はじめに、本発明に関わる樹脂封止型半導体装置の第1例を図1に基づいて説明する。 第1例は、外部回路と接続するための外部端子部112と、半導体素子と接続するための内部端子部111をその一部として含むリード部114とを、一体的に連結してなる端子部材で、且つ、ハーフエッチング加工法を用いて、加工用素材(図示していない)から、外部端子部112の少なくとも一部を加工用素材の厚さの厚肉にし、リード部114をハーフエッチングにて薄肉にしている端子部材110を、複数個と、センターパッド配列の半導体素子120とを用い、半導体素子120の所定の端子部121と所定の端子部材の内部端子部111とをワイヤボンディング接続して、樹脂封止した平板状方形の樹脂封止型半導体装置である。
そして、各端子部材110を同じ向きにし、外部端子部112の表裏の面およびリード部114のエッチング面114aが、それぞれ、一平面上に、揃うようにし、周辺部に、外部端子部112を外側、内部端子部111を内側に向けて、各端子部材110を配しており、内部端子部111の端子面をエッチング面114aとして、且つ、リード部114のハーフエッチング面114aでない側の面を半導体素子の端子面120aに載せるLOC(Lead On Chip)構造のもので、各端子部材110のハーフエッチング面114a側の外部端子部の厚肉部の一面と外側側面とを、それぞれ端子面112a,112bとして露出させ、これ以外を樹脂中にして樹脂封止されている。
First, a first example of a resin-encapsulated semiconductor device according to the present invention will be described with reference to FIG. The first example is a terminal member formed by integrally connecting an external terminal portion 112 for connecting to an external circuit and a lead portion 114 including, as a part thereof, an internal terminal portion 111 for connecting to a semiconductor element. In addition, by using a half etching method, at least a part of the external terminal portion 112 is made thicker than the processing material from a processing material (not shown), and the lead portion 114 is half etched. A plurality of thin terminal members 110 and a center pad array semiconductor element 120 are used, and a predetermined terminal portion 121 of the semiconductor element 120 and an internal terminal portion 111 of the predetermined terminal member are connected by wire bonding. Thus, a resin-sealed flat rectangular resin-sealed semiconductor device.
Then, each terminal member 110 is oriented in the same direction, the front and back surfaces of the external terminal portion 112 and the etching surface 114a of the lead portion 114 are aligned on a single plane, and the external terminal portion 112 is placed outside on the peripheral portion. Each terminal member 110 is arranged with the internal terminal portion 111 facing inward, the terminal surface of the internal terminal portion 111 is used as an etching surface 114a, and the surface of the lead portion 114 that is not the half etching surface 114a is a semiconductor. The LOC (Lead On Chip) structure is placed on the terminal surface 120a of the element, and one surface and the outer side surface of the thick portion of the external terminal portion on the half etching surface 114a side of each terminal member 110 are connected to the terminal surfaces 112a and 112b, respectively. It is exposed and is sealed with resin other than this in resin.

本例は、端子部材110の加工用素材(図示していない)の一面側が、露出するようにして樹脂封止していることにより、薄型化が達成できる。
また、半導体素子自体の厚さの薄化に対応しても、薄型化が達成できる。
本例では、加工用素材の厚さと半導体素子の総厚により、その厚さは決まる。
また、本例においては、ワイヤボンディング接続をとっていることにより、接続作業性を良いものとし、且つ、接続信頼性を良いものとしている。
また、本例は、後述する、(図9、図10に示す)本発明に関わる樹脂封止型半導体装置の製造方法により、面付け状態で作製できる、量産性に適した構造といえる。
また、本例は、樹脂封止工程(モールド工程)においては、特別な形状にキャビティーを設ける必要はなく、平板状のものでその両側を抑えた状態でモールドが簡単に行える構造で、設備の面からも好ましい構造と言える。
In this example, since the one surface side of the processing material (not shown) of the terminal member 110 is resin-sealed so as to be exposed, a reduction in thickness can be achieved.
Further, even if the thickness of the semiconductor element itself is reduced, the thickness can be reduced.
In this example, the thickness is determined by the thickness of the processing material and the total thickness of the semiconductor elements.
Moreover, in this example, the wire bonding connection is used, so that the connection workability is good and the connection reliability is good.
Also, this example will be described later, (Figure 9, shown in FIG. 10) by the production method of the resin-sealed semiconductor device according to the present invention, can be prepared by the imposition state, it can be said that suitable for mass production structure.
In addition, this example does not require a special cavity in the resin sealing process (molding process), and it has a flat structure and can be easily molded with both sides held down. From this aspect, it can be said that the structure is preferable.

