Description

高周波回路基板ならびにこれを用いた高周波半導体パッケージおよび高周波半導体装置High frequency circuit board, high frequency semiconductor package and high frequency semiconductor device using the same
 本発明は、高周波信号が伝送される信号線路が形成された高周波回路基板に関し、特に信号線路同士の接続部に特徴を有する高周波回路基板、これを用いた高周波半導体パッケージおよび高周波半導体装置に関する。 The present invention relates to a high-frequency circuit board on which a signal line for transmitting a high-frequency signal is formed, and more particularly to a high-frequency circuit board characterized by a connection portion between signal lines, a high-frequency semiconductor package and a high-frequency semiconductor device using the same.
 マイクロ波帯やミリ波帯等の高周波信号線路同士を接続する際は、2本の信号線路同士を一直線に配置して接続するのが好ましい。しかしながら、実際は、信号線路同士を一直線上に精確に並べて接続するのは容易なことではない。 When connecting high-frequency signal lines such as a microwave band and a millimeter wave band, it is preferable to connect the two signal lines in a straight line. However, in practice, it is not easy to connect the signal lines accurately in a straight line.
 従来、線路導体の接続端に線路導体よりも幅の広い接続パッドを設ける方法がよく用いられる(例えば、特許文献1参照)。接続パッドは、信号線路同士の位置が食い違い、精確に一直線に並んでいない信号線路同士を導通させる。 Conventionally, a method of providing a connection pad wider than the line conductor at the connection end of the line conductor is often used (see, for example, Patent Document 1). The connection pad makes the positions of the signal lines inconsistent and makes the signal lines that are not accurately aligned in a conductive state.
 図8に示すように、第1の信号線路100の端部に第1の接続パッド101が設けられ、第2の信号線路102の端部には第2の接続パッド103が設けられている。そして、第1の線路導体100と第2の線路導体102とは、ボンディングワイヤ等の接続線路104を介して接続される。 As shown in FIG. 8, a first connection pad 101 is provided at the end of the first signal line 100, and a second connection pad 103 is provided at the end of the second signal line 102. The first line conductor 100 and the second line conductor 102 are connected via a connection line 104 such as a bonding wire.
 図8に於いては、第1の信号線路100と接続線路104と第2の信号線路102とが一直線上に並ぶように配置されている。しかし、これらが一直線上に配置されなかった場合には、例えば、接続線路104が第1の信号線路101および第2の信号線路102の中心線から外れた位置に配置された場合、第1の信号線路100と第2の信号線路102とは接続線路104を介して導通が取れなくなってしまう場合がある。 In FIG. 8, the first signal line 100, the connection line 104, and the second signal line 102 are arranged in a straight line. However, when these are not arranged on a straight line, for example, when the connection line 104 is arranged at a position off the center line of the first signal line 101 and the second signal line 102, the first line There is a case where the signal line 100 and the second signal line 102 cannot be electrically connected via the connection line 104.
 ところが、第1の接続パッド101および第2の接続パッド103が第1の信号線路100および第2の信号線路102よりも広い幅で設けられているため、接続線路104の偏心が、これら第1の接続パッド101および第2の接続パッド103の幅以内であれば、第1の信号線路100と第2の信号線路102とは接続される。 However, since the first connection pad 101 and the second connection pad 103 are provided with a width wider than that of the first signal line 100 and the second signal line 102, the eccentricity of the connection line 104 is caused by the first eccentricity. The first signal line 100 and the second signal line 102 are connected to each other within the width of the connection pad 101 and the second connection pad 103.

 しかしながら、周波数が高い高周波信号を伝送する信号線路において、接続パッド101,103が配置される部分におけるインピーダンスは、高周波線路の特性インピーダンスとは異なる。それ故に、信号線路100,102の伝送特性を劣化させる原因となってしまう。 However, in a signal line that transmits a high-frequency signal having a high frequency, the impedance at a portion where the connection pads 101 and 103 are arranged is different from the characteristic impedance of the high-frequency line. Therefore, the transmission characteristics of the signal lines 100 and 102 are deteriorated.
 従って、本発明は上記従来の問題点に鑑みて完成されたものであり、その目的は、高周波線路を接続する際に、著しいインピーダンス不整合を招来せずに、線路導体の接続を容易に行なえる線路導体を有する高周波回路基板、ならびにこれを用いた高周波半導体パッケージおよび高周波半導体装置を提供することにある。 Accordingly, the present invention has been completed in view of the above-described conventional problems, and the object of the present invention is to easily connect line conductors without causing a significant impedance mismatch when connecting high-frequency lines.

The high-frequency circuit board has a connection portion in which the first line conductor and the second line conductor are connected in an overlapping manner. The connecting portion includes a plurality of wide portions having a wide line width and a narrow portion having a line width narrower than the wide portions disposed between the wide portions.
 上記高周波回路基板において、前記幅広部は、前記線路導体から幅方向に離れるに従って前記線路導体の線路方向の幅が狭くなる形状を有してもよい。 In the high-frequency circuit board, the wide portion may have a shape in which the width of the line conductor in the line direction becomes narrower as the distance from the line conductor increases.
 また上記高周波回路基板において、前記幅狭部の線幅は、前記接続端または前記接続部を除く部分の前記線路導体の線幅よりも狭いものとしてもよい。 In the high-frequency circuit board, a line width of the narrow portion may be narrower than a line width of the line conductor in a portion excluding the connection end or the connection portion.
