Description
(2)レーザー加工溝を形成する際に機能層の除去が不十分であると切削ブレードのズレや倒れが発生してデバイスの機能層に剥離が生じる。
(3)切削ブレードの幅を超える範囲でレーザー加工溝を形成するために、分割予定ラインの幅を広くする必要があり、ウエーハに形成されるデバイスの数が減少する。
(4)機能層の表面にはSiO2、SiN等を含むパシベーション膜が形成されているため、レーザー光線を照射するとパシベーション膜を透過して機能層の内部に達する。この結果、機能層の内部に達したレーザー光線のエネルギーが逃げ場を失い、回路が形成され密度が低いデバイス側に加工が広がる所謂アンダーカット現象が発生する。
実施形態に係るウエーハの加工方法を、図1から図7に基づいて説明する。図1は、実施形態に係るウエーハの加工方法の保護部材貼着工程の概要を示す斜視図、図2は、実施形態に係るウエーハの加工方法の切削溝形成工程の概要を示す斜視図、図3は、実施形態に係るウエーハの加工方法の切削溝形成工程の概要を示す断面図、図4は、実施形態に係るウエーハの加工方法の切削溝形成工程の概要を示す他の断面図、図5は、実施形態に係るウエーハの加工方法のウエーハ支持工程の概要を示す図、図6は、実施形態に係るウエーハの加工方法の機能層切断工程の概要を示す斜視図、図7は、実施形態に係るウエーハの加工方法が施されたウエーハの要部の断面図である。

- 低誘電率絶縁体被膜からなる絶縁膜と回路を形成する機能膜が積層されかつ基板の表面に積層された機能層に格子状に形成された複数の分割予定ラインによって区画された複数の領域にデバイスが形成されたウエーハを、分割予定ラインに沿って分割するウエーハの加工方法であって、
ウエーハを構成する機能層の表面に保護部材を貼着する保護部材貼着工程と、
該保護部材貼着工程が実施されたウエーハの該保護部材側をチャックテーブルに保持し、基板の裏面側から分割予定ラインと対応する領域に切削ブレードを位置付けて機能層に至らない一部を残して切削溝を形成する切削溝形成工程と、
該切削溝形成工程が実施されたウエーハを構成する基板の裏面にダイシングテープを貼着しダイシングテープの外周部を環状のフレームによって支持するとともに、該保護部材を剥離するウエーハ支持工程と、
該ウエーハ支持工程が実施されたウエーハを構成する機能層に形成された分割予定ラインに沿ってレーザー光線を照射し、該切削溝に達するレーザー加工溝を形成することで、該機能層をアブレーション加工して切断する機能層切断工程と、を含み、
該切削溝形成工程においては、ウエーハの外周領域に未切削部を残し前記分割予定ラインに沿って該切削溝を形成することを特徴とするウエーハの加工方法。
