Definitions
- the present invention relates to a filling method and a filling apparatus, and more particularly to a filling method and a filling apparatus for filling a filling material in a minute space of a wafer.
- Japanese Patent No. 4130649 discloses a method for filling a via in which a via (fine space) provided in a wafer is filled with paste.
- the wafer processing apparatus further comprises a pressure reduction process for evacuating the vacuum, and a filling process for pouring the paste on the wafer side and pressing the paste into the via provided in the wafer by pressing with a piston.
- the O-ring is arranged to cover a part of the wafer.
- Patent No. 4130649 gazette
- a squeegee method (a method of scraping the silica fine powder with a squeegee in a state where a squeegee such as a spatula is in contact with the surface of the wafer) is used.
- a squeegee method a method of scraping the silica fine powder with a squeegee in a state where a squeegee such as a spatula is in contact with the surface of the wafer.
- this filling method has a problem that it is difficult to sufficiently impregnate liquid glass to the bottom of the via (the via is not sufficiently filled). For this reason, when baking and solidifying liquid glass after impregnation, voids or sinks (depressions) or the like occur in the vias.
- the aspect ratio (depth / width (diameter)) of depth and width (diameter) of the fine space is 5 or more
- the width (diameter) of the minute space becomes larger, there is a problem that the filling takes time.
- the present invention has been made to solve the problems as described above, and one object of the present invention is to quickly fill the filling material under the same conditions even if fine spaces of various shapes are mixed in the wafer. It is an object of the present invention to provide a filling method and a filling device capable of filling a sufficiently fine space.
- the filling method according to the present invention is a filling method for filling a filling material in a minute space provided in a wafer, and a pressure reducing step of reducing the pressure in a processing chamber on which the wafer is placed In the processing chamber, the step of contacting the surface of the wafer with the filler material in the processing chamber, the step of differential pressure-filling the filler material in the fine space of the wafer by pressurizing the entire surface of the filler material opposite to the wafer, And B. firing the filler material throughout the entire process.
- the “fine space” means a fine groove having a width of 100 ⁇ m or less and a fine through hole and a non-through hole having a hole diameter of 100 ⁇ m or less mainly formed in the wafer by etching.
- the filling material is used under the same conditions. It is possible to fill the minute space quickly and sufficiently. This has been confirmed by experiments.
- the filling method according to the present invention includes a filling step of pressing the entire surface of the filling material opposite to the wafer, and a firing step of firing the filling material over the entire wafer.
- This enables not only the filling of the filling material into the fine space quickly, but also the filling material can be fired in a single firing step over the entire wafer, so the steps from filling to firing of the filling material can be quickened. Can be done.
- Can As a result, it is possible to suppress the occurrence of variations in the properties of the fired filling material in the fine space.
- a space is provided to evacuate by differentially filling the filling material into the fine space of the wafer by pressurizing the entire surface of the filling material opposite to the wafer.
- the filling material can be filled in the fine space of the wafer without using an O-ring for separating the
- O-ring for separating the
- the unevenness is formed on the surface of the wafer in contact with the O-ring, the O-ring and the wafer can not be sufficiently adhered due to the unevenness of the wafer.
- the present invention since it is not necessary to bring the O-ring and the wafer into close contact with each other, even if the wafer is uneven, filling the filling material in the fine space of the wafer is ensured. Can.
- the pressure reduction step includes the step of reducing the pressure in the processing chamber to 100 Pa or more and 2000 Pa or less.
- the differential pressure can be reliably generated in the filling step after the depressurizing step, and the filling material can be differentially filled in the minute space.
- the sealing structure of the processing chamber can be simplified and the configuration of the devices installed in the processing chamber can be simplified as compared to the case where the pressure is greatly reduced to less than 100 Pa.