端子部材110は、Cu、Cu系合金、42%Ni−Fe系合金等が挙げられるが、通常は、導電性等から、Cu、Cu系合金が用いられる。
第1の例においては、外部端子部112の外側側面の端子面112bは切断部で、それ以外の表面には、接続用のめっき層が設けられている。
接続用のめっき層としては、半田めっき層、金めっき層、銀めっき層、パラジウムめっき層、錫めっき層から選ばれた1つの金属めっき層が用いられる。
封止用樹脂140としては、通常、エポキシ系のものが用いられるが、これに限定はされない。
The terminal member 110 may be Cu, Cu-based alloy, 42% Ni—Fe-based alloy, or the like, but usually Cu or Cu-based alloy is used from the viewpoint of conductivity.
In the first example, the terminal surface 112b on the outer side surface of the external terminal portion 112 is a cut portion, and a plating layer for connection is provided on the other surface.
As the plating layer for connection, one metal plating layer selected from a solder plating layer, a gold plating layer, a silver plating layer, a palladium plating layer, and a tin plating layer is used.

次に、本発明の樹脂封止型半導体装置の実施の形態の第1の例を図2に基づいて説明する。
第1の例の樹脂封止型半導体装置も、図1に示す本発明に関わる樹脂封止型半導体装置の第1例と同様に、外部回路と接続するための外部端子部112と、半導体素子と接続するための内部端子部111をその一部として含むリード部114とを、一体的に連結してなる同じ形状の端子部材で、且つ、ハーフエッチング加工法を用いて、加工用素材(図示していない)から、外部端子部112の少なくとも一部を加工用素材の厚さの厚肉にし、リード部をハーフエッチングにて薄肉にしている端子部材110を、複数個と、センターパッド配列の半導体素子120とを用い、半導体素子120の所定の端子部121と所定の端子部材の内部端子部111とをワイヤボンディング接続して、樹脂封止した平板状方形の樹脂封止型半導体装置であり、各端子部材110を同じ向きにし、外部端子部112の表裏の面およびリード部114のエッチング面114aが、それぞれ、一平面上に、揃うようにし、周辺部に、内部端子部側を内側に向けて、各端子部材を配している。
第1の例は図1に示す本発明に関わる樹脂封止型半導体装置の第1例とは異なり、内部端子部111の端子面をリード部のエッチング面114aと対向する面に設け、且つ、リード部114のハーフエッチング面114a側の面を半導体素子120の端子面120aに載せるLOC(Lead On Chip)構造のものである。
そして、第1例と同様に、各端子部材110のハーフエッチング面114a側の外部端子部の厚肉部の一面と外側側面とを、それぞれ端子面112a,112bとして露出させ、これ以外を樹脂中にして樹脂封止されている。
第1の例も端子部材110の加工用素材(図示していない)の一面側が、露出するようにして樹脂封止していることにより、薄型化が達成できる。
半導体素子は加工用素材から端子部材のハーフエッチングの深さよりも薄いものが用いられる。
例えば、端子部材110の加工用素材の板厚を0. 2mm厚とした場合、0. 1mm〜0. 025mm厚の半導体素子を用いることにより、薄型化が達成できる。
また、本例においても、ワイヤボンディング接続をとっていることにより、接続作業性を良いものとし、且つ、接続信頼性を良いものとしている。
また、本例も、半導体素子へのリード部の搭載向きが第1例とは異なるが、基本的には、ほぼ同じように面付け状態で作製でき、量産性に適した構造と言える。
また、図1に示す本発明に関わる樹脂封止型半導体装置の第1例と同様に、樹脂封止工程(モールド工程)においては、特別な形状にキャビティーを設ける必要はなく、平板状のものでその両側を抑えた状態でモールドが簡単に行える構造で、設備の面からも好ましい構造と言える。
各部については図1に示す本発明に関わる樹脂封止型半導体装置の第1例と同じものが用いられる。
Next, a first example of an embodiment of the resin-encapsulated semiconductor device of the present invention will be described with reference to FIG.
Resin-sealed semiconductor device of the first embodiment, as in the first example of the resin-encapsulated semiconductor device according to the present invention shown in FIG. 1, the external terminal section 112 for connection to an external circuit, the semiconductor element A lead member 114 that includes an internal terminal portion 111 for connection with a lead member 114 as a part thereof is integrally connected to a terminal member having the same shape, and a processing material (see FIG.

