[0001]     This Nonprovisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. 10-2005-0067808 filed in Korea on Jul. 26, 2005, the entire contents of which are hereby incorporated by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a semiconductor chip, more particularly, to a receiver chip which embodies receiver chips for terrestrial digital multimedia broadcasting (T-DMB), satellite digital multimedia broadcasting (S-DMB), or wireless broadband internet (WiBro) communications on one chip.

         [0006]     As shown in  FIG. 1A , a display device  140  displays images received through a S-DMB receiver chip  111  for receiving S-DMB signals and a T-DMB receiver chip  121  for receiving T-DMB signals.  
         [0007]     The signals outputted from the S-DMB receiver chip  111  are demodulated by a S-DMB demodulator  112 , and the demodulated signals are converted to image signals by an AV decoder  113  to be displayed on the display device  140 .  
         [0008]     In the same way, the signals outputted from the T-DMB receiver chip  121  are demodulated by a T-DMB demodulator  122 , and the demodulated signals are converted to image signals by an AV decoder  123  to be displayed on the display device  140 .  
         [0009]     Therefore, all of the S-DMB, T-DMB receiver chip  111  and  121 , the demodulators  112  and  122 , and the AV decoders  113  and  123  are required to configure the receiver in order to receive S-DMB signal and T-DMB signal, each having different receiving bandwidth, respectively.  
         [0010]     As a result, this configuration has shortcomings to increase its volume and power consumption and complicate the manufacturing process then to deteriorate the productivity.  
         [0011]      FIG. 1B  and  FIG. 1C  are block diagrams illustrating conventional receivers configured with receiver chips each having different receiving bandwidth, respectively.  
         [0012]     As shown in  FIG. 1B , a display device  140  displays images received  140  through a S-DMB receiver chip  111  for receiving S-DMB signals and a WiBro receiver chip  131  for receiving WiBro signals.  
         [0013]     The signals outputted from the S-DMB receiver chip  111  are demodulated by a S-DMB demodulator  112 , and the demodulated signals are converted to image signals by an AV decoder  113  to be displayed on the display device  140 .  
         [0014]     Likewise, the signals outputted from the WiBro receiver chip  131  are processed by a WiBro processor  132  to be displayed on the display device  140 .  
         [0015]     Herein, the term of WiBro is an abbreviated word of the wireless broadband internet and designates a wireless mobile internet service to display images on a display device via the wireless internet.  
         [0016]     As shown in  FIG. 1C , a display device  140  displays images received through a T-DMB receiver chip  121  for receiving T-DMB signals and a WiBro receiver chip  131  for receiving WiBro signals.  
         [0017]     The receiver with the T-DMB receiver chip  121  and the WiBro receiver chip  131  can be understood by the explanation of  FIG. 1B .  
         [0018]     These receivers illustrated  FIG. 1B  and  FIG. 1C  also have shortcomings to increase their volume and power consumption and complicate the manufacturing process then to deteriorate the productivity.

         [0045]      FIG. 2  is a block diagram illustrating one-chip receiver capable of receiving T-DMB and S-DMB signals in accordance with an exemplary embodiment of the present invention.  
         [0046]     As shown in  FIG. 2 , a receiver chip  200  comprises a S-DMB receiver chip  210  and a T-DMB receiver chip  220 . A demodulator  230  extracts broadcasting signals from the received signals from the receiver chip  200 , and then a decoder  240  extracts image signals to display S-DMB or T-DMB images on a display device  250 .  
         [0047]     In this configuration, the S-DMB receiver chip  210  and the T-DMB receiver chip  220  are single packaged by using System-in-Package (SiP) technology, and the pins capable of being shared are packaged to be interconnected each other so that the minimum pins are formed outside the receiver chip  200 .  
         [0048]     Using the single packaged receiver chip  200 , the receiver performance improves since the receiver is configured with only one modulator  230  and decoder  240 .

         [0055]     Using the single packaged receiver chip  300 , the overall performance of the receiver improves.  
         [0056]     Also, the single receiver chip  300  can minimize the area and lower the power consumption.  
         [0057]     Herein, if the S-DMB receiver chip  310  is configured with a dual S-DMB receiver chip using a diversity technique, the S-DMB receiving performance can further improve.

