Definitions
- This disclosure relates generally to packaged semiconductor devices, and, in particular, to Ball Grid Array (BGA) packages for wireless devices.
- BGA Ball Grid Array
- Allowing devices to connect to computers through a wireless communication path and wirelessly networking groups of computers is one of the fastest growing segments of the PC industry.
- Present and emerging standing technologies in this field include IEEE 802.11 (versions a, b and g) also known as ‘WiFi’ available from (# sign used to prevent automatic hyperlinks)
- Ball Grid Array (BGA) packaging technology is a popular choice for packaging semiconductor devices, or “chips,” because BGAs offer advantages in space, cost and density over other packaging technologies. This is also true for semiconductor devices pertaining to wireless communications. Wireless devices tend to be quite sensitive to inductance, however, and it is advantageous to minimize the effects of inductance when designing, manufacturing and using wireless and other sensitive devices.

- Allowing devices to connect to computers through a wireless communication path and wirelessly networking groups of computers is one of the fastest growing segments of the PC industry.

- Ball Grid Array (BGA) packaging technology is a popular choice for packaging semiconductor devices, or “chips,” because BGAs offer advantages in space, cost and density over other packaging technologies. This is also true for semiconductor devices pertaining to wireless communications. Wireless devices tend to be quite sensitive to inductance, however, and it is advantageous to minimize the effects of inductance when designing, manufacturing and using wireless and other sensitive devices.

Thispackage 10 includes one or more devices or integratedcircuits 12, aBGA substrate 14,mold compound 16,gold wire 20 for wire bonds,epoxy resin 22 to adhere thedevices 12 to thesubstrate 14, and solder-balls 24 to make electrical connections to a circuit board (not shown), such as a line or slot card in a computer or other device. Theconventional BGA package 10 may pick up inductance from its connections, for example where abond wire 20 connects to a pad on thedevice 12, and through a trace to aball 24 which connects to a board which connects to an antenna (e.g., an antenna attached to the line card).

- An exemplary embodiment of a BGA package according to embodiments of the invention is described with reference to
FIG. 2 . This figure illustrates a perspective view of aBGA package 40 having an antenna traced, formed, produced, or otherwise attached directly on asubstrate 42 of theBGA package 40 itself. A circuit having a radio frequency (RF) input or output, or both is located in a circuit on adie 50. In one embodiment theantenna 44 may be coupled to apad 52 on thedie 50, while in other embodiments theantenna 44 may be coupled to a pin orball 56 or other connection on thewireless package 40. The purpose of connecting thetrace antenna 44 in this manner is to lower the series inductance between the RF circuit and its associated antenna, to reduce the overall inductance seen by the device, and to improve performance. Lowered inductance by using embodiments of the invention can lower insertion loss in the antenna system on the order of 1 or more dB's by reducing the number of connections the signal must travel through between the RF circuit on thedie 50 and theantenna 44. - In one embodiment the
antenna trace 44 may travel around the periphery of thedevice 40, but in other embodiments the trace may be laid elsewhere on device. In some embodiments, theantenna 44 may have an impedance matched to the atmospheric impedance. - The RF circuit on the die 50 may be a receiver or transmitter for any wireless technology. In particular, the wireless communications devices formed on the BGA 40 may include IEEE 802.11, HomeRF, Bluetooth, and other devices using the 2.4 GHz Industrial, Scientific, and Medical Band (ISM). The devices may also operate at frequencies below or above the ISM band. The circuit to which the
antenna 44 is attached may be used in devices such as mobile phone handsets, personal data assistants, palmtops, pocket personal computers, printers, scanners, digital cameras, game consoles, MP3 players, wireless network access points, and the like. - The
antenna 44 may be constructed in whole or in part from solder and/or other electrically conductive material that is adhesive, printable, patternable, sprayable, or meltable. Theantenna 44 may be entirely constructed from a length of solder and/or other electrically conductive material which is shaped into a desired pattern—serpentine, straight length, branched, etc. This process may entail melting the material or using a resist for patterning on theBGA substrate 40. Troughs having conductive surfaces or surfaces which collect and adhere flowable material may be disposed throughout or selectively dispersed on theBGA substrate 40, or, as described below, other circuit boards or other suitable surface so as to collect and hold the liquefied conductive material before it hardens. When solder and solder balls, which may be used to produce theantenna 44, are molten, they may cause a beneficial self centering effect on the integratedcircuit package 40 through surface tension effects. Alternatively, theantenna 44 may be formed by spraying an adhesive, electrically conductive material through a mask. Theantenna 44, if formed from a length of solder and/or other electrically conductive material, may be disposed upon the circuit board or the IC chip package. The application of flowable materials, such as solder, to form theantenna 44 should be well controlled, because applying too much, too little, or irregularly to form theantenna 44 may affect its radiation and pickup patterns from one manufactured antenna to the next. Precise control of the processing is important in manufacturing the antennas as well as the other components. - Various electrically conductive materials may be used to form the
