【発明の属する技術分野】
本発明は、携帯電話機などの電子機器に装備される電子部品としての積層モジュールに関するものである。
【0002】
【従来の技術】
従来、携帯電話機などの小型の電子機器においては、複数の回路素子を1チップの積層モジュールに集積化して、該積層モジュールを回路基板上に実装することが行なわれている。
積層モジュールにおいては、図7及び図8に示す如く、複数のセラミックス層が積層されて積層基板(8)が構成され、該積層基板(8)中に、コンデンサやインダクターを構成すべき内蔵回路パターン(32)が作り込まれている。又、積層基板(8)の表面には、基板中に作り込むことが出来ないチップ部品(4)(41)を実装し、基板表面には、前記チップ部品(4)(41)を覆う金属製カバー(9)が取り付けられる(非特許文献1参照)。

【発明が解決しようとする課題】
ところで、近年における携帯電話機などの電子機器の小型化に伴って、積層モジュールに対する小型化の要求が益々高まっている。一方、積層モジュールに要求される機能は益々拡大しており、これに伴って、内蔵すべき回路パターンや実装すべきチップ部品の数が増加しており、回路パターンやチップ部品の集積度を上げる必要が生じている。
【0005】
しかしながら、従来の積層モジュールにおいては、積層基板(8)上の複数のチップ部品(4)(41)を金属製カバー(9)によって覆う構造が採用されているため、金属製カバー(9)の内部には、チップ部品(4)(41)の周囲に拡がる大きな空間が形成されることとなり、これによってモジュール全体が大型化する問題があった。
又、外力の作用によって金属製カバー(9)が変形すると、その歪みが積層基板(8)の内蔵回路パターン(32)に影響を及ぼし、特に高周波数域においては回路動作が不安定となる問題があった。
【0006】
そこで本発明の目的は、小型化が可能であり、然も安定した回路動作を実現することが出来る積層モジュールを提供することである。
【0007】
【課題を解決する為の手段】
本発明に係る積層モジュールは、積層構造を有して回路パターン(3)が内蔵された第1積層基板(1)と、積層構造を有して回路パターン(31)が内蔵された第2積層基板(2)とを具え、両積層基板(1)(2)は、接合パターン(7)(71)を介して互いに接合されると共に、互いに電気的に接続されている。
両積層基板(1)(2)の対向面間には、少なくとも1つのチップ部品が介在し、少なくとも何れか一方の積層基板の対向面に、該チップ部品が嵌まる凹部が形成され、該チップ部品は、該凹部に嵌合した状態で両積層基板(1)(2)によって挟持されている。
両積層基板(1)(2)には、少なくとも前記チップ部品を挟んで両側に、グランド層が形成されている。又、何れか一方の積層基板には、前記凹部の底面に、チップ部品の端子部と接続されるパッドが形成されている。
【0008】
上記本発明の積層モジュールにおいては、従来は金属製カバーによって覆われていた複数のチップ部品が、第1積層基板(1)と第2積層基板(2)の間に挟持されて、両基板の間に埋設されているので、従来の金属製カバーの装着は不要である。
従って、チップ部品の周囲に無駄な空間は存在せず、この結果、モジュール全体の小型化が可能である。然も、両積層基板(1)(2)中に多くの内蔵回路パターンを作り込むことが出来るので、積層モジュールの多機能化が可能である。
又、第1積層基板(1)と第2積層基板(2)とが互いに一体化された構造を有しているので、モジュール全体としての剛性が高く、外力の作用によっても容易に変形しないので、高周波数域においても安定した回路動作が実現される。
【0009】
【発明の効果】
本発明に係る積層モジュールによれば、小型化が可能であると共に、安定した回路動作を実現することが出来る。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態につき、図面に沿って具体的に説明する。
図1及び図2に示す本発明の積層モジュールは、複数のセラミックス層からなる第1積層基板(1)と、複数のセラミックス層からなる第2積層基板(2)とを接合して構成され、両積層基板(1)(2)の間に、複数のチップ部品(4)(41)が挟持されている。
第1積層基板(1)及び第2積層基板(2)には、コンデンサやインダクター等を構成すべき内蔵回路パターン(3)(31)が作り込まれている。又、第1積層基板(1)及び第2積層基板(2)には、最も外側の中間層に、基板全域若しくは略全域に拡がる内蔵グランド層(5)(51)が形成されている。
尚、第2積層基板(2)の内蔵グランド層(51)は、基板全域に拡がっているのに対し、第1積層基板(1)の内蔵グランド層(5)は、図3(a)(b)に示す如く、信号入力端子(15)(16)及び信号出力端子(17)(18)を除く基板領域に拡がっている。
【0011】
図1及び図2に示す如く、第2積層基板(2)と対向する第1積層基板(1)の内面には、複数のチップ部品(4)(41)の下半部がそれぞれ嵌まる複数の凹部(11)(12)が形成されており、該凹部(11)(12)の底面には、チップ部品(4)(41)の端子部を半田付けするためのパッド(6)(61)(61)が形成されている。
一方、第1積層基板(1)と対向する第2積層基板(2)の内面には、複数のチップ部品(4)(42)の上半部がそれぞれ嵌まる複数の凹部(21)(22)が形成されている。
【0012】
又、第1積層基板(1)の内面には、その外周部に接合パターン(7)が形成されると共に、その内側に、内蔵回路パターン(3)と繋がる信号端子(72)が形成されている。第2積層基板(2)の内面には、第1積層基板(1)の接合パターン(7)と対応する位置に、接合パターン(71)形成されると共に、第1積層基板(1)の信号端子(72)と対応する位置に、内蔵回路パターン(31)と繋がる信号端子(73)が形成されている。
【0013】