         [0059]     As shown in  FIG. 4 , a receiver chip  400  comprises a T-DMB receiver chip  410  and a WiBro receiver chip  420 . A demodulator  430  extracts broadcasting signals from the received signals from the T-DMB receiver chip  410 , and then a decoder  440  extracts image signals to display T-DMB images on a display device  450 . The signals received from the WiBro receiver chip  420  are processed by a processor  460  to be displayed on the display device  450 .  
         [0060]     Herein, the WiBro designates a wireless mobile internet service to display images on the display device  450  via the wireless internet.  
         [0061]     In this configuration, the T-DMB receiver chip  410  and the WiBro receiver chip  420  are single packaged by using SiP technology, and the pins capable of being shared are packaged to be interconnected each other so that the minimum pins are formed outside the receiver chip  400   
         [0062]     Using the single packaged receiver chip  400 , the overall performance of the receiver improves.  
         [0063]     Also, the single receiver chip  400  can minimize the area and lower the power consumption.

         [0065]     Herein, the two receiver chips may be the combinations of two of a S-DMB receiver chip, a diversity S-DMB receiver chip, a T-DMB receiver chip, or a WiBro receiver chip.  
         [0066]     Although S-DMB and T-DMB receiver chips are described as an example in this specification, it will be apparent that the two receiver chips may be S-DMB and T-DMB receiver chips, S-DMB and WiBro receiver chips, T-DMB and WiBro receiver chips, or diversity S-DMB and WiBro receiver chips to those skilled in the art.  
         [0067]     As shown  FIG. 5 , a S-DMB receiver chip  510  is disposed on a monolithic semiconductor integrated circuit substrate  530  and isolated from the outside. A T-DMB receiver chip  520  is stacked and bonded on the S-DMB receiver chip  510 .  
         [0068]     The T-DMB receiver chip  520  comprises a first bonding portion comprising m pads for receiving T-DMB signals, where m is a natural number. The S-DMB receiver chip  510  comprises a second bonding portion comprising n pads for receiving S-DMB signals, where n is a natural number.