antenna 44. For instance, theantenna 44 may be formed, at least in part, from a metal, such as copper, aluminum, nickel, bismuth, tungsten, silver, palladium, platinum, zinc, chromium, molybdenum, lead, antimony, tin, or gold, or a non-metallic conductive material, such as poly silicon. If solder material is used, it may contain two or more of the group consisting of lead, bismuth, tin, antimony, copper, silver, zinc, and indium and may be lead free, such as tin-silver solder or tin-indium solder. Different lengths of the antenna may be formed of different materials. For example, if theantenna 44 is partly formed in theintegrated circuit 50, partly formed through interconnection elements such as bonding wires, and partly formed on theBGA substrate 40, theantenna 44 may have a polysilicon section, a solder material section, a gold wire section, and a copper section to maximize space utilization in the device. Material characteristic matching may be applied to improve the antenna performance. - Dielectric material, such as a liquid epoxy resin, may be disposed or filled around the interconnection elements which form the
antenna 44 to reduce the overall length of theantenna 44, since coating theantenna 44 elements with a higher permittivity (i.e., dielectric) material may help capture RF energy for theantenna 44. The dielectric material may be applied in flowable form on theBGA substrate 40 by an applicator and then hardened by heat or other radiation. The dielectric material may be formed through resists which are patterned or etched. A consideration in selecting dielectric material of a certain permittivity is that the higher the permittivity, the more RF energy is reflected within the antenna and the more narrow banded the resultingantenna 44 performance. Alternatively, theantenna 44 may be formed on a dielectric substrate, such as ceramic substrate separately attached to theBGA substrate 40. - Another embodiment of a BGA package according to embodiments of the invention is described with reference to
FIG. 3 . This figure is a perspective view of aBGA package 60, similar to thepackage 40 ofFIG. 2 , except having anantenna 44 that is shaped in a “staggered” configuration. As before, theantenna 44 is coupled to an RF input or output circuit on thedie 50, and again theantenna 44 may have an impedance matched to the atmospheric impedance. - Having an
antenna 44 shaped in such a manner provides control to the fabricator over the overall length of theantenna 44. As described above, different length antennas perform differently for particular electromagnetic frequencies. Having control over the length of theantenna 44 allows the designer to select theappropriate length antenna 44 for the particular desired application. The length of theantenna 44 may be set for the center frequency of the operating band of the RF circuit on thedie 50. Further,multiple antennas 44 or antenna elements could be used to more precisely capture information contained in sub bands within the operating band. In some embodiments,multiple antennas 44 may be placed on thesubstrate 82 and may be switchably selectable. - In this embodiment, the
antenna 44 may be coupled to apad 52 on a die, and in other embodiments theantenna 44 may be coupled to a pin orball 56 or other connection on the wireless package. - The shape of the
antenna 44 is not limited to the two shapes illustrated inFIGS. 2 and 3 , but rather can take any form, shape, and/or orientation dependent on factors of application, performance, cost, etc. In some embodiments, theantenna 44 may be a loop, patch, dipole, and other type of antenna, as is known in the art. Additionally, theantenna 44 is not limited to single loop antennas, but may be practiced with a double loop, triple loop, or other types of loop antennas, including fractional loop antennas such as 1 and ¾ loop antennas. Embodiments of the invention are compatible with and capable of including patch or microstrip antennas, such as those described in U.S. Pat. No. 6.914,566. - The area of the
BGA substrate 42 and thecircuit board 50 where the antenna is disposed may be made so as to reduce or eliminate conductive elements which may interfere with the receipt or transmission of radio frequency energy. Also, it may be desirable to place theantenna 44 at or near the edge of theBGA substrate 42 to maximize the antenna's placement. -
