices, including a deep trench capacitor, an integrated stack capacitor, a metal-insulator-metal capacitor, a metal-oxide-metal capacitor, or a combination thereof.
[0088]
[0099] The technical advantage of Method 800 is that, with respect to the formation of a semiconductor device having multiple stacked passive devices, the thickness of the semiconductor device may be adjustable to match the thickness of the core for a particular packaging task. The first layer passive device of the semiconductor device may further include an ESD protection circuit. Also, based on the combined effect of the stacked passive devices, the electrical properties of the resulting passive component may be improved or enhanced. For example, a capacitor resulting from a semiconductor device formed based on multiple stacked passive devices as described above may have a capacitance based on the combined capacitances of all the capacitive structures of the stacked passive devices, and the resulting capacitor may have an increased capacitance value compared to a semiconductor device formed based on a single passive device and occupying the same footprint.

The package (e.g., 900) may be configured to provide Wireless Fidelity (WiFi) communications and / or cellular communications (e.g., 2G, 3G, 4G, 5G).
