No. 13/644,197, filed Oct. 3, 2012, which is based on and claims priority of Japanese Patent Application No. 2011-219943 filed on Oct. 4, 2011, the disclosures of which are expressly incorporated by reference herein.
- The present invention relates to a socket to which a test carrier, in which a die chip or other electronic device in which an integrated circuit or other electronic circuit is formed is temporarily mounted, is electrically connected and to an electronic device test apparatus which comprises that socket,
- Known in the art is a test carrier which comprises a contact sheet having a thickness 0.05 to 0.1 mm or so film made of polyimide on which contact pads and interconnect patterns are formed. The contact pads correspond to electrode patterns of a chip under test and the interconnect patterns are connected to the contact pads and secure contact with an external test apparatus (for example, see PLT 1).
- PLT 1: Japanese Patent Publication No. 7-263504 A1
- If the density of the contact pads or interconnect patterns becomes higher, sometimes the stress at the time of formation of the interconnects causes slight waviness to the thin film of the contact sheet. If waviness occurs in the film of the contact sheet, a spot where the contact pad is not electrically connected with the electrode of the chip will arise and there is the problem that contact defects will sometimes occur.
- The technical problem of the present invention is the provision of a socket and an electronic test apparatus which can suppress the occurrence of contact defects.

-
FIG. 1 is a flow chart which shows part of a device production process in the present embodiment. - In the present embodiment, after a semiconductor wafer is diced (after step S10 of
FIG. 1 ) and before the final packaging (before step S50), the electronic circuits which are built into adie 50 are tested (step S20 to S40). - In the present embodiment, first, a carrier assembly apparatus (not shown) is used to temporarily mount the die 50 into a test carrier 20 (step S20). Next, through this
test carrier 20, the die 50 and thetest circuit 15 of the electronic device test apparatus 10 (seeFIG. 7 ) are electrically connected and the electronic circuits which are built into the die 50 are tested (step S30). Further, after this test, the die 50 is taken out from the test carrier 20 (step S40), then the die 50 is packaged whereby the device is completed as a final product (step S50). - First, the configuration of the
test carrier 20 into which thedie 50 is temporarily mounted (provisionally packaged) for the test in the present embodiment will be explained while referring toFIG. 2 toFIG. 6 . -
FIG. 2 toFIG. 5 are views which show a test carrier in the present embodiment, whileFIG. 6 is a plan view which shows a base member of the test carrier. - A
test carrier 20 in the present embodiment, as shown inFIG. 2 toFIG. 4 , comprises: abase member 30 on which adie 50 is placed; and acover member 40 which is covered over thebase member 30, Thistest carrier 20 holds thedie 50 by having the die 50 interposed between thebase member 30 and thecover member 40 in a state reduced in pressure from atmospheric pressure. - The
base member 30 comprises abase frame 31 and abase film 32. Note that, thebase film 32 in the present embodiment is equivalent to one example of the first member in the present invention. - The
base frame 31 is a rigid board which has a high rigidity (at least a rigidity higher than thebase film 32 or the cover film 42) and is formed with anopening 31 a at its center. As the material which forms thisbase frame 31, for example, a polyamide imide resin, ceramic, glass, etc. may be mentioned. - On the other hand, the
base film 32 is a film which has flexibility. It is attached to the entire surface of thebase frame 31, including the center opening 31 a, through a binder (not shown). In this way, in the present embodiment, abase frame 31 with a high rigidity is attached to thebase film 32 which has flexibility, so the handling ability of thebase member 30 is improved. Note that, it is also possible to omit thebase frame 31 and form thebase member 30 by only thebase film 32. - As shown in
FIG. 5 , thisbase film 32 has: abase layer 322 on whichinterconnect patterns 321 are formed; and acover layer 323 which covers thisbase layer 322 through an adhesive layer (not shown). Both of thebase layer 322 and thecover layer 323 of thebase film 32 comprise, for example, polyimide films. Theinterconnect patterns 321 are, for example, formed by etching copper foil which is laminated on thebase layer 322. Note that, thecover layer 323 may also be omitted and theinterconnect patterns 321 may be exposed on thebase film 30. - As shown in