 また上記高周波回路基板において、前記線路導体は、前記接続端または前記接続部に隣接した位置に、線幅を狭くした第2幅狭部を有してもよい。 In the high-frequency circuit board, the line conductor may have a second narrow portion with a narrow line width at a position adjacent to the connection end or the connection portion.
 本発明の一実施形態に係る高周波半導体パッケージは、高周波半導体素子が収納される容器の入出力部に、上記いずれか1つの高周波回路基板が用いられていることを特徴とする。 A high-frequency semiconductor package according to an embodiment of the present invention is characterized in that any one of the above-described high-frequency circuit boards is used for an input / output part of a container in which a high-frequency semiconductor element is stored.
 本発明の一実施形態に係る高周波半導体装置は、上記高周波半導体パッケージと、前記容器内に収納され、前記高周波回路基板の前記線路導体に接続された高周波半導体素子とを有することを特徴とする。 A high-frequency semiconductor device according to an embodiment of the present invention includes the high-frequency semiconductor package, and a high-frequency semiconductor element housed in the container and connected to the line conductor of the high-frequency circuit board.
 本発明の一実施形態に係る高周波回路基板は、接続端に、線幅が広い複数の幅広部と、複数の幅広部の間に配置された幅広部よりも線幅の狭い幅狭部とを有した線路導体を具備していることから、接続する線路導体同士の位置精度の許容範囲を保ちながら、接続端の容量成分を少なくすることができ、線路導体に著しいインピーダンス不整合を生じないものとすることができる。 A high-frequency circuit board according to an embodiment of the present invention includes, at a connection end, a plurality of wide portions having a wide line width and a narrow portion having a narrower line width than the wide portion disposed between the plurality of wide portions. Because it has the line conductors it has, it can reduce the capacitance component of the connection end while maintaining the tolerance of the positional accuracy of the line conductors to be connected, and does not cause a significant impedance mismatch in the line conductors It can be.
 また、本発明の一実施形態に係る高周波回路基板は、第1線路導体と第2線路導体とが接続された接続部は、線幅が広い複数の幅広部と、この幅広部の間に配置された幅広部よりも線幅の狭い幅狭部とを有していることから、接続部に生じる容量成分が少なく、線路導体に著しいインピーダンス不整合が生じないようにすることができる。 In the high-frequency circuit board according to one embodiment of the present invention, the connection portion where the first line conductor and the second line conductor are connected is disposed between a plurality of wide portions having a wide line width and the wide portions. Since the narrow portion having a narrower line width than the wide portion formed is provided, the capacitance component generated in the connection portion is small, and a significant impedance mismatch can be prevented from occurring in the line conductor.

 本発明の一実施形態に係る高周波回路基板について、以下に詳細に説明する。図1は高周波回路基板とこれに接続される電気回路基板との実施の形態の一例を示す分解斜視図である。 A high-frequency circuit board according to an embodiment of the present invention will be described in detail below. FIG. 1 is an exploded perspective view showing an example of an embodiment of a high-frequency circuit board and an electric circuit board connected thereto.
 高周波回路基板には、誘電体基板1の表面に線路導体3が形成されている。一方、電気回路基板には、誘電体基板2の裏面に線路導体4が形成されている。電気回路基板の線路導体4は誘電体基板2の裏面(図中、誘電体基板2の下面)に形成されている。図1において、線路導体4は誘電体基板2を透視した形で示されている。誘電体基板2は二点鎖線で示されている。線路導体4は線路導体3に接続される他の接続導体となる。 The line conductor 3 is formed on the surface of the dielectric substrate 1 in the high-frequency circuit board. On the other hand, a line conductor 4 is formed on the back surface of the dielectric substrate 2 in the electric circuit substrate. The line conductor 4 of the electric circuit board is formed on the back surface of the dielectric substrate 2 (the lower surface of the dielectric substrate 2 in the figure). In FIG. 1, the line conductor 4 is shown in a form seen through the dielectric substrate 2. The dielectric substrate 2 is indicated by a two-dot chain line. The line conductor 4 is another connection conductor connected to the line conductor 3.
 なお、誘電体基板1または誘電体基板2の表面に線路導体3または線路導体4が形成されることは必須なことではない。例えば、線路導体3または線路導体4が金属板様のもので形成され、誘電体基板1または誘電体基板2によって支持されていなくてもよい。 In addition, it is not essential that the line conductor 3 or the line conductor 4 is formed on the surface of the dielectric substrate 1 or the dielectric substrate 2. For example, the line conductor 3 or the line conductor 4 may be formed of a metal plate-like material and may not be supported by the dielectric substrate 1 or the dielectric substrate 2.
 そして、線路導体3は、線路導体4が接続される接続端に線路導体3の線幅よりも広い幅広部3aが形成されている。接続端とは、線路導体3の一端であって、線路導体4の一端と重ねられて線路導体4と接続される部分である。接続端において、複数の幅広部3aの間には幅広部3aよりも幅の狭い幅狭部3bが形成されている。 The line conductor 3 has a wide portion 3a that is wider than the line width of the line conductor 3 at the connection end to which the line conductor 4 is connected. The connection end is one end of the line conductor 3 and is a portion that is overlapped with one end of the line conductor 4 and connected to the line conductor 4. At the connection end, a narrow portion 3b narrower than the wide portion 3a is formed between the plurality of wide portions 3a.