Abstract
Description
まず、図1~図5を参照して、第1実施形態による充填装置100について説明する。
第1実施形態による充填装置100は、ウェハ1(図2参照)に形成された環状溝などの微細空間2(図2参照)に、充填材料3(図6参照)を充填して焼成する装置である。
充填部10は、いわゆる真空スピンコータである。つまり、充填部10は、図3に示すように、外観が円柱状の処理室11と、処理室11内の圧力を低くするための真空ポンプ12と、処理室11内に配置されるウェハ支持部13および充填材料滴下部14とを含んでいる。なお、充填材料滴下部14は、本発明の「充填材料配置部」の一例である。処理室11は、開閉可能に構成されているとともに、真空ポンプ12を駆動させることによって、内部空間を約100Pa以上で、かつ、大気圧よりも低い減圧環境下にすることが可能である。
焼成部20は、内部の空気清浄度を高い状態で維持可能ないわゆるクリーンオーブンである。焼成部20は、図4に示すように、処理室21と、処理室21内の圧力を高くするための加圧器22と、処理室21内に配置されるウェハ支持部23およびヒータ24とを含んでいる。処理室21は、開閉可能に構成されているとともに、加圧器22を駆動させて処理室21内にガスを導入することによって、内部空間を大気圧より高い高圧環境下にすることが可能である。なお、加圧器22により処理室21内に導入されるガスは、窒素ガスなどの不活性ガスが好ましい。ヒータ24は、ウェハ1を約250℃以下の温度に昇温させることが可能である。また、ヒータ24は、図示しない温度センサやCPUなどを有しており、その結果、図5に示す焼成工程における温度制御のように、昇温速度の制御や所定の温度での維持などを行うことが可能なように構成されている。なお、図5の焼成工程における温度制御の詳細については、後述する。
剥離部30では、剥離剤を用いてウェハ1上のマスク4(図2(b)参照)が除去される。なお、充填材料3のうち架橋硬化されたAL-X2000シリーズは、AZ100REMOVERにあまり溶解しないため、充填材料3としてAL-X2000シリーズを用いる場合には、剥離剤としてAZ100REMOVERを用いるのが好ましい。また、充填材料3のうち架橋硬化されたBM302およびBL301は、NMPに略溶解しないため、充填材料3としてBM302やBL301を用いる場合には、剥離剤としてNMPを用いるのが好ましい。残さ除去・研磨部40では、CMP(化学機械研磨)やポリッシャーなどの機械研磨によってウェハ1の形成面1aが研磨される。洗浄・乾燥部50は、一般的なスピン洗浄機である。洗浄・乾燥部50では、ウェハ1を回転させながら純水を滴下することによって、ウェハ1の形成面1a全面が洗浄される。その後、洗浄・乾燥部50において、窒素ブローしながらウェハ1を高速回転させる事で、ウェハ1の形成面1aがむらなく乾燥される。
次に、図1~図6を参照して、第1実施形態による充填装置100における充填プロセスについて説明する。
まず、搬入・搬出部60により搬入されたウェハ1が、搬送部70により、充填部10の処理室11内に搬送される。その際、ウェハ1は、形成面1aが上面(Z1側の面)になるようにウェハ支持部13(図3参照)の所定の位置に載置される。そして、図3(a)に示すように、ウェハ1を処理室11の内部に収納した状態で、処理室11内を気密状態にする。その後、真空ポンプ12を用いて、処理室11内を減圧環境にする(減圧工程)。これにより、ウェハ1の微細空間2内も減圧される。なお、処理室11内の減圧環境は、約100Pa以上約2000Pa以下の減圧環境であればよく、好ましくは、約700Pa以上約1000Pa以下の減圧環境であるのが好ましい。なお、約100Pa以上約2000Pa以下の減圧(低圧)は、JIS Z 8126-1 真空技術-用語-に記載された低真空領域に含まれる。
その後、ウェハ1は、搬送部70により、大気圧に開放した処理室11内から、焼成部20の処理室21内でウェハ支持部23に載置される。そして、図4に示すように、ウェハ1を処理室21内に収納した状態で、処理室21内を気密状態にする。その後、加圧器22を用いて、処理室21内を大気圧より大きく約0.5MPa以下の高圧環境にする。これにより、さらに確実に、非充填空間2dに充填材料3が充填されるとともに、充填材料3の液面3aがさらに加圧されて、体積減少した分の充填材料3の補充が速やかに行われる。
