Description

本発明は、異なる基板上に設けられた回路間や、機器間の電気的接続を行うためのマイクロコネクタに関する。   The present invention relates to a microconnector for electrical connection between circuits provided on different substrates or between devices.

従来、異なる基板上に設けられた回路間や、機器間の電気的接続を行うためのコネクタは、ばねとなる金属材料を機械的に切断して、切断後の金属材料に曲げ加工を行う方法により作成されている。しかしながら、金属材料に機械的な切断加工や曲げ加工を行ってコネクタを作成する方法では、コネクタの微細化に限界があり、携帯機器などの更なる小型化やICレベルでの配線接続に対応可能な微細なコネクタを製造することが困難であるといった問題があった。   Conventionally, a connector for electrical connection between circuits or devices provided on different substrates is a method of mechanically cutting a metal material to be a spring and bending the cut metal material It is created by. However, the method of creating connectors by mechanically cutting and bending metal materials has limitations in miniaturizing connectors, and can be used for further miniaturization of portable devices and wiring connections at the IC level. There is a problem that it is difficult to manufacture a fine connector.

そこで、コネクタを含むマイクロ構造体の分野において、従来の半導体デバイス製造に用いられる工程(半導体プロセス)とめっき工程とを用いて、マイクロ構造体の微細化を図るようにしたものが知られている(例えば、特許文献1及び2参照)。また、コネクタの分野において、従来の半導体デバイス製造に用いられる工程とめっき工程とを用いて、嵌合操作が容易で、精度のよい嵌合を行うことが可能な電気コネクタが開示されている(例えば、特許文献3参照)。   Therefore, in the field of microstructures including connectors, there is known a technique for miniaturizing a microstructure using a process (semiconductor process) and a plating process used in conventional semiconductor device manufacturing. (For example, refer to Patent Documents 1 and 2). Further, in the field of connectors, an electrical connector is disclosed that is easy to perform a fitting operation and can be accurately fitted using a process and a plating process used in conventional semiconductor device manufacturing ( For example, see Patent Document 3).

上述した特許文献3に記載の電気コネクタでは、コネクタの雄端子と雌端子とを嵌合させることは容易であるかもしれない。また、特許文献3の第2の実施形態の発明(図6及び7に示される発明)によれば、雄端子と雌端子との嵌合を外れにくくすることも可能であるかもしれない。しかしながら、一旦、コネクタの雄端子と雌端子との嵌合を解除した後に、再度雄端子と雌端子とを嵌合させた場合には、雄端子と雌端子との接続が外れやすくなってしまうという問題があった。また、特許文献3に記載の電気コネクタでは、積層された基板間を電気的に接続することができないという問題があった。なお、上記特許文献1及び2には、コネクタの雄端子と雌端子との接続に関する開示はない。   In the electrical connector described in Patent Document 3 described above, it may be easy to fit the male terminal and female terminal of the connector. Further, according to the invention of the second embodiment of Patent Document 3 (the invention shown in FIGS. 6 and 7), it may be possible to make it difficult to disengage the male terminal and the female terminal. However, once the male terminal and the female terminal of the connector are released from the fitting and then the male terminal and the female terminal are fitted again, the male terminal and the female terminal are easily disconnected. There was a problem. Further, the electrical connector described in Patent Document 3 has a problem that the stacked substrates cannot be electrically connected. Patent Documents 1 and 2 do not disclose the connection between the male terminal and female terminal of the connector.

By adopting such a configuration, even when the male terminal and the female terminal are repeatedly attached and detached (fitting and detaching the projection on the male terminal side and the frame on the female terminal side), the male terminal and the female terminal Can be easily attached and detached. In addition, since the frame portion on the female terminal side has a spring structure, the connection between the male terminal and the female terminal (fitting between the projection on the male terminal side and the frame portion on the female terminal side) is difficult to be disconnected. be able to.

Furthermore, since the projection on the male terminal side and the frame on the female terminal side are fitted in the vertical direction, the substrates stacked in the vertical direction can be electrically connected. Therefore, further downsizing of the portable device and the like can be achieved.

