Description

【0001】
【発明の属する技術分野】
本発明は、例えば基板の被めっき面にめっきを施すめっき装置に係り、特に半導体ウエハ等の基板の表面に、パッケージの電極等と電気的に接続するバンプ(突起状電極)を形成するのに使用されるめっき装置に関する。
【0002】
【従来の技術】
例えば、TAB(Tape Automated Bonding)やフリップチップにおいては、配線が形成された半導体チップの表面の所定箇所(電極)に金、銅、はんだ、或いはニッケル、更にはこれらを多層に積層した突起状接続電極(バンプ)を形成し、このバンプを介してパッケージの電極やTAB電極と電気的に接続することが広く行われている。このバンプの形成方法としては、電気めっき法、蒸着法、印刷法、ボールバンプ法といった種々の手法があるが、半導体チップのI/O数の増加、細ピッチ化に伴い、微細化が可能で性能が比較的安定している電気めっき法が多く用いられるようになってきている。
【0003】
この電気めっき法を用いて基板表面の所定の位置にバンプを形成する一般的な形成方法を以下に説明すると、先ず、スパッタ法や蒸着法等で基板の表面にシード層を形成し、このシード層の上にレジストを塗布してレジスト膜を形成した後、露光及び現像を行って、レジスト膜の所定の位置に開口部を形成する。そして、このレジスト開口部内に、電気めっき法を用いて、例えばAuやCu等のバンプ材料となるめっき金属を析出させ成長させる。次に、不要となったレジスト膜を剥離除去し、しかる後、バンプ以外の不要なシード層をエッチング除去する。そして、必要に応じて、バンプのリフローを行って、球状のバンプにする。
【0004】
従来、この種の一連のバンプ形成処理に使用されるめっき装置は、一般に、めっき処理を行うめっき処理部と、基板の洗浄やめっきの前処理等のめっきに付帯する処理を行う付帯処理部と、これらの各処理部との間で基板の受渡しを行う搬送ロボットとを備えている。そして、所定の位置にレジスト開口部を予め形成した基板を用意し、この基板を収納した基板カセットから、基板を一枚ずつ取出し、この基板のレジスト開口部内にAuやCu等のバンプ材料となるめっき金属を成長させ、洗浄及び乾燥等のめっき後処理を施した後、基板カセットに戻すように構成されていた。
【0005】
そして、めっき装置でめっき処理が施されて基板カセットに収納された基板は、基板カセットに収納されたまま、次工程のレジスト剥離装置やエッチング装置等に順次搬送され、これらの各装置で、レジスト膜の隔離除去やシード層のエッチング除去等の各処理が施される。
【0006】
【発明が解決しようとする課題】
しかしながら、バンプ形成処理に使用される従来のめっき装置にあっては、前述のように、例えば製造リードタイムを考慮し、少品種・大量生産に適すように、めっき処理までを行うように構成されていたため、バンプ完成までの一連の処理を連続して行うことができず、その後の処理に使用されるレジスト剥離装置やエッチング装置等を含めた装置全体としての大型化に繋がり、しかもフレキシビリティーに欠けるといった問題があった。
【0007】
本発明は上記事情に鑑みて為されたもので、例えばバンプ形成処理等の一連のめっき処理を含む処理を連続的に行うことができて、装置全体としての省スペース化を図ることができ、しかも多品種・少量生産に適しためっき装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
請求項1に記載の発明は、レジストを使用して基板表面の所定の位置にめっき金属を析出させてめっき膜を形成するめっき装置であって、めっき処理を行うめっきモジュールを備えためっき装置に、独立したモジュールからなるレジスト剥離モジュールとエッチングモジュールを一体に組み込んだことを特徴とするめっき装置である。
【0009】
このように、めっき装置に独立したモジュールからなるレジスト剥離モジュールとエッチングモジュールを一体に組み込むことで、めっき処理後のレジスト膜の剥離除去処理及びシード層のエッチング除去処理を連続的に行うことができ、しかも、目的とするめっきにより柔軟に対応することができる。
【0010】
請求項2に記載の発明は、基板を洗浄する洗浄モジュールと、めっきの前処理を行う前処理モジュールを更に有することを特徴とする請求項1記載のめっき装置である。
【0011】
請求項3に記載の発明は、基板表面の所定の位置に形成した前記めっき膜のリフローを行うリフローモジュールを更に有することを特徴とする請求項1または2記載のめっき装置である。これにより、めっき膜のリフローが必要な場合に、このめっき膜のリフロー処理を連続的に行うことができる。
請求項4に記載の発明は、前記めっき膜はバンプであることを特徴とする請求項1乃至3のいずれかに記載のめっき装置である。
【0012】

【0015】
めっきモジュール16は、基板表面のレジスト開口部に、例えば電気めっき処理を施すモジュールである。レジスト剥離モジュール18は、基板表面に残った不要となったレジスト膜を剥離除去するモジュールである。エッチングモジュール20は、基板表面に形成されたバンプ等のめっき膜以外の不要なシード層をエッチング除去するモジュールである。リフローモジュール22は、基板を加熱して、基板表面に形成されたバンプ等のめっき膜を溶融させ半球状に(リフロー)するモジュールである。