第1積層基板(1)に複数のチップ部品(4)(41)を実装することによって、これらのチップ部品(4)(41)は内蔵回路パターン(3)と繋がることになる。
そして、第1積層基板(1)と第2積層基板(2)を図1の如く互いに対向せしめ、接合パターン(7)(71)どうし並びに信号端子(72)(73)どうしを半田によって接合することにより、積層モジュールが組み立てられる。この結果、複数のチップ部品(4)(41)は、両積層基板(1)(2)の凹部(11)(12)(21)(22)に収容された状態で、両積層基板(1)(2)の間に挟持される。
【0014】
又、第1積層基板(1)の内蔵回路パターン(3)と第2積層基板(2)の内蔵回路パターン(31)とが互いに接続され、両内蔵回路パターン(3)(31)が互いに関連して動作することになる。
この際、チップ部品(4)(41)及び内蔵回路パターン(3)(31)は、その両側に配置された内蔵グランド層(5)(51)によって包囲されているので、外部ノイズの影響を受けることはない。
【0015】
図4に示す本発明の積層モジュールにおいては、第1積層基板(1)の内面に、複数の接合パターン(7)が形成されると共に、複数のチップ部品(42)(43)を実装するためのパッド(62)(62)(63)(63)が形成されている。又、第1積層基板(1)には、最も外側の中間層に、基板全域若しくは略全域に拡がる内蔵グランド層(52)が形成されている。
一方、第2積層基板(2)の内面には、チップ部品(42)(43)の略全体が嵌まる凹部(23)(24)が形成されている。又、第2積層基板(2)には、その表面を覆って、表面グランド層(53)が形成されている。
【0016】
上記積層モジュールにおいては、複数のチップ部品(42)(43)は、第2積層基板(2)の凹部(23)(24)に収容された状態で、両積層基板(1)(2)の間に挟持される。
チップ部品(42)(43)及び内蔵回路パターン(3)は、その両側に配置された内蔵グランド層(52)及び表面グランド層(53)によって包囲されているので、外部ノイズの影響を受けることはない。
【0017】
図5に示す積層モジュールは、図3に示す積層モジュールと基本的に同じ構造を有しているが、図4に示す如く、第2積層基板(2)の表面を覆う表面グランド層(53)に、品番やメーカ名を表わす文字列(54)が透かし彫りの状態で形成されている。該文字列(54)は、表面グランド層(53)の形成工程にてマスクパターンで同時に形成することが出来る。
【0018】
更に図6に示す積層モジュールは、図3に示す積層モジュールと同様の構造を有しているが、図5に示す如く、第2積層基板(2)の表面及び側面を覆って、表面グランド層(55)が形成され、該表面グランド層(55)には、品番やメーカ名を表わす文字列(54)が透かし彫りの状態で形成されている。
【0019】
上記の何れの積層モジュールにおいても、従来は金属製カバーによって覆われていた複数のチップ部品が、第1積層基板(1)と第2積層基板(2)の間に挟持されて、両基板の間に埋設されているので、従来の金属製カバーの装着は不要である。従って、チップ部品の周囲に無駄な空間は存在せず、この結果、モジュール全体の小型化が可能である。
【0020】
又、両積層基板(1)(2)中に多くの内蔵回路パターンを作り込むことが出来るので、積層モジュールの多機能化が可能である。
又、複数のチップ部品は両積層基板(1)(2)の間に埋設されているので、安定した動作が実現出来、更なる高集積度化に対応可能である。
更に、第1積層基板(1)と第2積層基板(2)とが互いに一体化された構造を有しているので、モジュール全体としての剛性が高く、外力の作用によっても容易に変形しないので、高周波数域においても安定した回路動作が実現される。
【0021】
更に又、図1及び図2に示す積層モジュールにおいては、複数のチップ部品(4)(41)が第1積層基板(1)の凹部(11)(12)と第2積層基板(2)の凹部(21)(22)の両方に嵌合するので、両積層基板(1)(2)の重ね合わせの位置決めを精度良く行なうことが出来る。
【0022】
尚、本発明の各部構成は上記実施の形態に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能である。例えば、図4〜図6に示す積層モジュールにおいては、図1及び図2に示す積層モジュールと同様に、第1積層基板(1)にもチップ部品(42)(43)が嵌まる凹部を形成して、チップ部品(42)(43)を両積層基板の凹部に嵌合させる構造とすることも可能である。

[Problems to be solved by the invention]
By the way, with the miniaturization of electronic devices such as mobile phones in recent years, the demand for miniaturization of stacked modules has been increasing more and more. On the other hand, the functions required for the laminated module are expanding more and more, and accordingly, the number of circuit patterns to be incorporated and the number of chip components to be mounted are increasing, and the integration degree of the circuit patterns and chip components is increased. The need has arisen.
[0005]
