Description

本発明は、金線に関し、特に、半導体パッケージ工程における合金線およびその製造方法に関する。   The present invention relates to a gold wire, and more particularly to an alloy wire in a semiconductor package process and a method for manufacturing the same.

半導体デバイスのパッケージ工程において、金線がチップおよび基板に連接される。金線によりチップと基板とが電気的に接続され、チップと基板との間での信号および電流伝達を行う。   In the semiconductor device packaging process, the gold wire is connected to the chip and the substrate. The chip and the substrate are electrically connected by the gold wire, and signals and current are transmitted between the chip and the substrate.

金線の負荷強度、延伸性、湾曲性、融点、電気性、硬度、ICチップとの接続能力など主要な特性は、用いた材料と関係がある。上記の特性は、半導体デバイスの寿命および安定性に悪影響を及ぼす。チップおよび基板の形態により、用いられる金線の規格も異なる。   Main characteristics such as load strength, stretchability, bendability, melting point, electrical property, hardness, and ability to connect to an IC chip are related to the materials used. The above characteristics adversely affect the lifetime and stability of the semiconductor device. The standard of the gold wire used varies depending on the form of the chip and the substrate.

従来の金線は、主に純金から製造されている。純金から製造された金線は、比較的良好な延伸性および導電性という物理的性質を有する。しかし、純金材料から造られる金線は、コストが高いため、半導体デバイスのコストを増加させた。そのため、純金金線と同等の効果を有し、大幅にコストを下げる金線を提供するのが本発明の課題である。
一方、先行技術として、例えば特許文献1は、金と、銀と、ゲルマニウム,シリコン,アルミニウム,又は銅のいずれか1つと、からなる金合金ボンディングワイヤの組成を開示している。
Conventional gold wires are mainly manufactured from pure gold. Gold wires made from pure gold have the physical properties of relatively good stretchability and conductivity. However, a gold wire made from a pure gold material has a high cost, thus increasing the cost of a semiconductor device. Therefore, it is an object of the present invention to provide a gold wire that has an effect equivalent to that of a pure gold wire and greatly reduces the cost.
On the other hand, as a prior art, for example, Patent Document 1 discloses a composition of a gold alloy bonding wire made of gold, silver, and any one of germanium, silicon, aluminum, or copper.

特許第4130843号公報Japanese Patent No. 4130843

上述の目的を達成するため、本発明は、実質上銀、金、パラジウムからなる合金線およびその製造方法を提供する。本発明の合金線およびその製造方法は、a工程において、8.00〜30.00重量%の金および66.00〜90.00重量%の銀の成分を含んだ主要金属材料が提供される。b工程において、主要金属材料が真空溶炉内に入れられ、真空溶炉内に0.01〜6.00重量%のパラジウムを含んだ副次的原料金属材料が混入されると、金銀パラジウム合金溶解液が作り出される。c工程において、金銀パラジウム合金溶解液が連続して鋳造され、引き伸ばされて金銀パラジウム合金線材が形成される。d工程において、金銀パラジウム合金線材が引き伸ばされて所定の線径の金銀パラジウム合金線に加工される。 In order to achieve the above object, the present invention provides an alloy wire substantially composed of silver, gold, and palladium and a method for producing the same. Alloy wire and a manufacturing method of the present invention, in a process, the main metallic material is provided that includes a component of 8.00 to 30.00 wt% of gold and from 66.00 to 90.00 wt% silver. In step b, when the main metal material is placed in a vacuum furnace and a secondary raw metal material containing 0.01 to 6.00 wt% palladium is mixed in the vacuum furnace, a gold-silver-palladium alloy solution is produced. It is. In step c, the gold-silver-palladium alloy solution is continuously cast and stretched to form a gold-silver-palladium alloy wire. In step d, the gold-silver-palladium alloy wire is stretched and processed into a gold-silver-palladium alloy wire having a predetermined wire diameter.

本発明の合金線は、金、銀およびパラジウムの三種の金属から製造され、純金金線と同等の効果を有し、大幅にコストを削減することができる。   The alloy wire of the present invention is manufactured from three kinds of metals, gold, silver and palladium, and has the same effect as a pure gold wire, and can greatly reduce the cost.

本発明の一実施形態による合金線の製造方法を示す流れ図である。2 is a flowchart showing a method of manufacturing an alloy wire according to an embodiment of the present invention. 図1の細部を示す流れ図である。2 is a flowchart showing details of FIG. 1.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1および図2を参照する。図1は、本発明の一実施形態による合金線の製造方法を示す流れ図である。図2は、図1の細部を示す流れ図である。図1および図2に示すように、本発明の合金線の製造方法は、まず、工程100において、金および銀の成分を含んだ主要金属材料が提供される。   Please refer to FIG. 1 and FIG. FIG. 1 is a flowchart showing a method of manufacturing an alloy wire according to an embodiment of the present invention. FIG. 2 is a flowchart showing details of FIG. As shown in FIG. 1 and FIG. 2, in the method of manufacturing an alloy wire of the present invention, first, in step 100, a main metallic material containing gold and silver components is provided.