 図1において、幅広部3aは、線路導体3の線路方向に沿って2つが隣接するように形成されている。幅広部3aは、2以上の複数を隣接させるように形成され、それら幅広部3aの間に幅狭部3bが形成される。このような接続端が接続パッドとして用いられる。接続端の容量成分を少なくする観点および接合力を確保する観点からは、幅広部3aおよび幅狭部3bの数を多くし過ぎると不利になる傾向がある。 In FIG. 1, the wide part 3a is formed so that two may adjoin along the line direction of the line conductor 3. FIG. The wide portion 3a is formed so that two or more are adjacent to each other, and a narrow portion 3b is formed between the wide portions 3a. Such a connection end is used as a connection pad. From the viewpoint of reducing the capacitance component at the connection end and securing the bonding force, if the number of the wide portions 3a and the narrow portions 3b is excessively increased, it tends to be disadvantageous.
 線路導体4と線路導体3とは、線路導体4を線路導体3の接続端に重ねて、線路導体4と線路導体3とを銀(Ag)ろう、金(Au)-錫(Sn)半田やAgエポキシ(Agの金属粉末を含有するエポキシ樹脂)等の導電性接合材等で接合すればよい。接合位置に関しては、線路導体4の端が線路導体3の上記の一端と反対側に位置する他端側の一番奥に形成されている幅広部3aと重なり合うように接合するのが好ましい。線路導体4の端が一番奥の幅広部3aを超えて線路導体3に接合されてもよいが、好ましくは、一番奥の幅広部3aの形成範囲内に線路導体4の端を配置するのがよい。 The line conductor 4 and the line conductor 3 are formed by superimposing the line conductor 4 on the connection end of the line conductor 3 and connecting the line conductor 4 and the line conductor 3 to silver (Ag) brazing, gold (Au) -tin (Sn) solder, What is necessary is just to join by electroconductive joining materials etc., such as Ag epoxy (epoxy resin containing the metal powder of Ag). As for the joining position, it is preferable that the end of the line conductor 4 is joined so as to overlap with the wide portion 3a formed at the innermost end on the other end side opposite to the one end of the line conductor 3. The end of the line conductor 4 may be joined to the line conductor 3 beyond the innermost wide portion 3a, but preferably the end of the line conductor 4 is disposed within the formation range of the innermost wide portion 3a. It is good.
 線路導体3に幅広部3aが設けられているので、その分、線路導体4が線路導体3の中心からずれて配置されても線路導体4と線路導体3との導通を確保することができる。線路導体4の線路方向と線路導体3の線路方向とが平行ではなく、少し角度をもって配置されたとしても、線路導体3の両側に突出する幅広部3aが接続端に少なくとも2つ設けられているので、導通を確保することができる。また、線路導体3と線路導体4との接続抵抗が大きくなり過ぎないように接続することができる。 Since the wide portion 3 a is provided in the line conductor 3, it is possible to ensure electrical connection between the line conductor 4 and the line conductor 3 even if the line conductor 4 is displaced from the center of the line conductor 3. Even if the line direction of the line conductor 4 and the line direction of the line conductor 3 are not parallel and are arranged at a slight angle, at least two wide portions 3a protruding on both sides of the line conductor 3 are provided at the connection end. Therefore, conduction can be ensured. Moreover, it can connect so that the connection resistance of the line conductor 3 and the line conductor 4 may not become large too much.
 この場合、線路導体3または線路導体4は、接地導体5,6等との間で容量成分を生ずる。ところが、線路導体3の接続端が複数の幅広部3aに分けて形成されているとともに、複数の幅広部3aの間には幅広部3aよりも幅の狭い幅狭部3bが形成されているので、線路導体3の接続端における容量成分の増加を抑えることができる。 In this case, the line conductor 3 or the line conductor 4 generates a capacitance component between the ground conductors 5 and 6 and the like. However, the connection end of the line conductor 3 is formed by being divided into a plurality of wide portions 3a, and a narrow portion 3b narrower than the wide portion 3a is formed between the plurality of wide portions 3a. The increase in the capacitance component at the connection end of the line conductor 3 can be suppressed.
 次に、本発明の一実施形態に係る線路導体3,4を高周波用多層回路基板に用いた例について説明する。 Next, an example in which the line conductors 3 and 4 according to an embodiment of the present invention are used for a high-frequency multilayer circuit board will be described.

 誘電体基板1は第1誘電体基板1、線路導体3は第1線路導体3、誘電体基板2は第2誘電体基板2、線路導体4は第2線路導体4とも呼称するが、以下説明では、符合によって区別可能なので、単に誘電体基板1、線路導体3、誘電体基板2、線路導体4と記す。 The dielectric substrate 1 is also called the first dielectric substrate 1, the line conductor 3 is also called the first line conductor 3, the dielectric substrate 2 is also called the second dielectric substrate 2, and the line conductor 4 is also called the second line conductor 4. Then, since they can be distinguished by the signs, they are simply referred to as dielectric substrate 1, line conductor 3, dielectric substrate 2, and line conductor 4.