FIG. 4 illustrates another embodiment of the invention. This figure is a cross sectional diagram of a BGA package having an integrated, stacked, antenna pad. In this embodiment, aBGA package 80 includes aBGA substrate 82 that provide support for one ormore devices 86. As described above, a circuit on one or more of thedevices 86 includes an RF input or output, or both. Thedevices 86 are adhered to the substrate, typically by anepoxy resin 84, and are surrounded bymold compound 88. Electrical connections between thedevices 86 and thesubstrate 82 are formed throughwires 90 and wire bonds. Also, as described above, pins orballs 92 connect theBGA package 80 to cards or other circuits. - This embodiment additionally includes an
antenna pad 94 mounted on theBGA package 80. Theantenna pad 94 itself may be a surface mounted antenna chip or a conductive element which is flexibly bound and largely insulated by a carrier material which has an adhesive side or mechanically attachable portion. An antenna 96 (not shown) may be integrated with, covered by, or attached to theantenna pad 94. Theantenna pad 94 is coupled to the RF input or output circuit on thedevice 86 through aconnection wire 98. The connection wire may be formed of the same material as thewires 90, or could be a different material. The material may be selected for its antenna properties, as described above. In other embodiments, theconnection wire 98 need not be a wire at all, but rather could be formed of a metal trace, film, solder bond, or other type of connection. - Connecting the antenna pad 94 (or antenna 96 directly) through the
connection wire 98 lowers the series inductance to the wireless device over conventional methods. This reduces the overall effect of inductance on the device. - The
antenna pad 94 andconnection wire 98 may be covered by a protective coating to protect it while it is being handled, moved, etc. Such a coating may be particular to covering antennas, such as described above, and may be selected based on the RF properties as well as mechanical properties. - The antenna 96 may have an impedance matched to the atmospheric impedance. In other embodiments, the
pad 94 could be enclosed by themold compound 88 of thedevice 80. Further, thepad 94 could be placed under thesubstrate 82, or could be embedded as a plane within thesubstrate 82. In yet other embodiments, thepad 94 could be any shape or cover any portion of thedevice 80, and thepad 94 does not necessarily have to cover the majority of the device like shown inFIG. 4 . All of these variations are specifically contemplated and envisioned as embodiments of the invention. -
FIG. 5 illustrates yet another embodiment of a BGA package according to embodiments of the invention. This embodiment is similar to the embodiment described above with reference toFIG. 4 , and like reference numbers denote like elements. In this embodiment, theantenna pad 94 is located to one side of the encapsulatedpackage 100, rather than above thepackage 80 as described with reference toFIG. 4 . Theantenna pad 94 may be attached to thesubstrate 82, and may be directly coupled to thedevice 86 through theconnection wire 98. Theantenna pad 94 situated such as illustrated inFIG. 5 enables a relatively easy connection of theconnection wire 98. Also, as described above, theconnection wire 98 need not be a wire, and could be a trace, film, or other method used to connect theantenna pad 94 to thedevice 86. Similar to as described above, theantenna pad 94 may be covered by a coating for protecting thepad 94 and theconnection wire 98. - Using techniques of embodiments of the invention taught with reference to
FIGS. 4 and 5 , embodiments of the invention can also include a helical antenna formed entirely within either a BGA package, such as those described in the aforementioned and incorporated US patent application Ser. No. 10/147,827. -
FIGS. 6A and 6B are schematic diagrams illustrating comparative inductances in prior art systems and those according to embodiments of the invention, respectively. With reference toFIG. 6A , a system 120 includes aBGA package 122 that has a die 126 mounted thereon. The die includes an RF circuit, as described above. Aninductance 128 is associated with a wire line that connects the die 126 to the edge of the BGA package, for example to a pin or solder ball. Aninductance 130 is associated with connecting anexternal antenna 134 to the pin or solder ball. As referenced inFIG. 6A , the inductance can be on the order of 0.1 to 0.3 nH, which introduces excess inductance, insertion losses, and other poor performance of the antenna system. -
FIG. 6B is a schematic diagram illustrating an antenna system 140 according to embodiments of the invention. The system 140 includes aBGA package 142, including adie 146. Differently than in the system 120 ofFIG. 6A , an antenna 150 is coupled directly to thedie 146, and does not travel through a separate pin or ball. This eliminates the effective series inductance (ESL) seen in prior art circuits that is associated with a pin or ball connection between a packaged die and the outside of the package. By removing this inductance, the performance of a wireless device may be improved. - It should be appreciated that reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Therefore, it is emphasized and should be appreciated that two or more references to “an embodiment” or “one embodiment” or “an alternative embodiment” in various portions of this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined as suitable in one or more embodiments of the invention.