処理室21内を大気圧に開放した後、搬送部70により、ウェハ1が焼成部20から剥離部30に搬送される。そして、図6に示すように、剥離部30において剥離剤を用いてウェハ1上のマスク4が除去される(剥離工程)。その際、マスク4とともに、マスク4上の焼成された充填材料3bも合わせて除去される。その後、残さ除去・研磨部40に搬送されてウェハ1の形成面1aが研磨される(残さ除去・研磨工程)。これにより、微細空間2からはみ出して焼成された充填材料3bが除去されて、形成面1aが平滑化される。そして、洗浄・乾燥部50に搬送されてウェハ1が洗浄および乾燥される(洗浄・乾燥工程)。最後に、ウェハ1は、搬入・搬出部60により搬出される。
次に、図1、図2、図6および図7を参照して、第2実施形態による充填装置200について説明する。この充填装置200では、上記第1実施形態による充填装置100とは異なり、充填部110において、ローラ114を用いてウェハ1に充填材料3を塗布する例について説明する。なお、第1実施形態と同一の構成については、同一の符号を付すとともに説明を省略する。
第2実施形態による充填装置200は、図1に示すように、充填部110と、焼成部20と、剥離部30と、残さ除去・研磨部40と、洗浄・乾燥部50とをウェハ処理部として備えている。充填部110は、図7に示すように、処理室11と、真空ポンプ12と、処理室11内に配置されるウェハ支持部13およびローラ114とを含んでいる。なお、ローラ114は、本発明の「充填材料配置部」および「膜厚調整用の部材」の一例である。
次に、図1、図6および図7を参照して、第2実施形態による充填装置200における充填プロセスについて説明する。
次に、図8~図11を参照して、第3実施形態による充填装置300について説明する。
第3実施形態による充填装置300は、図8に示すように、充填部210と、焼成部20と、残さ除去・研磨部40と、洗浄・乾燥部50とをウェハ処理部として備えている。つまり、上記第1実施形態による充填装置100と異なり、剥離部は設けられていない。この充填装置300では、ウェハ201(図9参照)は、搬送部70により、充填部210、焼成部20、残さ除去・研磨部40および洗浄・乾燥部50をこの順で搬送される。
次に、図11を参照して、第3実施形態による充填装置300における充填プロセスについて説明する。
次に、図5、図9、図10および図12を参照して、本発明の効果を確認するために行った充填状態の確認実験について説明する。
この確認実験では、図9に示すような、複数の微細空間202が形成されたウェハ201を準備した。具体的には、複数の微細空間202として、2μmの径W1および20μmの深さL1を有する非貫通穴(アスペクト比=10)と、10μmの径W1および50μmの深さL1を有する非貫通穴(アスペクト比=5)と、1μmの幅W1および17μmの深さL1を有する環状溝(アスペクト比=17)と、4μmの幅W1および24μmの深さL1を有する環状溝(アスペクト比=6)と、2μmの幅W1および20μmの深さL1を有する環状溝(アスペクト比=10)とが形成されたウェハ201を準備した。
図12に示す断面観察の結果としては、実施例では、1枚のウェハ201に形成された複数の非貫通穴および環状溝の各々において、焼成された充填材料が十分に充填されているのが確認できた。また、各々の非貫通穴内および環状溝内において、底面から開口までの全体に焼成された充填材料が十分に充填されており、ボイドの発生は観察されなかった。このことから、実施例の充填方法では、ウェハに幅(径)や深さが異なる様々な形状の微細空間が混在しても、同一条件で充填材料を迅速かつ十分に微細空間に充填することが可能なことが確認できた。また、各々の非貫通穴および環状溝の開口まで焼成された充填材料が充填されていることから、焼成工程において、非貫通穴内や環状溝内の充填材料の減少分を補填するようにウェハの形成面から充填材料が補填されたと考えられる。
なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更(変形例)が含まれる。