 かかる高周波回路基板は、図2Cに示すように、線路導体3を有する誘電体基板1と線路導体4を有する誘電体基板2とが、線路導体3の一端と線路導体4の一端とを重ね合わせて積層されたものである。すなわち高周波回路基板は、線路導体3,4が、積層された誘電体基板1および誘電体基板2の層間に形成されている。一本に繋ぎ合わされた線路導体3,4は、線路導体3と線路導体4とが接続された接続部を有する。接続部は、線路導体3の一端と線路導体4の一端とが重ねられて、互いに接続されている部分である。接続部には線幅が広い複数の幅広部3aと、幅広部3aの間に配置された幅広部3aよりも線幅の狭い幅狭部3bとが形成されている。 As shown in FIG. 2C, such a high-frequency circuit board includes a dielectric substrate 1 having a line conductor 3 and a dielectric substrate 2 having a line conductor 4 that overlap one end of the line conductor 3 and one end of the line conductor 4. Are stacked. That is, in the high-frequency circuit board, the line conductors 3 and 4 are formed between the laminated dielectric substrate 1 and dielectric substrate 2. The line conductors 3 and 4 connected to each other have a connection portion to which the line conductor 3 and the line conductor 4 are connected. The connection portion is a portion where one end of the line conductor 3 and one end of the line conductor 4 are overlapped and connected to each other. A plurality of wide portions 3a having a wide line width and a narrow portion 3b having a narrower line width than the wide portion 3a disposed between the wide portions 3a are formed in the connection portion.
 線路導体3は、接続部に幅広部3aを有しているので、誘電体基板1と誘電体基板2とを積層する際に多少の積層ずれが生じたとしても、線路導体3と線路導体4とを導通させることができる。 Since the line conductor 3 has the wide portion 3a at the connecting portion, even if a slight misalignment occurs when the dielectric substrate 1 and the dielectric substrate 2 are laminated, the line conductor 3 and the line conductor 4 Can be conducted.
 しかも、接続端に一体の大きな接続パッドを形成するのに対し、複数の幅広部3aを設けて導通を確保している。複数の幅広部3aの間には幅狭部3bが配置されているので、接続部の容量成分を小さくすることができ、線路導体3および線路導体4で形成される高周波線路上の大きなインピーダンス不整合を来さないようにすることができる。 Moreover, in contrast to forming a large connection pad integrally formed at the connection end, a plurality of wide portions 3a are provided to ensure conduction. Since the narrow portion 3b is disposed between the plurality of wide portions 3a, the capacitance component of the connection portion can be reduced, and a large impedance difference on the high-frequency line formed by the line conductor 3 and the line conductor 4 can be obtained. It is possible to prevent alignment.
 図7Aは、図2に示す高周波回路基板の反射損失をシミュレーションした結果をプロットした線図である。破線は、図8に示されるような従来の四角形の接続パッドを介して線路導体を接続した場合の反射損失を示す。また、実線は、本発明の一実施形態に係る高周波回路基板の反射損失を示す。接続部に幅広部3aと幅狭部3bとを配置した実線で示されるシミュレーション結果の方が、反射損失が少ないことが判る。 FIG. 7A is a diagram in which the result of simulating the reflection loss of the high-frequency circuit board shown in FIG. 2 is plotted. The broken line shows the reflection loss when the line conductor is connected through the conventional rectangular connection pad as shown in FIG. The solid line indicates the reflection loss of the high-frequency circuit board according to the embodiment of the present invention. It can be seen that the simulation result indicated by the solid line in which the wide portion 3a and the narrow portion 3b are arranged in the connection portion has less reflection loss.
 図7Bは、同様にして求めた挿入損失のシミュレーション結果を示す線図である。破線で示される従来のものに比べ、実線で示される本発明の一実施形態に係る高周波回路基板の方が、挿入損失が少ないことが判る。 FIG. 7B is a diagram showing a simulation result of insertion loss obtained in the same manner. It can be seen that the insertion loss is lower in the high-frequency circuit board according to the embodiment of the present invention indicated by the solid line than in the conventional one indicated by the broken line.
 図1および図2に示す線路導体3は、図3A,図3B,図3C,図3D,図3E,図3F,図3G,図3H,図3I,図3Jに示すように、様々な形状のものとすることができる。図3Aは、幅広部3aを2つ設けた場合を示す。図3Bは、複数の幅広部3aを、2つより多く(4つ)設けた場合を示す。 The line conductor 3 shown in FIGS. 1 and 2 has various shapes as shown in FIGS. 3A, 3B, 3C, 3D, 3E, 3F, 3G, 3H, 3I, and 3J. Can be. FIG. 3A shows a case where two wide portions 3a are provided. FIG. 3B shows a case where a plurality of (four) wide portions 3a are provided.
 図3C,図3Dは、それぞれの幅広部3aの幅を異ならせた場合を示す。図3Cは、先端側(図中左側)の幅広部3aを後端側(図中右側)の幅広部3aよりも広い幅とした場合を示す。図3Dは、逆に先端側の幅広部3aよりも後端側の幅広部3aの幅を広くした場合を示す。 3C and 3D show cases where the widths of the wide portions 3a are made different. FIG. 3C shows a case where the wide portion 3a on the front end side (left side in the drawing) is wider than the wide portion 3a on the rear end side (right side in the drawing). FIG. 3D shows a case where the width of the wide portion 3a on the rear end side is made wider than that of the wide portion 3a on the front end side.
