Abstract
【解決手段】本実施形態によれば、半導体装置の製造方法が提供される。半導体装置の製造方法においては、半導体基板の表面とサポート基板20の表面とを接着剤15を介して貼り合わせる。前記サポート基板の周辺部の一部に撥水処理を行い、前記一部に前記接着剤の端面に接するように撥水領域22を形成する。ウェットエッチングにより、前記半導体基板を裏面側から加工する。
【選択図】 図6
Description
本実施形態は、スピン方式のウェットエッチングによる半導体基板(デバイスウェハ)の薄膜化工程において、半導体基板を支持するサポート基板の周辺部を撥水処理することにより、エッチング液のサポート基板への回り込みを抑制する例である。
まず、図1を用いて、本実施形態に係る半導体装置の製造フローについて説明する。
次に、図2乃至図9を用いて、本実施形態に係る半導体装置におけるTSV形成の前工程(図1におけるステップS1〜ステップS6)について説明する。
上記実施形態によれば、半導体基板10のスピン方式のウェットエッチングによる薄膜化工程の前工程として、半導体基板10を支持するサポート基板20(および/または保護膜21)の周辺部を撥水処理する。これにより、エッチング液によってサポート基板20がエッチングされることを抑制することができる。すなわち、サポート基板20の形状変化といったサポート基板20へのダメージを抑制することができる。その結果、サポート基板20の繰り返し使用回数を増大することができる。