Each terminal member 110 is oriented in the same direction so that the front and back surfaces of the external terminal portion 112 and the etching surface 114a of the lead portion 114 are aligned on one plane, and the inner terminal portion side is inward in the peripheral portion. Each terminal member is arranged.
The first example is different from the first example of the resin-encapsulated semiconductor device according to the present invention shown in FIG. 1, provided the terminal surfaces of the internal terminal portion 111 on the etched surface 114a which faces the lead portion, and The lead 114 has a LOC (Lead On Chip) structure in which the surface on the half-etched surface 114 a side of the lead portion 114 is placed on the terminal surface 120 a of the semiconductor element 120.

The resin is sealed.
In the first example as well, the one side of the processing material (not shown) of the terminal member 110 is resin-sealed so as to be exposed, thereby achieving a reduction in thickness.
As the semiconductor element, a material thinner than the half etching depth of the terminal member is used.
For example, when the thickness of the processing material of the terminal member 110 is 0.2 mm, it is possible to reduce the thickness by using a semiconductor element having a thickness of 0.1 mm to 0.025 mm.
Also in this example, the wire bonding connection is used, so that the connection workability is good and the connection reliability is good.
Although this example is different from the first example in the mounting direction of the lead portion to the semiconductor element, it can be basically manufactured in the same imposition state and can be said to be a structure suitable for mass production.
Further, as in the first example of the resin-encapsulated semiconductor device according to the present invention shown in FIG. 1, in the resin-encapsulation process (molding process), it is not necessary to provide a cavity in a special shape, and a flat plate-like shape It can be said that it is a preferable structure from the viewpoint of equipment because it can be easily molded with both sides held down.

(Fig. 9 (b))
As a result, a processed sheet 310A is obtained in which the arrangement of the terminal member corresponding to the arrangement of the terminal member of one resin-encapsulated semiconductor device is taken as one unit, and this is connected and faced by the support portion 335.
As the processing material 310, Cu, Cu-based alloy, 42 alloy (Ni42% -Fe alloy) or the like is used, and ferric chloride solution is used as the etching solution.

Next, the front and back are sandwiched between flat plates 371 and 372 for fixing the mold, and the entire processed sheet 310A is molded collectively. (Fig. 10 (g))
Note that the support portion 335 that supports the terminal member 330 of the processed sheet 310A is provided with a through hole or the like, and has a shape that allows resin for molding between impositions to pass through during molding. .
In this way, the resin-encapsulated semiconductor device of the first example shown in FIG. 1 can be manufactured.

次いで、表裏のモールド固定用の平板371、372を除去し、更にテープ360を除去し(図10(h))、切断用のテープ365を貼り(図10(i))、該切断用のテープ365とは反対側からダイシングソー(図示していない)にて切断して、樹脂封止型半導体装置を1個づつに個片化して得る。(図10(j))

By cutting with a dicing saw (not shown) from the side opposite to 365, the resin-encapsulated semiconductor devices are obtained as individual pieces. (Fig. 10 (j))
The cutting state by a dicing saw (not shown) is, for example, as shown in FIG. 11 (a) or FIG. 11 (b).
In FIG. 11, the unit resin-encapsulated semiconductor device 401 is a region separated from each other by a cutting line 485, which is not shown here for the sake of easy understanding. The part 335 is cut at the recess 334.