FIG. 5 andFIG. 6 , one end of eachinterconnect pattern 321 is exposed through anopening 323 a which is formed in thecover layer 323. Abump 324 to which anelectrode pad 41 of the die 50 is to be connected is formed on it. Thebump 324 is, for example, composed of copper (Cu), nickel (Ni), etc. For example, the semi-additive method is used to form it on the end part of theinterconnect pattern 321. Thisbump 324 is arranged so as to correspond to anelectrode pad 41 of the die 50. - On the other hand, the position on the
base frame 31 corresponding to the other end of theinterconnect pattern 321 has a throughhole 311 passing through it. Theinterconnect pattern 321 is connected through anopening 322 a which is formed in thebase layer 322 to the throughhole 311. This throughhole 311 is connected to anexternal terminal 312 which is formed on the bottom surface of thebase frame 31. This external terminal 33 is contacted by a later explainedcontactor 125 of a electronicdevice test apparatus 10 when testing the electronic circuit which is built into thedie 50. - Incidentally,
FIG. 5 only shows twoelectrode pads 51, but in actuality, thedie 50 is formed with a large number ofelectrode pads 51 at a narrow pitch. On thebase film 32 as well, a large number ofbumps 324 are arranged at a narrow pitch so as to correspond to theelectrode pads 51. Thebump 324 in the present embodiment is equivalent to one example of an internal terminal in the present invention. The die 50 in the present embodiment is equivalent to one example of an electronic device in the present invention, while theelectrode pad 51 in the present embodiment is equivalent to one example of an electrode of the present invention. - Note that, the
interconnect patterns 321 are not limited to the above configurations. For example, while not particularly shown, part of theinterconnect patterns 321 may also be formed in real time by ink jet printing on the front surface of thebase film 32. Alternatively, all of theinterconnect patterns 321 may be formed by ink jet printing. - Further, the other ends of the
interconnect patterns 321 may be positioned at the inside of the center opening 31 a of thebase frame 31 so as to form theexternal terminals 312 on the back surface of thebase film 32. Alternatively, the other ends of theinterconnect patterns 321 may be exposed on the top sides andexternal terminals 312 may be formed on the top surface of thebase film 32. - As shown in
FIG. 2 toFIG. 4 , thecover member 40 comprises acover frame 41 and acover film 42. Thecover film 42 in the present embodiment is equivalent to one example of the second member of the present invention. - The
cover frame 41 is a rigid board which has a high rigidity (at least a rigidity higher than thebase film 32 or the cover film 42) and is formed with anopening 41 a at its center. In the present embodiment, thiscover frame 41, in the same way as the above-mentionedbase frame 31, is for example composed of a polyamide imide resin, ceramic, glass, etc. - On the other hand, the
cover film 42 is a film which has flexibility and is attached to the entire surface of thecover frame 41, including the center opening 41 a, through a binder (not shown). In the present embodiment, since thecover frame 41 with a high rigidity is attached to thecover film 42 which has flexibility, the handling ability of thecover member 40 is improved. Note that, thecover member 40 may also comprise only thecover film 42. Alternatively, thecover member 40 may also comprise only a rigid board which is not formed with the opening 41 a. - Further, for example when both the top and bottom surfaces of the die 50 are formed with
electrode pads 51, in addition to thebase member 30, thecover member 40 can also he formed with interconnect patterns. In this case, by the same procedure with the above-mentionedbase frame 31 andbase film 32, thecover frame 41 is formed with external terminals and through holes and thecover film 42 is formed with interconnect patterns or bumps. - The above explained
test carrier 20 is assembled as explained next. - That is, first, in the state where the
electrode pads 51 are aligned with thebumps 324, thedie 50 is placed on thebase member 30. - Next, under an environment which is reduced in pressure compared with atmospheric pressure, the
cover member 40 is laid over thebase member 30 and thedie 50 is interposed between thebase member 30 and thecover member 40. At this time, thebase film 32 of thebase member 30 and thecover film 42 of thecover member 40 are made to directly contact each other by thecover member 40 being laid on thebase member 30. - Next, still in the state with the die 50 interposed between the
base member 30 and thecover member 50, thetest carrier 20 is returned to an atmospheric pressure environment so that thedie 40 is held in the holding space 21 (seeFIG. 3 ) which is formed between thebase member 30 and the cover member. - Incidentally, the