 また、図3E,図3F,図3G,図3H,図3I,図3Jは、幅広部3aの形状を線路導体3から線路導体3の幅方向に離れるに従って、線路導体3の線路方向の幅が狭くなるように形成する各例を示すものである。幅広部3aの形状は、線路導体3のエッジから離れるに従って、直線状,曲線状またはその組合せ等、いずれでもよい。長方形の幅広部3aとした場合に比べて、線路導体3の線路方向に対して幅広部3aのエッジが直角に交わらず鈍角で交わることになる。鈍角で交わることによって、幅広部3aが設けられた部位におけるインピーダンスの変化を緩やかなものにすることができる。 3E, FIG. 3F, FIG. 3G, FIG. 3H, FIG. 3I, and FIG. 3J show that the width of the line conductor 3 in the line direction increases as the shape of the wide portion 3a increases from the line conductor 3 in the width direction of the line conductor 3. Each example is formed so as to be narrow. The shape of the wide portion 3a may be any of a linear shape, a curved shape, or a combination thereof as the distance from the edge of the line conductor 3 increases. Compared with the case of the rectangular wide portion 3a, the edges of the wide portion 3a intersect at an obtuse angle with respect to the line direction of the line conductor 3 instead of at right angles. By intersecting at an obtuse angle, the change in impedance at the site where the wide portion 3a is provided can be made gradual.
 図3Eは、2つの幅広部3aの内、線路導体3の先端側から2つ目(右側)の幅広部3aの辺を傾斜させた例を示す。幅広部3aは、線路導体3の先端と反対側の辺が幅方向に離れるに従って線路導体3の先端側に傾斜している。 FIG. 3E shows an example in which the side of the second wide portion 3a (right side) from the front end side of the line conductor 3 is inclined among the two wide portions 3a. The wide portion 3a is inclined toward the front end side of the line conductor 3 as the side opposite to the front end of the line conductor 3 is separated in the width direction.
 図3Fは、2つの幅広部3aの両方の辺を傾斜させた例を示す。両方の幅広部3aは、線路導体3の先端と反対側の辺が幅方向に離れるに従って線路導体3の先端側に傾斜している。 FIG. 3F shows an example in which both sides of the two wide portions 3a are inclined. Both wide portions 3a are inclined toward the tip end side of the line conductor 3 as the side opposite to the tip end of the line conductor 3 is separated in the width direction.
 図3Gは、2つの幅広部3aの内、線路導体3の先端側から2つ目(右側)の幅広部3aにおいて、両方の辺を傾斜させた例を示す。幅広部3aの線路導体3の先端側および後端側の両方の辺が、傾斜させて設けられている。 FIG. 3G shows an example in which both sides are inclined in the second wide portion 3a (right side) from the front end side of the line conductor 3 among the two wide portions 3a. Both the front end side and the rear end side of the line conductor 3 of the wide portion 3a are provided to be inclined.
 図3Hは、2つの幅広部3aの内、線路導体3の先端側の幅広部3aにおいて、両方の辺を傾斜させた例を示す。幅広部3aの線路導体3の先端側および後端側の両方の辺が、傾斜させて設けられている。 FIG. 3H shows an example in which both sides are inclined in the wide portion 3a on the tip end side of the line conductor 3 among the two wide portions 3a. Both the front end side and the rear end side of the line conductor 3 of the wide portion 3a are provided to be inclined.
 図3Iは、2つの幅広部3aの両方とも辺を傾斜させた例を示す。両方の幅広部3aは、線路導体3の先端側および後端側の両方の辺が、傾斜させて設けられている。 FIG. 3I shows an example in which the sides of both of the two wide portions 3a are inclined. Both wide portions 3a are provided with both sides on the front end side and rear end side of the line conductor 3 inclined.
 図3Jは、2つの幅広部3aの両方とも辺を半円状または円弧状に傾斜させた例を示す。両方の幅広部3aは、線路導体3の先端側および後端側の両方の辺が、半円状または円弧状に傾斜させて設けられている。 FIG. 3J shows an example in which the sides of both of the two wide portions 3a are inclined in a semicircular shape or an arc shape. Both of the wide portions 3a are provided such that both the front end side and the rear end side of the line conductor 3 are inclined in a semicircular shape or an arc shape.
 また、図4Aに示すように、複数の幅広部3aに挟まれる幅狭部3bの線路導体3の線幅は、線路導体3の接続部を除く部分の線幅よりも狭く形成してもよい。幅広部3aに挟まれる幅狭部3bは、線路導体4と重ねて接合されるので、導体量が多くなり、その分、容量成分が大きくなる傾向がある。線路導体3の線幅を狭くすることによって、この容量成分の増加を少なくすることができる。 Further, as shown in FIG. 4A, the line width of the line conductor 3 of the narrow portion 3b sandwiched between the plurality of wide portions 3a may be formed narrower than the line width of the portion excluding the connection portion of the line conductor 3. . Since the narrow portion 3b sandwiched between the wide portions 3a is overlapped and joined to the line conductor 4, the amount of the conductor increases, and the capacitance component tends to increase accordingly. By increasing the line width of the line conductor 3, the increase in the capacitance component can be reduced.
 なお、幅狭部3bの線幅とは、幅狭部3bにおける線路導体3の線路方向に対して直角な方向の長さ、すなわち線路導体3の幅を意味する。また、幅狭部3bにおいて、最小の幅の値を幅狭部3bの線幅という。一方、幅広部3aの線幅とは、幅広部3aにおいて最大の幅の値を幅広部3aの線幅という。 Note that the line width of the narrow portion 3b means the length of the narrow portion 3b in the direction perpendicular to the line direction of the line conductor 3, that is, the width of the line conductor 3. In the narrow portion 3b, the minimum width value is referred to as the line width of the narrow portion 3b. On the other hand, the line width of the wide portion 3a refers to the maximum width value of the wide portion 3a as the line width of the wide portion 3a.