         [0071]     As a result, the number of the pads of the third bonding portion, k, is smaller than the sum of the number of the pads of the first bonding portion, m, and the number of the pads of the second bonding portion, n, that is, k&lt;m+n.  
         [0072]     Also, if the S-DMB receiver chip  510  is configured with a receiver chip using the diversity technology, the overall size of the receiver is reduced than that of the conventional receiver configured with the respective receiver chips.  
         [0073]     Herein, if the S-DMB receiver chip  510  does not use the diversity technology, the stacking order of the S-DMB and T-DMB receiver chip  510  and  520  may change.  
         [0074]     That is, the S-DMB receiver chip  510  may be stacked on the T-DMB receiver chip  520 .  
         [0075]     This configuration can reduce the power consumption of the receiver by stacking and bonding two receiver chips on the monolithic semiconductor integrated circuit substrate and by wire-bonding the pads which can be shared by the two receiver chips.  
         [0076]      FIG. 6  is a view for describing packaging one-chip receiver by bonding two receiver chips adjacently to each other on a monolithic semiconductor integrated circuit substrate and by interconnecting the pads capable of being shared in the two receiver chips in accordance with another embodiment of the present invention.  
         [0077]     Herein, the two receiver chips may be the combinations of two of a S-DMB receiver chip, a diversity S-DMB receiver chip, a T-DMB receiver chip, or a WiBro receiver chip.  
         [0078]     Although S-DMB and T-DMB receiver chips are described as an example in this specification, it will be apparent that the two receiver chips may be S-DMB and T-DMB receiver chips, S-DMB and WiBro receiver chips, T-DMB and WiBro receiver chips, or diversity S-DMB and WiBro receiver chips to those skilled in the art.  
         [0079]     As shown  FIG. 6 , a S-DMB receiver chip  610  is disposed on a monolithic semiconductor integrated circuit substrate  630  and isolated from the outside. A T-DMB receiver chip  620  is bonded adjacently to the S-DMB receiver chip  610  and isolated from the outside.  
         [0080]     The T-DMB receiver chip  620  comprises a first bonding portion comprising m pads for receiving T-DMB signals, where m is a natural number. The S-DMB receiver chip  610  comprises a second bonding portion comprising n pads for receiving S-DMB signals, where n is a natural number.  
         [0081]     The T-DMB and S-DMB receiver chips  610  and  620  are bonded adjacently to each other on the monolithic semiconductor integrated circuit substrate  630  which comprises a third bonding portion comprising k pads, where k is a natural number, and the pads of the first and second bonding portions are wire-bonded to the third bonding portion of the monolithic semiconductor integrated circuit substrate to be packaged.  
         [0082]     That is, the pads  640  which can be shared in the S-DMB and T-DMB receiver chips  610  and  620  are wire-bonded between the receiver chips in the package.  
         [0083]     As a result, the number of the pads of the third bonding portion, k, is smaller than the sum of the number of the pads of the first bonding portion, m, and the number of the pads of the second bonding portion, n, that is, k&lt;m+n.  
         [0084]     Also, if the S-DMB receiver chip  610  is configured with a receiver chip using the diversity technology, the overall size of the receiver is reduced than that of the conventional receiver configured with the respective receiver chips.  
         [0085]     This configuration can reduce the power consumption of the receiver by bonding two receiver chips adjacently to each other on the monolithic semiconductor integrated circuit substrate and by wire-bonding the pads which can be shared by the two receiver chips.  
         [0086]      FIG. 7  is a view for describing packaging one-chip receiver by forming and embodying two receiving blocks and a common block capable of being shared by the two receiving blocks on a monolithic semiconductor integrated circuit substrate in accordance with another embodiment of the present invention.  
         [0087]     Herein, the two receiving blocks may be the combinations of two of a S-DMB receiving block, a diversity S-DMB receiving block, a T-DMB receiving block, or a WiBro receiving block.  
         [0088]     Although S-DMB and T-DMB receiving blocks are described as an example in this specification, it will be apparent that the two receiving blocks may be S-DMB and T-DMB receiving blocks, S-DMB and WiBro receiving blocks, T-DMB and WiBro receiving blocks, or diversity S-DMB and WiBro receiving blocks to those skilled in the art.  
         [0089]     As shown  FIG. 7 , a S-DMB receiving block  710 , a T-DMB receiving block  720 , and a common block (not shown) are formed in one chip  740  and bonded on a monolithic semiconductor integrated circuit substrate  730 .  
         [0090]     Herein, the common block is configured with circuits commonly used in the S-DMB and T-DMB receiving blocks  710  and  720 , such as a phase locked loop, a local oscillator, or a phase local oscillator.  
         [0091]     If the S-DMB receiving block  710  is configured with a receiving block using the diversity technology, the overall size of the receiver is reduced than that of the conventional receiver configured with the respective receiver chips.  
         [0092]     This configuration can reduce the power consumption of the receiver by forming two receiving blocks and the common block which can be used commonly in the two receiving blocks in one chip and by bonding the blocks on the monolithic semiconductor integrated circuit substrate.  
         [0093]      FIG. 8  is an example of one-chip receiver packaged by stacking and bonding two receiver chips on a monolithic semiconductor integrated circuit substrate and by interconnecting the pads capable of to be shared in the two receiver chips in accordance with an embodiment of the present invention.  
         [0094]     Herein, the two receiver chips may be the combinations of two of a S-DMB receiver chip, a diversity S-DMB receiver chip, a T-DMB receiver chip, or a WiBro receiver chip.  
         [0095]     Although S-DMB and T-DMB receiver chips are described as an example in this specification, it will be apparent that the two receiver chips may be S-DMB and T-DMB receiver chips, S-DMB and WiBro receiver chips, T-DMB and WiBro receiver chips, or diversity S-DMB and WiBro receiver chips to those skilled in the art.  
         [0096]     As shown  FIG. 8 , a T-DMB receiver chip  820  is stacked on a S-DMB receiver chip  810 , and pads  830  which can be shared by the S-DMB and T-DMB receiver chip  810  and  820  are interconnected with wire-bonding.  
         [0097]     That is, by packaging and interconnecting the pads which can be shared, the number of pins extruded out of the outside is reduced than that of the conventional receiver configured with the respective receiver chips.  
         [0098]     This configuration can reduce the volume and power consumption of the receiver, and simplify the receiving end circuitry and the manufacturing process so as to increase the productivity.  
         [0099]     As described above, the present invention can reduce the power consumption of the receiver by forming a receiver chip for forming receiving paths of dual frequency bandwidths on a monolithic semiconductor integrated circuit substrate.  
         [0100]     Also, the present invention can minimize the receiver by forming a receiver chip for forming receiving paths of dual frequency bandwidths on a monolithic semiconductor integrated circuit substrate.  
         [0101]     The foregoing exemplary embodiments and aspects of the invention are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