以下、本発明の一実施形態に係るマイクロコネクタについて、図面を参照して説明する。図1(a)(b)は、それぞれ本実施形態のマイクロコネクタの雄端子と雌端子との平面図である。図2は、支持基板に形成された上記雄端子と雌端子とを側面側から見た図である。図1(a)は、図2中の支持基板5の下面側から見た雄端子の平面図であり、図1(b)は、図2中の支持基板6の上面側から見た雌端子の平面図である。これらの図に示されるように、マイクロコネクタ1は、セラミックやガラスエポキシ材等の支持基板(請求項における基板)6上に、レジストのパターニング工程を含む半導体プロセスとめっき工程とを用いて作成された雄端子2と雌端子3とを備えている。雄端子2は、支持基板5上に形成されたベース部2aと、支持基板5と垂直な方向に突出した球状突起部2b(請求項における突起部)と、球状突起部2bを支持する支持部2cとを有している。雌端子3は、支持基板6上に形成されたベース部3a、3bと、ばね構造を有する枠部4とを備えている。枠部4は、立ち上がり部4a、4bと、立ち上がり部4a、4bから水平方向に延びる平行部4c、4dと、平行部4c、4dから延設された半楕円形状(楕円の半分の形状)の枠部材4e、4fと、枠部材4e、4fから水平方向に延びる平行部4g、4hと、平行部4g、4hから延設された立ち上がり部4i、4jとから構成される。   Hereinafter, a microconnector according to an embodiment of the present invention will be described with reference to the drawings. FIGS. 1A and 1B are plan views of a male terminal and a female terminal of the microconnector of the present embodiment, respectively. FIG. 2 is a view of the male terminal and the female terminal formed on the support substrate as viewed from the side. 1A is a plan view of a male terminal viewed from the lower surface side of the support substrate 5 in FIG. 2, and FIG. 1B is a female terminal viewed from the upper surface side of the support substrate 6 in FIG. FIG. As shown in these drawings, the microconnector 1 is formed on a support substrate (substrate in claims) 6 such as ceramic or glass epoxy material by using a semiconductor process including a resist patterning step and a plating step. A male terminal 2 and a female terminal 3 are provided. The male terminal 2 includes a base 2a formed on the support substrate 5, a spherical protrusion 2b (protrusion in the claims) protruding in a direction perpendicular to the support substrate 5, and a support that supports the spherical protrusion 2b. 2c. The female terminal 3 includes base portions 3a and 3b formed on the support substrate 6 and a frame portion 4 having a spring structure. The frame part 4 has rising parts 4a and 4b, parallel parts 4c and 4d extending in the horizontal direction from the rising parts 4a and 4b, and a semi-elliptical shape (half of an ellipse) extending from the parallel parts 4c and 4d. The frame members 4e and 4f, parallel portions 4g and 4h extending in the horizontal direction from the frame members 4e and 4f, and rising portions 4i and 4j extending from the parallel portions 4g and 4h are configured.

上記の枠部4は、応力を受けていない状態では、球状突起部2bの挿入を防ぎ得る形状であり、応力を受けると、球状突起部2bの挿入可能な形状に変形可能である。具体的には、枠部4の枠部材4e、4fから構成される楕円形状の枠4k(図1(b)中の破線で囲んだ部分)は、球状突起部2bが嵌入される前は、図1(b)で上下方向の幅Wが、球状突起部2bの直径よりも小さくなっている。これに対して、枠4k内に球状突起部2bが嵌入されると(球状突起部2bにより押圧されると)、枠4kは、ばね構造を有しているため、図1(b)で上下方向に押し広げられて、その幅Wが球状突起部2bの直径よりも大きくなる。そして、球状突起部2bの枠4kへの嵌入が完了すると、枠4kは、その幅Wが再び球状突起部2bの直径よりも小さくなる。これにより、雄端子2側の球状突起部2bと雌端子3側の枠部4(枠4k)とが、垂直方向に嵌合される。なお、枠部4に、立ち上がり部4a、4b、4i、4jを設けた理由は、雌端子3の枠4kと支持基板6との間に、球状突起部2bを収納するスペースを設けるためである。   The frame 4 has a shape that can prevent the spherical protrusion 2b from being inserted in a state where no stress is received, and can be deformed into a shape in which the spherical protrusion 2b can be inserted when stress is received. Specifically, an elliptical frame 4k (a portion surrounded by a broken line in FIG. 1B) composed of the frame members 4e and 4f of the frame part 4 is inserted before the spherical protrusion 2b is inserted. In FIG. 1B, the vertical width W is smaller than the diameter of the spherical protrusion 2b. On the other hand, when the spherical protrusion 2b is inserted into the frame 4k (when pressed by the spherical protrusion 2b), the frame 4k has a spring structure, so that the upper and lower sides in FIG. The width W becomes larger than the diameter of the spherical protrusion 2b. When the insertion of the spherical protrusion 2b into the frame 4k is completed, the width 4 of the frame 4k becomes smaller than the diameter of the spherical protrusion 2b again. Thereby, the spherical protrusion 2b on the male terminal 2 side and the frame part 4 (frame 4k) on the female terminal 3 side are fitted in the vertical direction. The reason why the rising portions 4a, 4b, 4i, and 4j are provided in the frame portion 4 is to provide a space for housing the spherical protrusion portion 2b between the frame 4k of the female terminal 3 and the support substrate 6. .