 また、図4Bに示すように、線路導体3の、幅広部3aが形成される接続端または接続部に隣接する位置に、線路導体3の線幅を狭くした領域3cを設けてもよい。接続端または接続部では幅広部3aが形成されて、容量成分が大きくなり、インピーダンスが低くなる。そこで、接続端または接続部の隣接する位置にインピーダンスの高い領域3cを配置すると、接続端または接続部におけるインピーダンスの低下を補償させることができる。そして線路導体3および線路導体4によって形成される高周波線路上のインピーダンス不整合を緩和することができる。領域3c部分の線幅は、例えば接続端または接続部から離れた線路導体3の線幅の70~80%の幅とすればよい。 Further, as shown in FIG. 4B, a region 3c in which the line width of the line conductor 3 is narrowed may be provided at a connection end of the line conductor 3 where the wide portion 3a is formed or a position adjacent to the connection portion. A wide portion 3a is formed at the connection end or the connection portion, the capacitance component is increased, and the impedance is decreased. Therefore, if the high impedance region 3c is arranged at a position adjacent to the connection end or the connection portion, it is possible to compensate for a decrease in impedance at the connection end or the connection portion. And the impedance mismatch on the high frequency line formed by the line conductor 3 and the line conductor 4 can be reduced. The line width of the region 3c may be 70 to 80% of the line width of the line conductor 3 away from the connection end or connection portion, for example.
 同様に、線路導体4においても、接続端または接続部に隣接する位置に線路導体4の線幅を狭くした導体領域4cを設けておくのがよい。領域3cまたは領域4cを、幅広部3aの間の幅狭部3bに対して第2幅狭部とも呼称する。 Similarly, in the line conductor 4, it is preferable to provide a conductor region 4c in which the line width of the line conductor 4 is narrowed at a position adjacent to the connection end or the connection portion. The region 3c or the region 4c is also referred to as a second narrow portion with respect to the narrow portion 3b between the wide portions 3a.
 なお、図1,図2A,図2B,図2Cにおいて、線路導体3および線路導体4の両側には、所定距離を隔てて線路導体3および線路導体4と平行に接地導体5,6が近接配置されている。線路導体3および線路導体4は、いわゆるコプレーナ線路として動作する。 In FIG. 1, FIG. 2A, FIG. 2B, and FIG. 2C, ground conductors 5 and 6 are arranged close to each other on both sides of the line conductor 3 and the line conductor 4 in parallel with the line conductor 3 and the line conductor 4 at a predetermined distance. Has been. The line conductor 3 and the line conductor 4 operate as a so-called coplanar line.
 また、図には示していないが、誘電体基板1および誘電体基板2の線路導体3および線路導体4が形成されている面と反対側の面、または誘電体基板1および誘電体基板2の内層にも、接地導体を設ける場合がある。これによって、線路導体3および線路導体4は、いわゆるグランデッドコプレーナ線路として動作する。また、線路導体3および線路導体4は、マイクロストリップ線路としてもよい。 Although not shown in the drawing, the surface of the dielectric substrate 1 and the dielectric substrate 2 opposite to the surface on which the line conductor 3 and the line conductor 4 are formed, or the dielectric substrate 1 and the dielectric substrate 2. In some cases, a ground conductor is also provided on the inner layer. Thereby, the line conductor 3 and the line conductor 4 operate as a so-called grounded coplanar line. The line conductor 3 and the line conductor 4 may be microstrip lines.
 誘電体基板1または誘電体基板2は、アルミナ質焼結体や窒化アルミニウム質焼結体,ムライト質焼結体,ガラスセラミックス等のセラミックス、または、エポキシ樹脂、ポリイミドフィルム等の樹脂から選択された材料から成る。誘電体基板1または誘電体基板2から成る高周波回路基板は、このようなセラミック基板、ガラスエポキシ基板、またはフレキシブル基板(FPC)として作製される。 The dielectric substrate 1 or the dielectric substrate 2 was selected from an alumina sintered body, an aluminum nitride sintered body, a mullite sintered body, ceramics such as glass ceramics, or a resin such as an epoxy resin or a polyimide film. Made of material. The high-frequency circuit board composed of the dielectric substrate 1 or the dielectric substrate 2 is manufactured as such a ceramic substrate, a glass epoxy substrate, or a flexible substrate (FPC).
 誘電体基板1または誘電体基板2がセラミックスから成る場合には、線路導体3,4および接地導体5,6は、例えばメタライズ法による金属導体層により形成される。 When the dielectric substrate 1 or the dielectric substrate 2 is made of ceramics, the line conductors 3 and 4 and the ground conductors 5 and 6 are formed by a metal conductor layer by, for example, a metallization method.
 例えば、まず、図1,図2Bに示されるように、線路導体3と接地導体5とが誘電体基板1に形成される場合であれば、誘電体基板1となるセラミックグリーンシートの裏面に線路導体3および接地導体5となるタングステン(W),モリブデン(Mo),マンガン(Mn)等から成る金属ペーストをスクリーン印刷法によって印刷塗布する。誘電体基板2も同様に、その表面に線路導体4および接地導体6となるW,Mo,Mn等から成る金属ペーストをスクリーン印刷法によって印刷塗布する。 For example, as shown in FIG. 1 and FIG. 2B, first, if the line conductor 3 and the ground conductor 5 are formed on the dielectric substrate 1, the line is formed on the back surface of the ceramic green sheet to be the dielectric substrate 1. A metal paste made of tungsten (W), molybdenum (Mo), manganese (Mn) or the like to be the conductor 3 and the ground conductor 5 is applied by screen printing. Similarly, the dielectric substrate 2 is printed with a metal paste made of W, Mo, Mn or the like to be the line conductor 4 and the ground conductor 6 on the surface by screen printing.