工程102において、溶解精錬が行われる。金および銀の成分を含んだ主要金属材料が真空溶炉内に入れられ(工程102a)、次に、真空溶炉内にパラジウムを含んだ副次的原料金属材料が混入され、溶解される(工程102b)。これにより、真空溶炉が金銀パラジウム合金溶解液を作り出す(工程102c)。金銀パラジウム合金溶解液は、金が8.00〜30.00重量%、銀が66.00〜90.00重量%、パラジウムが0.01〜6.00重量%含まれる。   In step 102, melt refining is performed. The main metallic material containing the components of gold and silver is put in the vacuum furnace (step 102a), and then the secondary raw metallic material containing palladium is mixed and melted in the vacuum furnace (see FIG. Step 102b). As a result, the vacuum furnace creates a gold-silver-palladium alloy solution (step 102c). The gold-silver-palladium alloy solution contains 8.00 to 30.00% by weight of gold, 66.00 to 90.00% by weight of silver, and 0.01 to 6.00% by weight of palladium.

金銀パラジウム合金溶解液が連続して鋳造され、引き伸ばされて線径が4〜8 mmの金銀パラジウム合金線材が形成される(工程102d)。リールにより金銀パラジウム合金線材が巻き取られる(工程102e)。成分比率が正しいか、金銀パラジウム合金線材の成分分析が行われる(工程102f)。   A gold-silver-palladium alloy solution is continuously cast and stretched to form a gold-silver-palladium alloy wire having a wire diameter of 4 to 8 mm (step 102d). The gold-silver-palladium alloy wire is wound up by the reel (step 102e). Whether the component ratio is correct or not is analyzed for the gold-silver-palladium alloy wire (step 102f).

工程104において、鋳造された金銀パラジウム合金線材が引き伸ばされる。線径が4〜8 mmの金銀パラジウム合金線材が第1の太線伸線機により3mm以下に引き伸ばされる(工程104a)。引き続き、第2の太線伸線機により1mm以下に引き伸ばされる(工程104b)。第1の細線伸線機により0.18 mm以下に引き伸ばされる(工程104c)。0.18 mm以下の金銀パラジウム合金線材が第2の細線伸線機(工程104d)、極細線伸線機(工程104e)および超極細線伸線機(工程104f)に順番に引き伸ばされて0.050 mm (2.00mil)〜0.010 mm (0.40mil)の金銀パラジウム合金線となる。   In step 104, the cast gold-silver-palladium alloy wire is drawn. A gold-silver-palladium alloy wire having a wire diameter of 4 to 8 mm is drawn to 3 mm or less by the first thick wire drawing machine (step 104a). Subsequently, it is drawn to 1 mm or less by the second thick wire drawing machine (step 104b). It is drawn to 0.18 mm or less by the first fine wire drawing machine (step 104c). A gold-silver-palladium alloy wire of 0.18 mm or less is drawn in turn to a second fine wire drawing machine (process 104d), an extra fine wire drawing machine (process 104e) and a super extra fine wire drawing machine (process 104f) to 0.050 mm ( 2.00 mil) to 0.010 mm (0.40 mil) gold-silver-palladium alloy wire.

工程106において、金銀パラジウム合金線の表面が洗浄される。   In step 106, the surface of the gold-silver-palladium alloy wire is cleaned.

工程108において、金銀パラジウム合金線に対して、乾燥およびアニール処理が行われることにより、金銀パラジウム合金線の破断強度(Breaking Load)、伸度(Elongation) など物理的特性が所定範囲内に限定されるようにする。   In step 108, the gold-silver-palladium alloy wire is dried and annealed so that the physical properties such as breaking strength and elongation of the gold-silver-palladium alloy wire are limited within a predetermined range. So that

本発金銀パラジウム合金線は、IC、LEDおよびSAWのパッケージにおいて、導線として用いられる   This gold-silver-palladium alloy wire is used as a conductor in IC, LED and SAW packages.

以下、本発明の三つの実施形態を詳細に説明する。   Hereinafter, three embodiments of the present invention will be described in detail.

第1の実施形態
金および銀の成分を含んだ主要金属材料が真空溶炉内に入れられ、次に、真空溶炉内にパラジウムを含んだ副次的原料金属材料が混入されると、真空溶炉が攪拌および溶解を行い、金銀パラジウム合金溶解液を作り出す。金銀パラジウム合金溶解液は、金が30.00重量%、銀が66.00重量%、パラジウムが4.00重量%含まれる。
First Embodiment When a main metal material containing gold and silver components is put in a vacuum furnace, and then a secondary raw metal material containing palladium is mixed in the vacuum furnace, a vacuum is formed. The furnace stirs and melts to produce a gold-silver-palladium alloy solution. The gold-silver-palladium alloy solution contains 30.00% by weight of gold, 66.00% by weight of silver, and 4.00% by weight of palladium.

金銀パラジウム合金溶解液が連続して鋳造され、引き伸ばされて線径が4mmの金銀パラジウム合金線材が形成される。リールにより金銀パラジウム合金線材が巻き取られる。成分比率が正しいか、金銀パラジウム合金線材の成分分析が行われる。   A gold-silver-palladium alloy solution is continuously cast and stretched to form a gold-silver-palladium alloy wire having a wire diameter of 4 mm. A gold-silver-palladium alloy wire is wound up by the reel. The component analysis of the gold-silver-palladium alloy wire is performed to check whether the component ratio is correct.

鋳造された金銀パラジウム合金線材が形成されると、引き伸ばしが行われる。線径が4 mmの金銀パラジウム合金線材が第1の太線伸線機により3mm以下に引き伸ばされる。引き続き、第2の太線伸線機により1mmに引き伸ばされる。第1の細線伸線機により0.18 mmに引き伸ばされる。0.18 mmの金銀パラジウム合金線材が第2の細線伸線機、極細線伸線機および超極細線伸線機に順番に引き伸ばされて0.050 mm〜0.010 mmの金銀パラジウム合金線となる。   When the cast gold-silver-palladium alloy wire is formed, stretching is performed.