上記支持基板5に載置されたIC7、及び支持基板6に載置されたIC8は、ワイヤ9又は10を用いて、ワイヤボンディングで、雄端子2又は雌端子3と電気的に接続されている。   The IC 7 placed on the support substrate 5 and the IC 8 placed on the support substrate 6 are electrically connected to the male terminal 2 or the female terminal 3 by wire bonding using the wire 9 or 10. .

また、上記の雄端子2と雌端子3とは、いずれも異なる種類の金属を多層化して形成されている。これらの金属の組み合わせとしては、例えば、図2に示される組み合わせが考えられる。すなわち、雄端子2については、支持基板5に接する金属層20aを支持基板5との密着性のよい金属で構成し、この金属層20aと接する金属層20bを接触抵抗が低い金属で構成し、この金属層20bと接する金属層20c(支持部2c)を合成を保持し得る金属で構成する。また、雌端子3については、支持基板6に接する金属層30aを支持基板6との密着性のよい金属で構成し、それ以外の部分の金属層30bを接触抵抗が低い金属で構成する。このように、支持基板5、6に接する金属層20a、30aを支持基板5、6との密着性のよい金属で構成したことにより、雄端子2及び雌端子3を支持基板5、6に接合した状態を保持することができる。また、金属層20b、30bを接触抵抗が低い金属で構成したことにより、雄端子2及び雌端子3に必要とされる導電性を確保することができる。さらにまた、金属層20cを合成を保持し得る金属で構成したことにより、支持部2cに強度(剛性)を付与することができるので、支持部2cが球状突起部2bを確実に支持することができるようになる。   In addition, the male terminal 2 and the female terminal 3 are formed by multilayering different types of metals. As a combination of these metals, for example, the combination shown in FIG. 2 can be considered. That is, for the male terminal 2, the metal layer 20a in contact with the support substrate 5 is made of a metal having good adhesion to the support substrate 5, and the metal layer 20b in contact with the metal layer 20a is made of a metal having low contact resistance. The metal layer 20c (support portion 2c) in contact with the metal layer 20b is made of a metal capable of maintaining synthesis. As for the female terminal 3, the metal layer 30a in contact with the support substrate 6 is made of a metal having good adhesion to the support substrate 6, and the other metal layer 30b is made of a metal having low contact resistance. As described above, the metal layers 20a and 30a in contact with the support substrates 5 and 6 are made of a metal having good adhesion to the support substrates 5 and 6, so that the male terminal 2 and the female terminal 3 are joined to the support substrates 5 and 6. Can be maintained. Moreover, the electroconductivity required for the male terminal 2 and the female terminal 3 is securable by comprising the metal layers 20b and 30b with the metal with low contact resistance. Furthermore, since the metal layer 20c is made of a metal capable of maintaining synthesis, strength (rigidity) can be imparted to the support portion 2c, so that the support portion 2c can reliably support the spherical protrusion 2b. become able to.

上記の支持基板6との密着性のよい金属の例としては、Ni(ニッケル)やCr(クロム)が挙げられる。また、接触抵抗が低い金属の例としては、Cu(銅)やAu(金)が挙げられる。また、合成を保持し得る金属の例としては、Fe(鉄)が挙げられる。   Examples of the metal having good adhesion to the support substrate 6 include Ni (nickel) and Cr (chromium). Examples of metals with low contact resistance include Cu (copper) and Au (gold). Moreover, Fe (iron) is mentioned as an example of the metal which can hold | maintain a synthesis | combination.

次に、図3を参照して、上記の雄端子2の製造方法の一例について説明する。図3(a)(b)(c)(d)(e)(f)(g)(h)(i)の各図において、左側の図と右側の図とは、各製造段階における支持基板5上の積層状態を示す側断面図と上面図である。   Next, an example of a method for manufacturing the male terminal 2 will be described with reference to FIG. 3 (a) (b) (c) (d) (e) (f) (g) (h) (i), the left and right views are the support substrate in each manufacturing stage. FIG. 5 is a side sectional view and a top view showing a stacked state on the board 5.