electrode pads 51 of thedie 50 and thebumps 324 of thebase film 32 are not fastened by solder etc. In the present embodiment, the space between thebase member 30 and thecover member 40 is a negative pressure compared with atmospheric pressure, so the die 50 is pressed by thebase film 32 and thecover film 42 and theelectrode pads 41 of thedie 50 and thebumps 324 of thebase film 32 contact each other. - Note that, as shown in
FIG. 3 , thebase member 30 and thecover member 40 may also be fastened to each other at a bondedpart 325 so as to prevent positional deviation and to improve the seal. As thebinder 326 which forms this bonded part 325 (seeFIG. 2 andFIG. 4 toFIG. 6 ), for example, a UV curing type binder etc. may be illustrated. Thisbinder 326 is coated in advance on thebase member 30 at positions corresponding to the outer periphery of thecover member 40, thebase member 30 is covered with thecover member 40, then UV rays are irradiated to cure that binder whereby the bondedpart 325 is formed. - Further, when the
die 50 is relatively thick, conversely from the configuration which is shown inFIG. 3 , thebase member 30 and thecover member 40 may be superposed so that therigid board 31 and therigid board 41 directly contact each other. - Further, in the present embodiment, as explained later, the pushing
mechanism 13 is used to push thebase film 32, so the space between thebase member 30 and thecover member 40 need not be reduced in pressure. - Next, the configuration of the electronic
device test apparatus 10, which is used for testing (FIG. 1 , step S30) of the die 50 which has been provisionally packaged in thetest carrier 20, will be explained while referring toFIG. 7 toFIG. 12 . Note that, the configuration of the electronicdevice test apparatus 10 which is explained below is only one example. The invention is not particularly limited to this. -
FIG. 7 is a cross-sectional view which shows the configuration of an electronic device test apparatus in the present embodiment,FIG. 8 is a cross-sectional view which shows the configuration of the pushing mechanism in the present embodiment,FIG. 9 andFIG. 10 are cross-sectional views which show modifications of the pushing mechanism in the present embodiment,FIG. 11 is a cross-sectional view which shows a base film of a test carrier which is pushed by the pushing mechanism which is shown inFIG. 8 , andFIG. 12 is a cross-sectional view which shows a modification of an electronic device test apparatus in the present embodiment. - The electronic
device test apparatus 10 in the present embodiment, as shown inFIG. 7 , comprises asocket 11, board 14,test circuit 15, andtemperature regulating head 16. Further, thesocket 11 has: apocket 12 in which thetest carrier 20 is to be placed; and a pushingmechanism 13 which pushes thebase film 32 of thetest carrier 20. - The
pocket 12 has arecess 121 which can accommodate thetest carrier 20. At the outer circumferential part of thisrecess 121, astopper 122 which has aseal member 123 at the top is provided extending along the entire circumference. As theseal member 123, for example, a rubber packing etc. can be used. When the outer periphery of thetest carrier 20 abuts against theseal member 123, therecess 121 is sealed tight. - The pushing
mechanism 13, as shown inFIG. 7 , is provided on abottom surface 121 a of therecess 121 of thepocket 12 and is arranged at the approximate center of the inside of thatrecess 121. This pushingmechanism 13 is designed to he able to abut against thebase film 32 when thetest carrier 20 is placed inside of thepocket 12. In the present embodiment, the pushingmechanism 13 faces the die 50 as a whole through thebase film 32, but the invention is not partially limited to this. It is sufficient that the pushingmechanism 13 faces the die 50 through thebase film 32 so as to include at least all of theelectrode pads 51 on thedie 50. - This pushing
mechanism 13, as shown inFIG. 8 , comprises: arubber member 131 which abuts against the bottom surface of thebase film 32; a flatplate support member 137 which supports therubber member 131; and acoil spring 138 which is interposed between thesupport member 137 and thebottom surface 121 a of thepocket 121. Note that, instead of thecoil spring 138, a rubber or other elastic member, a motor with a ball screw mechanism, a cylinder, etc. may also be interposed between thesupport member 137 and the bottom surface of thepocket 121. Alternatively, thesupport member 137 and thecoil spring 138 may be omitted and therubber member 131 may be directly fastened to thebottom surface 121 a of thepocket 121. - The
rubber member 131 has tworubber layers first rubber layer 132 is laid on thesupport member 137 and, for example, is composed of silicone rubber with a Shore A hardness of 50 degrees. On the other hand, thesecond rubber layer 133 is laid on thefirst rubber layer 132 and, for example, is composed of silicone rubber with a Shore A hardness of 5 degrees. - That is, in the present embodiment, the