 次に、図2Cに示す積層された高周波回路基板とする場合は、誘電体基板1となるセラミックグリーンシートの線路導体3となる金属ペーストの接続端と誘電体基板2となるセラミックグリーンシートの線路導体4となる金属ペーストの一端とが重なるようにして誘電体基板1および誘電体基板2となるセラミックグリーンシート同士を上下に重ねあわせる。その他配線層があれば、それら配線層が形成されたセラミックグリーンシートをさらに重ねて、両面から圧力を加え、セラミックグリーンシート同士を圧着する。 Next, when the laminated high frequency circuit board shown in FIG. 2C is used, the connection end of the metal paste that becomes the line conductor 3 of the ceramic green sheet that becomes the dielectric substrate 1 and the line of the ceramic green sheet that becomes the dielectric substrate 2 The ceramic green sheets to be the dielectric substrate 1 and the dielectric substrate 2 are stacked one above the other so that one end of the metal paste to be the conductor 4 overlaps. If there are other wiring layers, the ceramic green sheets on which the wiring layers are formed are further stacked, pressure is applied from both sides, and the ceramic green sheets are pressed together.
 最後に、この積層体を高温炉に投入することによって、セラミックグリーンシートが焼成され、セラミック基板となる。同時に、金属ペーストが焼成されて線路導体3,4を有する高周波回路基板となる。 Finally, the ceramic green sheet is fired by putting this laminate into a high-temperature furnace to form a ceramic substrate. At the same time, the metal paste is fired to obtain a high-frequency circuit board having the line conductors 3 and 4.
 なお、線路導体3、接地導体5、線路導体4および接地導体6は、薄膜形成法によって形成されてもよく、その場合、線路導体3,4および接地導体5,6は窒化タンタル(TaN),ニクロム(Ni-Cr合金),チタン(Ti),パラジウム(Pd),白金(Pt)等から形成され、誘電体基板1または誘電体基板2と成るセラミックグリーンシートを焼成した後にスパッタリング等の薄膜形成法により形成される。 The line conductor 3, the ground conductor 5, the line conductor 4 and the ground conductor 6 may be formed by a thin film forming method. In this case, the line conductors 3 and 4 and the ground conductors 5 and 6 are made of tantalum nitride (Ta 2 N ), Nichrome (Ni—Cr alloy), Titanium (Ti), Palladium (Pd), Platinum (Pt), etc., and after firing the ceramic green sheet to be the dielectric substrate 1 or the dielectric substrate 2, sputtering, etc. It is formed by a thin film forming method.
 また、誘電体基板1,2の表面に銅(Cu)等の箔をラミネートし、その後、Cu箔をエッチングして線路導体3,4等を形成してもよい。 Further, a foil such as copper (Cu) may be laminated on the surfaces of the dielectric substrates 1 and 2 and then the Cu foil may be etched to form the line conductors 3 and 4.
 以上により、誘電体基板1,2の間で高周波信号の伝送を行なうことが可能な高周波伝送用の回路基板を作製できる。 As described above, a circuit board for high frequency transmission capable of transmitting a high frequency signal between the dielectric substrates 1 and 2 can be manufactured.
 高周波回路基板の典型的な一例として、線路導体3の線幅は、0.1mm程度、幅広部3aの幅は0.3mm程度、幅広部3aの長さ(線路導体3の線路方向の)は0.08~0.1mm程度、幅広部3aの間の幅狭部3bの長さは0.25mm程度である。幅広部3aの長さは線路導体3を流れる高周波信号の波長の10%以下とすれば、インピーダンス変化の影響を小さくすることができる。 As a typical example of the high-frequency circuit board, the line width of the line conductor 3 is about 0.1 mm, the width of the wide portion 3a is about 0.3 mm, and the length of the wide portion 3a (in the line direction of the line conductor 3) is The length of the narrow portion 3b between about 0.08 to 0.1 mm and the wide portion 3a is about 0.25 mm. If the length of the wide portion 3a is 10% or less of the wavelength of the high-frequency signal flowing through the line conductor 3, the influence of the impedance change can be reduced.
 次に、上記高周波回路基板を用いた高周波半導体パッケージ(以下、単にパッケージともいう)および高周波装置の一例について図5,図6に基づいて説明する。これら図は、それぞれ高周波半導体パッケージおよび高周波装置の実施の形態の一例を示す斜視図であり、11は基体、12は枠体、13は入出力端子である。 Next, an example of a high-frequency semiconductor package (hereinafter also simply referred to as a package) and a high-frequency device using the above-described high-frequency circuit board will be described with reference to FIGS. These drawings are perspective views showing examples of embodiments of the high-frequency semiconductor package and the high-frequency device, respectively, 11 is a base, 12 is a frame, and 13 is an input / output terminal.