まず、図3(a)に示されるセラミックやガラスエポキシ材等の支持基板5上に、図3(b)に示されるように、スパッタ等の方法で、Ni系の金属から構成されるシード層12(図2中の金属層20a)を成膜する。そして、このシード層12上の全面に電極11(図2中の金属層20a)の元になる金属を塗布する。次に、この電極11(の元になる金属)の全面にレジストを塗布して、一連のパターニング工程を行うことにより、図3(b)の右図に示されるような電極11の形にレジスト層を残す。そして、電極11(の元になる金属)における、レジスト層が取り除かれた部分をエッチングにより除去して、電極11を図3(b)の右図に示されるような形にした後に、レジスト層を除去剤等により除去する。この電極11は、めっき工程において陰極として機能する。   First, on a support substrate 5 such as a ceramic or glass epoxy material shown in FIG. 3 (a), as shown in FIG. 3 (b), a seed layer made of a Ni-based metal by a method such as sputtering. 12 (metal layer 20a in FIG. 2) is formed. And the metal which becomes the origin of the electrode 11 (metal layer 20a in FIG. 2) is apply | coated to the whole surface on this seed layer 12. FIG. Next, a resist is applied to the entire surface of the electrode 11 (the metal from which the electrode 11 is formed), and a series of patterning steps are performed to form the resist 11 in the shape of the electrode 11 as shown in the right diagram of FIG. Leave a layer. Then, the portion of the electrode 11 (the metal from which the resist layer has been removed) is removed by etching to form the electrode 11 as shown in the right diagram of FIG. Is removed with a remover or the like. The electrode 11 functions as a cathode in the plating process.

次に、レジストの塗布、乾燥ベーキング、マスク合わせ、及び露光の工程から構成される、レジストのパターニング工程を行って、図3(c)に示されるようなホール16を有する圧膜レジスト層13を形成する。このレジスト層13の厚さは、30〜50μmである。そして、図3(c)に示される、電極11上における圧膜レジスト層13から露出した部分(ホール16の部分)に電気めっき(めっき工程)を行って、図3(d)に示されるように、Feから構成される、厚さ30〜50μmのめっき層14を形成する。このめっき層14は、図2中の金属層20c(支持部2c)に相当する。次に、図3(e)に示されるように、圧膜レジスト層13をガスとの化学反応を利用して削る(アッシングする)。   Next, a resist patterning process composed of resist application, dry baking, mask alignment, and exposure processes is performed to form a pressure film resist layer 13 having holes 16 as shown in FIG. Form. The thickness of the resist layer 13 is 30 to 50 μm. Then, electroplating (plating process) is performed on a portion (hole 16) exposed from the pressure film resist layer 13 on the electrode 11 shown in FIG. 3C, as shown in FIG. 3D. Then, a plating layer 14 having a thickness of 30 to 50 μm made of Fe is formed. The plating layer 14 corresponds to the metal layer 20c (support portion 2c) in FIG. Next, as shown in FIG. 3E, the pressure film resist layer 13 is shaved (ashed) using a chemical reaction with a gas.

次に、圧膜レジスト層13上において、レジストの塗布、乾燥ベーキング、マスク合わせ、及び露光の工程から構成される、レジストのパターニング工程を行って、図3(f)に示されるようなホール17を有するレジスト層15を形成する。このレジスト層15の厚さは、10〜20μmである。そして、図3(f)の右側の図に示されるホール17の部分に電気めっき(めっき工程)を行って、図3(g)に示されるように、Au系の合金から構成されるめっき層18を形成する。このめっき層18は、図2中の球状突起部2bに相当する。次に、図3(h)に示されるように、レジスト層15と圧膜レジスト層13を除去剤等により除去する。そして、最後に、レジスト層除去により表面に現れた(電極11の真下以外の部分の)シード層12を、図3(i)に示されるように、エッチング又はイオンミリング(アルゴンイオン等のイオンビームを用いた研磨処理)により除去する。これにより、雄端子2の製造が完了する。   Next, on the pressure film resist layer 13, a resist patterning process including resist coating, dry baking, mask alignment, and exposure processes is performed to form holes 17 as shown in FIG. A resist layer 15 is formed. The resist layer 15 has a thickness of 10 to 20 μm.