second rubber layer 133 has a Young's modulus which is relatively smaller than the Young's modulus of thefirst rubber layer 132. Note that, the elastic materials which form the first and the second rubber layers 132, 133 are not particularly limited to this. It is sufficient that thesecond rubber layer 133 be softer than thefirst rubber layer 132. Further, if the layer becomes softer with distance to the test carrier 20 (in proportion to being closer to the test carrier), the number of rubber layers which form therubber member 131 is not particularly limited. The first elastic layer 152 in the present embodiment is equivalent to one example of the first elastic member in the present invention, while the second elastic member 153 in the present embodiment is equivalent to one example of the second elastic member in the present invention. - The
second rubber layer 133 has atop surface 133 a which contacts the bottom surface of thatbase film 32 when the pushingmechanism 13 pushes thebase film 32 of thetest carrier 20. Thistop surface 133 a, as shown inFIG. 8 , has a projecting shape which becomes successively higher with distance to the center of thattop surface 133 a (in proportion to being closer to the center). For this reason, when the pushingmechanism 13 contacts thebase film 32, thesecond rubber layer 133 as a whole can be made to evenly contact thebase film 32. - Note that, the configuration of the pushing mechanism is not particularly limited. For example, a pushing mechanism such as shown in
FIG. 9 orFIG. 10 can also be used. - The
rubber member 134 of the pushing mechanism 13B which is shown inFIG. 9 is configured from a single rubber layer which becomes gradually more flexible with distance from the support member 137 (in proportion to being further upward from the support member). In this example as well, thetop surface 134 a of therubber member 134 has a projecting shape which becomes gradually higher with distance to the center of thattop surface 134 a (in proportion to being closer to the center). - On the other hand, the pushing
mechanism 13C which is shown inFIG. 10 comprises, instead of therubber member 131, abag member 135 which is provided on thesupport member 137. Thisbag member 135 is, for example, composed of silicone rubber or other resin material which is flexible and has elasticity. Theinternal space 135 a holds a gas orliquid fluid 136 inside of it. - As a specific example of a fluid 136, for example, silicone grease or air etc. can be mentioned. Note that, this
fluid 136 may be filled completely in theinternal space 135 a of thebag member 135, but an amount offluid 136 less than complete may also be filled in theinternal space 135 a. - The above explained pushing
mechanisms 15, 15B, or 15C is equivalent to one example of the first pusher in the present invention. - Returning to
FIG. 7 , thepocket 12 is mounted on the board 14. At the bottom surface of thepocket 12, asuction port 124 is opened. Thissuction port 124 is connected to a vacuum pump 17 through acommunication path 141 which is formed at the inside of the board 14. - Further, for example pogo pins or
other contactors 125 are arranged inside of therecess 121 so as to correspond to theexternal terminals 312 of thetest carrier 20. Thecontactors 125 are electrically connected throughinterconnect patterns 142, which are formed inside of the board 14, to a test circuit (tester chip) 15 which is mounted on the back surface of the board 14. Note that, thetest circuit 15 may also be mounted on the top surface of board 14. In this case, thetest circuit 15 is arranged at a side of thepocket 12. - The
tester circuit 15 in the present embodiment is a chip which has the function of testing the electronic circuits which are built in thedie 50, that is, a one-chip tester which is provided with the functions of a conventional tester. Note that, the one-chip type oftester circuit 15 is just one example. For example, it is also possible to use a MCM (Multi-Chip Module) etc. to form the tester circuit or use a conventional tester instead of atester circuit 15, The one-chip type of test circuit, MCM test circuit, or conventional tester in the present embodiment is equivalent to examples of the test circuit in the present invention. - The
temperature regulating head 16, as shown inFIG. 7 , has ablock 161 which has anabutting surface 162 which abuts against thecover film 42 of thecover member 40 of thetest carrier 20. Theblock 161 has atemperature sensor 163 and aheater 164 embedded in it. Aflow path 165 through which a coolant can flow is formed in theblock 161. Thisflow path 165 is connected to a not shown chiller. - The