 パッケージは、上面の中央部に半導体素子が載置される載置部11aを有する基体11と、この基体11の上面に載置部11aを囲繞するように取着され、側部に形成された貫通孔または切欠きからなる入出力端子13の取付部12aが形成された枠体12と、取付部12aに嵌着された入出力端子13とを具備している。 The package has a base 11 having a mounting portion 11a on which a semiconductor element is mounted at the center of the upper surface, and is attached to the upper surface of the base 11 so as to surround the mounting portion 11a, and is formed on a side portion. The frame body 12 in which the attaching part 12a of the input / output terminal 13 which consists of a through-hole or a notch was formed, and the input / output terminal 13 fitted by the attaching part 12a are comprised.
 入出力端子13は複数のセラミックグリーンシートを積層して形成したものである。入出力端子13のうち、第2層13aおよび第3層13bがそれぞれ上述の誘電体基板2および誘電体基板1に相当し、第2層13aの上面に線路導体4および接地導体6が形成されている。第3層13bの下面には、線路導体3および接地導体5が形成されている。他の層には、それぞれ接地導体層や他の線路導体パターンが形成されている。 The input / output terminal 13 is formed by laminating a plurality of ceramic green sheets. Of the input / output terminal 13, the second layer 13a and the third layer 13b correspond to the dielectric substrate 2 and the dielectric substrate 1, respectively, and the line conductor 4 and the ground conductor 6 are formed on the upper surface of the second layer 13a. ing. A line conductor 3 and a ground conductor 5 are formed on the lower surface of the third layer 13b. A ground conductor layer and other line conductor patterns are formed on the other layers, respectively.
 そして、これらセラミックグリーンシートを積層した後、高温で焼成すると入出力端子13が完成する。なお、焼成後において積層された入出力端子13は一体のものとなる。図5において層間として示した破線は便宜上のものである。 Then, after laminating these ceramic green sheets, firing at a high temperature completes the input / output terminal 13. Note that the input / output terminals 13 stacked after firing are integrated. The broken lines shown as layers in FIG. 5 are for convenience.
 また、線路導体3,線路導体4,接地導体5,接地導体6等の金属導体層の露出する表面には、ニッケル(Ni)や金(Au)等の耐食性に優れる金属を1~20μm程度の厚さで被着させておくとよい。これら金属導体の酸化腐食を防止する。また、線路導体3と外部高周波線路(図示せず)との接続、および電子部品16と線路導体4とのボンディングワイヤ等の電気的接続手段を介しての接続を容易にする。従って、金属導体層の露出表面には、例えば、厚さ0.5μm~10μmのNiメッキ層と厚さ0.1~5μm程度のAuめっき層とが電解めっき法や無電解めっき法により順次被着されているのが好ましい。 Further, on the exposed surface of the metal conductor layer such as the line conductor 3, the line conductor 4, the ground conductor 5, and the ground conductor 6, a metal having excellent corrosion resistance such as nickel (Ni) or gold (Au) is about 1 to 20 μm. It is good to make it adhere by thickness. Prevents oxidative corrosion of these metal conductors. Further, the connection between the line conductor 3 and the external high-frequency line (not shown) and the connection between the electronic component 16 and the line conductor 4 via an electrical connection means such as a bonding wire are facilitated. Therefore, on the exposed surface of the metal conductor layer, for example, a Ni plating layer having a thickness of 0.5 μm to 10 μm and an Au plating layer having a thickness of about 0.1 to 5 μm are sequentially coated by an electrolytic plating method or an electroless plating method. Preferably it is worn.
 基体11は、上面にIC,LSI,半導体レーザ(LD),フォトダイオード(PD)等の半導体素子を載置するための載置部11aを有している。図6では載置部11aを基体11および枠体12で囲まれる凹部の底面とした例を示した。載置部11aには、基体11の上面にペルチェ素子や回路基板等の載置台15を介して半導体素子16を載置してもよい。 The base 11 has a mounting portion 11a on the top surface for mounting semiconductor elements such as IC, LSI, semiconductor laser (LD), photodiode (PD) and the like. FIG. 6 shows an example in which the mounting portion 11 a is a bottom surface of a recess surrounded by the base body 11 and the frame body 12. A semiconductor element 16 may be mounted on the mounting portion 11 a on the upper surface of the base 11 via a mounting table 15 such as a Peltier element or a circuit board.
 基体11は、Fe-Ni-Co合金,銅(Cu)-タングステン(W)合金等の金属、またはAl質焼結体,AlN質焼結体,3Al・2SiO質焼結体等のセラミックスから成る。 Base 11, Fe-Ni-Co alloy, copper (Cu) - tungsten (W) metal such as alloy, or Al 2 O 3 sintered material,, AlN sintered material, 3Al 2 O 3 · 2SiO 2 Quality grilled Consists of ceramics such as ligatures.
 基体11が金属から成る場合は、そのインゴットに圧延加工や打ち抜き加工等の従来周知の金属加工法を施すことによって所定形状に製作される。一方、基体11がセラミックスから成る場合は、その原料粉末に適当な有機バインダや溶剤等を添加混合してペースト状とする。このペーストをドクターブレード法やカレンダーロール法等によってセラミックグリーンシートとし、しかる後、このセラミックグリーンシートに適当な打ち抜き加工を施して、さらにこれらを複数枚積層し約1600℃の高温で焼成することによって作製される。 When the substrate 11 is made of metal, the ingot is manufactured in a predetermined shape by applying a conventionally known metal processing method such as rolling or punching.