However, the conventional laminated module employs a structure in which the plurality of chip components (4) and (41) on the laminated substrate (8) are covered by the metal cover (9). Inside, a large space extending around the chip components (4) and (41) is formed, which causes a problem that the entire module becomes large.
Further, when the metal cover (9) is deformed by the action of an external force, the distortion affects the built-in circuit pattern (32) of the laminated substrate (8), and the circuit operation becomes unstable particularly in a high frequency range. was there.

[Means for solving the problem]
The laminated module according to the present invention includes a first laminated substrate (1) having a laminated structure and a built-in circuit pattern (3) and a second laminated substrate having a laminated structure and a built-in circuit pattern (31). A substrate (2) is provided, and both laminated substrates (1) and (2) are joined to each other via joining patterns (7) and (71) and are electrically connected to each other.
At least one chip component is interposed between the opposing surfaces of both laminated substrates (1) and (2), and a concave portion in which the chip component is fitted is formed on at least one of the opposing surfaces of the laminated substrate. The component is sandwiched between the two laminated substrates (1) and (2) in a state fitted in the concave portion.
Ground layers are formed on both laminated substrates (1) and (2) at least on both sides of the chip component. Further, on one of the laminated substrates, a pad connected to a terminal part of the chip component is formed on the bottom surface of the concave portion.
[0008]
In the laminated module of the present invention, a plurality of chip components conventionally covered by a metal cover are sandwiched between the first laminated substrate (1) and the second laminated substrate (2), and the Since it is buried in between, there is no need to attach a conventional metal cover.
Therefore, there is no useless space around the chip component, and as a result, the entire module can be reduced in size. Needless to say, a large number of built-in circuit patterns can be formed in both the laminated substrates (1) and (2), so that the laminated module can be multifunctional.
Further, since the first laminated substrate (1) and the second laminated substrate (2) have a structure integrated with each other, the rigidity of the module as a whole is high and the module is not easily deformed by the action of external force. Thus, a stable circuit operation is realized even in a high frequency range.