block 161 of thistemperature regulating head 16 can approach/move away from thetest carrier 20 placed in thepocket 12 by a not particularly shown motor with a ball screw mechanism, cylinder, etc. In the state where the abuttingface 162 of theblock 161 of thistemperature regulating head 16 contacts thecover film 42 of thetest carrier 20, thetemperature sensor 163 measures the temperature of the die 50 during the test and the measurement results are used as the basis to control the temperature of the die 50 by theheater 164 and the coolant inside theflow path 165. Note that, the temperature regulating head 14 in embodiment is equivalent to one example of the second pusher in the present invention. - In the present embodiment, when a robot arm or pick-and-place apparatus or other handling apparatus (not shown) is used to place the
test carrier 20 in apocket 12, thebase member 30 of thattest carrier 20 and theseal member 132 of thepocket 12 are used to seal therecess 121, In this state, when operating the vacuum pump 17 to reduce the pressure inside of therecess 121, thetest carrier 20 is pulled toward the inside of thepocket 12 whereby thecontactor 125 and theexternal terminals 312 contact each other. - Further, when the
temperature regulating head 16 approaches and abuts againsttest carrier 20, theheater 164 and the coolant which flows through theflow path 165 are used to control the temperature of thedie 50. At the same time as this, therubber member 131 of the pushingmechanism 13 contacts and pushes against the bottom surface of thebase film 32 of thetest carrier 20. - In this pushing action of the
rubber member 131, as shown inFIG. 11 , first, the softsecond rubber layer 133 deforms to follow theportion 32 b surrounding thebump 324 in the base film 32 (below, simply referred to as the “bump-surroundingportion 32 b”) and pushes and extends the bump-surroundingportion 32 b of thebase film 32 around thebumps 324 Note that, the bump-surroundingportion 32 b in the present embodiment is equivalent to “the portion of the first member surrounding the internal terminal” in the present invention. - At this time, the
top surface 133 a of thesecond rubber layer 133 has a projecting shape which becomes gradually higher with distance to the center, so thesecond rubber layer 133 as a whole can be made to evenly contact thebase film 32. - Further, when the
second rubber layer 133 deforms and the bump-surroundingportion 32 b is given sufficient tension, thefirst rubber layer 132 harder than thesecond rubber layer 133 pushes theportion 32 a where thebumps 324 are formed in the base film 32 (below, simply referred to as the “bump-formingportion 32 a”) toward theelectrode pads 51 of the die 50 whereby thebumps 324 and theelectrode pads 51 contact each other. In this state, thetest circuit 15 sends and receives test signals through thetest carrier 20 with the die 50 so as to test the electronic circuit which is built into thedie 50, Note that, the bump-formingportion 32 a in the present embodiment is equivalent to the “the portion of the first member where the internal terminal is formed” in the present invention. - Note that, as shown in
FIG. 12 , instead of the vacuum pump 17, the pushinghead 18 may also be used to directly push therigid board 51 of the cover member 4 of thetest carrier 20 from above so as to make thecontactors 125 contact theexternal terminals 312 of thetest carrier 20. This pushinghead 18 can, for example, approach/move away from thetest carrier 20 by a not particularly shown motor with a ball screw mechanism, cylinder, etc. Note that, the vacuum pump 17 or the pushinghead 18 in the present embodiment is equivalent to one example of the contacting device in the present invention. - As explained above, in the present embodiment, a pushing
mechanism 13 which has tworubber layers portions 32 a of thebase film 32, but also the bump-surroundingportions 32 b. For this reason, it is possible to push and extend thebase film 32 and eliminate waviness of thebase film 32 while making thebumps 324 of thetest carrier 20 contact theelectrode pads 51 of the die 50, so it is possible to suppress poor contact of thebumps 324 andelectrode pads 51. - Further, in the present embodiment, the
first rubber layer 132 and thesecond rubber layer 133 can be used to absorb warping of thedie 50 and variation in height of thebumps 324. - Note that, the above explained embodiment was described to facilitate understanding of the present invention and was not described for limiting the present invention. Therefore, the elements which were disclosed in the embodiment include all design changes and equivalents falling under the technical scope of the present invention.
- For example, a configuration reversing the positional relationship between the pushing
mechanism 13 and thetemperature regulating head 16 also falls under the technical scope of the present invention. That is, inFIG. 7 , the pushingmechanism 13 may also be made to approach thetest carrier 20 from above and provide atemperature regulating head 16 inside thepocket 12 of thesocket 11. -