【0017】
そして、このカセット台10に搭載した基板カセットから、第1搬送ロボット24で基板Wを1枚取出して、洗浄モジュール12に搬送し、この洗浄モジュール12で基板Wの表面を純水で洗浄する。この洗浄後の基板Wを第2搬送ロボット26で前処理モジュール14に搬送し、この前処理モジュール14で、例えば基板Wを硫酸や塩酸などの薬液中に浸漬させたり、めっき液の一成分である前処理液(プレディップ液)を基板Wの表面に均一に塗布したりする前処理を行う。
【0018】

【0019】
そして、このめっき後の基板Wを、必要に応じて洗浄モジュール12で洗浄した後、第2搬送ロボット26でレジスト剥離モジュール18に搬送し、このレジスト剥離モジュール18で、基板Wを、例えば温度が50〜60℃のアセトン等の溶剤に浸漬させて、図2(c)に示すように、基板W上のレジスト膜502を剥離除去する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to, for example, a plating apparatus for plating a surface to be plated of a substrate, and particularly to forming a bump (protruding electrode) on a surface of a substrate such as a semiconductor wafer so as to be electrically connected to an electrode of a package. It relates to the plating equipment used.
[0002]
[Prior art]
For example, in a TAB (Tape Automated Bonding) or a flip chip, gold, copper, solder, or nickel, or a protruding connection in which these are stacked in a multilayer at predetermined positions (electrodes) on the surface of a semiconductor chip on which wiring is formed. 2. Description of the Related Art It is widely practiced to form electrodes (bumps) and electrically connect to electrodes of a package or TAB electrodes via the bumps. As a method of forming the bump, there are various methods such as an electroplating method, a vapor deposition method, a printing method, and a ball bump method. However, with the increase in the number of I / Os and the fine pitch of the semiconductor chip, miniaturization is possible. Electroplating methods, which have relatively stable performance, have been increasingly used.
[0003]
A general method of forming a bump at a predetermined position on the substrate surface by using the electroplating method will be described below. First, a seed layer is formed on the surface of the substrate by sputtering, vapor deposition, or the like. After applying a resist on the layer to form a resist film, exposure and development are performed to form openings at predetermined positions in the resist film. Then, a plating metal, such as Au or Cu, serving as a bump material is deposited and grown in the resist opening using an electroplating method. Next, the unnecessary resist film is peeled off, and thereafter, unnecessary seed layers other than the bumps are removed by etching. Then, if necessary, the bumps are reflowed into spherical bumps.
[0004]
Conventionally, a plating apparatus used for a series of bump forming processes of this type generally includes a plating section for performing a plating process, and an auxiliary processing section for performing a process accompanying the plating such as cleaning of a substrate and pretreatment of plating. And a transfer robot that transfers a substrate to and from each of these processing units. Then, a substrate in which a resist opening is formed in advance at a predetermined position is prepared, and the substrates are taken out one by one from a substrate cassette containing the substrate, and a bump material such as Au or Cu is formed in the resist opening of the substrate. It has been configured to grow a plated metal, perform post-plating treatment such as washing and drying, and then return to the substrate cassette.
[0005]
The substrate, which has been subjected to the plating process in the plating apparatus and stored in the substrate cassette, is sequentially transported to the resist stripping apparatus or the etching apparatus in the next process while being stored in the substrate cassette. Various processes such as isolation removal of the film and etching removal of the seed layer are performed.
[0006]
[Problems to be solved by the invention]
However, in the conventional plating apparatus used for the bump formation processing, as described above, for example, in consideration of the manufacturing lead time, the plating apparatus is configured to perform the plating processing so as to be suitable for a small number of kinds and mass production. As a result, a series of processes until the completion of the bump cannot be performed continuously, which leads to an increase in the size of the entire apparatus including a resist stripping apparatus and an etching apparatus used in the subsequent processing, and furthermore, flexibility. There was a problem that lacked.
[0007]
The present invention has been made in view of the above circumstances, for example, it is possible to continuously perform a process including a series of plating processes such as a bump forming process, it is possible to achieve space saving as a whole apparatus, Moreover, it is an object of the present invention to provide a plating apparatus suitable for high-mix low-volume production.
[0008]
[Means for Solving the Problems]
The invention according to claim 1 is a plating apparatus for forming a plating film by depositing a plating metal at a predetermined position on a substrate surface using a resist, the plating apparatus having a plating module for performing a plating process. A plating apparatus characterized in that a resist stripping module and an etching module, each of which is an independent module, are integrally incorporated.
[0009]
In this way, by integrally incorporating the resist stripping module and the etching module, which are independent modules, in the plating apparatus, the stripping removal process of the resist film after the plating process and the etching removal process of the seed layer can be continuously performed. Moreover, it is possible to flexibly cope with the intended plating.
[0010]

Thereby, when the reflow of the plating film is necessary, the reflow processing of the plating film can be continuously performed.
The invention according to claim 4 is the plating apparatus according to any one of claims 1 to 3, wherein the plating film is a bump.
